Made in USA

The EvenAir H32 wiring hub is installed at the equipment. It is connected to the T32 or T32WF
thermostat using the existing or new 4-wire thermostat cable that normally connects the thermostat
to the equipment. The equipment is wired directly to the Wiring Hub, The upstairs sensor can be
either a wired or wireless sensor. Wireless sensors require the ER1 radio module that plugs into the
wiring hub. An outdoor temperature sensor can also be used to control fossil fuel heating in a dual
fuel heat pump or to control a whole house fan or economizer.

The EvenAir wiring hub can be used to control humidification and de-humidification, fresh air
intake per ASHRAE 62.2, ERVs or HRVs, whole house fans and economizers.

COMPONENTS:

READ THESE INSTRUCTIONS CAREFULLY AND COMPLETELY BEFORE PROCEEDING WITH THE INSTALLATION.

MODULATING DAMPERS

Round or rectangular dampers using the AMJ plug and play
actuator and up to 1 inch static pressure. Up to 6 dampers can
be daisy chained to define the upstairs sleeping area or
downstairs living area.

WIRED TEMPERATURE SENSORS

One TS51 or two TS52 temperature sensors can be used in the
sleeping area.

WIRELESS TEMPERATURE SENSORS

One or two TSER wireless temperature sensors can be used in
the sleeping area. The ER1 radio module must be installed in
the wiring hub when wireless sensors are used.

INSTALLATION

i

Homes with plaster walls with steel lathe may
experience wireless communication interference
when using wireless sensors. Wired sensors are
recommended under those conditions.

!

CAUTIONS

Before installing the EvenAir comfort system, turn off
all power to your HVAC system.

INSTALLER

5)

Check for Start Up Messages/Errors.

6)

Set equipment options 1-6 if different than factory
default settings. (see T32 or T32WF manual).

7)

Test the installation by initiating a heating call, cooling
call and fan call.

8)

Install batteries and set the time and day (see T32 or
T32WF manual).

Read and follow all instructions carefully.

Read entire manual before installing EvenAir products.

Follow all local electrical codes during installation. All
wiring must conform to local and national electrical
codes.

Use cautions when mounting components to surfaces
that may have concealed wiring beneath the surface.

When servicing EvenAir system or accessing products,
turn off all power to these items.

i

ATTENTION INSTALLER

1)

Install and wire components to the wiring hub.
(See Wiring Diagrams section).

2)

If wireless sensors are used, install the ER1 electronic
receiver module in the wiring hub and set the sensor
number and home number as necessary.

3)

Place the thermostat on the subbase. Do not install
batteries. (See T32 or T32WF manual).

4)

Turn power to the HVAC equipment On.

Refer to T32 or T32WF manuals for accessing:

Airflow Control Off Option 50 turns off Airflow Control.
The thermostat controls the system, dampers fully open,
nighttime airflow control is disabled and airflow is no
longer displayed on the thermostat.

User Airflow Control can be enabled using Option 52
User turns off automatic airflow control in the User
Options.

Nighttime Airflow Control is defaulted to ON. If
bedrooms are located downstairs, consider turning this
option Off using the User Options if bedrooms are not
on the same trunk.

Fresh Air Control is defaulted to Off and controlled by
Options 20 thru 25.

Whole House Fan or Economizer Control is defaulted
to Off and controlled by Options 30 thru 34.

Humidifier and De-Humidification Control is defaulted
to Off and controlled by Options 40 thru 42.

Airflow Control is defaulted to On and controlled by
Options 50 thru 57.

ATTACH THE H32 TO THE WALL

Attach the H32 at the equipment to a solid surface as shown
using the screws and wall anchors supplied.

INSTALLER

INSTALL UPSTAIRS & DOWNSTAIRS DAMPERS

Install a modulating damper in the duct supplying air to the
upstairs sleeping area and plug one end of the cable into the
connector marked IN on the AMJ actuator and the other end into
the connector marked SLEEP DAMPER on the Wiring Hub. Install a
second modulating damper in the duct supplying air to the
downstairs living area and plug one end of the cable into the
connector on the AMJ actuator marked IN and the other end into
the connector on the Wiring Hub marked LIVING DAMPER. Each
damper uses 2.4VA of power.

When two or more dampers are required to define the upstairs or
downstairs areas, the second damper may be plugged into the
connector marked OUT on the first damper. Up to 6 dampers
can be connected to define an area. LEDS on the damper
actuator indicate when the damper is fully open (green) or fully
closed (red).

Ensure that damper installation does not cause

!

obstruction to the damper blade.
