Connection
The following diagrams are block diagrams.
The heat pump (PAC) inputs can be controlled by
means of dry switches, TBTS or 230 Veff. (refer to the
heat pump guide).
If one of the inputs (change-over or thermostat)
is controlled by 230 Veff, both inputs must be of the
230 Veff type.
Refer to the heat pump guide.
The room unit must be installed at a
height of around 1.5 m, within arm’s
reach to use the device. Remove the
batteries’ protective tabs.
To mount the unit on the
wall, it must be separated
from its support.
To do so, unlock the casing,
then separate the thermostat
from its base.
Unscrew the terminal box cover and
lift it up as high as it will go to block
it, then position the base on the wall
running the wires out through the
hole in the cover.
Secure the base using suitable
screws and screw anchors or fit
onto a flush-mounted box
(distance between centres 60 mm).
Connect the control wires.
Close the box and fully tighten the
terminal box cover screw.
