Why is the Top Radiator Cold? This weeks video
You've been bleeding the radiator for five minutes and not getting air. The system pressure is high enough and yet the rad is cold but the first floor is warm. In this video, I chat about the two two most common types of hydronic heating loops, Direct and Reverse return. Hope you like it.

Contact Tunstall. They can find the right replacement.
Re: Wiring zone valve in Crown Boiler AWR series
@TNewm22 Connecting the circulator to the ZVC will stop the circulator at the same time as the zone valve call for heat is finished. With the circulator wired to the ARW boiler control there will be a one to three second delay on the circulator shutting off due to the zone valve end switch and the electronics in the ARW microprocessor control. this could cause the Woosh. However, if there is a second zone operating when the zone that is experiencing the Woosh thermostat is satisfied, you may still get that noise.
The only way to see if that will solve the problem is to try it.

This is the diagram to wire without the zone control

Re: Radiator Fitting
It might be easiest to just get another 1 1/2" valve to do the job in the place of the 90 ell.
We assume that this is hot water…..not steam?
Re: Water trickling sound in hydronic baseboards- please help
Thanks for the responses! Very helpful!
I guess that's what I'll try - increase circulator pump speed and try bleeding a 2nd floor bleed valve (and hope it works for a 60 year old baseboard). Hopefully the combination does the trick...
Re: Pneumatic Thermostat System
you might be able to buy the parts branded as parker or whoever makes them for johnson controls for a lot less. the preassembled stations are going to be a lot more than the parts
Re: Baffled: Weil-Mclain startup and delay on break relay
Although I did see it in that YouTube video that the person in the video complained the timer was hooked up backwards (with no real demonstration and resolution in the video, I think there was other issues), I would say in this case it does not matter. IMO it does not matter which way terminals 1 and 3 are connected, for two reasons, first it is a series circuit (it's only a two wire device), also it is an AC series circuit. Secondly (at least with the ICM203F) the terminals 1 and 3 immediately goes through a bridge rectifier circuit inside the timer and it does not care either way about terminals 1 and 3.
Your connection details may be helpful to others if they have never worked with relays and/or this type of timer before.
Thanks.
