What is a Programmable Room Thermostat?
A programmable room thermostat is both a programmer and a room thermostat.
A programmer allows you to set “On” and “O”periods to suit your own lifestyle.
A room thermostat works by sensing the air temperature, switching on the heating when
the air temperature falls below the thermostat setting, and switching it o once this set
temperature has been reached.
So a programmable room thermostat lets you choose what times you want the heating
to be on, and what temperature it should reach while it is on. It will allow you to select
dierent temperatures in your home at dierent times of the day (and days of the week)
to meet your particular needs and preferences.
Setting a programmable room thermostat to a higher temperature will not make the
room heat up any faster. How quickly the room heats up depends on the design and size
of the heating system.
Similarly reducing the temperature setting does not aect how quickly the room cools
down. Setting a programmable room thermostat to a lower temperature will result in the
room being controlled at a lower temperature, and saves energy.

The way to set and use your programmable room thermostat is to nd the lowest
temperature settings that you are comfortable with at the dierent times you have
chosen, and then leave it alone to do its job.
The best way to do this is to set the room thermostat to a low temperature
– say 18°C , and then turn it up by 1°C each day until you are comfortable with the
temperature. You won’t have to adjust the thermostat further. Any adjustment above
this setting will waste energy and cost you more money.
You are able to temporarily adjust the heating program by overriding or using the
temperature hold feature. These features are explained further on pages 20 and 21
of this manual.
Programmable room thermostats need a free ow of air to sense the temperature,
so they must not be covered by curtains or blocked by furniture. Nearby electric
res, televisions, wall or table lamps may also prevent the thermostat from working
properly.

Installation Procedure
This thermostat is designed to be ush mounted and requires a back box of 35mm
(minimum depth) to be sunk into the wall prior to installation.
Step 1
Using a small screwdriver, slightly loosen the screw from the bottom face of the
thermostat. You can then carefully separate the front half from the back plate.
Step 2
Place the UFLEX EDGE LCD front plate somewhere safe.
Terminate the thermostat as shown in the diagrams on page 32-35 of this booklet.
Step 3
Screw the thermostat back plate securely into the back box.
Step 4
Replace the front of the thermostat onto the back plate, by locating the pins in the
socket then insert the top edge rst. Now push in the bottom edge, securing it in
place with the retaining screw.
Do
Mount the edge at eye level.
Read the instructions fully so you get the best from our product.
Don’t
Do not install near to a direct heat source as this will aect functionality.
Do not push hard on the LCD screen as this may cause irreparable damage.

Edit Comfort Levels
The UFLEX EDGE oers three program mode options; Weekday/Weekend,
7 Day and 24 Hour programming. There is also the option to use this device as
