Section 1
The Climate Co˘ntrolTM -
Multifunction System
System Overview
Uponor introduces Climate Co˘ntrol™ - Multifunction, the industry’s rst
control systems platform that supports all functions required in today’s
heating control systems.
With user-friendly wiring and setup, which allows for optimal installation
through an easy-to-use display, Climate Co˘ntrol - Multifunction's standard
functionality and operation include:
• Boiler staging and rotation
• Domestic hot water (DHW) operation
• Water-temperature mixing
• Automatic or slab-sensing snow melting
• Optional zone pumping
Climate Co˘ntrol - Multifunction's architecture supports up to eight
outputs (e.g., pumps, modulating valves, boilers). The unused ports can
support additional zone pumps within the system rather than adding
other control elements.

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.

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.
• Always turn off power when performing any wiring functions
or connections.
• The Climate Co˘ntrol - Multifunction system uses a 24VAC/50VAC/60Hz
power supply. In case of an emergency, immediately disconnect the
power from the controller.
• Keep sensor cables away from power lines greater than 50VAC to avoid
interference.
• Do not use water to clean the controller. Do not expose the controller to
ammable vapors or gases.

Climate Co˘ntrol -
Multifunction Installation
Before installing the Climate Co˘ntrol - Multifunction unit, verify the package
contents with the following list:
• Installation guide
• Main control panel
• Outdoor sensor
• Supply and return sensor (or dual sensor)
• Data key (mounted inside display enclosure)
Important: Read the following installation instructions prior
to installing the display and main control. It will prevent any
unnecessary rework.

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.
