The C365 wireless thermostat controls heating, cooling and
airflow to the upstairs and downstairs using an upstairs and
downstairs wireless, modulating damper. A wireless, battery
powered temperature sensor located upstairs monitors the
upstairs temperature and the temperature sensor in the C365
monitors the downstairs temperature.
The C365 adjusts the upstairs and downstairs airflow during
heating and cooling calls to maintain uniform upstairs and
downstairs temperatures.
