Off Peak supply connection A suitable electrical connection must be taken from the Off Peak supply to the Electromax terminal block. The supply cable should be 1.5mm 2 cross sectional area 3 core HOFR sheathed cable and must be routed into the Electromax via one of the 20mm 3.3, page 10). The Live (Brown) conductor should be connected to the termination marked “OFF PEAK SUPPLY L”; the Neutral (Blue) conductor should be connected to the termination marked “OFF PEAK NEUTRAL N”; the Earth (Green/Yellow) conductor should be connected to one of the terminations marked “EARTH CONNECTIONS “. See section 6.1, page 19 for MCB and isolation requirements. 24 Hour supply connection (NB NOT Boiler connection) A suitable electrical connection must be taken from the 24 Hour supply to the Electromax terminal block. The supply cable should be 1.5mm 2 cross sectional area 3 core HOFR sheathed cable and must be routed into the Electromax via one of the 20mm 3.3, page 10). The Live (Brown) conductor should be connected to the termination marked “24 HOUR SUPPLY L”; the Neutral (Blue) conductor should be connected to the termination marked “ 24 HOUR NEUTRAL N”; the Earth (Green/Yellow) conductor should be connected to one of the terminations marked “EARTH CONNECTIONS “. See section 6.1, page 19 for MCB and isolation requirements. Pum p Fuse (3 Am p) Thermostat‘L’Fuse (3 Am p) Diagram 13 Electrical Supply Connection Block 20 Installation & Servicing Instructions
6.3 Boiler Connection (45 Amp) The Electromax boiler has a rated maximum output of 9kW at 240V ~ . The supply cable must therefore be separate and dedicated to the boiler. The supply cable should be a minimum of 6mm 2 cross sectional area, check the IEE Wiring Regulations for correct cable sizing). It must be routed into the Electromax (see section 3.3, page 10). The Live (Brown) conductor should be connected to the termination marked “L 45 AMP SUPPLY”; the Neutral (Blue) conductor should be connected to the termination marked “N 45AMP SUPPLY”; the Earth (Green/Yellow) conductor should be connected to the termination marked “ 45 AMP SUPPLY “. Where “twin and earth” cable is being used the bare earth conductor should be sleeved with suitable Green / Yellow earth cable sleeving. See section 6.1, page 19 for MCB and isolation requirements. 6.4 Programmable Room Thermostat Connection the Programmable Room Thermostat and Diagram 14 (Schematic Wiring Diagram). Connection to the Electromax should be with 2 core cable of 0.5mm 2 to 1.0mm 2 cross sectional area suitable for a 240V supply, bell wire MUST NOT be used. The cable must be routed into the Electromax via one (see section 3.3, page 10). One conductor should be connected to the termination marked “TO ROOM THERMOSTAT L”; the other conductor should be connected to the termination marked “FROM ROOM THERMOSTAT RUN”. Please note that the terminations on the Programmable Room Thermostat marked “B COM” and “C N/O” should be used. Connection to terminal “A N/C” will result in incorrect operation of the Electromax boiler. The clock function of the Programmable Room Thermostat is battery operated (2 x AA/ MN1500/LR alkaline batteries supplied).
