Caution: To avoid interference, keep installation/data
cables away from power cables of more than 50 VAC.
Limitations for radio transmission
The Uponor Climate Control Zoning System II uses radio
transmission. The frequency used is reserved for similar
applications, and the chances of interference from other radio
sources are very low.
However, in some rare cases, it might not be possible to
establish perfect radio communication. The transmission
range is sufcient for most applications, but each building has
different obstacles affecting radio communication and maximum
transmission distance. If communication difculties exist, Uponor
recommends relocating the antenna to a more optimal position
and ensuring radio sources are at least 16" (40 cm) apart for
solving exceptional problems.

System overview
The Uponor Climate Control Zoning System II is for use
with underoor heating installations and combines comfort,
user friendliness and temperature control for each individual
room of a home.
The system consists of a base unit, thermostats and actuators.
The base unit manages the operation of the actuators when
the thermostats detect a demand for the heating.
The system is controlled by different types of thermostats.
Designed for maximum comfort, the thermostats communicate
with the base unit by radio link. It is possible to mix the
different types of thermostats in the same installation.

Uponor actuators
Uponor actuators are mounted on top of the manifold valves
and operated using either on/off signals or pulse width
modulation (PWM) signals.
On/off control
When installing a system with on/off control, manual balancing
of the system is required.
As soon as the temperature measured at a thermostat is lower
(heating mode) than the setpoint temperature, a demand to
change the room temperature is created and sent to the base
unit. The base unit will open the actuators according to current
settings. Once the set temperature is reached, this information
is sent and the actuators are closed. The indicator window on
the actuator shows, with a white bar, how much it is opened.
If the window is completely lled with white it is fully opened,
no white bar shown means the actuator is closed.
Figure 1-9: Actuator valve status
A Actuator has closed the valve (empty indicator)
B Actuator has opened the valve (white indicator)
Autobalancing
The base unit can operate the actuator outputs by either on/off
signals or by Autobalancing (on by default), using PWM signals.
Autobalancing is a function where the system calculates the
actual energy need of single rooms and adapts the output
power of each loop to its length. This means a short loop
might get 20% on time while a long loop might get about 60%.
The automatic balancing continues through the seasons
and throughout the household’s changing lifestyle and
usage patterns, removing the need of manual balancing.
This gives more even oor temperatures and faster system
reaction times with lower energy consumption than any
standard on/off system.
Low hysteresis temperature
Uponor uses a low hysteresis temperature for best performance
of the system. It is used for high-control accuracy by deciding
when to start and stop heating and cooling, based on information
from sensors and setpoint values.
MicroSD card
The system uses a microSD card for cloning automatic backup
(settings and thermostat registration data), manual restoration
of backup, data logging (room data, controller data, system data
and events) and upgrading software.
Time to open and close an actuator is one minute.

Connecting a boiler (optional)
BOILER
The controller includes a boiler relay that can be used to
send a signal to either re the heat source or to open a
two-port motorized zone valve positioned on the ow to
the underoor heating manifold. If the relay is used to open
a zone valve, the dry contact on the zone valve should
be used to re the heat source.
Alternatively, the boiler relay can be used to send a demand
signal to the water temperature controller. The additional
contacts on the water temperature controller should then be

Installing thermostats and sensors
The following thermostats can be connected to the system:
• Wireless Dial Thermostat (A3800165)
• Wireless Digital Thermostat (A3800167)
Thermostat placement
Refer to the following guidelines when positioning
the thermostats:
1. Select an indoor wall and a distance 5 ft. (1.5 m)
above the oor.
2. Ensure the thermostat is away from direct solar radiation.
3. Ensure the thermostat will not be heated through the wall by
sunshine.
4. Ensure the thermostat is away from any source of heat
(e.g. television set, electronic equipment, replace, spotlights).
5. Ensure the thermostat is away from any source of humidity
and water contact.
6. Ensure the thermostat is positioned at least 1.3 ft. (40 cm)
away from the controller to avoid interference.
Inserting batteries
All thermostats use two alkaline 1.5 V AAA batteries which
provides about two years of battery life, as long as they are
positioned within radio range of the base unit. Ensure the
batteries are correctly inserted into the thermostats.
After inserting the batteries, the thermostat will perform a
self test for about 10 seconds. The system will block for input
and the thermostat LED ashes during this period.
The illustration below shows where to insert the batteries.

Figure 4-1: Thermostat placement
Labeling thermostats
Label the thermostats, where suitable, with the channel
numbers they are to control (e.g. 02, 03). For a system
with several controllers, add the ID of each controller
(e.g. 1.02, 1.03, 2.02, 2.03).
If the thermostat can connect to an external sensor,
add information about sensor type when applicable.
Available thermostat and sensor combinations:
• Room temperature
• Room and oor temperature
• Room and outdoor temperature
• Remote sensor temperature
Important! For accurate temperature, attach the

Maintenance
Manual preventive maintenance
The system requires no preventive maintenance except
cleaning with a dry, soft cloth.
Warning! Do not use any detergents to clean
the Climate Control Zoning System II.
Automatic preventive maintenance
The system is equipped with an automatic exercise function
that consists of a test run designed to prevent the pump and
actuators from seizing up due to inactivity.
This exercise is run every six days ±24 hours at random.
• The pump exercise operates only if the pump has not been
activated since the last exercise. The pump is activated for
3 minutes during the exercise.
• The actuator exercise operates only if the actuators have not
been activated since the last exercise. The exercise consists
of opening and completely closing the actuators periodically.
Corrective maintenance
Fallback mode
If a thermostat is malfunctioning or not detected, the controller
executes the fallback mode to maintain the temperature in the
room until the problem is resolved.
Resetting the controller
If the controller does not work as expected, for example
due to a hang-up, it can be reset to solve the problem.
1. Disconnect and reconnect the controller to AC power.
Controller LEDs
Uponor recommends occasionally checking the power
LED on the controller for alarms. The power LED ashes
continuously for general alarms. Determine which thermostats
are issuing alarms by removing the cover. If a channel
LED is indicating an error, check the function and batteries
of the registered thermostat.
The controller power LED is on during normal operation.
All the channel LEDs are off when there is no current or
waiting actuator activity. The LEDs turn on when the
corresponding actuators are activated or start ashing
when they are awaiting activation.
The illustration below shows the position of the controller LEDs.

Contact the installer
For installer contact information, refer to the installation report
at the end of this document. Prepare the following information
before contacting an installer:
• Installation report
• Drawings of the underoor heating system (if available)
• List of all alarms, including time and date
Installer instructions
To determine if a problem is caused by the supply system or
the control system, loosen the actuators from the manifold for
the room concerned, wait a few minutes and check if the ow
pipe of the underoor heating loop becomes warm.
If the pipe does not become warm, the problem is in the
heating system. If the loop becomes warm, the cause could
be the room control system.
A supply system defect can be indicated by no warm water
in the manifold. Check the boiler and circulation pump.
