Communication Note
The discharge air sensor sends a temperature reading
signal to the Master Thermostat every 5 minutes, or if a set
temperature limit has been reached.
If the temperature has exceeded a set limit, the
Master Thermostat will shut off the heat or cool
source while leaving the fan energized.
It remains in this mode until the next temperature
reading signal. (5 Minutes)
At that time if the temperature limits are not
exceeded, the heat or cool source will be energized
if there is still a call.
