#Red hot timer how to#

Since your boards are in different buildings I suspect one of them was acting up before the second one, you just happen to notice it after the fact as you were paying more attention.Īs suggested, it is probably time to replace the controls. What I'm getting at is look for a loose connection, might be a simple fix. We have repaired a few of these units by simply re-soldering connections that have failed over the years. You are going to see the clock motor, switching relays, resistors, capacitors and many other electrical connections. I suggest pulling the panels so you can inspect the back of the panel. This may be a longshot and an unlikely fix since both panels are acting up at the same tome. What could it be that this happens around the same time for two of the same boards at different locations?

I already tested it by calibrating the outdoor sensor, changing the outdoor sensor and the condensate sensor, so I don't think it's any of those causing the problem.

I'm familiar with how to use a multimeter, but there's no schematics so it's hard to think of where to start troubleshooting or what part is acting up in this case. I know these are old controls that aren't really supported anymore, but I wanted to see if anyone had any knowledge of where to start troubleshooting.

However, what's strange is that if I manually start the heating cycle timing by spinning the wheel, even if by a little bit to say 1 minute, the red light will stay on until the specified time dictated by the heating adjustment letter. The problem is as such, whenever the yellow light comes on indicating that the condensate has returned and the heating cycle has started, the timing wheel spins to around 5 and then stops the boiler. And the strange thing is that I have two of these controls that are doing the exact same thing at different buildings. I have a Heat Timer EPU that shuts off the red light way too early in the heating cycle, right around 5 minutes no matter what the heating setting is set to.
