Regulator for solar water heaters

Differential controller specially designed for water heaters to solar power, checks the temperature difference between the collector (T2) and the bottom of the flask (T1).
When the temperature T1-T2 is above the setpoint Delta T, the device activates the solar circulation pump (K1).
If the temperature of the water tank (T3) falls below the setpoint St2, the device activates the boiler circulating pump (relay K2) for minimizing the solar system.
For free cooling function (refreshment facilities with cold outside air), simply position the probe 1 to the outside, and the probe 2 within the premises with some work.
The unit is equipped with frost protection systems and overheating.
It is possible to switch on a forced march to the K1 start setting sun.
