Notes: X-13 (ECM) motor speed changes.
All X-13 (ECM) motors have 5 speed tabs. Speed tab 1 is for continuous fan. Speed tab 2 (low static) and Speed tab 3 (high static) are for lower tonnage. Speed tab 4
(low static) and Speed tab 5 (high static) are for higher tonnage.
X-13 (ECM) air handlers are always shipped from factory at Speed tab 5, except for -4824, which is set at Speed tab 3. For instance, RHLL-HM2417JA is always
shipped at high static 2-ton airflow (Speed tab 5). To change to 1.5-ton airflow, move the blue wire to Speed tab 2 or 3 on the X-13 (ECM) motor.
The low static Speed tab 2 (lower tonnage) and 4 (higher tonnage) are used for external static below 0.5" WC. The high static Speed tab 3 (lower tonnage) and 5
(higher tonnage) are used for external static exceeding 0.5" WC. Move the blue wire to the appropriate Speed tab as required by the application needs.
• The airflow for continuous fan (Speed tab 1) is always set at 50% of the Speed tab 4.
• The above airflow table lists the airflow information for air handlers without heater and air handler with maximum heater allowed for each model.
• The following formula can be used to calculate the approximate airflow, if a smaller (N kW) than the maximum heater kit is installed.
Approximate Airflow = Airflow without heater – (Airflow without heater – Airflow with maximum heater) x (N kW/maximum heater kW)
