How do you reset the Viconics VT7200, VT7300, & VT7600 LON series thermostats back to factory default values?
TAC I/A Series
Viconics VT7200, VT7300, VT7600
There's no button or command that sets the thermostat to its default parameter settings.
Either set them manually or through the snvts available via a LON integration. The Viconics Lon Integration Manual will help with identifying the proper snvts to use.
