Basic information:

IB-Tron 3100HT thermostat is independent microprocessor thermostat with large LCD display. The thermostat is designed to control work of valves, air dampers, electric air heaters, pumps, fans and other two- and three-point controlled appliances.

IB-Tron 3100HT thermostat allows to control process of heating and cooling. It allows to maintain the desired temperature in building/room according to fixed weekly work scheduler.

IB - Tron 3100HT thermostat allows to save energy costs. Thermostat contributes to protect environment. IB-Tron 3100HT thermostats can be commonly used in: hotels, offices, supermarkets, factories, hospitals, houses and other buildings.


  • Large, blue backlit LCD display which shows current temperature, a day of the week and other information.
  • Easy, intuitive operating and programming.
  • Power supply from network 230V with baterry memory backup.
  • Esthetic and modern design.
  • Blue backlight (backlight is activated by pressing any button and deactivated after set period of inactivity).
  • Comprehensive programming process in a weekly cycle with an accuracy of 1 minute and with possibility of programming four time periods each day.
  • Manual or automatic work mode.
  • Support of two temperature sensor:
    • RT - buit-in room temperature sensor.
    • FT - additional external temperature sensor e.g. floor area, hot water tank.

General considerations:

  • During installation of thermostat, the supply of electricity should be turned off. It’s recommended to entrust the installation a specialized institution.
  • The thermostat gives 230V voltage on the output (support of pump, valve, air damper, heating mat etc.). It’s possible to modify the output - during switching the output terminals can be potential-free shorted (cooperation with a typical gas stove).

Scope of delivery:

  • 1x Thermostat (the main panel)
  • 1x Power module
  • 1x Built-in temperature sens
  • 1x Operating manual

Operating principle:

Thermostat measures the temperature. If this temperature is below the current desired value, the thermostat wants to run heating device to raise temperature to the desired level.

Thermostat may be used in refrigeration by connection cooling device to the contacts OFF of thermostat instead to the contacts ON. Remember, if thermostat is turned off, cooling device will be turned on.

Temperature sensors:

  • The sensors can be extended to any length but we should remember that extension above 10m may cause a deviation of measurement with each meter and falsifying results. Therefore, for distance above 10m device has to be calibrated. Sensors have to be extend of wires: 2x 0,75 mm2.
  • The thermostat is compatible with NTC 10kOhm sensors having the following characteristics:
Temperature [ºC] Resistance [Ohm]
-40 346 405
-30 181 628
-20 99 084

Example of applications:

  • Room thermostat - controlling of temperature in room or entire building (using built-in temperature sensor).
  • Tank thermostat - controlling of temperature in the hot water tank (external temperature sensor).
  • Room thermostat for floor heating- controlling of floor temperature by RT sensor, with a protection against overheating the floor (FT sensor).
  • Pump controller - switching on the pump after exceeding desired temperature by the boiler (cooling, external temperature sensor).


  • IB-Tron 3100HT thermostat consists of two parts: main panel with LCD display, keyboard and power module, with input terminals and output terminals.
  • Control panel is adapted to surface-mounting or to mounting on a standard wiring box (spacing of holes- about 60mm). Power module is predicted to be placed inside this box.
  • Both of modules are connected with each other by five wire cable, with a length of several centimeters.

Power module (with output 230V):


  • 1, 2 - pexternal FT sensor. FT.
  • 3, 4 - power of thermostat 230V AC (3 - wire phase, 4 - wire neutral)
  • 5 - output OFF - on this output will appear phase (short-circuit with terminal 3), if:
    • heating process isn’t implemented;
    • thermostat is turned off;
    • limit of FT sensor is active;
  • 6 - output ON - on this output will appear phase, if heating process is implemented.

Power module (with normally-open contact):



  • 1, 2 - external FT sensor
  • 3, 4 - power of thermostat 230V AC (3 - wire phase, 4 - wire neutral)
  • 5, 6 - these two terminals are shorted when heating process is implemented.

ATTENTION! If you wish to get module with normally-open contact, please indicate about this in the order. The module with output 230V is default supplied.

