Electrical Connections: - If in any doubt whatsoever, do not continue, but consult a qualified electrician or heating engineer.
WARNING: ISOLATE THE MAINS SUPPLY BEFORE COMMENCING INSTALLATION
For existing wireless installations, remove the old relay box to expose the wiring back to the heating system / wiring centre. Check the wiring at both ends to correctly identify which wire is Live, Neutral, Switched Live and any Earth connec- tions.
For new installations, run a new cable between the heating system and chosen Relay Unit Location. The recommended cable size is 1.0mm2. See diagram below.
