DIGITAL THERMOSTAT Cod. 49.6935.33
Introduction
Congratulations on the purchase of your new Digital
Thermostat. Thanks to the latest microprocessor technology,
the thermostat offers many convenient and energy-saving
features. Please read the following instructions fully before
installing your thermostat.
Overview of features and functions
Your Digital Thermostat incorporates preset daily programs
to suit different user lifestyle. The thermostat can be
programmed easily to accommodate existing user needs.
Thermostat is powered by 2 x AA batteries and can replace
most domestic thermostat.
Cautions! The digital thermostat has been designed to
switch a 230VAC power supply. The maximum load is 6
Amps (resistive) / 2 Amps (inductive).
Installation
Caution! Electricity can be lethal. Before beginning any
work, ensure that the electricity supply is switched off at the
mains. If in any doubt, consult a qualified electrician. If you
currently have a thermostat connected by 2 wires, you can
replace it directly with your new Digital Thermostat.
If not replacing an existing thermostat, you will need to
install a 2 wire cable to your heating system.
1.
Before carrying out any installation work, choose an
appropriate location for the Thermostat using the
following guidelines:
a.
Mount the Thermostat approximately 1,6m above
the floor.
b.
Only mount on interior walls (thermostat is not for
outdoor use)
c.
Avoid any location where the Digital Thermostat
could be exposed to directly sunlight.
d.
Avoid any location in proximity to a heater, cooker,
ventilation outlet.
e.
Avoid any location where there may be concealed,
boilers, pipework or chimney flues.
f.

2.
Detach the front cover by sliding it to the left. Remove
screw in battery compartment. Open the front housing
from the base by lifting from the left hand side.
3.
Unscrew the retaining screw to open the protective
cover. (See Fig. 2.2)
4.
If fitting this thermostat to an existing system, the
thermostat base must completely cover the hole in the
wall. If the thermostat doesn’t cover the hole, then fit
an intermediate plate over the hole to reduce its size.
The plate should be made from insulating material such
as wood or plastic. When positioning the thermostat
check the wires come in through the protective cover
hole.
5.
Connect the two wires to terminals 1 & 2. See Fig 3.1,
3.2.
Note! If the existing installation has neutral or earth
conductors, these must not be connected to the Digital
Thermostat. They must be made electrically safe.
6.
Reattach the protective cover to the Digital
Thermostat’s base and secure it with the retaining
screw.
7.
Reattach the front housing to the Thermostat’s base
and secure it with the retaining screw.