Example of applications:

In work mode A and with NO contact


Thermostat measures temperature in the representative room by built-in RT sensor. If this temperature is lower than the desired temperature on the thermostat, terminals number 5 and 6 are shorted, which is a signal of switching gas boiler.

In work mode F and with voltage output


Thermostat measures temperature in the hot water tank by FT sensor. If this temperature is lower than the desired temperature on the thermostat, the terminal number 6 is shorted which allows to switching on an electric heater of tank.

In work mode AF and limit of FT temperature


Thermostat measures temperature in the representative room by built-in RT sensor. It controls floor heating by opening and closing the valve with actuator. If RT temperature is lower than the desired temperature on the thermostat, the phase is given on terminal number 6 (opening the valve). When temperature in the room reaches the desired value, the valve is closing (phase is given on terminal number 5).

Additional, during opening the valve, thermostat controls temperature of floor area (FT sensor). If this temperature exceeds the desired limit (e.g. 30 oC), the valve is unconditionally closing - even if temperature in the room (RT sensor) hasn’t reached the desired value yet. The valve will open again after cooling down floor to lower temperature than limit’s temperature.

Turning on thermostat:

When the thermostat is turned off, on display is shown only current temperature and symbol of sensor (RT and FT). Temperature isn’t regulated, relay is set in OFF position.

Configurational menu:

In configurational menu are set parameters of thermostat work.

Thermostat is in configurational mode. Displayed are: inscription ‚Menu’, setting number (from 01 to 17), code shortcut of setting (e.g. ‚LANg’), value and unit of setting.

Thermostat comes out of the configurational menu after a set time of inactivity or after pressing the buttons „P”.


Menu can be in English or Polish language.

Work mode:

Thermostat can work in three modes:

  • A – Device control is based only on built-in temperature sensor (RT)
  • F – Device control is based only on connected external sensor (FT)
  • AF – Device control is based on built-in sensor (RT) and connected additional external sensor (FT). Thermostat is trying to keep desired temperature (RT) but when FT temperature exceeds the set limit, heating device is disabled.


Hysteresis means a difference (in ºC or oF) between threshold of switching on and switching off the actuating device.For example: If set temperature is 20 ºC and hysteresis is set on 0,5 ºC, the actuating (heating) device will be switched on when the temperature falls below 19,5 ºC and device will be switched off when the temperature incresases above 20,5 ºC. Next switching on of actuating device will be again after temperature decrease below 19,5 ºC.

Higher value of hysteresis reduces number of cycles switch on/switch off of actuating device (saving device), but it causes greater temperature fluctuations.


After proper connection the thermostat is ready to work. The thermostat is factory calibrated to work with standard sensor. However, with long wires, displayed temperature may be different from real temperature.

In this case you have to calibrate the device by yourself.

Time of Inactivity:

It is the time, counted from the last press of any button, after which the thermostat comes out from the settings mode of parameters to default mode. Higher value gives the user more time to enter settings.

Displaying temperature in mode AF:

When thermostat works in mode AF (measurement of two temperatures), the user can decide, which temperature has to be displayed (RT, FT or alternately both).

Time of Backlight:

This is a time, after which is fading of LCD backlight, counted from the last press of a button.

The following settings are available:

  • OFF - backlight always turned off;
  • ON - backlight always turned on;
  • value from the range 10 ÷ 60 with step 10 - time of backlight is in seconds.

Temperature units:

User has ability to choose if the temperature must be in oC or oF.

Time Format:

User has ability to choose if the time must be displayed in 12-hour format or 24-hour.


FROST PROTECTION function protects installation against freezing.

IB-TRON 3100HT When measured temperature falls below 5oC, actuating device is activated.

When FROST PROTECTION function is activated, on display is shown snowflake symbol (when thermostat is turned on).

