PROVIDE DISCONNECT MEANS AND OVERLOAD PROTECTION AS REQUIRED. 2 24V WIRING. M12685A Fig. 7. Typical wiring diagram of sail switch with humidifier. For H1008 Automatic Humidity Control wiring connections: IMPORTANT • Current sensing relay or sail switch is not needed with the Automatic Humidity Control. • Use 18-22 gauge insulated wire for proper wiring. We recommend stranded - tinned wire. Connect 24 Vac power to the 24 Vac HOT and COM terminals on the H1008A. 14. Connect the humidifier to the two HUM terminals on the H1008A as shown in Fig. 8. For additional mounting and wiring information, refer to the Humidity Control installation instructions. For Perfect Climate Comfort Center™ Control connections: 1. Connect only the two yellow wires to the W8900 (red wire connections are not used). See the typical wiring diagram in Fig. 9. For additional mounting and wiring information, refer to the Perfect Climate Comfort Center™ installation instructions. Plumbing Saddle Valve Hot or cold water, either hard or softened, can be used in the humidifier. 1. 1.Use the self-piercing saddle valve (included) to tap into the water supply line at an appropriate location. CAUTION Chemical Hazard. Can cause personal injury or equipment damage. Do not use any line connected to an air conditioner. IMPORTANT • •The saddle valve is not designed to regulate water flow; the valve is either open or closed. • •To prevent debris from clogging the solenoid in-line filter, be sure to install the saddle valve handle pointing toward the ceiling. NOTE: Lightly clean the copper tubing ends with fine sandpaper before making any connections. HVAC TrueIAQ R CWY G HUM YELLOW HUM R C W G 1 R Rc W Y G THERMOSTAT 1 If a thermostat other than TH5110, TH5220, TH5320, TH6110, TH6220, TH6320, TH8110, TH8320 or TH8321 is used, a relay may be required to isolate the G wire. M31027 Fig. 8. Typical wiring diagram for humidifier using TrueIAQ. 2. Use 1/4 in. O.D. copper tubing and connect the saddle valve to the inlet side of the solenoid valve. a. Place the brass compression nut over the copper tubing. b. Slide the brass ferrule over the tubing. NOTE: Do not over-tighten the compression nut. Moderate tightness prevents leaking. c. Insert the tubing into the solenoid valve fitting and support the valve while tightening the compression nut. NOTE: Slope hose downward for correct drainage. 3. Connect a 1/2 in. hose to the humidifier drain fitting and run it to a suitable drain. CHECKOUT 1. Open the saddle valve. NOTE: The furnace blower must be on for the humidifier to operate. 2. Set the thermostat setpoint 10°F (6°C) above the room temperature. 3. Set the humidity control to a high humidity setting, or place the setting in the test position. 4. Observe the water running out of the drain line to be sure the humidifier is working correctly. 5. Check for leaks. 6. Reset the thermostat to a comfortable setting or the Automatic Humidity Control to the desired frost factor setting.
