Coal-Trol Clock

Coal-Trol Clock

PostBy: Les3201 On: Fri Dec 30, 2011 5:08 pm

Hi. I have a Keystoker, Koker model with a coal-trol installed this past summer. Things are going reasonably well. We are still trying to fine-tune things with house temperature control....similar to some of the requests I am seeing here. My basic question right now is that we are seeing a lot of drift in our Coal-trol clock. If left un-adjusted, it will gain at least an hour (from the actual time) within several weeks or so. Is this indicative of a defective controller or should I be otherwise concerned?

Regards, and thanks in advance for any help.

If you don't use the setback feature and keep it at a set temp, the time shouldn't matter.

I leave mine at 65 all the time, never really even look at the time.

But the guys at coaltrol would know!

A drifting clock, particularly by that much, is a concern. We expect 60hz mains power and time our controller off that incoming power frequency. We will adjust speed control to handle a range of power frequencies, but as a general matter you should not have power running at a frequency as high as would be necessary to cause that kind of drift (what you're describing would be a fairly consistent 60.09 - 60.12hz, seems like a small difference but for a power company that would be usual).

An insecure thermostat cable connection can result in drift (though usually slow clock, not fast clock).

Otherwise there may be an issue with the controller itself.

Please give us a call, 315-299-3589, to discuss it and try some troubleshooting and/or arrange for warranty repair. It is possible, especially if you're running off grid for a significant time, that you do have an out of spec power frequency or running with "dirty" power which will present a problem for the controller.
