seconds, before returning to display the room temperature again.

Setting your room temperature

Night-time temperature reduction

Overnight, or if you are out, it is best to set the thermostat to

a lower temperature, as it will save you energy. In general a

reduction of 5°C is recommended, but this will depend on your

heating system and the amount of insulation in your home.

Replacing the batteries

Your batteries should be replaced

when the symbol is displayed.

To do this, separate the thermostat

from the wiring plate and insert 2

new AA alkaline batteries in place

of the empty ones. Then reattach

the thermostat to the wiring plate.

Getting to know your display

Troubleshooting

Low batteries

If you see this battery icon then you need to

replace the batteries right away. See overleaf.

No power to the thermostat

If the thermostat screen is blank after initial installation,

then check the protective tab has been removed from

the batteries. Otherwise, try replacing the batteries.

RF communication error

If these icons are ashing, then there may be an

issue with the signal from the Boiler Relay. First

check there is mains power to the Boiler Relay. If this

does not resolve the problem, consult your installer.

If this icon is displayed then the thermostat is no

longer functioning and will need to be replaced.
