    Hi Adam,

    Thanks for the fast reply. Yes, I do have a Burnham and it's just 2 wires to the Honeywell T-stat (which has programmable time and day settings). I appreciate the walk-through offer. First I'm putting together a post to address my short cycling problem related to the thread with your post.

    I just swapped in a vaporstat (12 oz. cut-out, 8 oz. subtractive diff. on cut-in) for the pressuretrol on a new boiler that's a bit oversized by ~30% on EDR compared to radiator EDR. All new Gorton vents. The problem is pretty much on recovery from overnight 3-degree setback. After rads are almost all hot the pressure then rises to cut-out value. Once boiler shuts, pressure drops immediately to cut-in in less than a minute. It then takes 10+ min. to get the pressure back up again. So it looks like the short cycling is on pressure drop. Need to figure out if this is a vent problem. Will probably post this by tomorrow. Happy new year to you.

    Hi,
    I saw your post on setting up a timer in series with you thermostat in this post:
    https://forum.heatinghelp.com/discussion/comment/1490007/#Comment_1490007
    I think I have a similar situation to yours.
    I'd be grateful if you could give some details as to where you bought the timer or what parts you used to put it together. Also, any details on how you set it up and connected to the t-stat.
    Much thanks,
    Dave N.
