Cool Run Values
Depending on the system conguration, adjusting the maxi-
mum compressor RPS (revolutions per second) may be re-
quired. Necessary adjustments to the maximum compressor
RPS are made through the following sub-menus.
Maximum Compressor RPS Range for Cooling
Select the range that your maximum compressor RPS
falls within.
Maximum Compressor RPS Selection for Cooling
Within the selected range, choose the specic maximum
compressor RPS for the system conguration.

This menu allows for the adjustment of several heating
perfor-mance variables. Heat Airow trim, Heat Fan ON
Delay, Heat Fan OFF Delay and timed Defrost interval can
be adjusted in this menu. Time inter-val of 30, 60, 90 and
120 minutes between two defrost cycles can be set to suit
the weather conditions and performance of the unit.

Similar to cooling mode, the maximum compressor speed
RPS (revolutions per second) can be adjusted for heating
mode under this menu.
