SAFETY CONSIDERATIONS

Installing, starting up, and servicing equipment can be haz- ardous due to system pressures, electrical components and equipment location (roofs, elevated structures, etc.). Only trained, qualified installers and service mechanics should install, start up, and service this equipment.

When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attached to the equipment.

Before installation, always check to be sure main power to systems are OFF. Electrical shock can cause personal injury or death.

GENERAL

The MDEH1 dehumidistat is used with Totaline SHR series heat recovery ventilators. See Fig. 1. The dehumidistat is used to control the indoor humidity level. High humidity is a major

cause of structure damage and IAQ problems such as mold and mildew.

INSTALLATION

NOTE: For technical assistance, call 1-800-747-1762.

To install the dehumidistat, perform the following procedure:

1.Determine the mounting location for the dehumidistat. Location should be in an easily accessible area. Do not locate where humidity sensor could be affected by direct humidity sources.

2.All controls are low voltage. Use 22 to 26 gage field- provided wire.

3.Connect two wires to the DEHUM terminals on venti- lator. See Fig. 2. Polarity does not matter. Either wire can be connected to either terminal.

4.Run wire to mounting location. Do not run control wire with power wiring. Interference from power wir- ing can cause changes to control signal.
