Example applications and possible configurations of the system are also included. 2.1 Safety instructions Warnings used in this manual The following symbols are used in the manual to indicate special precautions when installing and operating any Uponor equipment: WARNING! Risk of injury. Ignoring warnings can cause injury or damage components.
3 Description Uponor Control System Wired is a management system for underfloor heating and cooling installations. Comfort, userfriendliness and temperature control for each individual room of a home can be combined through the use of thermostats or floor temperature sensors. 3.1 3.2 Example of a system System overview Uponor Control System Wired consists of a controller, thermostats, actuators and an optional timer.
3.3 Uponor Control System Wired components Pos. Uponor designation Description A1 Uponor Controller, 6 Channels C-33 Wired 6-channel controller A2 Uponor Controller, 12 Channels C-35 Wired 12-channel controller B Mounting screws and plugs C Installation and Operation Manual Uponor Controller, 6 Channels C-33 Wired The Uponor Controller, 6 Channels C-33 Wired controls up to 6 thermostats and 8 actuators connected to the hydraulic system of the installation.
3.3.
3.3.4 Uponor Actuators Uponor actuators are mounted on top of the valves of the manifolds When the thermostat senses that the temperature has fallen below the setpoint, the controller sends a signal to the actuator to open the valve. The indicator window on the actuator turns bright. When the thermostat senses that the temperature has risen above the setpoint, the controller sends a signal to the actuator to close the valve. The indicator window on the actuator turns dark.
4 Installing the Uponor Control System Wired Installation procedure 2. Check that the connectors and switches are easily accessible. Uponor recommends that you follow the steps described below to achieve the best possible installation: CAUTION The Uponor Controllers C-33 and C-35 must be mounted horizontally. There is a risk for overheating if a controller is mounted vertically or on a horizontal surface. Section Description 4.1 Preparing the installation 4.
2. Press, without turning, with a thin screwdriver, on the white button of the quick connector. The controller senses automatically where the thermostats and the actuators are connected, this is called auto linking. 3. Insert a wire in the quick connector. Auto linking rules 4. Remove the screwdriver. In order to make the auto linking of the controller to work correctly, the following restrictions apply: 5.
4.3.3 Connecting thermostats and actuators to Uponor Controller C-33 Uponor Controller C-33 can only be used for heating. One to six thermostats and one to eight actuators can be connected to this controller. To connect the first thermostat with actuators to the controller, do this: Pos. Label Heating 4 Timer control zone 2 No cooling for this room Z2 Cooling NOTE! The two wires from the thermostat are non-polarized. Explanations to the different controller functions 1.
See section 4.4.4 Uponor Controller C-35 with four thermostats and timer for a connection example. 4.3.6 4. Open the lower lid (A) of the 230V compartment in the controller and fix it to the latch (B)on the upper part of the lid. Connecting a heating–cooling switch If the installation is equipped with a cooling unit, the Uponor Control System Wired can be run through a heating–cooling switch.
4. Open the lower lid (A) of the 230V compartment in the controller and fix it to the latch (B)on the upper part of the lid. • Thermostat #06 controls the actuator on channel 06 NOTE! The timer is not available for the 6-channel controller. NOTE! The economy mode (ECO) is not available for the 6channel controller. The installation will work in a standard way with the thermostats regulating each room according to their set temperatures. See also the wiring diagram on the foldout page. 5.
4.4.4 Uponor Controller C-35 with four thermostats and timer A connection example of Uponor Controller C-35 using four thermostats is shown in the figure below. NOTE! When connecting thermostats and actuators to the Uponor Controller, the auto-linking rules must always be followed strictly. See section 4.3.2 Auto linking, page 11 Any disregard to follow the auto linking rules will result in erroneous function of the Uponor Controller. 4.4.
Cooling mode • Thermostat #01 is connected to the (Common terminal) and Z1 connectors. The cooling will switch between comfort and economy mode according to timing pattern Z1. • Thermostat #03 is connected to the (Common terminal) and Z2 (cooling off) connectors. In cooling mode no cooling will be applied in this room. • Thermostats #05 and #12 are connected to the (Common terminal) and connectors (No timer control). Cooling is generated in comfort mode constantly.
4.5 Connecting the controller to AC power To conclude the installation of the controller: 1. Check that all wiring is complete and correct: • • • • • Thermostats Actuators Timer Heating–cooling switch Circulation pump 2. Ensure that the 230 V AC compartment of the controller is closed and the fixing screw is tightened. 3. Connect the power cable to a 230 V AC wall socket.
5 Installing thermostats The following thermostats can be connected to Uponor Control System Wired: • • • • • • Uponor Digital Thermostat T-36 Wired Uponor Programmable Digital Thermostat T-38 Wired Uponor Thermostat Flush T-34 Wired: Uponor Thermostat T-35 Wired: Uponor Thermostat T-37 Wired: Uponor Thermostat Public T-33 Wired: Analog thermostats • Uponor Thermostats T-34 and T-35: The temperature is adjusted with the dial.
5.2.3 Connecting thermostat to controller To connect the thermostat to the controller: 1. Insert the two wires of the thermostat cable into the connector terminals labelled 1 and 2. 2. Tighten the screws fixing the wires in the terminal block. 2. At the back of the thermostat, gently push the three guides (two indicated in the figure below) to separate the electronics part from the mounting frame. Connecting the cable to the controller is described in section 4.
5.4.3 Connecting thermostats to controller To connect the thermostat to the controller: 1. Insert the two wires of the thermostat cable into the connector labelled POWER. Connecting the cable to the controller is described in section 4.3 Connecting components to controller, page 10. 2. Tighten the screws fixing the wires in the connector. 5.
When the maximum temperature setting is used, the frost protection is also active. This means that the floor temperature will never fall below +5 °C. To set the floor sensor potentiometer: 1. Use a cross-headed screwdriver to set the potentiometer. See figure below. 5.4.4 Connecting optional floor sensor Uponor Thermostats T-33 and T-37 allow a floor sensor to be fitted to the system. The temperatures thus measured ensure a more efficient management of the system. Wiring the floor sensor 1.
6 Installing Uponor Timer I-36 for C-35 Uponor Timer I-36 for C-35 is a digital timer with three buttons on the front to adjust various timing functions. For instructions how to operate the thermostats, see section 9 Operating digital thermostats, page 26. 6.1 Opening Uponor Timer I-36 To open Uponor Timer I-36: 1. Gently press the tab at the bottom of the thermostat housing. 2. Lift off the top part from the mounting frame. Connecting the cable to the controller is described in section 4.
7 Finishing installation Make a complete check up of the installation: 1. Check that the thermostats are working correctly. Turn thermostat setpoints to maximum to obtain a heating demand and make sure that the actuators are running. 2. Reset the thermostats to the defined operating settings. 3. Close the covers of the controller and the thermostats. 4. Fill in the “Installation report” on the centre pages of booklet. 5. Give the manual and all information about the system to the user.
8 Operating Uponor Control System Wired The Uponor Control System Wired controls the floor heating/ cooling installation according to customer needs. Temperatures are adjusted with thermostats located in each room. 8.1 Principle of operation As soon as the temperature measured at a thermostat is lower (heating mode) or higher (cooling mode) than the setpoint temperature, it sends this information to the controller, which opens the actuators for this room.
