STT: solar temp. sensor
EV: solar expansion vessel
FS: flow limiter with flow meter
HW: hot water outlet
The solar system must be connected to connections marked with »B« and »D« on scheme »10. Unit dimensions«.
Regulation of the solar system must be connected to a separate regulation system for regulating the solar
circulation pump. The temperature sensor for the water temperature can be inserted into the sleeve next to the
heat pump temperature sensor for the bottom temperature, which is located on the back side of the heat pump.
The maximum allowed temperature of water from the solar system must never exceed 85°C. This needs to be
considered when setting the parameters for the solar system. The maximum pressure of 0,5MPa must also never
be exceeded.
