11. Pre-heat function
When changing from Economy to Comfort temperature in AUTO mode, your thermostat will anticipate the rise in
temperature so that it reaches the right temperature at the scheduled time.
Example (see opposite): 6:30 am, Economy period, currently pre-heating to reach the temperature of 20°C at 8:00
am.
The pre-heating function’s speed and accuracy is based on the heater type used and its heating inertia..
Pre-heat in progress is shown by the symbol ashing and the
Comfort signal.
11.1 Changing baeries
• The symbol appears.
You have approximately 1 month to replace them (two 1.5 V alkaline
baeries, either LR03 or AAA).
WARNING: make sure you insert the baeries facing the right way and
that they are the right type (no lithium baeries).
You have about 30 seconds to change the baeries before the time
seing is reset (in this case, reset the day and time seing).
The conguration and programming are saved in case the power is o
for a long time.
• The display shows dEF21.
You have passed the 1 month limit for low baeries. You
MUST change the baeries in your device.
11.2 Frequently Asked Questions (FAQ)
• The thermostat is on despite the programme not calling for it.
You must have turned on the pre-heat function. If so, then it is normal for your thermostat to anticipate the
temperature rise and it has started pre-heating to get to the Comfort temperature at the desired time
(see § Pre-heat function).
• The thermostat turns o though the requested temperature has not yet been reached.
Your thermostat uses a kind of control that means you can anticipate the inertia in temperature variations in order
to calculate energy needs as accurately as possible and provide maximum comfort.
Conversely, to allow for a drop in temperature, the heater may turn on once the desired temperature has been
reached.
