Terminal details of wiring
1. Floor heating valve:
When floor heating side work, 3-way valve coil get electricity. The terminal supply
220V/1ph voltage.
2. Hot water valve:
When hot water side work, 3-way valve coil loss electricity. The terminal supply
220V/1ph voltage.
3. Cycle water pump:
Rated current should be less than 12A, and power supply is 220V/1ph, if the
current is larger than 12A, should through AC contactor, like below drawing.
4. Hot water electric heater:
Max carrying current is 6A. 220V/50Hz/1ph. If electric heater input power is
＞
1KW,
should though a AC contact to connect to the terminal.
