On LPG installations where an additional gas safety shut off valve is required, connect to L1 and N terminals on left side of lower terminal strip.
Install only one method of HWS temperature control. The use of an HWS sensor will allow no time control over hot water production. If timed hot water control is required then do not install an HWS sensor, but install only timeswitch & cylinder thermostat.
