I have a Honeywell Hometronic Manager HCM 200D controlling radiators (with HR80s) and a HS 30 switch for the hot-water (manual operation from the HS30 and timed operation from HCM 200D where I have a device set up as 'hot water') and a HC60NG controller for the central heating (manual control on HC60NG, boiler feedback from operation of the HR80s and automated control from the HCM 200D).

Is there a way of doing a factory reset on the HS30? Can't find any details in the manual or online on how to do this?
