Main functions and technical indicators
The controller is a special controller for heat pump water heater, with three temperature sensors (water temperature, external temperature, coil temperature), three-way control output (compressor, defrosting, fan), one alarm signal input (for high and low pressure protection) Wait). The main functions are as follows:
1. Solar water heating function (default is none, choose this model to buy another solar sensor line)
2, electric heating function
3, large LCD display function
4, timed on/off function, can be set to 1-24 hours on/off
5, power-down memory function, can remember the on/off status and modified heat pump operating parameters
6, all temperature sensor temperature real-time query function
7, all temperature and temperature sensor fault display function
8, compressor high / low pressure and water flow switch protection
9, winter one / two antifreeze protection
