4 . 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 STOP WARNING Risk of bodily injuries or pinching. Non observance may harm health or cause damage to product components. CAUTION Important note on functionality. Non observance of this note may cause malfunctions. Power supply 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. Technical constraints 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. Information Important operating advice and information. See another document. 99 See another page in the manual. 4 Underfloor Heating

5 2. The Uponor Control System The 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. Overview of the system The 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. 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 2 C position is marked. 2 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. 3 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 2 C position is marked. 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. Uponor Control System - Operation Manual 5 5

6 4 Controller with Thermostats and actuators 2.2 Operating your installation The 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 6-channel controller: The controller controls up to 6thermostats and 8actuators 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. 2-channel controller: 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. If your installation is equipped with this option, see the timer Manual for more information. The controller controls up to 2 thermostats and 4 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 2 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. 6 Underfloor Heating

Thermostat T-35 and Thermostat T Screw to open the thermostat Terminal for controller connection (non-polarized) Terminal for floor sensor (non-polarized) Set point temperature potentiometer Floor sensor potentiometer Heating / cooling demand LED (Opening / closing of the actuators) Room temperature setpoint dial control Terminal for controller connection (non-polarized) Terminal for floor sensor (non-polarized) Blue cam for setting minimum temperature Red cam for setting maximum temperature Floor sensor potentiometer Heating / cooling demand LED (Opening / closing of the actuators) Thermostat uses low voltage 6-2 volt.

8 3. Changing the temperature setpoint 3.2 Setting the min and max temperatures Thermostat T-35 and Thermostat T-37 Thermostat T-35 and Thermostat T-37 A red LED is lit during heating or cooling demand. 2 Rotate the dial clockwise to get a higher temperature setpoint Rotate the dial counter-clockwise to get a lower temperature set point Thermostat Public T 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 2 C. The setting of the blue cam is -0 C. The setting of the red cam is +5 C. The temperature range for this room is C to 26 C. There are no min and max temperature settings for the Thermostat Public. Select the required temperature using the potentiometer 8 Underfloor Heating

9 3.3 Floor sensor settings If 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 maintenance Checks 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. STOP Use a dry soft cloth to clean the Control System and all it's components. Do not use any detergent. Select the required temperature using the potentiometer See Installation manual for more information. Uponor Control System - Operation Manual 9 9

10 5. Diagnoses and resolution of faults Normal 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. General recommendations WARNING Note that some actions, e.g. actions involving 230V, wiring, etc., are to be performed by a qualified person. WARNING Risk of electric shocks. Disconnect the controller from the mains prior to any intervention. 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). 0 Underfloor Heating
