Outdoor Air Enable
If this option is used, the Outdoor Air Temperature must be between
these setpoints for this Analog Output to function. See Figure 47.
Figure 47: Outdoor Air Enable Setpoints
Controlling Schedule
No matter what Control Method or Control Source has been selected,
each analog output can be confi gured to follow a schedule. See
Figure 48. Actual Schedules are set in the Schedules Window. See
instructions on page 33 for setting Schedules.
Enabling Relay
An Enabling Relay can also be selected. The operation of this Analog
Output will only occur once the Enabling Relay (based on its logic)
has energized. See Figure 49.
Figure 49: Enabling Relay
Enabling Binary Input
An Enabling Binary Input can also be selected (Figure 50). The
operation of this Analog Output will only occur once the selected
Binary Input is Active.
For example, if the Binary Input selected is confi gured as “N/O Con-
tact (Closes for Active),” then this Analog Output is enabled when
24 VAC is applied and the N/O Binary Input contact closes (Active).
If the Binary Input selected is confi gured as “N/C (Opens for Ac-
tive),” then this Analog Output will be enabled when 24 VAC is
removed and the N/C Binary Input contact opens (Active).

Output Voltage Limits
This output normally operates with a range of 0-10 VDC. If you need
it to operate with a different Min and/or Max voltage, those voltages
can be entered in the Output Voltage Limits Box (Figure 51).
