Chapter 1 System overview The Uponor Climate Control Zoning System II is for use with underfloor heating installations and combines comfort, user friendliness and temperature control for each individual room of a home. The system consists of a base unit, thermostats and actuators. The base unit manages the operation of the actuators when the thermostats detect a demand for the heating. The system is controlled by different types of thermostats.
Base unit Components The base unit operates the actuators, which in turn affect the flow of the supply water, to change the indoor temperature using information transmitted from registered thermostats and system parameters. D Up to six channels and eight actuators can be operated by the base unit, which is typically located near the radiant manifolds. The radiant illustration below shows the base unit with the antenna and actuators.
Thermostats Digital thermostats The thermostats communicate with the base unit through radio transmissions and can be used individually or in combination. All the thermostats use AAA batteries. Main characteristics Important! The thermostat is affected by the temperature of the surrounding surfaces as well as the ambient air temperature.
Expansion module PWM control Main characteristics PWM control is used when the Autobalancing function is active. • Adds six channels and actuator outputs to an existing base unit When installing a system with PWM control, the system is balanced automatically.
Chapter 2 Installation setup Installation procedure Installation preparation Uponor recommends following the process described below to guarantee the best possible installation results. Before starting the installation: Step • Verify the contents of the package with the packing list. • Check whether an external temperature sensor is to be installed with a compatible thermostat.
Installation example Option A The figure below shows an installation example of the base unit (six channels) with an optional expansion module (six extra channels) using thermostats and actuators. • External temperature sensor • Floor temperature sensor Option B Thermostats will regulate each room according to their set temperatures. • Outdoor temperature sensor • Thermostat 01 controls the actuators on channels 01a, 01b, 02a and 02b with an optional AC sensor.
Chapter 3 Installing the base unit Placement Attaching and detaching components • Position the base unit just above the manifold, ensuring 24 VAC, 50 VA power is available. The components can either snap on or off without having to remove the covers. • Check that the cover of the base unit can be easily removed. • Check that connectors and switches are easily accessible. Modular placement The base unit is designed with the option of modular placement in mind.
Attaching the antenna to a wall The antenna can be attached to the right-hand side of the base unit or to the wall. If the base unit is installed inside a metal cabinet, the entire antenna must be placed vertically outside the cabinet, as illustrated below. The illustration below shows the antenna attached to a wall with screws (A) or double-sided adhesive strips (B).
Attaching the base unit to a wall Screws and wall plugs The base unit is delivered in a kit that includes screws, wall plugs and a mounting bracket. The figure below shows base unit mounting hole positions and how to attach it to the wall using screws and wall plugs. Mounting brackets Attach the mounting bracket to the wall using the screws and wall plugs, then attach the base unit to the mounting bracket.
Removing the expansion module Connecting components to the base unit The illustration below shows how to remove the expansion module from the base unit. Refer to the wiring diagram found at the end of this document. The illustration below shows the inside of the base unit. 1.2 A mm B D G H m 8m 1 C E F B A 2 Figure 3-11: Connecting components to the base unit Figure 3-10: Removing the expansion module 1.
Connecting actuators to the base unit Connecting a circulation pump to the base unit Each thermostat can control one or more channels. To simplify installation and maintenance, Uponor recommends that actuators controlled by the same thermostat wired in sequence to the channels. R/T A3010100 W/T A3080301 Connect the actuators to the base unit as follows. 1. Lead the cables from the actuators through cable entries in the bottom of the base unit frame (see Figure 3-12).
Connecting a boiler (optional) 4. Route the wires from/to the boiler via a cable entry. The controller includes a boiler relay that can be used to send a signal to either fire the heat source or to open a two-port motorized zone valve positioned on the flow to the underfloor heating manifold. If the relay is used to open a zone valve, the dry contact on the zone valve should be used to fire the heat source. 5. Connect the boiler to the connection labeled BOILER.
Testing actuators It is possible to manually open or close an actuator connected to a channel when testing the system. Testing an actuator takes about 10 minutes and the base unit automatically returns to run mode when finished. 1 2 Important! Activated test/cycle mode for a channel is indicated with a lit LED, when in forced mode. Refer to the instructions below to test the actuators. 1. Enter test/cycle mode by pressing the > button while in run mode. 2. Use the < or > buttons to select a channel.

Chapter 4 Installing thermostats and sensors The following thermostats can be connected to the system: Inserting batteries • Wireless Dial Thermostat (A3800165) All thermostats use two alkaline 1.5 V AAA batteries which provides about two years of battery life, as long as they are positioned within radio range of the base unit. Ensure the batteries are correctly inserted into the thermostats.
Digital thermostats Using a wall bracket (recommended) The external temperature sensor input can be used for either a floor, outdoor or remote temperature sensor. Use the software on the thermostat to select a control mode which corresponds to the use of the sensor and thermostat. The illustration below shows thermostat mounting hole positions and how to attach it to a wall using a wall bracket.
Attaching to a table stand Temperature setpoint The illustration below shows how to attach the thermostat to a table stand. The thermostats are delivered with a default setpoint of 70°F (21°C). The illustration below shows how to adjust the thermostat temperature setpoint.
Registering thermostats in the base unit 1 2 1. Press and hold the OK button on the controller until the LED for channel 1 (or the first unregistered channel) flashes red. 2. Use buttons < or > to move the pointer (LED flashes red) to a preferred channel. 3. Press the OK button to select the channel for registration. The LED for the selected channel starts flashing green. 5. Select a thermostat. ds on ec Note: Uponor recommends registering all channels to the thermostat at the same time.

Chapter 5 Operating the base unit The Climate Control Zoning System II controls the underfloor heating installation according to customer needs. Sequence of operation As soon as the temperature measured at a thermostat is lower (heating mode) than the setpoint temperature, a demand to change the room temperature is created and sent to the controller. The controller will open the actuators according to current operating mode and other settings.
Unregistering all channels When one or more channels are inaccurately registered, it is possible to remove all registrations at the same time. Caution: Make sure the base unit is in run mode. Refer to the instructions below to cancel all channel registrations. 1. P ress and hold the OK button on the base unit until the LED for channel 1 flashes red/green, or the first unregistered channel flashes red. 2.
Chapter 6 Operating dial thermostats Thermostat components Adjusting the temperature During normal operation, if there is a demand for heating, a descreet LED on the dial thermostat is lit for about 60 seconds. The temperature is changed by adjusting the setpoint on the thermostat to a value between 41°F to 95°F (5°C to 35°C). A C F D E Use the dial on the thermostat to adjust the temperature. A backlight will light up when twisting the dial. It shuts off after about 10 seconds of inactivity.
Factory reset Important! Do not factory reset the thermostat if not absolutely needed. A factory reset removes the registration data from the thermostat. 2 3 1 4 A3800165 Figure 6-4: Factory reset instructions Refer to the following instructions to factory reset a dial thermostat. 1.
