IDENTIFY CENTRAL HEATING ELECTRONIC PROGRAMMER TO REPLACE

[Mellors500]

We own a house with an old central heating programmer which is not working correctly (hot water only works with heating on).I am thinking of replacing it but the lid with the name is missing. It is rectangular plastic with a display window set to left hand side with separate sliders for the central heating & hot water at the bottom. There is a vertical slide bar to the right hand side with run,set on it. Can anyone identify this for me and advise which one I need to replace it. The thermostat on landing doesn't seem to control temperature either - can anyone suggest what the problem is?

No the drop down cover is on the right hand side with sliders at the bottom. I am going to photograph it over the weekend to help

Last guess. Sounds like a Honeywell 6400C

No longer made, although someone (as usual) is selling old stock on ebay.

The much improved replacement for this model is the Honeywell ST9400C.

The one on eBay is new.

But production ceased 18 months ago. Plumbcentre sell a programmer that looks identical with a Wolseley branding.
