MAINTENANCE RANGE
The MAINTENANCE RANGE is the range beyond which the programmable thermostat turns on
the heating/cooling. The range is centred on the SET TEMPERATURE. You can make it smaller or
greater, depending on how the room’s temperature changes (size of the room and influences from
outside).
In WINTER “
” mode, the programmable thermostat turns on the heating system when the
temperature measured in the room is :
SET TEMPERATURE - 1/2 OF MAINTENANCE RANGE
The heating system is turned off when the measured temperature is:
SET TEMPE 1/2 OF MAINTENANCE RANGE
Conversely, in SUMMER “ ” mode, the cooling and/or air conditioning system is turned on
when the measured temperature is:
SET TEMPE 1/2 OF MAINTENANCE RANGE
The cooling and/or air conditioning system is therefore turned off when the measured temperature
is:
SET TEMPERATURE - 1/2 OF MAINTENANCE RANGE
The MAINTENANCE RANGE is pre-set in the programmable thermostat to 0.4°C in WINTER “ ”
mode and to 0.8°C in SUMMER “ ” mode.
Therefore, for example:
Mode: WINTER “
”.
SET TEMPERATURE: 20.0°C
MAINTENANCE RANGE: 0.4°C
MEASURED TEMPERATURE:
20.0 - 0.2°C = 19.8°C HEATING SYSTEM ON
MEASURED TEMPERATURE:
20.0 + 0.2°C = 20.2°C HEATING SYSTEM OFF
To change the MAINTENANCE RANGE (dt), wake the unit from STAND-BY to display the Home
Screen by simply touching the display. From the Home Screen , press the TEMPERATURE area
on the display for 2 seconds (Fig. 72). " dt ” will be shown in the upper right area of the display and
the value of the dt currently set for the related program will be shown in the upper left area.
You can then adjust the dt between 0.2°C and 2°C using the “
+C
” or “
-C
” buttons (Fig. 73).
To exit the function, press the maintenance range or wait 12 seconds.
