NOTES
- When in Cool mode use, the External/Room temperature sensor as the floor sensor displays an incorrect value on the thermostat screen
- Firmware versions TRM2fx (3.06 and 3.04 ) and TRM3 (4.00) do not support resetting energy consumption over z-wave. This feature has been added for future firmware updates which may support energy resets over z-wave. The only way to reset energy consumption on these firmware is to exclude and re-pair or factory reset the thermostats.
