The Reset feature allows the user to completely reset the thermostat and to register new
manual ˚F / ˚C temperature scale switch settings.
1. To erase all entered program settings, gently press RESET button using a paper clip or a
small pencil tip.
2. This will return all thermostat settings to their default values and register all new manual
˚F / ˚C temperature scale switch settings.
Non-Volatile Memory

thermostat has been stored for a long period of time in a cold
vehicle or location prior to being installed. The thermostat
should be allowed to warm up prior to installation to allow
proper heating control once installed.
