Solar collector control

This solar collector control is the perfect solution for a normal solar collector system, it monitors the temperature of the collector and the tank in two places, and starts the pump if necessary.
It can also switch on electric auxiliary heating, an additional magnetic valve and the circulating hot water circulation.
The control is pre-programmed, personalization is not complicated.
If you still want professional equipment and programming, we can to recommend a contractor who Bp. It also goes to homes within a 100 km radius.

The advantage is that the control is a separate unit from the small-sized wall-mounted operator, which can thus be placed in a cultured way in the apartment.
