Had a look at my wiring centre and the wiring for the two port ch valve doesn't appear to have a brown wire - it looks black! Take programmer and back plate off, ignore the links between L, 5 and 8 as you won't need them on new programmer. We had the wiring diagrams for both units, and we carefully worked out where the different wires went.

it fitted the hole perfect, was exactly the right make and fit and works brilliant plus it looked very smart.Just looking for something as low cost as possible that I can control via the internet connection if I'm away from the home. Also my mate has the same Honeywell 699 programmer on a gas system and needs the same remote controllability as the programmer is in an inaccessible place. Honeywell Home ST699 1 Day Classic Programmer is an easy to use replacement programmer on gravity primary or fully pumped systems. I suspect that the Red wire from terminal 8 on ST699 to terminal 4 on ST9400c may be the problem, but not absolutely sure which terminal it should go to on 9400c.

When I examined the old control unit, I noticed the battery inside was dead and leaking so badly that the connection to the circuit board had corroded and loosen off. This thread is a few years old just wondering if I can resurrect it to see if there are any more alternatives out there now which are perhaps a better deal. We're sorry but this product has now been discontinued by Honeywell Heating Supplies and can no longer be purchased. before it packed in and I didn't think I would find a suitable switch for the wall but this was perfect. Item arrived all packaged intact and unopened part for an old boiler will be recommending and using this site again.The thermostat cable will be between terminal 4 on new programmer and brown of CH two port valve, connect brown of the CH valve directly to terminal 4 so it excludes the now redundant thermostat cable. purchased to replace an old unit, looks the same, wires up the same but they have changed the way you set the clock so now you cant set it up to any time you want the heating etc to come on, stupid idea and honeywell were useless with help and advice.

The Honeywell ST699 is an excellent product when new, but over the years the settings back-up battery fails so that if there is a power cut -off only for seconds, the settings have to be reset.
