8 .2 Description of Functions

The following sections contain information on the
programmable functions available within the Q3 control.
1: Compressor Time Delay
If programmable function 19 is set to "CL", there will
be a five-minute time delay before the display shows
readings. If an attempt is made to change the five-minute
time delay, the changes will not be recognized by the
system.
2: Fahrenheit, Celsius, or Auto Selection
Select "F" for Fahrenheit. Select "C" for Celsius. Auto
selection defaults to 60 Hz and F.
3: Compressor Restart Differential
The compressor restart differential is the ambient
temperature change needed for the compressor to
cycle on and off. The factory setting of 1.5 °F (0.8 °C)

should be adequate for most applications. Differential
selections are available in increments of 1/8 °. All
program functions must be adjusted in °F, even if
the temperature display is changed from Fahrenheit
to Celsius (refer to "2: Fahrenheit, Celsius, or Auto
Selection" on page 19). To change the settings one
degree, add or subtract eight. Be careful not to set the
compressor restart differential too low. This will cause
the compressor to start and stop often, placing an undue
load on the electrical system and shortening the life of
the compressor.
4: Fan Response Differential
When the fan is in the Auto fan mode, the fan speed
is governed by how much the conditioned space
temperature differs from the set point. The fan runs faster
when the difference is greater. As the conditioned space
cools or warms, and the temperature approaches the set
point, the fan slows down automatically.
