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.
After five 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 flash up for a few seconds, before returning to display the room temperature again.
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.
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.
Set Temperature Indicator
Means the figure on the screen is your set temperature, rather than your current room temerature.
Heating on
Means there is a requirement for some heating, so your boiler should either be on or cycling on/off.
Boiler Relay Connection
Means your thermostat is successfully connected to your Boiler Relay.
Internet Gateway Connection (optional)
Means your thermostat is successfully connected to your Internet Gateway.
Binding your thermostat to a RFG100 Internet Gateway
follow these steps to connect your thermostat:
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 flashing, 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.
