2 First Installation
This section will g uide you to se t up your t hermostat for t he first time.
2.1 Batteries installat ion
- Open th e two si de’s covers and in sert the 2 AA A Alk aline supplie d batteries (or remove
the small protection sti cker if the batteries are alread y installed in the c ompartm ent)
- Close the t wo side’s covers.
2.2 RF installation
Please have a look at the list of all receivers com patible with this thermos tat in Technic al
Caracteristics sec tion.
2.2.1 With recei vers
- Fi rst of all to co nfigure your th ermostat with the receiver, you mus t put your receiver in
RF init mo de. (refer to th e receiver leaflet, onl y the R F recei vers of t he same range are
compatibles)
- Press and maintain t he editi on ke y ( ) during 5s, then the parameter « INI » m ust be
displayed.
The thermostat will send now the r adio confi guration signal t o the receive r.
- After fe w seconds , the t hermostat and th e receiv er should exit by their self the RF i nit
mode, this is the n ormal procedure to confirm a c orrect pairin g.
- You can check the R F dista nce. Go to the r oom which must be regulated . Put your
thermostat on the final p osition (On the wall or tab le...), then p ut t he therm ostat i n
Comfort mode (setting temp erature p osition 3 7°C). Close the d oor and go to the receiver
to check if the new thermostat s tatus has received .
- Ret urn to the th ermostat and s witch it off. C heck on th e r eceiver again if it’s also
switched off.
If the RF signals were received c orrectly, adjust your setting tempe rature as you want.
If the R F signals weren’t received correctl y, check the inst allation (R eceiver position,
distance...) or resta rt the RF init rules to be su re.
Remark: T o mak e the installatio n easi er, it will be better to have the th ermostat near to
the receiv er d uring the configuration mode (a m inimal distance of 1 mete r m ust be
respected).
2.2.2 Case of central (BT-CT02)
The link is done with central (BT- CT02) .
2.3 Starting
The thermostat is n ow read y to work. Default working mo de is Comfort mo de
3 Working mode definition
Your thermostat has several different work ing modes to allow you t o adjust your unit
according to you r life habitudes.
To change the working mode, open the small center
cover to acces s to the navigation ke ys (◄) or (►) . Move
the frame cursor on the desired working mode and press
(OK) to enter in the chosen operati ng mode.
3.1 Manual mode C omfort
Manual work ing mode, the comfo rt setting tempe rature will be followed all t he time.
By pressing (- ) or (+) k eys, t he comfo rt setting tempe rature sta rts to blink and can be
adjusted.
Remark: Setpoi nt in Comfort mo de is used in
mode
3.2 Manual mode Reduced
Manual work ing mode, the reduc ed setting temperat ure will be follo wed all t he time.
By pressin g (-) or (+) k eys, the reduced s etting temperatu re sta rts to blink and can b e
adjusted.
Remarks:
- Setpoint in Re duced mode is us ed in
mode
- In cooling mode, Re duced m ode acts lik e the OFF mode ( system is stopp ed)
3.3 OFF mode
Use this mode if you need to s witch off your inst allation.
Be Careful: In this mode your installation c an freeze.
At any time, when displa y is off, pres s on the (Ok) ke y to displa y a fe w s econds the
current temperatu re and time.
Remark: To exit t he operatin g mode, u se the navigation k eys (◄) or ( ►) .
3.4 A nti-freeze mode
Use this mode if you want to pro tect your install ation against f reezing.
- The anti -freeze setti ng temperat ure is fix ed and can be ad justed in the parameter
menu number 06 ‘HG’ , refer to ch apter 5 (Default v alue 10°C ).
Remark: in cooling mode, Anti-freeze m ode acts lik e the OFF mode (installation is
stopped).
3.5 Timer mode
The T imer mode all ows you t o adjust, the t emperature for a speci al time. After this tim e,
thermostat will ret urn to older curre nt mode .
- You can first adjust, t he desired s etting temp erature w ith (-) or (+ ) , press (OK ) to
validate (Default val ue 24°C)
- In a second time, you can a djust the duration in hours “H” if below 2 4H, then in day “d ”
with (-) or (+) , pres s (OK) to start th e function.
The logo will blink and the number of hou rs /d ays left is displayed until the end of the
period.
If you want to st op the Timer f unction before the e nd, set the durati on period t o “no ”
with (-) key or us e the navigati on keys (◄) or (►) .
3.6 Reversible mode
The reversible m ode allows you to choose the working mode f or your install ation.
By pressing on (-) or ( +) k eys, the selected working mode blink s and can be m odified.
The user can ch oose:
- Hot : the installation o perates i n heating mod e (winter)
- CLd : the installati on operates i n coolin g mode (summ er).
During this sel ection, the status LED will be red col or if heati ng is selec ted or g reen color
if cooling is select ed.
By pressing ( OK) key, you validate you selection. B y pressi ng (◄) or (►) key or the
( ) key , you come back to th e current working mode of the t hermostat.
Remarks:
- This m enu is only availabl e if the parameter “ 21” h as bee n set to “RE v” ( refer to
chapter 8)
- This mode is not av ailable if therm ostat is li nked with a central (BT-CT0 2)
3.7 A UTO mode
This mode appears when if a central is link ed to your i nstallation. In this case, the zone
of the thermost at follows the pro gram created o n the Central (BT -CT02).
4 Special function
4.1 Keyboards lock F unction
Use this function to prevent all ch ange of your set tings (In a chil d room, public area…)
- T o activate th e Ke y lock function, fir st maintain the escape k ey ( ) pressed and press
simultaneousl y on the edition k ey ( ) .
- The “ ” logo will be displa yed on the sc reen.
Repeat the sam e procedure to u nlock the ke y board.
4.2 Open windo w function
This function is a ble to stop heating if thermostat d etects an unusu al decrea se of
temperature (open windo w).
Principle:
If the displayed tempe rature (internal or ambient sensor ) decreases b y 3°C or more
during a 5 minu tes period (or less), the thermostat stops heating fo r 15 min utes. If the
temperature continues decreasi ng, it continues to stop.
During this stop, the r oom tempe rature will blink.
Return to normal m ode:
The thermostat re turns automatic ally to norm al mode afte r the stop perio d.
The functi on can be overridde n b y pr essing th e (OK) butto n durin g the stop heating
phase.
The blinking temp erature should stop to indicat e the end of the d etection.
Special cases:
- This function do esn't work if The rmostat is in Fl oor regulati on
- This function do esn't work if The rmostat is in OFF / Antifreeze Mode
- If tempe rature is less than 10°C, th ermostat will regulates a t 10°C during the stop
phase (refer to ch apter 5, param eter 06)
- This function does n’t work in c ooling configur ation
4.3 Humidity measurement (*)
Thermostats measure the humi dity in the air. Thi s measure all ows:
- To regulate the humidity in the air (refer to par ameter 34 chap ter 8)
- To protect your system against co ndensation (r efer to param eter 35 chapte r 8).
4.4 Visualization
W ith this functio n, you can quickl y view the current temper atures of t he diff erent s ensors
connected to your thermostat (floor, remote, external). On the main s creen, press
several tim es on the esc ape key ( ) . This “scroll f unction” is only availa ble on t he main
screen:
You will see in the order of each press:
1/ the setting tempe rature follo wed by the therm ostat
2/ the ambient t emperature
3/ if the external s ensor is conn ected: the outside tempera ture
4/ the humidity perc entage (*)
Remarks :
- refer to chapter 1.2 for icon me anings
- if Parameter “S en ” is set on “Air ” (refe r to chapter 8 ), the remote sensor will be used as
an external sens or.
