Rean RCR305-230 Dual Sensor Panel-Mount Cold Room Digital Thermostat (NTC Sensor Included)

The Rean RCR305-230 panel-mount cold room digital thermostat is developed to precisely monitor and control temperature and operating conditions in cold rooms and industrial refrigeration systems. Thanks to NTC sensor support, it tracks room and evaporator temperatures separately.

With the 3 NTC sensor inputs on the device, room temperature, evaporator temperature and an optional third sensor can be used. Thanks to its wide LED display and status indicators, the current operating status can be easily monitored.

5 relay outputs allow cooling, defrost, fan, lighting and auxiliary (AUX) control functions to be managed from a single device. The lighting and AUX outputs can also be controlled manually with the keypad on the device.

Compressor protection parameters, sensor calibration values and temperature setpoint limits are user adjustable. It provides precise control with a 0.1°C temperature reading resolution.
