External room thermostat
When the reheat temperature is reached, the further heat up of the domestic hot water tank will be decided
by the external room thermostat thermo conditions and running timers which are programmed by the
installer.
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.
