3. Installation
3.1 Location of the controller
Thecontrollerissettoroomcontrolbydefault,whichmeansthattheinsidetemperatureisused
tocontrolthecentralheating.Thatiswhyitisbesttolocatethecontrolleronaninternalwallinthe
room in which you spend the most time, such as the living room.
Do not locate the controller too close to heat sources (fireplace, radiator, lamp, candles, direct
sunlightetc.),orinplaceswhereitmaybedraughty.

EN
Controller RF
• Positionthecontrolleratleast1metrefromequipmentwithelectromagneticemissionssuchas
washingmachines,Tumbledriers,wirelesstelephones,TVs,computers,microwaveovens,etc.
• Positionthecontrollersothatithasgoodreception.Takeaccountofthefactthatobjects
containing metal will affect the reception. These include steel-reinforced concrete, mirrors and
windows with a metal coating, insulating films etc.
TherangeofthecontrollerRFinbuildingsisgenerally30metres.
Note!
This value is purely an indication. The actual range of the RF signal depends strongly on the local
environment.Rememberthatthenumberofwallsandceilings(metalorotherwise)canhavea
(considerable)impactonreception.Otherobjectsthatcontainmetalmayalsoimpactreception.
These include mirrors and windows with a metal coating, insulating films etc.
iThe signal strength can be viewed via Menu > Information.
3.2 Installation and connection
Thefollowingmustbedonebeforeyouinstallandconnectthecontroller:
• AdjusttheboilersothatitcanbeconnectedtoacontrollerOpenTherm.
• Turnofftheboiler.
Consulttheboilerdocumentationforthisprocess.
OpenTherm is polarity insensitive; you may therefore swap the wires.

EN
Do this as follows:
R000249-A
OT
OT
(Controller OpenTherm only)PlacethreeAAbatteriesinthecontrollerifrequired.Thesearenot
provided.Thebatteriesensurethattheclockkeepsrunningwhentheboilerisswitchedoff.
ThebatteriesalsopowerthebacklightforthecontrollerforboilersthatdonothaveOpenTherm
Smart Power.
(Controller RF only)Place3AAbatteriesinthecontroller.Thesearerequiredtooperatethe
controller RF.
iThe controller is now ready for use. The base station needs to be installed for the controller RF.
Consult the base station RF documentation.
iThe programs that are set are saved if the boiler or the controller is switched off
(even if there are no batteries).
3.3 Location of the outside sensor
An outside temperature sensor is not supplied as standard with the controller. You only require this
sensor if you want weather-compensated control of the inside temperature.

8
EN
iConsult the documentation for your boiler for information on connecting an outside temperature
sensor.
3.4 Room sensor (for controller RF only)
AnRFroomsensorisavailableforthecontrollerRFasanoption.Thissensorreplacestheinternal
controller sensor.
4. Prior to rst use
4.1 Setting language, time and date
The menu for selecting the language (international version) or setting the time (Dutch version)
appears when you connect the controller.
1. SelectthedesiredlanguageifapplicablebyturningbuttonCandthenpushbuttonCtoconfirm.
2. Follow the instructions on the display to select the time, year, month and day.
The controller is now ready for use. After installation, the default program is activated
(see paragraph 4.2).Thetemperatureisnowcontrolledbythisclockprogram.
iThe controller automatically switches between summer time and winter time settings.
4.2 Default setting
Room control
Thecontrollerissettoroomcontrolbydefault.Thismeansthattheflowtemperatureofthecentral
heatingwateriscontrolledbythetemperatureintheroomwherethecontrollerisinstalled.

