After installing the backplate in a suitable location, wiring connections can be made as
shown above. The following criteria apply to the installation:
• The incoming AC mains supply should be 230V AC and fused at 5 amps.
• Optimum cable size for installation is 1.5 mm
in accordance with the current requirements of the IEE Wiring Regulations.
• Cable entry should be from the rear of the backplate.
• All wiring connections should be securely made, and be firmly
gripped beneath the square brass washer on each terminal.
The RT300 requires two 'AA' alkaline batteries to function correctly. Ensure that the
batteries are inserted correctly, paying careful attention to the polarity markings on the
battery and next to the battery holders.
Do not restore the mains supply to the system until all associated items are fully installed.
NOTE: All electrical installation work should be carried out by a suitably qualified Electrician
or other competent person. If you are not sure how to install this thermostat consult either
with a qualified electrician, heating engineer or your boiler / heating system supplier for
advice on how to continue.
Do not remove or refit the RT300 onto the backplate without
the mains supply to the system being isolated.
