Heat Pump water heater controller

Heat Pump Water Heater Controller The controller is the special controller for heat pump, it has three sensors (water temperature sensor, evaporator temperature sensor, exhaust temperature sensor), three output (compressor, valve, fan), two input alarm signal (high pressure, low pressure). Main Function 1,Temperature display and controlling 2,Compressor start delay protection 3,Auto defrosting controlling 4,Exhaust temperature protection 5,High pressure and low pressure protection 6,Real time clock, can set mode 7,On-off state memory when the power is off 8,Alarm code display 9,Direction of valve can be set, password, and so on Main Technique Index 1,Temperature display range: -50 150°C2,Temperature set range: 0 100°C(can restrict setting range)3,Power supply: AC 220V±10%4,Operating environment: temperature -10°C 50°C, humidity≤85%5,Relay contact capability: compressor 20A/250VAC, others 2A/250VAC (pure resistive load)6,Temperature sensor: NTC R25=5kΩ, B (25/50) =3470K 1,Temperature display range: -50 150°C2,Temperature set range: 0 100°C(can restrict setting range)3,Power supply: AC 220V±10%4,Operating environment: temperature -10°C 50°C, humidity≤85%5,Relay contact capability: compressor 20A/250VAC, others 2A/250VAC (pure resistive load)6,Temperature sensor: NTC R25=5kΩ, B (25/50) =3470K
