After ve seconds the current room temperature will be
displayed once again. The thermostat will then try to
maintain your set temperature as accurately as possible.
You can check your set temperature by turning the dial one ‘click’
to the left or right. The set temperature will ash up for a few
seconds, before returning to display the room temperature again.
Setting your room temperature
Your current room temperature is shown in the display.
To set the temperature you want, just turn the dial
right to increase and left to decrease. Each ‘click’
as the dial turns represents a 0.5º change.

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.

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.
Defective thermostat
If this icon is displayed then the thermostat is no
longer functioning and will need to be replaced.

signal between the devices will
appear on the thermostat for a
few seconds. 1 equals the lowest

need to use the Honeywell RFG100 Internet Gateway

in the RFG100 box, and at the relevant binding stage
follow these steps to connect your thermostat:
1. Touch and hold the right-hand
touch zone for about 10 seconds
to activate the binding screen.
