Turning your thermostat/heating system on/off
LCD Display
Step 1
You will either have a dedicated floor heating ‘sub-
board’ or the relevant switching accessories will be
located in your Main Switchboard. Ensure the floor
heating ‘Main Switch’ and relevant circuit breakers for
the heated areas are in the ‘on’ (up) position to enable
power to your heating system.
Step 2
In the standby position your thermostat will display
‘OFF’. To turn on the thermostat press the ‘power’
button. When heating is no longer required, press the
‘power’ button to turn off the thermostat. If you have
an electric In-Slab (off-peak) system, instead of turning
the thermostat off you can simply turn off the floor
heating ‘Main Switch’ at your heating sub-board.
If your thermostat screen is blank (no display) during the
day, there is no power to your thermostat and generally
indicates you have an electric In-Slab ‘off-peak’ floor
heating system which operates during off-peak times
(11pm-7am), therefore the thermostat will only operate/
display during this period.
If you need to adjust temperatures outside off-peak times,
please contact your installer.
Setting the clock and day of the week
This thermostat is fitted with a real time clock. It is
essential that the clock time and day are set accurately
if you are operating in auto mode (require programmed
events). To set, follow these steps:
1. Touch the time display and the time will start
flashing. Use the up and down arrows to set
the time. By holding the arrow down the time
will change faster.
2. Press the ‘Next’ button to move the Day setting and
use the up and down arrows to get the correct day.
3. Press ‘Done’ to store and exit.
