MAPS ® unit.
5.0 Electrical The energy recovery module does not require a separate electrical supply. Supply
and control wiring connections made when mating the module to the MAPS ® unit (See
illustration above.) are all that is required.
The electrical information on the MAPS ® unit rating plate includes MOP and MCA
requirements for the energy recovery module.

Controller
This IQ
Controller is
programmed
to control the
supply and
exhaust fans and
the wheel. It is
integrated with
the controller on
the MAPS ® unit.
MAPS ® unit has color-coded
connectors mounted in the wall
for connecting energy recovery
module control wires.
Energy Recovery Module electrical
compartment has openings where
wires with color-coded connectors
can be attached to the corresponding
connectors on the MAPS ® unit.

Module and MAPS ® Unit
(cont’d)
Connect the power supply
wires from the MAPS ® unit
to the distribution blocks.
(Refer to the unit wiring
diagram.)
All energy recovery modules have a unit-mounted, IQ controller
that is programmed to control all system components located
in the energy recovery module. This includes the energy recov-
ery supply fan, energy recovery exhaust fan, and the enthalpy
wheel. The controller is programmed as an integrated section
of the main MAPS ® unit. Once the MAPS ® unit and the energy
recovery module are connected in the field, the controllers
automatically connect and start sharing information between
systems. All information from the energy recovery module is
shared with the main MAPS ® unit IQ controller. This allows for
unit and the energy recovery module to act as a complete sys-
tem and to respond to all sensors installed in both components.
This also allows one access point for all information and opera-
tional data.
Outside Air or Outside and Return Air Dampers
There are three airflow configurations available on a MAPS ®
unit with an energy recovery module (see below). Options AR2L
and AR2K with motorized dampers are identified on the unit
wiring diagram. The outside air damper is always opened prior
to operation of the MAPS ® unit blower and the energy recovery
module fans. The return air damper (AR2K) is interlocked with
the outside air damper.
Control NOTES:
A change in protocol or baud rate on the main MAPS ® unit
controller requires a matching change on the energy recovery
module controller.
For more detailed information on controls, refer to the
MAPS ® system control manual. The IQ technical manual,
Form CP-MAPS D15/16/17/18, is included with the MAPS ®
unit and is also available at www.RezSpec.com.
