English Manual
Description:
This listing includes: 1 Controller for Pressurized Solar and Hot Water System 220V.
Application:
Can be used in solar and hot water heating systems: one collector array, one reservoir, one water pump and an auxiliary heater.
Features:
Solar Loop Pump (R1) is turned on when switch-on temperature difference between collector array (T1) and storage tank (T2) is reached.
When the temperature difference between the collector array (T1) and the reservoir (T2) is lower than stop temperature difference (T off) or when the reservoir temperature (T3) reaches the pre-set maximum storage temperature, the solar circulation pump will work. (R1) will turn off.
Auxiliary Boiler Standby Heater: Within the standby heating setting time, when the temperature T3 is lower than the open temperature, the standby heating circulation pump (H1) will activate when the T3 reaches closed temperature when heating. stopped.
