General Manual Revised: 03/15/99
• If room gradually cools so sensor is 3º colder (67ºF), discharge temperature resets up the full amount of its
authority (+18) to 88ºF.
• If room only cooled to 70ºF (2 degrees) the new discharge temperature would be
* 18 = 12°. Therefore 12°
+ 65ºF set point = 77º discharge.
• If the room had warmed above the temperature of the room thermostat, a similar reset action would occur
except the discharge temperature would be reduced.
