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 “Setback” 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.

4 Model: Slimline-RF V3
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 wireless thermostat is designed to be surface mounted.
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
Mark 2 hole positions on the wall using the backplate as a positioning template.
Drill at the marked positions and insert a wall plug into each hole.
Step 3
Screw the thermostat back plate securely on the wall.
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
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.
