New Honeywell V4073A1088 possible problem

[nomiwilts]

Hi - I have just had had a new Honeywell V4073A1088 valve installed (about 2 weeks ago) to sort out a heating problem I was having.

The heating refuses to switch off - even when slider switches programmer on boiler are set to OFF. I have had the programmer changed on the boiler - and it makes no difference - ie. the heating will not switch off - unless boiler is set to hot water first and thermostat dial is turned all the way off.

It has been suggested that the V4073A1088 valve could be stuck 'open'? I have checked the lever on it and it is set constantly to AUTO. I tried to move the lever manually - and found it extremely easy to slide back and forth. Could this problem be linked to the spring lever not installed properly?
Thanks

The indications are that the valve body has been installed the wrong way round, ie, hot water port to central heating and vice-versa.

or whoever wired the valve has made a mistake.

The side marked "B" should go towards the cylinder heating coil !

Thats a very basic mistake. What was the calibre of the person who fitted the valve?
