Remote controller room temperature control
When the reheat temperature is reached, the further heat up till storage temperature of the domestic hot
water tank will be decided by the remote controller room thermostat in order to prevent that the room
temperature drops too much.
1. Reheat operation
When requesting space heating and domestic water heating (reheat) at the same time. This involves
that the minimum reheat temperature is reached (setting [b-00]) during space heating operation. The
3-way valve will switch over to the domestic hot water side. The domestic water will be heated till
maximum reheat temperature (setting [b-01]). The 3-way valve will switch back to original position,
then space heating will start again.
During the reheat operation, the system does not take care about the room temperature. This means
that during simultaneous demand, the reheat operation has priority over the room temperature.
