4. INSTALLATION.
4.1 CHOOSING A LOCATION FOR YOUR B16C
The B16C controller should be mounted on an internal wall approximately 1.5 meters from floor
level and should be in a position away from draughts, direct heat and sunlight.
4.2 INSTALLING THE B16C
The thermostat requires a one
gang back box having a
minimum depth of 35mm.
1) Remove the front screen
from the thermostat by
gently using a screwdriver
underneath the front lip to
release the two plastic clips.
Gently pull the screen towards you releasing the internal
plug which allows the two parts to be separated.
2) Now remove the plastic centre housing from the back plate
by gently lifting in the direction shown in the picture. Once
lifted gently pull towards you exposing the black metal back
plate.

3) Wire the thermostat as per picture 1
making sure all the terminals are
done up tightly. An under floor
sensor must be used (supplied) and
this MUST only be wired to terminals
5 and 6. Polarity of the sensor does
not matter. Do NOT exceed total
load of 16A. For loads greater than
this, use a contactor with the
thermostat controlling the coil of the
contactor.
4) Once all the connections have been
made, make sure the arrow on the
back plate faces upwards and secure
to the back box using two screws. See
picture 2 to the right.
5) Slide on the centre housing until it
clips into position. See picture 3
above.
6) Finally push the plug into the socket
on the front screen and clip onto the
centre housing. Note:- The plug only
fits one way around so don’t force it.
