What is a Programmable Room Thermostat?
A programmable room thermostat is both a programmer and a room thermostat.
The programmer allows you to set “On” and “Off” periods to suit your own lifestyle.
The 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 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 & 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.
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.
If your heating system is a boiler with radiators, there will usually be only one
programmable room thermostat to control the whole house. But you can have
different temperatures in individual rooms by installing thermostatic radiator valves
(TRVs) on individual radiators.
If you don’t have TRVs, you should choose a temperature that is reasonable for the
whole house. If you do have TRVs, you can choose a slightly higher setting to make
sure that even the coldest room is comfortable, then prevent any overheating in other
rooms by adjusting the TRVs.
You are able to temporarily adjust the heating program by overriding or using the
temperature hold feature. These features are explained further on pages 14 and 15 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 Touch Series 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
Carefully separate the front half of the thermostat from the back plate by placing a
small flat head terminal driver into the slots on the bottom face of the thermostat.
Step 2
Place the thermostat front somewhere safe.
Terminate the thermostat as shown in the diagrams on pages 27-28 of this booklet.
Step 3
Screw the thermostat back plate securely into the back box.
Step 4
Clip the front of the thermostat back onto the thermostat back plate.
Do
Mount the thermostat at eye level.
Read the instructions fully so you get the best from our product.
Don’t

Comfort levels allow you to set different temperatures throughout the day. For example,
you may want the home warm in the morning when you are getting ready for work,
cooler during the day when the house is unoccupied and then warmer in the evening
when you are home relaxing.
The thermostat offers 2 programming options:
5/2 Day Programming - 4 levels for the weekdays and 4 different levels for the weekend.
7 Day Programming - 4 levels for each day.
See page 21 for details on how to switch between these modes.
Tip! If you don’t want to use all of the comfort levels, just set the time to --.--
Default comfort levels are pre-programmed but you can change them easily.

THE FOLLOWING SETTINGS ARE OPTIONAL AND IN MOST CASES
NEED NOT BE ADJUSTED
Feature 01 – Temperature Format: This function allows you to select between °C or °F.
Feature 02 - Switching Differential: This function allows you to increase the switching
differential of the thermostat. The default is 1°C which means the thermostat will
switch the heating on 1°C below the set temperature and will turn it off when the set
temperature is achieved. With a 2°C differential, the heating will switch on 2°C below the
set temperature and will switch off when the set temperature is achieved.
Feature 03 - Frost Protect: You can set whether the thermostat will maintain the frost
temperature when the thermostat display is turned off. As a default, this is enabled.
Feature 04 – Frost Protect Temperature: This is the temperature maintained when the
thermostat is in frost mode. The range is 07-17°C. The default is 12°C and is suitable for
most applications.
Feature 05 – Output Delay: To prevent rapid switching, an output delay can be entered.
This can be set from 00 -15 minutes. The default is 00 which means there is no delay.
Feature 06 – Communication Address: This setting is used when you have connected
your thermostat to a network system. Each thermostat on the network must have a
unique communication address. This can be set from 01-32.
