Electronic controller REC50 for electric heating
The controller REC50 is intended to be used for electric heating control by a PID algorithm. Operation is managed in accordance with set and measured temperatures. If the measured temperature is lower than the set one, the controller gradually changes the pulse and pause time of the heater's power supply voltage in order to get a precise value of the set temperature. The REC50 has 4 relay outputs for extra load control if the heater has more than 1 step.
Working mode:
- With one sensor (supply air temperature control).
- With two sensors (the regulating extract/room air temperature according to the setpoint supply air temperature limiting).
- With an external control signal 0-10VDC.
