FK 216A is a digital thermostat able to control compressor, defrost (by temperature-time) and evaporator fan; a fourth relay (which status can be changed through a button at the front) allows to manage a further load (cabinet light, demisting resistances, etc.).
The instrument can work with PTC or NTC probes.
Some configuration parameters allow to protect the compressor against overloads, to manage the defrost according to the requirments, to set the evaporator fan operation, etc.
The RTC (Real Time Clock) allows to plan up to 6 daily defrost cycles and to program automatic changes of the working temperature (Energy Saving).
The instrument is provided with a serial port (to interface it with supervision systems).
FK 216A frontal size is 75 x 33.5 mm (W x H) and has been studied for panel mounting.
