Circulation pump
: Solar heat regulator
The SH-E01 regulator is used for controlling utility water installations
consisting of a solar collector circuit and a hot water tank, where the
utility water is heated by solar energy.
The solar heat circuit circulation pump is controlled by the diff erential
temperature between the solar collector and the tank bottom.
If the diff erential temperature is higher than the preset start-up
temperature diff erential, the circulation pump will run.
To avoid unnecessary pump operation the temperature of the solar
collector has to be higher than 15°C before the pump starts operating.
The pump will run until the temperature diff erential is below 2°C.
