Electronic controller REC25 for electric heating
The controller REC25 is intended to be used for electric heating control by PID algorithm. Operation is managed in accordance with set and measured temperatures. If measured temperature is lower than set one, controller gradually changes the pulse and pause time of heater's power supply voltage in order to get precise value of set temperature. The REC25 has 4 relay outputs for extra load control, if the heater has more than 1 step.
