Section 2
System Functionality
The Climate Co˘ntrol - Multifunction hydronic controller is built to handle
various mechanical functions and operates based on how the user sets up
the software through the display module.
The following describes Climate Co˘ntrol's functionality:
Boiler Operation
The boiler res until it reaches a maximum temperature during
commissioning. The temperature of the primary loop drops until the
temperature approaches the boiler's target temperature, which is determined
by what part of the system is calling for heat.
Boiler Protection (optional setting)
Climate Co˘ntrol - Multifunction unit monitors the return boiler temperature.
If the temperature drops too low, the system will begin to close the threeway valves. If this option doesn't work, the high-temperature pumps will
shut down.
Domestic Hot Water (DHW)
Domestic Hot Water (DHW) function is controlled and operated through
either a sensor or aquastat (switched) input for a single-tank installation.
Zone Pump Control
The system integrates zone pump operation, which controls unused ports
within the Climate Co˘ntrol - Multifunction unit.
Mixing
Up to three independent water temperatures for either space heating or
snow melting can be mixed, accomplished through either a valve or injection
pump. (Uponor recommends using a valve.)
Snow Melting
Climate Co˘ntrol - Multifunction system provides heat to melt snow and ice.
If boiler protection is needed, the system will reduce the heat output of the
snow-melt system.
www.uponor-usa.com • www.uponor.ca

Uponor Climate Co˘ntrol™ - Multifunction Installation Guide
5
Semi-automatic Control
Heat is supplied to the snow-melt slab for periods of time specied by
the user:
• Slab Delta T — Used when ramping up the snow-melt slab
temperature. The system limits the water temperature to the slab to
prevent the Delta T from exceeding a maximum temperature.
• Slab setpoint — The system will cease to apply heat once the slab
setpoint is reached.
• High outdoor temperature limit — Snow melting is disabled when
the outdoor temperature exceeds a determined value.
• Low outdoor temperature limit — Snow melting is disabled when
the outdoor temperature drops below a determined value.
• Maximum water temperature — This is the maximum water
temperature the system supplies to the slab.
Fully Automatic Control
When the snow and ice sensor detects snow and ice, the system applies heat
in the same manner it does under semi-automatic control. The difference is
that the system will not stop until the snow and ice detector is clear of ice
and snow and the run timer expires.
Slab Idle
The slab idle setting allows the slab to maintain a set temperature.
High Temperature
If the control supports high-temperature control, the system will turn on
the high-temperature pump until the demand call ends. However, if the
minimum boiler-return temperature is approached, the high-temperature
pump may be turned off to reduce the load on the boiler.
Pump Exercising
After seven days of not operating, a pump or three-way valve will
automatically turn on for two minutes and then automatically turn off.
Section 3
Safety Measures
Important: Failure to follow the instructions and installation
steps in this guide can result in the failure of the Climate Co˘ntrol
- Multifunction system.
• Read the instructions. Do not make changes or modications specied
in this guide. Uponor is not responsible for damages and breakdowns
that may result from not adhering to these instructions.
• Installation must be performed by a qualied installer according to
local codes and regulations.

