Looks as if your boiler is over firing (extended run) you probably have a faulty sensing thermostatic probe causing this the switch you are resetting is a safty pressure switch it is designed to keep the pressure from building which could cause the boiler to explode.

Can't help you directly, but Honeywell will have user instructions on their website.
It's something like holding the 'stat within a metre of the boiler when the batteries are inserted. Best to RTFI.

Hhow to set the pressuretrol??


Hi,
I assume you are talking about a steam heating system...
There are two screws on the top of the pressuretrol...


turn the pressure screw down to the lowest pressure at which you still get heat to the farthermost radiator...make sure the vents are working...or steam does not flow to displace the air...
Then just give the differential screw enough difference so the boiler cycles on and of a bout three times and hour...when making steam...
That's all there is too it...

When the grey bits are pushed in the boiler is set to come on for that 15 min incriment. Push they grey pins "in" for the required length of time you want the heating on and then set your manual on off switch to the middle position which will activate the clock to run through the set time sequence you have put in.

Baxi boiler timer


1)Push all the little pins (bits) inward toward the centre of the dial
2)Set timer to correct time by
turning dial to current time, ie if present time is 4.00 p.m.
Turn the dial until 4.00 p.m is aligned with the arrow symbol
3)PULL OUT all the ( bits) toward the outer edge of the dial to set the time that you want the heating to come on .eg pull out all pins between 6.00am and 9.00am(as each pin represents 15 minutesyou should have 12 pins pushed out)
4) Ensure the3 way switch in the middle of dial is in the middle position(timer) if it is at top position boiler is(constant on)and at bottom positon boiler is turned off.

I have a honeywell PA404A pressure control switch on my home gas steam heating system. I'm having a problem with the switch turning off the system. It will only come back on if I turn the top screw all the...


This may be caused by accumulation of sludge in the steam trap (the looped tube that connects the pressuretrol unit to the boiler). the sludge restricts the pressure from reaching the diaphragm in the pressuretrol unit. So it gets a false reading. Clean or replace the tube and see if normal function resumes.
