Heat Recovery Ventilator Control
The Heat Recovery Ventilator (HRV)
Control (A9011200) manages an
HRV with up to three fan speeds:
low, medium and high, depending
on the manufacturer of the installed
equipment. A single Uponor Climate
Cŏntrol™ Network System can include
up to eight HRV Controls.
Getting Started
2. After unclipping both legs, slide
the clear cover to the right.
Mounting the Unit
The HRV Control typically mounts on
or near the HRV it controls. Use the
following instructions to mount the
control properly.
Caution: Before performing
any wiring, disconnect the
electrical power to the
system to prevent electrical
shock and damage to the
The package includes:
Note: Ensure all wiring complies with
local electrical codes. Uponor
recommends 18 AWG LVT or
similar wire for all terminal block
connections to the controlled
equipment and the power
source. Strip all wires to 1/4”
(6.3 mm) to ensure proper
connection to the terminal blocks.

Tools and Parts Required
The Uponor Climate Cŏntrol Network
System HRV Control supports most
HRV brands. Refer all HRV Controlrelated issues for this installation to
Uponor Technical Support, regardless
of your HRV brand.
Check the contents of this package.
If the contents are damaged, please
contact your Uponor sales representative
or distributor for assistance.
1. Remove the cover by gently pulling
the cover legs on the left of the case.
3. Use #6 screws in the three
mounting holes to fasten the
control as shown in Figure 1.
• RJ45 crimper and connectors
• Cable tester
• Wire cutter and stripper
Mounting Holes
• Small-blade screwdriver
Figure 1: Location of
Mounting Holes
• Three #6 mounting screws and
appropriate screwdriver
For speed selection, you can configure
outputs for the HRV Control as:
• Standard dry-relay contacts
• A mixture of 3.9K ohm resistive and
dry-contact inputs
Refer to Table 1 in configuring
the HRV Control for various HRV
Note: If your HRV is not listed in
this section, contact the HRV
manufacturer to determine
which type of output is
required to control your unit.

Configuration Notes
These units require dry-relay
contacts. Insert jumper J1A into
the Lifebreath + Constructor
position as shown in Figure 2.

1.5, 2.0
Figure 4: HRV Wiring Applications
Refer to Figure 4 for wiring schematics
to connect the HRV Control to various
heat-recovery ventilators.
Figure 2: Lifebreath +
Constructor Position
These require a dry contact for
high speed and a 3.9k resistive
contact for low speed; insert
jumper J1A into the Other
Venmars position as shown in
Figure 3.
Note: The AVS Solo is an
example of this setup.
The main control cabinet supplies
power for the HRV Control via
the Cat5e network cable. The 24V
power terminals require a separate
24V power supply when a CO2/VOC
(carbon dioxide/volatile organic
compound) sensor is connected to the
HRV board.
Network and Main
Panel Wiring
On the right side of the HRV board,
a Cat5e cable connects to the Field
Modules (ports) of the Router Main
This cable may also connect to a
Network Y-Connector when more
than one HRV board is installed in the
network system (in a “daisy-chain”
The following devices may be combined
with a Network Y-Connector:

Venmars Position
Table 1: HRV Configuration Notes
Note: All screw terminals used for
connecting power and devices
are blocks and can be removed
from the board. This feature
allows you to disconnect wiring
temporarily without the need
for remaking the connections.
• Furnace Air Handler Control
• Heat Recovery Ventilator Control
• Zone Valve Damper Control
• General Input Output Control
Note: Total length of Cat5 cable in any
daisy-chain configuration should
not exceed 500 feet. Refer to
Appendix A in the Uponor Cŏntrol
Network System Manual for
more information about wiring
field device networks.
Optional CO2 /VOC Sensor
You can add an optional CO2/VOC
Sensor (A9010201) to the system to
monitor the CO2 and VOC levels in the
ventilated space.
Important: The CO2/
VOC Sensor can not be
used in the Climate Cŏntrol
Network System without
the HRV board.
This sensor connects to the HRV
Control either via the Cat5e connector
on the top edge of the control or the
terminal blocks.
If connecting the CO2/VOC sensor to
the Cat5e connector, supply 24VAC,
6 VA power to the black power
connector on the left side of the
control. Run a single pair of 18 AWG
LVT wire from a 24VAC source to the
HRV Control. If connecting the sensor
to the terminal blocks, supply 24VAC,
6 VA power directly to the sensor.
Refer to Figure 5 and Figure 6 for
the two wiring options.
Wiring Option 1:
C02 – VOC Sensor
Unit Number Jumper
The Unit Jumper indicates the
network address for each HRV to a
unique jumper position (address)
between 1 and 8 (see Figure 7).
Note: Do not set multiple HRV controls
to the same number as this
causes unpredictable operation.
Figure 5: Hardwire CO2/VOC Sensor Wiring
Figure 7: Unit Number Jumpers
Manual Jumpers
With Manual Jumpers, the installer
can configure the manual operation of
the control’s outputs.
Wiring Option 2:
Note: You cannot configure the low
output. It stays on continuously
when the Manual switch is in
the MAN position.
Cat5 Cable
C02 –
VOC Sensor
If another manual speed jumper is
set to on, both the low output and
the jumper’s respective output will
activate. In most HRVs, a signal for
mid or high speed will override the
low output signal, and the HRV will
run at the desired speed.
In Figure 8, the low and high outputs
will activate when the Manual switch
is in the MAN position.

Figure 8: Manual Switch
and Jumpers
Manual Switch Operation
The Manual switch offers an advantage
in situations when the system is not
completely set up or when the power
to the Router Main Control is off.
Select the MAN position on the
Manual switch to run the HRV in
manual mode.
Auto Position
The AUTO position allows the Uponor
Climate Cŏntrol Network System to
control the HRV Control outputs.
Manual Position
The MAN position turns the fan output
on as well as any outputs whose manual
jumpers are set in the ON position.
Off Position
The OFF position forces all the
outputs on the control off.
Indicators and Specifications

outputs. These
indicators illuminate
when their respective
outputs activate.
