INSTALLATION OF THE HEAT ASSIST OPTION
IF YOU PURCHASED YOUR UNIT WITH THIS OPTION: THE MAKE-UP AIR UNIT AND CONTROLLER COME
FULLY ASSEMBLED AND CONFIGURED SO THE FOLLOWING INSTRUCTIONS NEED
NOT
BE DONE, although
we include them here anyway.
The Additional Air Inlet Selector (AIS) module (see image)
should come with a 10 foot molex and a temperature
harness to connect the controller to the module. The AIS
can be installed in either position before the filter box
module. This gives you some freedom to adapt to your
installation situation and the only thing you’ll have to
keep an eye on is that the controller harnesses are
connected to the correct AIS module.
This Heat Assist module (AIS-2) allows you to (re)use the
heat in your attic to (re)heat the living space and has an
inlet grille which should be free enough to properly
breathe. The interface settings allow you to dial in this
functions for your installation.
If you purchased this module separately It will have to be installed into the Make-Up Air unit system. The
module is designed to be quickly “clicked” onto the another module with brackets, guiding plates and
quick-lock clips. For this to be done with ease the entire unit has to be removed to create access and allow
you to lock the brackets (see image) into the other module while you hold the new module at an angle. It
might be possible to add it, with the MUA installed. These brackets lock behind the rim of the module you
are installing. It will become clearer if you inspect an already assembled module. The AIS Module can be
mounted in multiple orientations to fit your needs.
After you have physically installed the
Module it has to be connected
to the controller with the supplied
Molex Harness (AIS-2) and strain relief.
Open the controller by removing
the lid. This is accomplished by
loosening the 4 lid screws and
sliding the lid upward until it can
be removed.
Install the AIS-2 harness as shown
in the image and connect the molex
connector to the actuator on the
AIS-2 you just installed
Install the Power jumper (shunt) onto
JP4 to supply power through the relay
to the actuator.
