I need to buy a 3 port motorised valve for my domestic system. Is the extra cost of Honeywell really justified against say a Sangamo valve? ( over twice as much )
Hey all,
i have one of these actuators, its Clicking and failing to turn off the heating, it's stuck always on.
I did try to get someone local to do it but 2 people failed to turn up so far, i guess because its a small job..most seem to want to install bathrooms etc!, or does anyone know...

I have two Honeywell programmers, an ST9400C 7 Day Two Channel Programmer and a ST9100C 7 Day Single Channel Programmer.
I have just noticed that they are quite hot to the touch in top left hand corner of each programmer.
Is this normal, I assume it could be as it is same on both programmers...

Hi

Hello!
The aforementioned mid position valve has been replaced on an open vented, Y plan system with 22mm primaries and 8mm feeds to radiators from manifolds (I know). The system is clean and all radiators are new. Heating and DHW are fine, both work as required and provide required heat...
Needed to swap a Honeywell zone valve head today for a neighbour in need! I only had a"Tower" one. They are identical, even the valve body us the same casting.

I have an old Honeywell st 499 controller with a battery back up that no longer works. I purchased a new battery and asked my plumber to fit it. For some reason this did not solve the problem. I am therefore considering replacing it with the newest version, the st 699.
As someone with no...
Hey all,
I've just moved into a new home that has a thermostat hooked up to a Honeywell ST6400C programmer. I'm trying to figur out how to leave the heating to come on only when the temperature drops below a certain level. Can anyone advise?
Just curious,
I need to change a 2 port valve, there is an iso just above it but not below, if it's a sealed system can I not just shut off the iso and replace without draining, and if a vented system bung the feed and vent and replace without draining?
It's a 2 floor house and the valve is on...
Hi
