11—Typical 24V Wiring Diagram (Cont) required. The LCC for standard PSC blower products consists of a standard humidistat which opens contacts on humidity rise and a pilot duty relay with 24v coil. NOTE: If an LCC is desired, low-speed airflow must be maintained so that a minimum of 300 CFM/ton can be supplied during high speed LCC operation. Step 9—Make Airflow Selections AIRFLOW SELECTION FOR 58CVA/58MVP FURNACES The 58CVA/58MVP Non-Condensing Variable Speed Furnaces provide high-and low-speed blower operation to match the capacities of the compressor at high and low speeds. To select the recommended airflow and for adjustments to the manual switches labeled SW1, A/C and CF on the control board refer to the furnace Installation, Start-Up, and Operating Instructions. The 315AAV utilizes a control center that allows the installing technician to select the proper airflows. The A/C switch determines the airflow during high speed compressor operation. Airflow for hight and low speed can be calculated at either 350 CFM per ton or 400 CFM per ton based on the positions of SW1-5. AIRFLOW SELECTION FOR FK4C, FV4A, OR 40FK FAN COILS The FK4C and FV4A provide high-and low-speed blower operation to match the capacities of compressor at high and low speeds. To select recommended airflow, refer to the FK4C, FV4A, or 40FK Installation Instructions. The FK4C, FV4A, and 40FK utilize an EASY SELECT control board that allows the installing technician to select proper airflows. For adjustments to control board and recommended A/C SIZE and CFM ADJUST selections. This fan coil has an adjustable blower off delay factory set at 90 sec for high-and low-speed blower operation. For other combinations of equipment consult the Product Data Digest. 8 LEGEND 24 VOLT FACTORY WIRING 24 VOLT FIELD WIRING FIELD SPLICE CONNECTION RELAY SPDT, PILOT DUTY 24-V COIL (HN61KK324) OR EQUIVALENT HUMIDISTAT, OPENS ON HUMIDITY RISE (HL38MG026) AIRFLOW SELECTOR R1 H AFS LEGEND 24 VOLT FACTORY WIRING 24 VOLT FIELD WIRING FIELD SPLICE CONNECTION RELAY SPDT, PILOT DUTY 24-V COIL (HN61KK324) OR EQUIVALENT HUMIDISTAT, OPENS ON HUMIDITY RISE (HL38MG026) AIRFLOW SELECTOR R1 H AFS A01222 WIRING DIAGRAM NOTES: 1.
