Wiring the Humidifier

CAUTION: Hazardous Voltage. Can cause personal injury or equipment damage. Disconnect the power supply before installing or servicing.

• On multispeed blower applications, do not wire the high voltage side of the transformer to the same power source that services the furnace blower, as premature transformer burnout may occur.

All wiring must comply with applicable local codes, ordinances, and regulations.

1. Mount the transformer in a convenient location.
2. Connect wires to the 120V side of the transformer.
3. Wire the humidifier solenoid valve, current sensing relay, or sail switch, humidity control, and transformer. Refer to the humidity control installation instructions for mounting and wiring information.

NOTE: Select models of fan centers include humidifier taps, so the current sensing relay or sail switch is not needed.

Plumbing the Saddle Valve

Hot or cold water, either hard or softened, can be used in the humidifier.

1. Use the self-piercing saddle valve (included) to tap into the water supply line at an appropriate location.

IMPORTANT:

• The saddle valve is not designed to regulate water flow; it is either open or closed.
• To prevent debris from clogging the solenoid inline filter, ensure the saddle valve handle is pointing toward the ceiling.

NOTE: Lightly clean the copper tubing ends with fine sandpaper before making any connections.

2. Use 1/4 in. O.D. copper tubing and connect the saddle valve to the inlet side of the solenoid valve.

CAUTION: Hazardous Voltage. Can cause personal injury or equipment damage. Do not use any line connected to an air conditioner.

1. Place the brass compression nut over the copper tubing.

NOTE: Do not over-tighten the compression nut. Moderate tightness prevents leaking.

2. Slide the brass ferrule over the tubing.
3. Insert the tubing into the solenoid valve fitting and support the valve while tightening the compression nut.

3. Connect a 1/2 in. (13 mm) drain tube to the humidifier drain fitting and run it to a suitable drain.

NOTE: Slope the drain tube downward for correct drainage.

Checking the Installation

Use the following procedure to check the humidifier installation:

1. Open the saddle valve.
2. Set the thermostat setpoint to 10°F (6°C) above the room temperature.

NOTE: The furnace blower must be on for the humidifier to operate.

3. Set the Convertible Humidity Control to a high setting, or place the H1008A Automatic Humidity Control in the Test position.
4. Observe water running out of the drain line to confirm the humidifier is working.
5. Check for leaks.
6. Reset the thermostat and Convertible Humidity Control to a comfortable setting, or the Automatic Humidity Control to the desired frost factor setting, for automatic operation.

Operating the Humidifier

The HE220A and HE260A Humidifiers are controlled by the Convertible Humidity Control, which is installed either on an interior wall in the living area or on the return air duct. Choose the humidity control setting using the combination relative humidity/outdoor temperature setting scale on the humidity control dial. Match the dial setting to the outdoor temperature for optimizing the humidity level while reducing moisture condensation on inside windows. Table 5 can also be used to adjust the humidity control to the recommended setting.

NOTE: As the outside temperature drops, the recommended setting is lowered to accommodate the effects of dewpoint. These settings should reduce the accumulation of moisture and ice on windows and in other areas of the house.

Some indoor activities (cooking, showering, clothes drying) can cause excessive humidity levels and lead to moisture accumulation on windows.

NOTE: If this condition persists for more than a few hours, set the humidity control to the lowest setting to turn off the humidifier. If the condition does not improve, ventilate your home to remove moisture.

The Honeywell HE220B and HE260B Humidifiers are controlled by the Honeywell H1008A Automatic Humidity Control with HumidiCalc+™ Software. This automatic humidity control is mounted in the return air duct, exposed to the air stream. The HumidiCalc+™ Software automatically adjusts the humidity level based on indoor temperature and humidity, inferred or measured outdoor temperature, and the frost factor dial setting. The frost factor accounts for variations in furnace size, window insulation, and average daily climate temperature.

The Automatic Humidity Control with HumidiCalc+™ Software requires an initial adjustment period. Set the frost factor dial to 5 and use Table 6 to adjust the frost factor, one setting at a time, increasing for more humidity or decreasing if moisture develops on inside windows. For more precise adjustment, set the frost factor between dial settings. Allow two days for the humidity level to stabilize before making further adjustments. Once the proper setting is found, HumidiCalc+™ Software takes over and makes future adjustments based on varying outdoor temperatures, maintaining optimal humidity and reducing moisture build-up on windows.

Table 5. Recommended Convertible Humidity Control Settings.

Table 6. Recommended Frost Factor Settings.

Operation

The HE220A,B and HE260A,B Humidifiers create vapor (evaporated water) when warm air blows over a water-soaked area. As the vapor circulates, relative humidity rises.

The humidity control monitors relative humidity and activates the humidifier accordingly. The humidifier has a water supply that disburses water over a humidifier pad. Warm, dry air from the furnace passes over the pad, collects moisture, and circulates it through the house.

Humidified air feels warmer and more comfortable, potentially allowing homeowners to lower the thermostat heating setpoint and save on heating fuel bills. The result is a more comfortable and energy-efficient home environment.

Maintenance

A regular maintenance program prolongs the humidifier's life and ensures a more comfortable environment. Either hard or soft water can be used. Cleaning frequency depends on water quality.

CAUTION: Voltage Hazard. Can cause electrical shock and equipment damage. Disconnect power supply before installing or servicing.

IMPORTANT: Never oil any part of the humidifier.
