Honeywell home heating advice

[shankly1985]

Hello

In the hallway and a bed room up stairs we have honeywell t6360 thermostats on the wall, the kitchen we have on the wall honeywell st9100s and next to that is the boiler Vaillant ecoTEC Pro 28.

Now first question

does the downstairs T6360 control upstairs and upstairs controls downstairs?

does one of these control the hole house or can I use each one for setting the temperature around the home?

The T6360 downstairs I hear the clicking noise around 12c on the dial and the upstairs clicks around 25c



Any advice here helping us control the heating would be much apricated.

Upstairs should control upstairs, and downstairs should control downstairs, if this is different it’s likely wired up wrong. Heat rises, so would make sense where it’s clicks in at. The system is two zones, new each thermostat controls temperature in each zone.

Thanks for the reply
I am sure its me just doing something wrong here. But when I set the T60360 on each to 20c the heating on the rads just stops heating them up.

I would like to have downstairs heating much higher than upstairs and keep upstairs cooler. In this house up stairs is always much hotter and I guess like you pointed out heat rises so that would make sense.

Another question I guess for controlling the heating I must have the honeywell st9100s setting on continuous?

Thanks again

IF you want the heating on constant, set to constant, if you want timed periods then set timer. If you set to 20, then it sould reach 20. Location can play a part as well.

So I turned the downstairs T6360 all the way to the pass 30c and I set the upstairs to 25c all rads turned off lol I am confused.

I then put upstairs all the way back to pass 30c and all heating is back on again.

Sounds like either you have a port valve that’s faulty or it’s not wired correctly

From your description, I think it's possible that the system has been wired so that the boiler only comes on if both thermostats are calling for heat.

For systems where this has been done deliberately there is often some complicated back story involving a temporary fix that never got re-done properly.
