9.4.2 Away temperature
This menu, via
and
, lets you increase/decrease the value of the away temperature
.
The away temperature, preset by the user, is an intermediate temperature geared to obtain sub-
stantial energy savings during periods when the user is away.
The away temperature differs depending on whether you are in the heating or air-conditioning
mode.
9.4.3 Antifreeze temperature
This menu, via
and
, lets you increase/decrease the value of the antifreeze tem-
perature
.
Antifreeze mode is used to set a minimum temperature level to avoid damage to the pipework or
keep the room temperature from falling below a safety level (see par. 7.5).
9.4.4 Nighttime reduction thermal delta
This menu, via
and
, lets you set the difference between the Nighttime reduction
temperature and Tcomfort temperature (or the temperature set in Manual mode).
The hysteresis is an increase/decrease in temperature that is applied to the Manual setting (when
nighttime reduction is activated by the display) or to Tcomfort (when nighttime reduction is acti-
vated by the multi-function input); the thermal delta value is identical both in heating mode and in
air-conditioning mode with the only difference being that in the former case it causes a decrease
in the set point while in the latter one it determines an increase.
The nighttime reduction mode can be activated either locally or via the multi-function input (if
configured appropriately).
9.4.5 User settable thermal delta
This menu, via
and
, lets you set the range of values within which the user can adjust
the temperature when the menus are inhibited following remote activation or entering the PIN.
When the thermostat is turned on remotely (via the multi-function input when suitably configured),
the control temperature is fixed and therefore cannot be changed; with
not zero instead,
the user can modify the temperature within a certain range.
For example: multi-function input set as remote activation, T. comfort set at 20.0°C. Setting the
thermal delta to 0.8°C allows the user to change the temperature setting from 19.2°C (20.0°C -
0.8°C) to 20.8 (20.0°C + 0.8°C).
