Zoned/Finish on Second Stage
This switch allows the unit to down stage with the thermostat when off and finish with second
stage when on. Finish on second stage reduces stage changing in reciprocating dual capac-
ity compressors.

No RPM/RPM
Configures the control to monitor the RPM output of an ECM/ECM2 blower motor. When us-
ing IntelliZone or a PSC fan motor, the control should be configured for “NO RPM” sensing.

Electric heat and ECM2
Allows backward compatibility with older P Series. In the Off position this switch allows older
electric heat board (17P501A01) and older ECM (square end) compatibility. On is for all
newer EH board (17P514A01) and ECM2 (round end).

On dual capacity units this switch allows stage change: on the fly when off, and 1 minute
delay when on. A delay is required on all reciprocating dual capacity units.

Service Test Mode
On the control, allows field selection of “NORMAL” or “TEST” operational modes. Test mode
accelerates most timing functions 16 times to allow faster troubleshooting. Test mode also
allows viewing the “CURRENT” status of the fault inputs on the LED display.
