DHW does not heat up.
radiators do not heat
up.
The central pump is not
working.
Check whether the cen-
tral pump is running.
The heating system is
not working.
Check whether the
heating system is free
from faults.
if you cannot remedy the fault, contact your qualified contrac-
tor. To facilitate and speed up your request, provide the num-
ber from the type plate (000000-0000-000000).

6. Safety
Only a qualified contractor should carry out installation, com-
missioning, maintenance and repair of the appliance.
6.1 General safety instructions
We guarantee trouble-free function and operational reliability
only if original accessories and spare parts intended for the
appliance are used.
6.2 Instructions, standards and regulations
Note
Observe all applicable national and regional regula-
tions and instructions.
7. Appliance description
Domestic hot water
For DHW heating, cold water flows to the plate heat exchanger.
The "Thermo Fluid System" temperature controller detects the
DHW demand. Some of the heating water from the heating
water flow is channelled over the heat exchanger to heat the
DHW to the required temperature. DHW from the cold water
connection is channelled through the heat exchanger and
heated as required. DHW flows from the heat exchanger to
the "DHW outlet".
The temperature level of the DHW can be further increased
by switching on the integral instantaneous water heater. This
enables outlet temperatures of up to 60 °C.
a "Cold water outlet" supplies the draw-off points from a cold
water distributor inside the appliance.
Room heating, e.g. radiators
Heating water from the heat generator is distributed by the
appliance to the heating circuits via the "Heat source flow" and
the dirt filter. The common return to the supply side is through
the "Heat source return" with a differential pressure controller.
Heating water from the "Heat source flow" is supplied directly
via the "Heating flow" to the heating circuit without mixer, e.g.
radiators.
The flow temperature can be reduced to a lower temperature
level (e.g. for underfloor heating systems) via an optional heat-
ing circuit with mixer.
an actuator and room temperature controller available as ac-
cessories can be used to centrally interrupt the heating circuit
supply once the required room temperature is reached.
8. PROFI SELECT modular system
The PrOFi SElECT modular system consists of 4 components:
- Base station
- Output modules
- installation options
- accessories
Order code
The order code consists of the base station designation, fol-
lowed by an "E" and the internal code for the installation op-
tions.
Example: Order code "WSP2DUOE-7.1"
