The installation unit TRW230-100.14 for refrigerating chambers and cooling cells unites control and power section in a complex and at the same time optically fastidious way. This extremely compact control ranks among the classics of its kind and proves its high functionality until today. That way, the cooling regulation contains all functions and components, in order to control compressors with electrical power of up to 0.8kW at 230V directly. The control has a 2-pole main switch as well as three potential-afflicted relays for a compressor, a ventilator and a defroster.
Together with the separate clamps for N and PE, this permits a fast and easy assembly without any additional wiring. An potential-afflicted alarm relay and two analogue inputs for temperature sensors make part of the standard equipment. The digital switching input for the external alarm switch is potential-afflicted and switched in series to the compressor relay. This provides, for instance, the possibility to supervise the switching status of a pilot switch to influence the regulation, and additionally to release an alarm.
The delivery programme includes two PTC temperature sensors with a cable length of 4 meters each.
