Operating instructions

8. Mounting the ‘FHT80B-3’ to a wall

a) Choosing a suitable installation location

Choose a suitable location for mounting the ‘FHT80B-3’ heating control. This has to meet the

following requirements:

• Central position in the room in which the temperature is to be controlled

• Easy access for convenient operation

• Installation at eye level for easy reading of the display

• Not a poorly insulated outer wall

• No direct sunlight

• No interference from heat sources such as radiators, TVs, lamps, refrigerators, etc.

• No mounting next to a window

• The greatest possible distance to metal objects to avoid any unnecessary reduction of the

operating range

b) Mounting the wall holder

Proceed as follows to mount the wall holder:

• Remove the wall holder from the back of the heating control,

by sliding it down and out.

• Place the wall holder vertically against the wall with the round

side pointing up, see figure 2.

• Mark the positions of the bore holes through the two slotted

holes.

• Depending on the type of wall, drill 6mm holes and insert

suitable dowels before mounting the holder.
