Mounting of sensor (figs 1 and 2)
The unit is used for comfort temperature control in rooms. The unit should
be mounted on an internal wall approx. 1.4-1.7 metres above the floor in
such a way as to allow free air circulation around it. Draughts and direct
sunlight or other heat sources must be avoided.

Setting up which room sensor is paired with which thermal actuator
(fig. 3)
Each unit can be set to operate a specific output which in turn controls a
thermal actuator on the manifold. A selector can be accessed under the
front cover of the unit where the number of its output (i.e. its channel no.)
can be set with a screwdriver.
Please note that channels 10 to 14 are marked as A through E on the
selector.
A unit set to CH1 will activate the thermal actuator connected to output 1
on the master. The channel number can be set before power is connected
to the system. The channel set on the unit can be subsequently changed
if needed. If two units are placed in the same room and set to the same
channel, temperature will be controlled by the average of the temperature
recorded by both room units.

WLTD3: Mounting of floor limit sensor (fig. 4)
Floor limit sensor
Units with floor limit sensor have a mechanical jumper on the printed circuit
board allowing limits to be set for MIN. or MAX. temperature regulation. If
set for MAX., the limit setting will be 27°C. If set for MIN., the limit setting
will be 17°C. These temperatures are fixed when used with masters WLM3-
1BA or WLM3-3BA unless the unit has been allocated to a zone group
controlled by a WLCT3 room controller. In this case, the limit settings can
be increased or decreased via the room controller. The limits then set will
apply to all relevant room sensors with floor limit sensor belonging to that
group. If a WLM3-1FS or WLM3-3FS master is used, the limit settings can
be changed using the programming buttons on the master.

Jumper removed: min. limitation
Jumper location, see fig. 5.
Max. temperature limitation is used to prevent the floor from becoming
too warm. This may be required if special floor surfaces (e.g. solid wood)
are used. The sensor should be positioned where it can read the true
temperature of the floor and should always be within the heated area.
Min. temperature limitation is used to keep the floor surface warm,
irrespective of room temperature. In tiled bathrooms or pool areas, for
