Connection

The following diagrams are block diagrams.The heat pump (PAC) inputs can be controlled bymeans of dry switches, TBTS or 230 Veff. (refer to theheat pump guide).If one of the inputs (change-over or thermostat)is controlled by 230 Veff, both inputs must be of the230 Veff type.Refer to the heat pump guide.

The room unit must be installed at aheight of around 1.5 m, within armsreach to use the device. Remove thebatteries protective tabs.

To mount the unit on thewall, it must be separatedfrom its support.To do so, unlock the casing,then separate the thermostatfrom its base.

Unscrew the terminal box cover andlift it up as high as it will go to blockit, then position the base on the wallrunning the wires out through thehole in the cover.Secure the base using suitablescrews and screw anchors or fitonto a flush-mounted box(distance between centres 60 mm).Connect the control wires.Close the box and fully tighten theterminal box cover screw.

If there is a difference between the temperature noted(thermometer) and the temperature measured anddisplayed by the unit, function 2-02 modifies the waythe probe takes measurements so as to compensatefor this difference.

E.g.If the temperaturedisplayed by the unit is19C and the temperaturemeasured is 20C, add1C to the display andconfirm by pressing OK.

Correction of themeasuredtemperature.

Correction possible from -5C to +5Cin increments of 0.1C.Press the + or - buttons to makechanges, and confirm with the OK button.

Important:In order to change this setting, the unit has to have been
