Solar panels
1.6 Solar panels*
Solar panels can be connected to the buffer tank, DHW system and the
bedrock/ground source heating circuit via 3-way valves.
When the temperature rises and the temperature difference exceeds 7°C
(factory setting) between the solar panels and the DHW tank, the charge
pump starts and transfers the solar heat to the DHW system. The speed-
controlled pump controls the flow so that it always delivers a temperature of
at least 7°C higher. This means that if solar panel output rises, the charge
pump will increase the flow, and if solar panel output decreases, the charge
pump will reduce the flow. When the DHW tank temperature increases or the
solar panels drop in temperature and the temperature difference becomes
3°C (factory setting), the charging stops and does not start again until the
temperature is at least 7°C warmer than in the DHW tank.
If both the DHW tank and buffer tank are defined, the DHW tank is
prioritised. Charging first takes place to the DHW tank; once the set setpoint
has been reached, charging changes to the buffer tank. Charging continues
until a need for DHW arises or the set setpoint has been reached.
There are protective functions for the solar panels/the collector (refer to the
"Installer/Settings/Solar Panels/Protection Collector" menu).
Heat exchangers and pumps (G32) do not need to be installed to the solar
heating circuit if there is already an existing loop in the connected DHW/
heating tank.
