BITERMO+ is a microclimate controller that controls work of fans and heaters depending on temperature and time (function of periodical ventilation). It has got two built-in control sections: the first works as ventilating and the second one works as ventilating or heating. Both sections are of the ‘ON/OFF’ type with a voltage-free output (relay contacts). It has got a large, easy to read display that allows to view messages. The easy and functional keypad guarantees entering settings and monitoring parameters very comfortably.

Temperature measurement is made by means of a digital temperature sensor.

The controller has got one relay alarm output and it indicates alarms e.g. when the set temperature thresholds are exceeded (temperature is too low or too high), in case of power supply failure, temperature measurement line damage etc.

Wiring diagram of the BITERMO+ controller with sensors and modules control:

Characteristics: 

• temperature measurement is made by digital sensors, the possibility of connection of up to 4 sensors TEMP-201, one sensor is included in the set,

• two built-in ‘ON/OFF’ sections with a relay output, voltage-free (NO and C contacts of a relay, load current up to 3A)

• relay alarm output (NO, NC i COM), 24 V, 200 mA,

• large, easy to read LCD display with messages in Polish.

 Functions:

• choice of the mode of operation of Section 2 (ventilation/heating),

• change of the stage of section operation and thermal alarms by means of one parameter: preset temperature,

• periodical ventilation: setting the cycle duration and choice of outputs,

• time of control response adjusted by means of settings,

• alarm function i.a . in case of exceeding set thresholds of temperature (upper and lower threshold), failure of the control process, power supply failure, temperature measurement line damage,

• the possibility of declaring the sensor of outside temperature (i.a. in order to correct an alarm threshold or when temperature is too high).
