3.10 Operation of the DHW system
The key enables you to switch the DHW (domestic hot
water) mode on and off. The selection is shown by a
bar, which appears under the corresponding symbol.
Manual activation: Hold down the DHW key for 3
seconds (Switch from "reduced" to "nominal" until the
next time the DHW timer switches over).
To ensure a DHW setting over 45°C, the electrical
back-up heating or the boiler must be left on.
In order to optimise operation of the DHW, it is possible to:
-Program the timer settings (parameters 560 to 576),
-Adjust the nominal temperature set point (parameter 1610),
-Adjust the reduced temperature set point (parameter 1612).
Press the info key to obtain the details on the DHW
(temperature setting operation).
3.11 Selecting cooling mode
If the installation is fitted with the cooling kit.
The key activates and deactivates cooling mode.
3.12 Pilot-wire
(if Regulation extension kit AVS 55)
It's possible to order up to 15 electric heaters via output
"pilot wire".
The "pilot wire" handles only the hourly operation of
radiators (comfort mode / reduced mode commutation
and Frost protection mode).
The comfort temperature setting should be done directly
on the radiator(s). The "pilot wire" does not handle
the temperature of the radiators. Refer to the manual
supplied with the radiator(s).
Put the radiators on "
PROG" mode or "AUTO" mode for
piloting by the regulation board.
The difference between the comfort temperature and
the reduced temperature is from 3,5 °C.
Frost protection temperature is preset at 8°C
(parameter 1014).
In the absence of signal (HP on "Off"), radiators
operating in comfort mode
3.13 Telephone modem
(if Regulation extension kit AVS 55)
It is possible to select the freeze protection
mode on the heat pump using a modem contact
(e.g. Siemens TEL 110).
The telephone command switches the current heat
pump settings to freeze protection mode. In accordance
with the setting, any temperature requests from the
heating circuits and the DHW are ignored.
The heat pump and/or the remote control must not be in
freeze protection mode.
