Fill the heating system at a low water pressure (approx. 1 bar).
During filling, open the three-way changeover valve several times
manually if the system includes a gas-fired boiler. On gas-fired
condensing boilers, open the air vent valve in the DHW cylinder
flow. Check whether the lid on the quick-action air vent valve is
loose. Briefly start up the boiler (circulation pump).
Demonstrate operation to user, including operation of temperature
and relief valve and what to do if it operates.
Give this manual to the user to retain for future reference and make
the customer aware that periodic checks of the equipment are
essential for safety.
Adjust the DHW cylinder temperature on the Wolf gas-fired boiler
between 15 - 70 °C using the cylinder thermostat. For reasons of
economy, thermostat setting 7 (approx. 60 °C) is recommended. For
regular pasturisation, a DHW cylinder thermostat setting of 70 °C
(position 9) may be selected. This setting is only intended for brief
and supervised operation.
In hard water areas we recommend thermostat setting 7 (approx.
60°C) to prolong element life.
The DHW cylinder temperature can be read off at the display if a Wolf
gas-fired boiler is connected to digital control accessories DRT, DWT
or DWTM, (see operating instructions of the respective control unit).
When using digital control accessories DRT, DWT or DWTM for Wolf
gas-fired boilers, the cylinder loading time for the CSW-120 DHW
cylinder may be selected via a two-channel time switch CSW-120.
The loading times can be freely selected via the day/week program.
Programming the cylinder loading times is detailed in the control unit
operating instructions.
