This option turns on Quiet Shift function in 1-stage or 2-stage communicating heat pumps.
After the selection is made, touch SAVE.
NOTE: This option is not available with variable speed heat pumps nor geothermal units.
• Quiet Shift: On or Off. Default = Off

6.3.4.6. AC/Heat Pump RPM Max

Used with variable capacity heat pumps, this option clamps the operating speed of the heat
pump to this maximum. Used to reduce operating noise while in high heating capacity.
Reducing this value will reduce the heating capacity of the heat pump. After the selection is
made, touch SAVE.
• AC Heat Pump Max RPM: Adjustable from 4500 – 7000. Default = 7000 RPM

6.3.4.7. Defrost Fan Delay

Adjusts the airflow speed on non-communicating two-stage units. Choose 0.65 for units with a
Bristol compressor, choose 0.80 (default) for units with a Copeland scroll compressor.

6.3.4.10. Energy Efficiency

This option is used to input the published ratings of the installed air conditioner or heat pump as
part of the energy tracking calculation. After the ratings are entered, touch SAVE.

6.3.5. Heat Source Lockout

First touch SETUP, then touch HEAT SOURCE LOCKOUTS to set up the parameters for the
AC/Heat Pump unit.
For hydronic heat applications, this option allows the installer to set the lockout temperatures
below which only the hydronic coil will operate, and the lockout temperature above which the
hydronic coil will not operate. After the selections are made, touch SAVE.
