DIP Switch Settings
Prior to powering unit, ensure that all DIP switches on SW2 & SW3 are set properly according to the tables below.

Dual Capacity/Single-Speed
Configures the control for single-speed compressor operation or dual capacity
operation.

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 capacity compressors.

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

Monitoring Disabled
ECM-ECM2 Blower/RPM

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) compat-
ibility. On is for all newer EH board (17P514A01) and ECM2 (round end).
Old EH & Old ECM Normal
SW 3- 5
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.

Freeze Detection Sensing
This DIP switch allows field selection of low source water thermistor fault sensing
for well water (30°F) or antifreeze-protected (15°F) earth loops.
