    Combined mode 2: a solar collector, a boiler and an electrical heater restricted by a timer on this mode the water will be heated by all the heat sources connected to the water heater. If the temperature in the boiler is higher than that in the water heater with dif temp2 degrees, the circulation pu...

    Heating up by a boiler on this mode the water is heated only by the boiler installation. If the temperature in the boiler is higher with dif temp2 degrees, the boiler's circulation pump turns on and the heat from the boiler goes to the water heater. When the pump works it is visualized on the screen...

    Doesn't shine, the solar collector can only cool the water running through it and therefore the water heater, as well. The pump works until the temperature in the water heater goes below 30 degrees or until the temperature of the collector is only 5 degrees lower that the temperature in the water he...
