Recharging Bedrock/Ground
If a liquid/water heat pump is connected, a 3-way valve can be installed on
the solar circuit and connected to the brine circuit (the coil in the bedrock
or the ground heat coil). The solar panel temperature should be factory set
at 60°C warmer than the brine temperature for charging to start. When the
difference between the temperature in the solar panel and the brine circuit
falls to 30°C, charging is stopped. If the brine circuit becomes warmer than
the factory-set value of 18°C, recharging will also be interrupted, as the
temperature then becomes too high for the heat pump to work.
Safety measures for the collector/solar system are available.
Also refer to the "Protection collector" section in the "Detailed Menu
Descriptions" chapter (Installer/Settings/Solar Panels/Protection
Collector).
Also refer to the "Winter mode" section in the "Detailed Menu
Descriptions" chapter (Installer/Settings/Solar Panels/Winter Mode).
Schematic diagram only the installer adds expansion vessels, safety valves, etc., and sizes the system.
