" Old unit went down typically when it was cold weather. Picked new unit up locally and fitted it.
Up and running within 30 mins from start to finish..
Fitted onto old backplate, bonus, programming easy.

Honeywell ST9400C programmer

" My ST6400C programmer failed whilst on holiday.
Bought this product (replacement model) and all I had to do was plug it straight onto the original backplate with no need to rewire.
This then ensured that all other thermostat controls in the house continued to work.

" My existing 9400C inexplicably failed after 8 years of service, I unhesitatingly replaced it with identical model.
This programmer will do absolutely everything any sensible person could possibly wish for, plus some other little niceties if you enter the "Installer Mode" routine "

" Needed to replace my 25yr old ST7100. Changed back-plate followed wiring instructions, switched back on - worked.
Screwfix not cheapest but available locally. Can't tell about reliability but would like to think this controller will also last 25yrs :)

" I reqired a controller for our local church which was versatile, easy to use and install. It replaced two timers controlling two zones and needed to be easily operated. A seven day programme was a must since Sunday is the main day.
Fitting was straight forward and the large display is excellent.
The override feature is very handy.

Honeywell ST9400C Programmer
16 Dec 2009

" a quality Replacement for my old, and faulty, timer/pgrammer.
clearly well buit, with sturdy casing and a good display window for easy reading in a poorly lit (under shelf) location.
A well written installation note ensured no problems with replacing an older Honeywell model.
but, as always, ensure the backplate is cleaned of debris My only problem was in the poor connectivity with the contact pins as previous debris prevented a flush fit - presenting as poor power connection and a therefore a 'dead' display.
Once the backplate was cleaned, and the new unit re-presented, this problem was never seen again "

" Brought as a direct replacement to another which had failed in auto mode, CH not coming ON as programmed, HW all OK.
After manual over ride all is well again?
One of the problems I find with all electronic
devises is that there is little you do beside
replacement.......built in obsolescence!
This is a good product with a fairly straight forward set up / programming, end user in
this case likes the features.

" I used this to replace an existing one that had only lasted a couple of years. After fitting (which was very easy due to the universal backplate) i spoke to a neighbour who told me about half the estate had had these programmers replaced. Maybe in hindsight i wouldn't have fitted it, however i can't fault it while it does work. Very good, easy to understand but fully featured. Excellent price as well. "
