I'm looking to reduce my bills in a rented property, which has an ancient boiler, standard old-style hot water tank with thermostat, and an LP722, no room thermostat.
So I want a programmer with a wireless thermostat, which is a drop in replacement for an LP722, as I can't fiddle with the wiring at all and need to reinstate the LP722 when I leave.
The drayton rf902 looks like it fits the bill, but none of the manuals say how it controls the hot water - anybody know? Is it a straightforward on-off time programme?
