CONVENTIONAL THERMOSTAT WIRING
The RHPL-series of air handlers are factory configured to for proper airflow. The cooling
airflow (CAF) is fixed and the DIP switch settings have no effect on airflow. The factory
setting is:
IMPORTANT: The DIP switches are active only when using conventional a 24VAC ther-
mostat. If using the Comfort Control
2
System™, refer to Section 5.13 for adjusting air-
flows.
*5.14 COOLING AIRFLOW ADJUSTMENTS WITH SINGLE STAGE
CONDENSING UNITS
The (-)HPL- series of air handlers can be used with select single-stage condensing
units. Refer to the Engineering Specifications Sheets to determine the required airflow
for your particular combination. Refer to Table 6 to determine the air-flows available for
each (-)HPL- air handler. Reference Figures 14-17 for proper wiring of the system.
5.15 HEATING AIRFLOW ADJUSTMENT
The RHPL-series of air handlers are factory configured to for proper airflow. The heat
pump airflow (PAF) is fixed and the DIP switch settings have no effect on airflow. The
factory setting is:
IMPORTANT: The DIP switches are active only when using conventional a 24VAC ther-
mostat. If using the Comfort Control
2
System™, refer to Section 5.14 for adjusting air-
flows.
