4 Underfloor Heating

1. General recommendations

Safety measures• Read and follow instructions.

• Installation must be performed by a qualified person according to local regulations.

• It is prohibited to make changes or modifications not specified in this manual.

• Power must be switched off when carrying out the wiring.

• We decline any responsibility concerning damages and breakdowns that may result from the non-observance of these instructions!

Symbols used in this manual

Power supply

Technical constraintsWARNINGRisk of bodily injuries or pinching.Non observance may harm health or cause damage to product components.

STOP

CAUTIONImportant note on functionality. Non observance of this note may cause malfunctions.

InformationImportant operating advice and information.

See another document.

WARNING

• The Uponor Control System uses a 230VAC 50Hz power supply.

• In case of emergency, immediately disconnect the plug from the 230V mains.

• Do not use water to clean the Uponor Control System.

• Do not expose the Uponor Control System to flammable vapors or gases.

• Keep installation/data cables away from power cables > 50V to avoid interference.

• The electrical circuits of the boiler and the pump must be protected by a maximum 6A circuit-breaker.



2. The Uponor Control SystemThe Uponor Control System is a complete management for underfloor heating systems. Comfort, user-friendliness and temperature control for each individual room of your home can be combined through the use of thermostats or floor temperature sensors.

2.1 Overview of the systemThe Uponor Control System consists of thermostats, a controller and actuators. The controller manages the operation of the actuator when the thermostats detect a demand for heating or cooling.

The Uponor Control System may be controlled with the help of three types of thermostats. Designed for maximum comfort, the thermostats communicate with the controller by non polarized two wired system. It's possible to use all kinds of Uponor Control System wired thermostats in the same system.

Thermostat T-35 wired

Thermostat T-35 is easy to use.Temperature settings are be adjusted with a dial.The dial must be removed to set min/max on the thermostat.The 21°C position is marked.

Thermostat Public T-33 wired

The thermostat is for public location. The potentiometers are hidden by a cover. The cover may be removed to allow min/max temperatures to be set. This thermostat also can be used to connect a floor sensor option.

Thermostat T-37 wired for floor sensor

Thermostat T-37 is easy to use.Temperature settings are be adjusted with a dial. The potentiometers are hidden by a cover. The dial and the cover must be removed to set up min/max on the thermostat. This thermostat also can be used to connect a floor sensor option. The 21°C position is marked.

2.2 Operating your installationThe Uponor Control System controls your heating installation according to your needs. You simply have to set the temperatures you wish on the thermostats located in each room.

Principle of operation:As soon as the temperature measured at the thermostat is lower than the desired set temperature, it sends this information to the controller, which opens the actuators for this room. Once the set temperature is reached, fresh information is sent and the actuators are closed.

Normal operation without optional timer

When the system is running in normal mode:In Heating mode, the actuators are open when room temperatures are lower than the temperatures set on the thermostat.In Cooling mode, the actuators are open when room temperatures are higher than the temperature set on the thermostat.The actuator position can be seen in the small windows of the actuators.

Operation with optional timer Comfort / Economy features

The use of a timer (option) optimises the installation and conserves energy.

Controller with Thermostats and actuators

6-channel controller:

The controller controls up to 6 thermostats and 8 actuators connected to the hydraulic system of the installation.The controller drives the actuators according to the information received from each thermostat and according to the system parameters settings.The controller is typically located near the hydraulic system manifolds.The window in the actuator shows when a valve is open or closed.

12-channel controller:

The controller controls up to 12 thermostats and 14 actuators connected to the hydraulic system of the installation.The controller drives the actuators according to the information received from each thermostat and according to the system parameters settings.The controller is typically located near the hydraulic system manifolds.The window in the actuator shows when a valve is open or closed.

Several extensions can be added on to the 12 channels controller:

• A timer can be used to add energy saving features and to define the independent zones.

• If your installation is equipped with a cooling unit, the Uponor control system can be run through a heating / cooling relay.

If your installation is equipped with this option, see the timer Manual for more information.

3.2 Setting the min and max temperatures


A red LED is lit during heating or cooling demand.

Rotate the dial clockwise to get a higher temperature setpoint

Rotate the dial counter-clockwise to get a lower temperature set point

Select the required temperature using the potentiometer

Remove the dial with a screwdriver

Set the minimum temperature with the blue cam

Set the maximum temperature with the red cam

The blue and red cam set the lower and upper ranges from which the set temperature is allowed to deviate.Example:

• The usual set point is 21°C.

• The setting of the blue cam is -10°C.

• The setting of the red cam is +5°C.

➜The temperature range for this room is 11°C to 26°C.

There are no min and max temperature settings for the Thermostat Public.

3.3 Floor sensor settingsIf your system includes a floor sensor, a potentiometer fitted on the Thermostat Public T-33 and Thermostat T-37 allows you to adjust the minimum or maximum temperature settings for the floor.The floor sensor can be used for maximum or minimum limitation of the floor temperature, regardless of the room temperature.For example, the maximum limitation will protect a sensitive floor covering from exposure to too high temperature when there is a high heat demand. The minimum limitation can keep a tiled floor warm even when there is a no general demand for heat supply to the room.

4. System maintenanceChecks on your system components regularly to optimize performance. This system requires no maintenance.

Automatic exercise function:

The system is fitted with an automatic exercise function. Set every 6 days +/- 24 hours, this function consists of a test-run designed to prevent the pump and actuators from seizing up, when they have not been activated since the last test.

Select the required temperature using the potentiometer

See Installation manual for more information.

STOPUse a dry soft cloth to clean the Control System and all it's components. Do not use any detergent.



5. Diagnoses and resolution of faultsNormal system operating conditions:

The Power LED of the controller is lit up. The actuators are activated if there is demand for heating or cooling.

5.1 General recommendations

To contact your installer:

See the Installation report in the fold-out to find the contact information for the Installer.

Please prepare the following information before contacting an installer:

• Installation report.

• Drawings of the underfloor heating system (if available).

WARNINGNote that some actions, e.g. actions involving 230V, wiring, etc., are to be performed by a qualified person.

WARNINGRisk of electric shocks. Disconnect the controller from the mains prior to any intervention.