The display and main control are packaged as a single unit, assembled and
pre-wired for operation. Uponor recommends mounting the main control
panel in the mechanical room or near the mechanical equipment it will
operate to eliminate any unnecessary wiring.
These tools and hardware are necessary for installation:
• Screws and/or anchor hardware for mounting
• Flathead and Phillips screwdrivers
• Wire cutters/strippers
• Level
• Thermostat wire, 18/2 AWG for connecting sensors
• Cat5 wire for connecting pumps, valves or boiler
• Cat5 cable stripper (optional, but recommended if making custom cables)
• Cat5 cable tester
Mounting the Control Panel
1. Select a smooth, at, uniform surface.
2. Select the proper screws and/or anchors for the
surface. Four screws or anchors will properly
secure the unit.
3. Remove the side wings of the main control by
loosening the four screws on the control unit.
This will expose holes necessary to mount to
the selected surface.
4. Install the rst screw semi-tightly so the control
can be rotated. (See Figure 4-1.)
5. Level the control prior to installing any
additional screws. Mark the location with
a pencil or pen if anchors are being used.
(See Figure 4-2.)
6. Install the remaining screws to nish mounting
the control.
Optional Control Panel Mounting
7. Remove the display cover if it is necessary to
secure the panel. (See Figure 4-3.)
8. Apply downward pressure and pull the bottom
of the display away from the backing by placing
a thumb on the bottom of the display and
ngers on the display's top.
9. Use the access holes in the back of the
panel to secure to the wall or surface.
(See Figure 4-4.)
10. Replace the front enclosure.
Connecting Mechanical
Devices to the Controller
The layout of the wiring connections makes for
a quick and simple installation. All connections
on the control's right side are made to boilers,
pumps, modulating valves and snow melt using
RJ45 connectors and a Cat5 cable. Once the
cable is available and tested, it plugs into the
connector on the control's right side and
clicks into place to secure the connection.
(See Figure 4-5.) The connection can easily
be changed or moved by pressing down on the
latch and disconnecting from the control.
The top two ports on the control's right side are
reserved for boilers. If a second boiler is not part
of the mechanical system, the second port can
be used for any other device.

The control's left side has inputs using push-style connectors, so the use of
a small tip screwdriver is not required. (See Figure 4-6.)
These connectors require dry-contact inputs from
switching relays, thermostats or any other similar
devices. The bottom four connectors are fully
programmable outputs.
When active, LEDs for the inputs and outputs
will turn green.

Boiler Connections
When connecting to boilers or any type of heating devices that require
an input or signal to start, an Uponor Boiler Control (A9012010) is required.
This boiler control provides two dry contact outputs and B terminals.
Terminal A is typically wired to start a heating device and is connected to
the Climate Co˘ntrol - Multifunction controller using the proper-length Cat5
wire with RJ45 connectors. (See Figure 4-7.)
The boiler relay comes with a set of LEDs to show the status of the device.
The A and B lights will turn red when the Multifunction Climate Co˘ntrol
unit turns either of the relays on for heat. The green LED will illuminate
when the relay box is connected correctly to the Climate Co˘ntrol Multifunction unit. A manual override switch for each set of terminals
(A and B) is located inside the cover. These will operate when the relay is
not connected to the control via a Cat5 cable.

Multiple Boiler Stages
The Climate Co˘ntrol - Multifunction controller can run multiple boiler stages
(up to four) to optimize and regulate the proper amount of heat based
on outdoor temperature and loads. (See Figure 4-8.) As the temperature
differential increases between the supply and return sensors, the Climate
Co˘ntrol - Multifunction system will turn on an additional boiler. As the
differential decreases, the controller will turn off and rotate usage of the
boilers to ensure that the run time on each is equal.

Modulating Condensing Boilers
When there is a call for heat, the A terminal on boiler controls calls on
modulating (modcons) boilers. The Climate Co˘ntrol - Multifunction unit
cannot override the boiler settings through the A terminals. However, most
modcons allow a second input for domestic hot water (DHW) or other
high-temperature requirements. In these types of installations, the
B terminals on the boiler control provide that function. (See Figure 4-9.)
Note: Consult the boiler manufacturer’s installation and wiring instructions
to verify the high-temperature override.

Modulating Valves and Mixing
The Climate Co˘ntrol - Multifunction controller provides mixing and water
temperature control in secondary piping for lower temperature applications,
such as radiant oor heating and snow melting. The Climate Co˘ntrol hydronic
controller can connect to any 0-10VAC motor and valve using the Uponor
Modulating Valve Control (A9063020).
Note: The motor must be 75 milliamps or less from a 24VAC supply or it
must be externally powered.
The Climate Co˘ntrol - Multifunction unit supports up to three separate water
temperatures, any combination of three for space heating and up to two
maximum for snow melting. Supply-and-return Dual Sensors (A9013001) are
plugged into the valve box using a Cat5 cable. (See Figure 4-10.) The ports
are not dedicated so any connection port can be used for connecting sensors
and cable to the Climate Co˘ntrol - Multifunction unit. These 10K sensors are
strapped or mounted to the secondary piping for temperature data to set the
proper position of the valve, based on outdoor temperature, load
requirements, etc.

