Thermostat setting often reverts to 70 degrees for no apparent reason. This is erratic and I **** observing and operating if rom a remote location. Two other thermostats don't do this. Is this a reset to a default setting?

    CHV-THSTAT Introduction Functions and Features The CHV-TSTAT and CHV-THSTAT series are wall-mounted universal thermostats that can be part of a Crestron Home capable of controlling one or two-stage heating and cooling systems. Each thermostat is available in three colors: almond, black and white. The suffix ‘A’, ‘B’, and ‘W’, respectively denotes color, e.g., CHV-TSTATB is a black unit.
