This electronic room thermostat (Fig. 1) is suitable
for reliable and accurate temperature regulation in
commercial and industrial premises as well as for
When the measured room temperature is below the
value set on the internal trimmer the thermostat
turns the relay on and, at the same time, turns the
red LED on for 'Heating'.
Through the internal temperature adjustment
trimmer, see ( ) Fig. 6, the user can set the
temperature around which the regulation will take
place, as explained above.
The thermostat should be positioned about 1.5m
from floor level and must avoid being positioned
near draughts, sources of heat or cold or direct
sunlight. To install the thermostat:
Remove the front cover by disengaging the two
plastic teeth on the right hand side of the case
as shown in Figs. 3 & 4.
The thermostat has been designed for fixed
wiring only. Cable access is through the rear of
the mounting backplate as shown in Fig. 2
The backplate can be secured either to a flat
vertical mounting surface or to a single gang flush
mounted wiring box: the fixing centres are shown in
Fix the thermostat backplate to the wall through
the two screw holes with distance between
centres of 60 mm.
Make the wiring connections to the backplate as
shown in Fig. 5 including any remote sensor
connections to terminals 6 and 7.
When the electrical connections are complete,
refit the cover by aligning the four plastic teeth
on the backplate with the holes in the cover and
then press gently to snap them together.
Terminal Fig. 5 energises the "night setback"
mode. The night setback temperature is adjustable
from 2 °C to 7°C by means of the internal trimmer
( ) Fig. 6. The trimmer is factory set to 4.5°C.
When using the remote sensor option with the
thermostat, connect the sensor as shown in Fig. 5
( ) and remove the jumper on the bottom right hand
corner of the backplate - see ( ) Fig. 6. Cased
remote sensors must be connected in cable of at
cross sectional area and not greater
than 25m in length. Do not put mains cables and
sensor cables next to one another.
