EVK253 is a digital thermostat able to control compressor, defrost (by temperature-time) and evaporator fan.
The instrument is provided with three measure inputs both for PTC and NTC probes (cabinet probe, evaporator probe and condenser probe).
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.
Through the condenser probe it is possible to interact on the compressor activity if the working conditions had to be outside the safety limits.
Two communication ports (available by request) allow the communication with supervision systems (via TTL, with MODBUS communication protocol) or with the programming key EVKEY (the first one) and with the remote display EVT100 (the second one, not available in the models with power supply 230 Vac and 115 Vac).
EVK253 frontal size is 75 x 33.5 mm (W x H) and has been studied for panel mounting.
