I am looking for an owners manual for Mfr #: TH6110D1021 Honeywell thermostat. Can you help me locate one? I am having issues with the heat not coming on. I noticed it was stuck on HOLD mode, so I pressed the RUN button to get out of HOLD mode, and followed some steps I found on Google, but I am still not getting any heat on either the one upstairs or downstairs.
