CS-77c control unit for 2 independent pumps (boiler and underfloor heating)

Determination

The CS-77C model controls two pumps (consumers) independently.

Working principle of the central heating pump

The task of the controller is to start the pump when the temperature exceeds the desired value and to turn it off when the boiler cools down (due to extinction). This prevents unnecessary work of the pump, thereby saving electricity (the savings, depending on how the boiler is used, can be as high as 60%) and extending the life of the pump.

Working principle of the pump II

Thanks to the device we have the opportunity to regulate the temperatures when the pump is started up and switched off. The pump turns on when the user-set start-up temperature (O) is exceeded and it turns off when the set shutdown temperature is exceeded (U)
