WARNING: RISK OF ELECTRIC SHOCK
If you come across mains voltage wiring, professional installation required.
Always perform installation work with the power shut-o.
Touching energised electric parts can cause an electric shock.
Safety information.
WARNING
Please read the safety information carefully before installing the air conditioning
equipment and be sure to install it correctly. Improper installation may result in
electric shocks or fire.

9
Follow the relevant local and national codes and regulations when installing
the thermostat. Use a qualified installer, if required, for working on high voltage.
Make sure connections are properly secured and wiring is as per local codes.
Use only with compatible systems. Use with incompatible systems can cause
damage to the thermostat and fire.
This is a 24VAC device. Do not use on voltages greater than 30VAC.
This device has magnets. It may eect electronic devices, e.g. data storage media,
hearing aids or devices that can be aected by the magnets.
Do not disassemble or try to repair the thermostat. Do no short across thermostat
terminals to check equipment working. This can damage the thermostat and
void warranty. Use the security screw to mount the Hub securely, if required by
local codes.
