Thank you so much for this video. I wasn't given a manual OR a demonstration of this unit, I just discovered that it was wrongly wired in too which is why I've never been able to run just hot water with no heating unless I used the immersion heater! My programmer was placed on the wall at the side of the hot water tank so it's unfortunately not only pretty dark but it's hard to see the display and almost impossible to read the writing at the side of the switches. This is a very clear, understandable guide to what the switches are, how to use them and how to skip the 3rd time period during the day and just have morning & evening heating. Honeywell no longer even carry the print version of this programmer so your guide is brilliant for anyone who inherited this unit with their new home. Thanks again.
@@MH-bf4uu We put it on the auto setting so we could get heat as my boiler just wasn't staying alight. This worked fora few weeks but we ended up having to buy a new boiler although we do still have this thermostat. Good luck
The hot water side of my timer (honeywell ST6400C) is working fine. But the signal for hot water is not. The red light is coming on but the boiler and pump are not kicking in. Any ideas would be appreciated !
After setting times for both hot water and heating, what should the horizontal and vertical sliders be set on ? Many people in the comments have the same question. Please advise
Hi there, how do you set the temperature? Because the heating is ON on "cont", but it still doesn't work at all and obviously I would like to set up the temperature. I can't find any instructions for that at all.
Since this has unique bars for hot water and heating, is it actualy better than the newer 9400c as you can quickly switch off the heating or water individually with the 6400c?
Programmed hot water exactly as video showed. Set it to go off at 11:50am everyday. I came back home at 12:30pm after going out somewhere and it was still on :/ Any ideas?
Please help! On mine, the red light next to heating is flashing when I move the slider to auto, once or continuous and the heating is not turning on. Can you please advise? Thank you!

Moved into a new area and was clueless on how set the Timeswitch. This video saved my life! Thank you very much for this simple and excellent video.

Just replaced an older Honeywell with this type, thank you for publishing this great video, solved my problems.
Hi, any idea how to set up the temperature?
@@laurentm8681 use room thermostat and hot water thermostat. The programmer | timer does not control temperature.
Moved into a new house and has this older device. So helpful! Thank you!
Thank you very much, I moved into a property that is equipped with this device . Had no idea how to operate it. Looks like a pretty old model.
Great video guys. Daughter just moved house and it has one of these. Now we can program it!

Thanks. couldn’t work this out and at least we now have heating until we can sort it out long term.

I have an issue where the heating turns on even if it is set to off when the hot water is on. Please does anyone have any advise on how to fix this?
hi,thanbks 4 your upload.do i nid to run it for hrs before it heats up the room

With this thermostat if I'm correct as have the same one, you cannot get this to switch on automatically if it dips below a set temperature?
Thank you for video

When I put the water on the heating is coming on as well on all radiators except 2. The light is on at the water and faintly lit on heating.
I tried heating on continuous and the light is on suggesting it's on but none of the radiators seem to be hot
Really useful. Thanks mate!
Hi, in the auto mode can we set only 3 timers?
Hi when I try to programme it, all the days of the week are highlighted instead of one day at a time Any solution to it
Which mode should i use for energy saving? Auto or continuous?i have the st6100c model.thanks
Cheers!
Please help! On mine, the red light next to heating is flashing when I move the slider to auto, once or continuous and the heating is not turning on. Can you please advise? Thank you!
Beni did you manage to fix it? I have this same problem now, what do I do?
@@alekslife3866, hi, we had it replaced. I suggest calling a professional to replace it as it is most likely broken.

Found it on the manual. The slider must be set to AUTO for it to operate according to the heating/hot water programme.
Once you have set the times and put the switch on run programme, where should the hot water and heating switches be placed on? Thats what im having trouble with
I think they need to be on auto if understood correctly, still trying to figure out too
Same question
Found it on the manual. The slider must be set to AUTO for it to operate according to the heating/hot water programme.
So after setting the on and off settings. Do I leave the slider at once or auto?
I thought I was the only one with this question
@roydenpereira5726 Auto if you want it on continuesly
Thanks! Very usefull video.
