Has anyone experienced the fan on their gas cooker coming on when the heating is activated using wireless controls?

This has happened twice, I switched the heating on while upstairs and when I came down the fan was running on the cooker.
Asked by: Anneo

How does this unit interract with an existing thermostat or does it override that?

I have a faulty ST9400C and plan to replace it with this unit. There is an existing thermostat and boiler stat with two-way motorised valve - any problems?
Asked by: Anonymous
The RF2 Pack 2 has an ST9420 programmer, which can communicate wirelessly with the supplied thermostat. The ST9400C requires a hard wired thermostat. If the ST9400C is replaced with this unit then some wiring alterations will be required to make use of its features.
