Electronic controller REC25 4xDO for electric heating

Electronic controller REC25 4xDO for electric heating

The controller REC25  4xDO 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 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 REC25  4xDO 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.
