Re: residential boiler outdoor temperature sensor how to test
Just turn the knob all the way from one extreme to the other, it should click around the outside temperature number. That usually indicates it is working and accurate.
It's possible some other relay or control will be heard when you turn below the outdoor temperature. It is turning on the system.

Re: No water to third floor
We are talking about static pressure, here, not dynamic pressure. 20 PSI is more than adequate to raise water 30', as stated. The pressure EX tank has nothing to do with raising water, only acceptance of heated water in a closed sys. Verify pressure with an independent gauge that you can screw on the boiler drain valve hose connection, as stated.
A Fil-trol EX tank can have a stuck valve or plugged inlet screen or be water logged all which can prevent sys fill, just saying.
If you have verified 20+PSI and functioning air vents on the 3rd floor and no water release, look for closed shut off valves somewhere on the system. That would be my tact.

Or a sledgehammer. Or hire movers to deal with it.

Re: No water to third floor
Measure from the top of the highest radiator on the 3rd floor to the pressure gauge on the boiler. The measurement does not have to be exact but close. Next, divide that measurement by 2.3 to get the pressure setting for the boiler pressure gauge. Example; 23 feet /2.3= 10psi or 46 feet/2.3= 20 feet. So, whatever the distance you measure divided by 2.3 = the minimum pressure required to push the water up to the top of the highest radiator. Then add 1-2 lbs for safety to get the pressure where it needs to be. The next thing I would do is have the whole system serviced by a reputable service company. Check on this site for someone near you to fix all your problems.
Re: residential boiler outdoor temperature sensor how to test
If you do need to replace that control, consider an electronic setpoint control. It's digital reads temperature and has a lot more control settings.
Honeywell, Penn, Ranco, Johnson Controls are other brands. Should be less $$ compared to the old technology cap tube controls.

Re: Weil mclain ultra 105
on my boiler standby is shown when the boiler is at temperature or a no heat call
Depending on piping and control logic, a secondary or primary pump may still be running on a heat call but the boiler does not not need to fire if it is at temperature

Re: Turn down the heat?
as long as the return water stays above 140* it’s fine.
I don’t recommend keeping a home below 55°.
do you have any type of alarm system for when something goes wrong?
