Honeywell H46C1166 Dehumidistat Control

The H46C1166 Humidity Controller is used with portable and central unit dehumidifiers to maintain relative humidity.  The H46C has an spst snap acting switch designed for line voltage circuits and two lead wires for switch box mounting.

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 series.

Wiring in parallel allows the dehumidistat to independently control the humidity level, but could cause over-cooling 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 over-cooling, 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.
