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.

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.

Outdoor Temperature Sensor
The TS3 outdoor temperature sensor is required for dual fuel
heat pumps. The wiring hub automatically switches to fossil fuel
heating when the outdoor temperature drops below the OBP,
Outdoor Balance Point temperature. The temperature limit can
be changed using Installer Option 03 (see T32 or T32WF
manual).

USING WIRELESS SENSORS
Before installing the wireless remote temperature sensor, the ER1
Electronic Receiver Module needs to be installed in the Wiring
Hub.
Install the ER1 Electronic Receiver
!
Warning!
Do not turn power on until AFTER the wireless sensors have
been installed and the sensor numbers set, as shown in the
following steps. The Wiring Hub will automatically detect the
electronic receiver and the sensors being used when powered
up.
The ER1 Electronic Receiver plugs into the two 6-pin terminal strips
on the H32 Wiring Hub.
ER1 Electronic Receiver
The outdoor temperature sensor should be placed in a shaded
location and protected from rain or snow such as under the
eves of a home. Select a location and drill a 5/16-inch
diameter hole to pass the sensor wires through.
Use 2-conductor, 18 or 20 gage, thermostat cable to wire
from the H32 Wiring Hub to the outdoor temperature sensor.

Install Remote Wireless Sensors
The TSER is wireless and powered by two AA
batteries. Two remote temperature sensors can
be used and the temperatures are averaged. For
a single sensor installation, install the sensor on
an interior wall about 4-feet above the floor and
in a location that best senses the upstairs
sleeping area temperature.
For a dual sensor installation, install the sensors
in locations that will best sense the average
upstairs sleeping area temperature, such as the
master bedroom and the bedroom hallway.
Mount the TSER subbase using the screws
provided.
Install two AA batteries as shown.

Setting Wireless Sensors as #1 or #2 Using the TSRC Wireless Bedside Control
The TSER is factory set as #0 wireless temperature sensor and
must be set to #1. If two temperature sensors are used, set the
address number on the second sensor to #2. The sensor
location needs to be documented for future reference. Use the
removable labels included with the wireless sensor to identify
the sensors as #1 or #2. Place the labels on the front of the
thermostat over the battery cover.
Press the push button and the LED will blink once, then twice
and repeat this pattern. To set the sensor as the #1 sensor,
release the push button switch after one blink or after two blinks
to set it as #2 sensor. After releasing the push button, the LED
will blink yellow once to indicate successful communication or
blink red indicating that communication was not successful.
The TSRC can be used to turn Econo
Cooling (ECool) On of Off. The TSRC
can be wall mounted or can sit on a
bedside table.
When the Econo Cool mode (ECool) is
turned On, the installed whole house fan
or Economizer will be activated using the
timer or temperature control.
The TSRC is battery powered and
requires no wiring.

Selecting a Different Home Number
When two or more wireless EvenAir installations are within 300feet of each other, the EvenAir thermostat and remote wireless
temperature sensors must be set to different Home numbers so
they do not interfere with one another.

Remove one of the batteries to remove power to the sensor.
While pressing the push button switch on the sensor, re-install

then three rapid blinks and so on. Release the switch after the
number of blinks corresponding to the Home number to be set.
Changing the Home number does not affect the assignment as
the #1 or #2 sensor (1 to 8).
Remote Wireless Bedside Control
If a TSRC bedside control is used to control the ECool mode
for a whole house fan or economizer, the Home number in the
TSRC must be set to same home number selected in the

MAINTENANCE AND TROUBLESHOOTING
THERMOSTAT OPERATION
Problem - nC is displayed on thermostat.
nC is displayed on the thermostat when the thermostat loses
communication with the wiring hub. If the message continues
to be displayed, turn the system off and check the wiring
between the thermostat and wiring hub.
DAMPER OPERATION
Problem - No airflow to the sleeping area AND living
area registers
Turn system off immediately. Both dampers may be connected
backwards at the wiring hub or at the damper actuator (causing
dampers to close rather than open).
Problem - No airflow to the sleeping area OR living
area registers
Turn system off. One of the dampers may be connected
backwards at the wiring hub or at the damper actuator
(causing a damper to close rather than open).
Problem - Limited airflow to the sleeping area OR living
area registers
Turn system off. The damper blade movement may be inhibited.
To verify a damper blade moves freely, remove the two
mounting screws on the actuator. Do not disconnect the plug
and play cables. Verify the damper blade spins 360 . If the blade
spins freely, reattach the actuator to the damper by aligning the
keyed shaft. If the blade does not spin freely, examine the
damper for obstruction or damage and replace the damper if
necessary.
o
SENSOR INSTALLATION
Problem - nS message on thermostat.
For wired sensors, check that the sensor is wired correctly.
Check for a short in the sensor wiring. For wireless sensors,
check that batteries are installed in the sensor and that the
sensor numbers are set correctly.
Problem - Err 01 or Err 02 message on thermostat.
Check the batteries in the wireless sensor and that the
sensor numbers are set correctly.
Problem - Sleeping area temperature reading very high or
very low.
Check that the correct sensor(s) have been used. One
wired TS51 sensor is used in a single sensor installation.
Two TS52 sensors are used in a dual sensor installation.
Problem - When directing airflow to the sleeping area, the
airflow is actually directed to the living area, and when
directing the airflow to the living area, the airflow is actually
directed to the sleeping area.
Turn system off. Check if the dampers are switched (sleeping
area damper is connected to the living area connector and the
living area damper is connected to the sleeping area connector.)
COMFORT CONCERNS
Problem - Downstairs bedroom is too cold or too hot at night.
The Nighttime Airflow Control option directs more airflow to the
sleeping area and less airflow to the unoccupied living area. If
the downstairs bedroom is on the same HVAC trunk as the
living area, the downstairs bedroom may become uncomfortable
at night. Turn off the Nighttime Airflow Control option using the
User Options.
Problem - The room temperature on the thermostat seems
too high or too low.
The thermostat is factory calibrated within 1 degree.
However, if a homeowner finds the temperature “feels”
too high or too low, the thermostat can be calibrated to
what the homeowner feels is the correct temperature using
Installer option 15 for the living area and option 16 for
the sleeping area.