9
EN
Weather-compensatedboilercontrolisalsopossible(withoutsidesensor);inotherwordsbased
on the outside temperature. The controller has a programmed heating curve which determines the
waterflowtemperaturetogetherwiththeoutsidetemperature.Theheatingcurvemustbechosenso
thattheleastfavourableroomcanbeefficientlyheatedevenwhentheoutsidetemperatureisvery
low. See paragraph 5.5 for further information about weather-compensated control.
Clock program
The default clock program sets the temperature each day as follows:
• 06.00–19.00: 20°C
• 19.00–23.00: 21°C
• 23.00–06.00: 15°C+T
You can of course adapt the clock programs to your own requirements. See Chapter 5.
5. Setting
5.1 Three usage modes
The controller has three usage modes:
• Basic mode: no clock programs are used in this mode. You can only set the temperature on the
controller manually.
• Normal mode:thisisthestandardmode.Mostoptionsareavailable,suchastheclock
program.
• Extended mode:thismodeletsyouusetwostandardclockprograms(AandB),changemore
settings and request more detailed information.
You can change the usage mode via the menu: Menu > Settings > Users > User mode.

• Heating curve:
- Base outside:outsidetemperaturebasepoint
- Base flowtemp:flowtemperaturebasepoint
- Climate outside: outside temperature climate point
- Climate flowtemp: flow temperature climate point
- Curvature: degree of curvature of the heating curve, depending on your central heating
system. Select the relevant type of heaters: underfloor heating, radiators or convectors.
This will provide more comfort early and late in the year.
iThe heating curve is based on an outside temperature of 20°C. When the desired room
temperature is increased, the heating curve shifts upwards.

14
EN
The degree of increase is determined using the “RT effect” function.
• RT effect: factor influencing the shift in the heating curve.
• Heat limit day:outsidetemperatureabovewhichthecentralheatingisswitchedoffduringthe
day. The day temperature limit is relevant when the desired room temperature is higher than the
nighttemperaturethathasbeensetviaMenu > Program > Night temp.
• Heat limit night:outsidetemperatureabovewhichthecentralheatingisswitchedoffduringthe

The settings for the heating curve are highly dependent on the design of the central heating
systemandthehome.Thismeansthatnoclearadvicecanbegivenonthismatter.Theheating
curvecanbeoptimisedduringuse.Theheatingcurvealsoshiftsupwardsordownwardswhenthe
temperature is increased or decreased.
5.6 Setting a holiday program
Itcanbeusefultosetaholidayprogramifyouareawayfromhomeforsometime.
This ensures a constant temperature in your home for the period you set.
You set the temperature yourself.
A holiday program automatically takes effect at 0.00 hours on the start date and ends at 0.00 on the
end date.
Thesymbolxappears in the display.
This program is switched off and removed once the period set has ended.
You can set a maximum of 16 holiday programs.
You do this via Menu > Program > Holiday prog.:
• SelectView to look at the holiday programs set.
• SelectChange to change or remove programs.
• SelectEnter to add a new program.
• SelectDesired temp. to set the constant temperature.

Oncethetemperaturehasreachedthedesiredlevelintheroomwherethecontrollerhasbeen
positioned,thecentralheatingswitchesoff.Thismaybeinconvenientif,forexample,youhavean
open fire or if a lot of people are present in that room. Other rooms in the house are also no longer
heated in this situation.
You can switch on the “Fireplace” mode via the Programbuttonsothattheotherroomsarestill
heated.Thisswitchesoffthebuilt-inroomsensorinthecontroller.Thetemperatureofthecentral
heating water at that point is then maintained.
Ifitbecomestoocoldortoohotintheotherrooms,youcanincreaseordecreasetheroom
temperaturethereusingpush-turnbuttonConthecontroller.Thisincreasesordecreasesthe
central heating water temperature. You can fit thermostat valves to the radiators in order to
individually control the temperatures in these rooms.
iThe “Fireplace” mode should only be activated if the controller uses the room temperature to
control the temperature.
iWe advise that you close the radiator valves in the room in which the controller has been
positioned to prevent the room temperature there becoming too high.
iThe controller switches to weather-compensated control if the outside temperature sensor is
used.
