Field Wiring
Once all the ducts are installed and the wires for the controllers are connected, the HRV/ERV
may be connected to a standard 120V power outlet with ground. Unit comes with 3’ cord.
Receptacle must be used. DO NOT USE AN EXTENSION CORD.
If further wiring is required, have a licensed electrician make all electrical connections. It is
recommended that a separate 15 amp/120 volt circuit be used.

Installing the Digital Multifunction Control (P/N 611242-FC)
The Digital Multifunction Controller is an advanced wall control that offers the user many
different ways of operating the HRV/ERV, including an Automatic mode that uses a high-
accuracy, fast reponse humidity sensor to remove excess humidity from the home.
The Digital Multifunction Control (P/N 611242-FC) can be
used with any type of Aldes Residential HRV/ERV. The controller
should be installed in the place where excess humidity is most
likely to be detected, for example near a bathroom, kitchen
or in the basement. Ensure good air circulation around the
controller. Do not place it behind a door, for example.
Please refer to the controller’s documentation for detailed mounting and operating
instructions. Note that the Automatic dehumidistat mode is intended to be used when the
outdoor air has less moisture content than the indoor air. Turn off the Automatic mode when
outdoor air is hot and humid.
