I have a Worcester-Bosch Greenstar HE Plus (ZWBR 11-35) boiler with the
in-built timer. Rather than fit the recommended thermostat which controls
the boiler via the electronics (Heatronic), I chose to have a third-party
radio thermostat (Draper). Worcester told me to connect it to the terminal
block, which I have done. They also told me that the thermostat would not
turn off the pump, only the boiler, which is indeed the case. This is
getting me down, because I'd like to be able to turn the thermostat down and
not have the pump on all the time.
Does anyone know of a way around this? Perhaps linking the thermostat up to
the Heatronic control?
Any help would be appreciated.

With this sort of boiler the only lost energy doing things the way they
say is on the pump which is not a huge saving although it might save a
few quid a year in electricity.
