Electronic controller REC 16, REC 16MB for electric heating

The controllers REC.. are intended to be used for electrical heating control by PID algorithm. Operating is managed in accordance with set and measured temperatures. If the measured temperature is lower than set one, controllers gradually change the pulse and pause time of the heater's power supply voltage in order to get the precise value of set temperature. The controllers can work with an internal or external temperature sensor or with both at one time when heating control is carried out with temperature limitation of the supply air and the room temperature control according to the set temperature. Controlled phase current is switched at zero angle to avoid radio interference. The controllers can be used for single-phase or two-phase power supply, it is not suitable for a three-phase power supply. Controllers REC16MB are intended to be connected to building management system (BMS) via RS485 mode by MODBUS protocol.