The valve relay comes with a set of LEDs to show the relay's status.
Terminal strips for wiring connections to the valve motor and a manual
switch are contained inside the cover. The manual switch, when set to the
Man position, overrides any control signal coming from the Climate Co˘ntrol Multifunction controller and allows the installer to set the valve position.
Caution: Failure to return the manual switch to the auto position
will affect the correct regulation of secondary water temperatures.
When the valve box is connected properly to the control, the
power light turns green. The active light turns red whenever the
control is changing the position of the valve for mixing.
The Climate Co˘ntrol - Multifunction unit supports variable speed injection
mixing, which requires an Uponor Pump Relay Box (A9013030). (See Pump
Connections below for additional information on wiring.) Uponor promotes
the use of modulating valves rather than injection pump valves due to lower
power consumption and staying in line with the industry as it moves toward
modulating and condensing boilers.
Pump Connections
Climate Co˘ntrol - Multifunction unit supports on/off operation of pumps
(maximum of three amps) in a variety of applications. Common types of uses
include primary, secondary and domestic hot water (DHW) pumps. As an
added feature, the Climate Co˘ntrol - Multifunction hydronic controller can
be congured to run zone pumps on open or spare ports.
All pumps are quickly and easily connected using Cat5 cables. The Pump
Relay Box comes with LEDs to show the status of the relay. When the relay
and the pump are wired correctly, the auto light will turn green when power
is applied to the circuit. When the system turns on the pump, the Call and
On lights will turn green. A manual switch is included under the top cover
of the relay. When this switch is set to the manual position, the On light will
turn green, provided the auto light is on. When set to the manual position,
the manual switch overrides any control signal coming from the Climate
Co˘ntrol - Multifunction controller and allows the pump to run continuously.
(See Figure 4-11.)
Caution: Failure to return the manual switch to the auto position
can lead to overheating.

Snow-melt Connections
Climate Co˘ntrolTM - Multifunction supports snow-melt operation through
the Uponor Snow Melt Control (A9013051). The Snow Melt Control, which
wires to the main control panel using a Cat5 cable and RJ45 ends for simple
and easy connections, can plug into any port other than what is reserved
for boiler connection. This basic snow-melt package allows for slab sensing
to control the slab temperature for melting. (See Figure 4-14.) An active
red LED is included on the snow-melt control to indicate when the area is
heating. A manual button is also included to start a melting cycle if the idle
feature is not used. Terminals are optional when a remote-mounted switch or
button is required outside of the mechanical room or area.

Section 5
Setting-up Functionality
This section helps the user understand this
control's full power and exibility.
Application-specic controls inform the user
which devices to connect. Uponor has reversed
this. Climate Co˘ntrol - Multifunction, the most
versatile control in mechanical-room functionality,
allows the installer to tell the control which
devices are connected and which functions to use.
If a port has already been set up for a function,
the menu displays that function in addition to
Clear Port Function. At this point, clear the port
for a new function or press the left to go back
and select an unassigned port. The user can press
clear at any time to begin the selection
process again.
Setting-up Boiler Functionality
The Climate Co˘ntrol - Multifunction unit comes with pre-loaded software
to run and operate up to four boiler stages. As noted earlier in this guide,
Ports 1 and 2 are always dedicated for boiler connections. If only one or two
boilers are being controlled, only Port 1 is used and Port 2 is available for
other functions. If two boilers require the Climate Co˘ntrol - Multifunction
hydronic controller to have one boiler with a DHW override, then both Ports
1 and 2 are required for that operation. See Multiple Boiler Stages on
page 13.
Note: If a heating plant is self-contained — where it controls itself
without any external demand — ports are not assigned or reserved
for boiler operation.
To access the port assignment menu, follow this
path: Uponor Screen > Settings > Ports > Port 1
> Boiler Properties >. (The use of the > symbol
indicates pressing the OK button.)
