The FP735 Si is a three channel programmer, depending on your home, the various channels, C1, C2 or C3 will be assigned to one or 

two heating zones (upstairs and downstairs) and the remaining channel for hot water.  Your installer should be able to confirm which 

channel has been assigned to hot water and which remaining channels are assigned to which heating zone.
The heating will not work if the room thermostat has switched the heating off. And, if you have a hot-water cylinder, the water heating 

will not work if the cylinder thermostat detects that the hot water has reached the correct temperature.
