NOTICE
Explanation
This will determine how often the ventilation
device will be opened
If ventilation mode is set to "Timed", the control
will allow ventilation per this setting per Ventila-
tion Cycle Time
If ventilation mode is set to "Timed", the control
will allow Ventilation Runtime per this setting
If there is a damper installed for ventilation pur-
poses
The touch screen will not allow ventilation if the
outdoor temperature exceeds this setting
The touch screen will not allow ventilation if the
outdoor temperatures is below this setting
There are additional settings for ventilation that
are covered with a temperature slider. These set-
tings will determine if the ventilator is opened
during a call for conditioning. The Touch Screen
Communicating Control will open ventilation any
time there is a call for conditioning if the outdoor
temperature falls in the "Ventilation with a heat-
ing/cooling call". Otherwise ventilation will run
with the indoor blower per the previously
described settings.
Finally the ventilation can be controlled per
indoor humidity. If the outdoor temperature is
above 50 degrees the touch screen can be set
so that it will disable ventilation if the indoor
humidity rises above the desired setting.
