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
Function
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.
