
[7-00] Bottom plate heater option
An optional bottom plate heater can be installed in your outdoor unit. In case an ERRQ* outdoor unit
(special model with freeze-up countermeasures) is installed, the unit will have the bottom plate heater
already standard installed.
If the bottom plate heater is installed, its operation must be enabled by field setting. Default [7-00] = 0
which means no bottom plate heater is installed. Set [7-00] to 1 if the bottom plate heater is installed.

[7-02] Select multiple set point pattern A or B

Multi set point control according pattern A
During normal operation, domestic water heating and space heating modes are separated and
activated intermittent to fulfil a simultaneous request. Therefor multiple set point pattern A can be
configured to allow simultaneous domestic water and space heating without intermission.

Multi set point control according pattern B
The basic setup of multiple set point pattern B is the same as a normal classic design, so AGAIN
no domestic water heating and space heating is possible simultaneously. Multiple set point pattern
B is focussed on space heating operation and allows using multiple water set points in
combination with the remote controller or external room thermostat. The configuration of pattern
B allows space heating set points and the domestic hot water set point.
