Re: Honeywell quartz clock component

It looks like an extremely similar timer subassembly was used in the very popular Honeywell Chronos T8082A series thermostats such as T8082A-1148 (and maybe T8095 series such as the T8095A1002). Look for them on eBay and use one as a parts source.

Re: Honeywell quartz clock component

I have a very similar timer module in a Honeywell Chronotherm thermostat. My 2/3AAA solder-tab battery was also dead, but it caused the timer to stop. I tried a test with a AA alkaline battery, but 1.5 volts caused it to run fast. A NiMH AA battery worked great as a temporary fix. I simply used a heavy rubber-band to hold the leads onto the battery. That was the good news. The bad is that an hour ago I went to solder in a std AAA battery holder so I could use a std AAA NiMh and screwed up! I neglected to remove the thermostat before soldering...
