5.3I Temperature Cutout Programming
Ultra-Aire units produce heat when dehumidifying. Depending
on outside conditions, the ventilation function may introduce
warm air into the space. Occasionally, the operation of the
Ultra-Aire may produce enough heat to drive temperatures up.
The temperature cutout feature disables all Ultra-Aire operations
if temperatures reach cutout setpoint. In most installations this
feature will not need to be used. If temperature cutout is desired,
program the setpoint by pressing the
“PROGRAM ENTER”
button. Press RH until
“TEMP CUTOUT”
is flashing. Use
“RH”
up or
“RH”
down to adjust setpoints.
