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 “Off” 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 off 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
different temperatures in your home at different 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 affect 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.

Model: edge
The way to set and use your programmable room thermostat is to find the lowest
temperature settings that you are comfortable with at the different 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 flow of air to sense the temperature,
so they must not be covered by curtains or blocked by furniture. Nearby electric
fires, televisions, wall or table lamps may also prevent the thermostat from working
properly.

Installation Procedure
This thermostat is designed to be flush 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 edge LCD front plate somewhere safe.
Terminate the edge as shown in the diagrams on page 31-34 of this booklet.
Step 3
Screw the edge 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 first. 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 affect functionality.
Do not push hard on the LCD screen as this may cause irreparable damage.

This edge can be configured for different sensor options such as built sensor, floor
sensor or both. The display will clearly indicate which sensor is being used by showing
either ‘ROOM TEMP’ or ‘FLOOR TEMP’ to the left the actual value.
When the edge is set to use both the air & the floor sensor, the room temperature
will be displayed by default.

Pairing Accessories
You can pair a total of 16 accessories to a single edge thermostat.
Wireless Air Sensor
Once a remote sensor is added, the edge will automatically display an average
temperature between the ‘Wireless Air Sensor’ and the on-board sensor inside
the thermostat. Averaging will also be calculated between multiple Air Sensors.
Window/Door Wireless Contact Sensor
If any one of the ‘Window/Door’ contacts is broken, the edge
thermostat will be alerted and will activate ‘Frost Protection’ mode.
The display will now show the icon (right) to indicate a window or door has
been opened. Heating will not resume while this icon remains on screen.

Edit Comfort Levels
The edge offers three program mode options; Weekday/Weekend,
7 Day and 24 Hour programming. There is also the option to use the edge as
a manual thermostat.
The thermostat is supplied with comfort levels already factory programmed, but
these can be changed easily. The default times and temperature settings are;
07:00 - 21°C (Level 1) 09:00 - 16°C (Level 2) 16:00 - 21°C (Level 3) 22:00 - 16°C (Level 4)
Unused levels must be set to --:-- so that the edge will skip these and continue
on to the next programmed time.
For Weekday/Weekend programming, the four comfort levels are the same for Mon-Fri, but
can be different for Sat-Sun. For 7 Day programming each day of the week can have four
different comfort levels. In 24 Hour mode all days are programmed with the same comfort levels.
• To program the ‘Comfort Levels’, use the ‘Left/Right’ keys to scroll to ‘EDIT’ ......
• Press to confirm selection ......................................................................................................
• Use the‘Left/Right’keys to select day/period of week (the selection will flash) ......
• Press to confirm selection ......................................................................................................
‘Level 1’ will now flash and the current time and temperature setting will
be shown.
