6.2.6 Connection of outside temperature sensor
The following modulating controllers can be connected:
The EMS bus connector can be labeled either "RC", "BUS"
or "EMS".
ÿ External 3-way valve at connection terminal :PW1
ÿ If several external safety devices such as e.g. B. TB1 and
condensate pump are connected, they must be connected
in series.
ÿ Connect the circulation pump to connection terminal ;PW2 (ÿ Fig. 24, [4]).

heating
[5] Mains cable to the following functional module
A switchable heating circuit pump can also be connected
instead of a circulation pump. This pump is switched off
when hot water is being prepared via the internal 3-way
valve and the unit's internal pump.
• Rules CR 100, CW 100
