OVERVIEW
This electronic room thermostat (Fig. 1) is suitable
for reliable and accurate temperature regulation in
commercial and industrial premises as well as for
home installation.
OPERATION
When the measured room temperature is below the
value set on the dial the thermostat turns the relay
on and, at the same time, turns the red LED on for
'Heating'.
SETTING THE ROOM TEMPERATURE
The user can set the room temperature by moving
the dial to any desired temperature between
6°C and 30°C, in one degree steps, against the
index mark next to the dial at the 9 o'clock position.
INSTALLATION
WARNING
1. Please ensure that the electrical wiring of the
installation and connections to and from the
thermostat and any remote sensor connected
to it are in accordance with BS 7671, the
latest edition of the IEE Wiring Regulations.
3. The thermostat must be wired to the electric
mains through a switch capable of disconnecting
all poles compliant to the current safety
standards and with a contact separation of at
least 3 mm in all poles.
4. Before commencing work on the installation,
the electricity supply must be disconnected.
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:
1. First remove the dial by inserting a small
screwdriver in the slot (2) and lifting the dial off
carefully.
2. Remove the front cover by disengaging the two
plastic teeth on the right hand side of the case
as shown in Figs. 2 & 3.
3. The thermostat has been designed for fixed
wiring only. Cable access is through the rear of
the mounting backplate as shown in Fig. 4
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
Fig. 4
4. Fix the thermostat backplate to the wall through
the two screw holes with distance between
centres of 60 mm.
5. Make the wiring connections to the backplate as
shown in Fig. 5 including any remote sensor
connections to terminals 6 and 7.
6. 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. Refit
the dial aligning the 'D' shape to the spindle.
TEMPERATURE RANGE LIMITING
It is possible to limit the rotation range for the dial
by following these steps:
1. First remove the dial by inserting a small
screwdriver in the slot (2) and lifting the dial off
carefully.
2. Pick up the plastic pins (4) parked to the left of
the knob area and set them (5) as shown in of
Fig. 6. In this example the rotation range (6) is
reduced to the angle shown.
NIGHT SET BACK
Terminal NSB (6) Fig.5 allows to activate the "night
set back" mode. The night set back temperature is
adjustable in the range 2 °C to 7°C by means of the
internal trimmer (8) Fig. 7. The thermostat is factory
set to 4,5°C night set back.
REMOTE SENSOR SELECTION
When using the remote sensor option with the
thermostat, connect the sensor as shown in Fig. 5
(7) and remove the jumper on the bottom right hand
corner of the backplate - see (9) Fig. 7. Cased
remote sensors must be connected in cable of at
least 1.5mm
2
cross sectional area and not greater
than 25m in length. Do not put mains cables and
sensor cables next to one another.
