The TH6320ZW2003 T6 Thermostat

Just purchased four year old home with a Honeywell Zwave thermostat that doesn’t hold temperature. Seems to stay at set point at Home and Away, but at the Sleep point the set climbs to 82 degrees when I set all to hold on 75 degrees…

Hello,

This is a common occurance with this thermostat. Linked here are a few things to check to make sure the temperature stays on point and not drift from the schedule. Following that, the lower posts has guidance to remove the thermostat and factory reset to clear any pre-installed settings.

Please let me know if you continue to have trouble or which steps, if any, give you errors.

Tried the link you suggested and come up with an error code of “unable to process request” status code 514.

The link works for me. Maybe it was just a temporary error?
