Notes:
1.
Condenser fan will de-energize at 5ºF below the energizing temperature
2.
Compressor Stage 1 = CPR1
3.
Compressor Stage 2 = CPR2 or CPR3 depending on staging sequence
4.
Compressor Stage 3 = CPR1 & CPR2 or CPR2 & CPR3 depending on staging sequence
5.
Compressor Stage 4 = CPR2 & CPR3
6.
Compressor Stage 5 = CPR1 & CPR2 & CPR3
7.
Conventional three stage thermostat sequence: Y1=CPR1 (Stage 1), Y2=CPR1&2 (Stage 3), Y1 + Y2 = CPR1,2,3 (Stage 5)
8.
During active hot gas reheat all compressors will be staged "On". For units equipped with four condenser fans (40 and 50 Ton), the
condenser fan output states will be controlled based on the O/A temperature. If O/A is above 85°F, all condenser fan outputs will be
energized. If O/A falls below 80°F, Output B will de-energize and will not re-energize again until the O/A rises above 85°F. For units
configured with three condenser fans (27.5 to 35 Ton), a maximum of two condenser fans will energize. Output A will energize above 85°
F and de-energize when the O/A falls below 80°F; Output B will remain de-energized during active hot gas reheat. If O/A falls below 80°F,
Output A will de-energize and will not re-energize again until O/A rises above 85°F.
