Temperature Controller

Temperature display, temperature controlling(refrigeration/heat mode can be set),compressor start delay protection, temperature sensor error alarm, one external alarm input, password, C/F unit change. Technique Index1,Temperature display range: -50 150°C(The resolution is 0.1°C) -58 302°F(The resolution is 0.1°F)2,Power supply: AC 220V±10% or AC 380V±10% 50Hz (Refer to the wiring diagram)3,Operating environment: temperature -10°C 50°C, humidity≤85%4,Relay contact capability: 20A/250VAC (pure resistive load)5,Temperature sensor: NTC R25=5kΩ, B (25/50) =3470KOperating Guide1, Meaning of the index lights on the panelIndex lightNameLightFlashTemp settingIn the state of temp setting-RefrigerationRefrigeratingReady to refrigerate, in the state of compressor start delay protectionHeatHeatingReady to heat, in the state of compressor start delay protection------Alarm-Alarm state2,Meaning of the LED display The LED usually shows temperature, if it shows “SHr”, it means the temperature sensor is short, and “OPE” means the temperature sensor is open. The temperature and the alarm code (Axx) will show alternately when in the alarm state. The code is showing below:CodeMeaningExplanationA11External alarmAlarm from external alarm signal, refer to the internal parameter code “F50” A21Temperature sensor errorOpen or short(showing “OPE” or “SHr”)
