General Notes - For use on the 1001 fitted with VMF7 Printed Circuit Board

*The central heating pump (32) will run to disperse heat if the temperature at the heat exchanger limit thermostat (50) is too high *The frost thermostat (51) will switch on the boiler for central heating if the temperature is too low.

*Fuse on P.C.B.: 2 Amp.
