Should the thermostat on the side of the hot water tank be set to the same figure as that on the boiler?
Have a Maxol Morocco gas boiler, dial reads 0-5, whereas dial on tank reads 2-9. So should the dials be set to similar % of range - ie 1/2 way on dials: 2.5 boiler / 4.5 tank?
Reason I ask is that pump has been running almost continuously (with boiler not heating), turned thermo down on tank and that has turned pump off. Read somewhere that boiler usually turns pump on/off but have had a look at boiler and there are no wires connected to the "pump" terminals.
