temperature to within ± 2ºF of the sensor setpoint at
the sensed location.

If the first stage of cooling cannot satisfy the cooling
requirement, the RTRM energizes the (K10) relay coil
located on the RTRM. When the (K10) relay contacts
close, the compressor contactor (CC2) coil is energized
provided the low pressure control (LPC2), high
pressure control (HPC2) and discharge line thermostat
(TDL 2) are closed. When the CC2 contacts close,
compressor (CPR2) starts to maintain the zone
temperature to within ± 2ºF of the sensor setpoint at
the sensed location.

controls.

Models configured for the multi-speed indoor motor
will be controlled via the 0-10 VDC or PWC indoor fan
speed output located on the RTOM. R136 (DA COOL_
FAN SPD) potentiometer on the RTOM sets the
maximum motor speed. Note that the potentiometer
voltage readings can be verified via 2-position harness
connector located adjacent to the RTOM. The unit
schematic will illustrate the exact location. Use a DC
voltmeter to read the voltage between the two
terminals. Provisions have been made in Service TEST
Mode to allow for maximum motor speed adjustment.
Motor may be adjusted using modes listed below.
Reference the RPM table in the Performance Data
section for fan speed.

1. TEST Mode Cool 2; 2-Step Cool applications only.

Adjust R136 potentiometer clockwise to increase or
counterclockwise to decrease motor speed.
