Aux control
The TEC features an auxiliary output that you can
configure to operate in a few different ways. The available
Aux Mode options depend on whether the auxiliary
output is used for dehumidification control or not.
When Dehumidification is disabled, the Aux Mode
supports the following options:
• Not Used—Output is always off
• Occupied NO—Output is normally open, but closes
when occupied
• Occupied NC—Output is normally closed, but opens
when occupied
• Occupied Fan NO—Output is normally open, but is
closed when occupied with the fan running
• Occupied Fan NC—Output is normally closed, but is
open when occupied with the fan running
• On—Output is turned on (relay closed), used by a BAS
to directly control the AUX output
• Off—Output is turned off (relay open), used by a BAS to
directly control the AUX output
When Dehumidification is enabled, the Aux Mode
supports the following options:
• Dehumidifier—select when external or auxiliary
dehumidifier is connected to Aux BO. See Figure 9 and
Figure 10.
• Hot Gas Reheat—select when HGR valve is connected
to Aux BO. See Figure 11.

Scheduled circulation
About this task:
You can schedule to run your fan for a minimum duration
per hour during occupied or unoccupied hours. If the
minimum hourly fan runtime is not exceeded, the fan
turns on at the end of the hour for the length of time
required to fulfill the minimum run time. The fan runtime
calculation includes runtime initiated when the Fan Mode
is set to On and other overrides. The fan does not turn
on if the fan runtime is already longer than the minimum
hourly fan runtime. When you enabled the Scheduled
Circulation Only When Occupied setting, the fan does
not turn on at the end of the hour to fulfill the minimum
runtime unless the occupancy state is set to Occupied.
