CAUTION

Electrical Shock Hazard.

Can cause electrical shock or equipment damage.

Disconnect power supply before connecting wiring.

Location

Select a location about 5 ft (1.5m) above the floor in an area with good circulation at average temperature and humidity for the area to be controlled. Avoid locations near hot or cold air ducts and discharged air from the controlled equipment.

Wiring

Mounting

1.Remove the setting knob.

2.To remove cover, pull cover forward from device.

3.Install a 2 in. x 3 in. (51 mm x 76 mm) vertical switch box at the selected location.

4.Using the two screws provided, fasten the adapter plate to the switch box, as shown.

Disconnect power supply before connecting wiring to avoid electrical shock or equipment damage. All wiring must comply with local codes or equipment damage. All wiring must comply with local codes and ordinances. Do not exceed contact and coil ratings when wiring into system. See Fig. 2.

Connections and Operation

A dehumidistat in combination with the thermostat can be used to run the air conditioner to control relative humidity levels. The dehumidistat and thermostat can be wired in parallel or in series.

Wiring in parallel allows the dehumidistat to indepen?? dently control the humidity level, but could cause overcooling of the home. During unoccupied times, the homeowner should set the thermostat to a relatively high setting and control moisture using the dehumidistat.

Wiring in series prevents overcooling but the air conditioner runs only when both the thermostat and dehumidistat are calling. During unoccupied times, the homeowner should set the thermostat to a relatively low setting and control moisture using the dehumidistat.

SETTING AND ADJUSTMENT

The H46 makes contact on a relative humidity rise to the setpoint to start the dehumidifier. On a decrease in relative humidity to the setpoint (minus the differential), the switch breaks contact to stop the dehumidifier. Turn the knob clockwise to the setting stop to place the H46 in the On position. Turn the knob counterclockwise to the setting stop to place the H46 in the Off position.

CHECKOUT

After completing all mounting and wiring, turn on the power supply. Place the system into operation by turning the setting knob toward the low end of the scale until the dehumidifier motor starts. Turn the setting knob slowly toward the high end of the scale until the dehumidifier motor stops.
