1、 Overview
This controller is applicable to single compressor (single phase), air-cooled, circulating heat pump hot water units. The controller is composed of mainboard, indoor operation wire controller and thermostat (optional). It is characterized by reliable performance, advanced func
2、 Main technical parameters
1. Service conditions
◇ Operating voltage: AC220V ± 10%, 50Hz ± 1Hz
◇ Operating ambient temperature: - 20~+75 ℃
◇ Storage temperature: - 30~+80 ℃
◇ Relative humidity: 0~95% RH
2. Temperature control accuracy: ± 1 ℃
3、 Main functions of controller
1. Heating and cooling operation
2. It can display the water tank temperature and the set temperature, and has the query function (it can query the coil temperature, ambient temperature, exhaust temperature, etc.)
3. Various parameters are automatically memorized after power failure, and the operation can be automatically restored after power on
4. The clock still runs after power failure, saving the trouble of readjustment every time power failure occurs
5. Peak load shifting power utilization function, which can realize two sections of timed power on/off within 24 hours
6. Setting and correction of various parameters
7. Electric auxiliary heating function
8. Automatic defrosting function
9. Forced defrosting function
10. Large touch key LCD display (full transparent LCD with white characters on blue background)
11. Perfect protection function
12. Fault code display and query (you can query the cause of the failure of the press not starting or stopping) and keyboard lock function
13. The water temperature is displayed in real time when the machine is turned on and off
14. Automatic control of electronic expansion valve
15. When there is no panel (or the panel is damaged), the system can automatically identify and start up to make hot water
