hello, this may a stupid question to some but to me it is not...i have
recently moved into another house...the current central heating system is run with a ...RANDALL 4033 PROGRAMMER....it has 2 switches...one that controls the hot water...the other controls the central heating ( radiators)...what i can gather the PROGRAMMER is approx 20yrs old...but still seems to work perfectly...my question therefore is....do i need to put both switches down to run just the central heating ?..for just the hot water i only put 1 switch down...but someone said that to run the radiators i had to put both switches down...even if i only wanted radiators on and NOT hot water,we also have a BAXI gas fire with a back boiler ( if that is of any importance)..many thanks in advance ![]() |
