I have just had my old boiler replaced with an Ideal logic Heat15. I have a hot water storage tank and the programmer is a Honeywell ST9400C. I also have a Honeywell DT92E wireless thermostat . The problem is that the programmer switches the water on and off ok but I can only activate the central heating by using the wireless remote for the thermostat. The programmer lights up at the set times for central heating but does not ignite the boiler. Could it be a wiring problem or are the two methods of control incompatible?
Hope someone can help. Thanks.
