(Default value 24°C)
The logo will blink and the number of hours /days left is
displayed until the end of the peri od.
If you wa nt to stop t he Ti mer functio n be fore the end, set
the duration peri od to “no ” wit h (-) key or use t he navigation

3.8. Reversible mode
The r eversible mode all ows you to c hoose the worki ng mo de
for your installation.
By pressing on (-) or (+) keys, the selected worki ng mode
blinks and can be modifi ed. The user can then choose:
- Hot : the installati on operates in heating mode (winter)
- CLd : the installati on operates in cooling mode (summer).
Warning: t his menu is availabl e if user ac tivates parameter 21
in Installer’s advanced Menu (refer to c hapter 8)
During t his sel ection, t he status LED will be red col or i f heating
is selected or green color i f cooling is selected.
By pressing (OK) key, you vali date you sel ection. By pressing
(◄) or (►) key or the ( ) key , yo u come back to the c urrent
working mode of the thermostat.
Remarks:
- This me nu is only available i f the parameter “21” has bee n set
to “REv” (refer to chapter 8)
- This mode is not avai lable if thermostat is linked wi th a central
(BT-CT02).
4. Special functions
4.1. Key lock
Use this function to prevent all change of yo ur setti ngs (I n a
child room, public area…)
- To activate the Key lock fun ctio n, fi rst press maintain the
escape key ( ) and t hen press si multaneously on t he edi tion
key ( ) .
- The “ ” logo will be displayed on the scree n.
Repeat the same procedure to unlock t he key board.
4.2. Open window function
This functi on i s abl e to stop heating if thermostat detects a n
unusual decrease of temperat ure (open window).
Principle:
If t he di splayed temperature (internal or ambi ent se nsor)
decreases by 3°C or more d uring a 5 minutes period (or less),
the t hermostat stops heating f or 15 minutes. If the temperature
continues decreasing, it co ntinues to stop.
During this stop, the room temperat ure will blink.
Return to normal mode:
The t hermostat returns automatical ly to normal mode after t he
stop period.
The f unction can be overri dden by pressing the (OK) butto n
during the stop heating phase.
The bl inking temperature should stop to indicate t he e nd of the
detection.
Special cases:
- This function doesn't work i f thermostat is in Floor regulati on
- This functio n does n't wor k if thermostat is i n OFF or
Antifreeze Mode
- If temperat ure i s less than 10°C, t hermostat will regulates at
10°C during the stop p hase (refer to chapter 5, parameter 06)
- This function doesn’t work i n Cooling mode
4.3. Humidity measurement
(
*
)
Thermostats measure the hu midi ty in the air. This measure
allows:
- To regulate the humidity in the ai r (refer to parameter 34 i n
chapter 8)
- To protec t your system agai nst condensati on (r efer to
parameter 35 in chapter 8).
4.4. Visualization
With th is function , you can quickly vi ew the c urrent
temperatures of t he di fferent sensors connected on yo ur
thermostat (floor, remote, e xternal). To do so, o n the main
screen, press several ti mes on the escape key ( ) . This “scroll
function” is only avail able on the main screen:
You will see in the order of eac h press:
1/ the setting temperature fol lowed by the thermostat
2/ the ambient temperature
3/ if the external sensor is co nnected: the outside temperat ure
4/ the humidity percentage (*)
Remarks :
- refer to chapter 1.2 for icon mea nings
- If Parameter “Sen ” i s set on “Air ” (refer to c hapter 8), the
remote sensor will be used as an external sensor.
5. Parameter’s menu
Your t hermostat has a parameter’s menu. To enter i n this
menu, press a nd maintain the e diti on key ( ) during 5sec.
Then parameter me nu will appear and first parameter screen
will be displayed
Now you can select a parameter which must be adjusted wi th
the navigati on keys ( ◄) or (►) , o nce the parameter c hosen,
toggle the val ue with the (OK) key, modify it wi th (-) or (+) and
confirm your adjustment with (OK) .
To leave the parameter menu, choose the parameter « End »
and press (OK
)
or Return key ( ).

Calibration of the internal probe
The cali bration must be do ne after 1 day worki ng with
the same setting temperature in accordance with the
following descripti on:
Put a thermometer i n t he r oom at 1.5M di stance from
the floor (li ke the thermostat) and check the real
temperature in the room after 1 hour.
When you enter on the cali bration parameter “no ” i s
displayed on t he right to indicate no calibrati on has
made.
To enter the value shown o n the thermometer, use t he
(-) or (+) keys to enter the real value. Then, press (Ok)
to confirm.
The message “Yes ” should be di splayed; the val ue will
be stored in the internal memory.
If you need to erase a calibration press on t he escap e
key ( ) .
The old value will be erased and t he message “no ” will
be displayed.
* Pay attention:
Only the heating element dri ven by the thermostat must
be used during the complete step of t he calibrati on.

This automatic control system works in the following
way:
When yo u start y our t hermostat f or the first time, i t will
measure t he time taken by your i nstallati on to reac h the
set temperature. The thermostat wil l re-measure this
time at each program c hange to comp ensate e xternal
