APPLICATION
The EPHUM24 controls a dehumidifier or dehumidification system to help prevent mildew build-up, which is
associated with high humidity levels.
The controller is designed to be wall-mounted and can be wired in parallel or in series with any 24V thermostat.
PARALLEL INSTALLATION
ADVANTAGES:
The desired humidity is always maintained, regardless of the ambient temperature.
DISADVANTAGES:
The connected system could cycle on during low ambient temperatures.
Not all dehumidifiers can operate at low temperatures.
Note:
DO NOT USE parallel wiring if there is no low temperature compressor protection is not present.
SERIES INSTALLATION
ADVANTAGES:
The connected system will not cycle on during low ambient temperature periods.
DISADVANTAGES:
The humidity levels may be higher than desired during low temperature periods.
INSTALLATION INSTRUCTIONS
1. Disconnect the electrical power.
2. Determine the location for the dehumidistat location. This control should be mounted on an inside wall where
normal air circulation exists. For most residential useage applications, locate mount the control adjacent to the
existing wall thermostat, for easy installation and wiring.
3. Remove the cover from the back plate and punch remove the wiring knockout on back plate.
4. Place the back plate on a flat mounting surface and mark 2 mounting hole locations, and wire knockout hole.
