Control

There are several options offered with these heaters batteries which enable differing methods and complexity of control;

-  MTEML /-MQEML / -MTUL / -MQUL, for One or Two Sensors. Duct heaters with integrated temperature regulator, for room or duct sensors. Can also be connected to a main sensor in the
room and to a min./max. sensor in the inlet air.

-  MQXL / -MTXL, for 0...10 V Control Signal Duct heaters with integrated regulator for external 0...10 V control signal.

-  MQYL / -MTYL, for 2...10 V Control Signal.

-  MQCL / -MTCL, for 4...20 mA Control Signal.

-  M, not internal control;  instead for connection to external controls and regulator.

The duct heaters may be equipped with Modbus communication.
