Hunter programmable thermostat problem

[Mark W Modrall]

Hi...

we have one of those hunter programmable thermostats
downstairs and one upstairs. The downstairs zone also has
another, older thermostat that only controls the ac.

The problem is that the downstairs unit occasionally
just chooses to ignore the programming. Sometimes it keeps
heating past the point of the program, sometimes it doesn't
turn on when it's supposed to. It's not giving any kind of
low battery indicator.

I downloaded the manual from the hunter website, but
it doesn't offer a lot of help. Does anyone else have similar
experience with these? Is it just a bad unit, or would the
ac thermostat be somehow interfering? Both were in the house
when we bought them.

The upstairs unit seems to work fine, but my wife is
worried about the flakiness of the downstairs one.

thanks

Does the Hunter thermostat use batteries? They may just need to be
changed.

Welcome to the world of Hunter and Lux garbage....its called normal
operation for either of the brands....

If you want a new one, let me know as I have about 40 in 5 gallon buckets
that we took off this season alone..you can have all 40 for whatever it
costs to ship...
Thats how well they are looked at in the trade...
Might want to get one with a reputable name....Honeywell....White
Rodgers....Etc..

Any chance that it uses a set of open contact points that could stick,
or get dust in there? This might just be a very simple mechanical
problem.

The Hunter unit is designed to go a full degree higher than
the set point, and then when it gets to the leading edge of
'the next degree', it cuts off. Same sort of thing below the
set point, by one degree. So it essentially has a 3 degree
window of function range.
However, I recently considered replacing my Hunter, because
it was showing similarly erratic behaviour. And I'm not thrilled
that it took over a day to get accustomed to the change from
heating to cooling.
I put a LUX unit into my mother's house last year, and she is still
very pleased with it and its straightforward function.

I have an old Hunter. You can set it for a 1 degree differential
if I want. If its on 72, it comes on at 71 and goes off at 73. If the furnace
chamber is still hot, it will run until its cool, regardless of setpoint.
Other than bad buttons it has worked, except in the winter
time, if you walk up to it and get a static discharge, all the programming
must be redone. It also the type that sucks juice from the line or otherwise
works without a battery, and solid state control.
