Supply Air

Use < Or > To Change

Select the Temperature Sensor that will determine the Heating, Cooling,

or Vent Mode of operation. The selections are:

 Supply Air

This is typical for VAV applications. Occupied Cooling

with Morning Warm-up.

 Outdoor Air

This is for 100% Outdoor Air (MUA) units.

Dehumidiﬁ cation utilizes a Dewpoint Calculation if

equipped with an Outdoor Air Humidity Sensor.

 Space Temperature

This is for any unit that conditions a space and is not 100%

Outdoor air. Occupied/Unoccupied Heating, Cooling, and

Vent Modes of operation.

 Return Air

This selection can be used when an Average Building

Temperature (the Return Air Temperature) needs to

determine Heating, Cooling, and Vent Modes of operation.

 Supply Air/Tempering

This selection is for VAV “cooling only” applications where

because of cold outdoor temperatures, even at minimum

damper position, you may need to enable heat to maintain

the cooling near its Cooling Supply Air Setpoint. When

heat is enabled during this sequence, it will control to

a non-adjustable setpoint that is 2ºF less than the Cooling

Supply Air Setpoint. Includes a Morning Warm-up

sequence.
