109: 4-pipe setpoint
WCS: activation point, cooling mode
WHS: activation point, heating mode
Note: the Boost function (
120
negative) is not available in 4-pipe
mode.
It is possible to display the operating setpoint by configuring the parameter
193
or
194
to 6. In this case, in heating mode, the
value corresponding to WHS is displayed, in cooling mode the value corresponding to WCS is displayed.
If no contacts are configured in “non-occupied/holiday” or “energy saving / boost” mode, and if the operating mode has
been set manually with timer periods (
Mod
=
tiMb
) and the timer period function
199
=0 (see “4. Quick access parameter setting”
page 8 ), then regulation is controlled within the timer periods with the base setpoints. In this case, “display C” (see “3.
Display, keypad and icons” page 7 ) shows the active timer period. Outside of the timer period, economy/boost mode is
active.
Otherwise, the contact or sensor status configured in “non-occupied/holiday” or “economy/boost” mode has priority and the
timer periods are not considered ( AH-xxCSx1 models).
If none of the contacts or sensors are configured in “non-occupied/holiday” or “economy/boost” mode and if operating mode
is in holiday mode (manually configured using quick access parameters → see “MODE button functionality” page 10 ),
then regulation is controlled with the holiday mode. Otherwise the contact or sensor status configured in the “non-occupied/
holiday” or “economy/boost” mode has priority over the manual configuration.
When timer extension mode is activated manually, it takes priority over energy saving / boost, holiday (see “28. Timer extension
or forced presence modes” page 109 ) and the timer period modes ( AHU-xxCSx1 models).
