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