Number of temperature settings:

Thermostat, in automatic mode, has the ability to program four different time segments during the day, each of them with assigned temperature setting. There are two ways of selection the temperature settings:

  • Each segment has independent temperature setting (there are four different temperature settings)
  • There are two different temperature settings: comfortable setting (for segments 1 and 3) and economic setting (for segments 2 and 4);

Test of relay:

Test function allows to manual extortion of relay state , which switches actuating device. We can check a correctness of relay operation as well as connected actuating device without disconnection an electric circuit.

Range of settings:

User can choose range of temperature setting from among three settings:

  • 1 - range 5 ÷ 35 ºC
  • 2 - range 5 ÷ 90 ºC
  • 3 - range -15 ÷ 100 ºC

Range defines a minimum and maximum temperature, which the user can set in the thermostat. We can’t set lower temperature than minimum temperature and we can’t set higher temperature than maximum temperature for the range.

GUARD function:

GUARD function protects actuating elements (valve, pump, fan) from damage. If this function is activated, the thermostat once every two weeks change for a while the output state, even if it isn’t required. It prevents damage of actuating elements.

Software version:

In response to suggestions and opinions our customers, we try to increase systematically functionality of thermostats, so from time to time may appear newer software version.

Keyboard lock:

To protect thermostat from unwanted change settings, you can lock thermostat keyboard.

When keyboard lock is activated, on display is visible a padlock symbol and keyboard doesn’t respond to pressing keys.

Work scheduler:

In automatic mode we can set a work scheduler. It means setting suitable temperature at concrete hour.

With scheduler you can set lower temperature (economic temperature) in periods when e.g. building/room is not used or in nocturnal periods, and higher temperature (comfortable temperature) when building/room is used.

You can program four time segments each day of the week, which were symbolically presented on display:


A temperature symbol is visible together with the time segment symbol to know what type of temperature the time range concerns:


  • ATTENTION! These symbols are displayed only when the thermostat is set in work mode with two different values of temperature (comfortable and economic - setting SC with value 2).
  • If thermostat works in mode with individual value of temperature for each time segment (with four different values - setting SC with value 4), these symbols are not visible.
  • After programming all four time segments the thermostat returns to standard displaying mode.
  • The fourth time segment lasts until the beginning of the first time segment the next day (e.g. from 9:00 p.m. on Monday to 7:00 a.m. on Tuesday).
  • If there is no need to use all four time segments, you can set short time segments for example:
  • 1. 7:00 a.m.
  • 2. 7:01 a.m.
  • 2. 7:02 a.m.
  • 2. 15:00 a.m.
  • Comfortable temperature (or economic) in one day can be different than analogical temperature in other day.
  • ATTENTION! If you work with two different values of temperature (comfortable and economic) and for the time segment number 3 we will program different value than for the time segment number 1 (both of these time segments concern comfortable temperature), to the time segment number 1 will be automatically assigned the same value as to the time segment number 3. Analogically is witch the economic temperature and with time segments number 2 and 4.

Manual mode:

In manual mode the thermostat constantly keeps desired temperature (without work timetable).

  • If thermostat works in manual mode, on display is visible hand symbol and time segment symbol is not visible.
  • Thermostat is in the manual mode until user doesn’t change it to automatic mode.

Semi-automatic mode:

In semi-automatic mode is manual correction of desired temperature in current time segment. After the end of the current time segment, thermostat returns to the automatic mode and works with the timetable.

  • You can move to semi-automatic mode only from automatic mode.

When thermostat is in the semi-automatic mode, on display is inscription ‚override’. Symbol of the current time segment dissappears.

Holiday mode:

In holiday mode the thermostat constantly keeps desired holiday temperature.

  • If thermostat works in holiday mode, on display is visible suitcase symbol.

State of working:

When the thermostat is working, on display is visible a flame symbol.

Additionally, bar ratio symbolically presents difference between prevailing temperature (indicated temperature) and desired temperature (it shows how much heat is missing).


On display may appear symbols that signify::

  • LO - temperature is lower than -20 ºC.
  • HI - temperature is higher than 140 ºC.
  • ERR - temperature sensor is not connected or is damaged.
  • In cases above, for safety, actuating devices are turned off (phase is given on clamp OFF).
