Preface

The Uponor Control System Installation and Operation Manual describes how to install and operate the components of the system.

Conventions used in this manual

The following symbols are used in the manual to indicate special precautions when installing the Uponor Control System:

WARNING Risk of injury.

Ignoring warnings can cause injury or damage

components.

CAUTION Ignoring cautions can cause malfunctions.

Safety measures

Read and follow the instructions in the Installation and Operation Manual.

Installation must be performed by a competent person in accordance with local regulations.

It is prohibited to make changes or modiﬁ cations not speciﬁ ed in this manual.

Power

WARNING The Uponor Control System uses 50 Hz 230 V AC power.

In case of emergency, immediately disconnect the power.

Limitations for radio transmission

The Uponor Control System uses radio transmission. The frequency used is reserved for similar applications, and the chances of interference from other radio sources are very low.

However, in some rare cases, it might not be possible to establish perfect radio communication. The transmission range is sufﬁ cient for most applications, but each building has different obstacles affecting radio communication and maximum transmission distance. If communication difﬁ culties exist, Uponor can support the system with accessories, such as repeaters, for solving exceptional problems.

Technical constraints

• To avoid interference, keep installation/data cables

away from power cables for more than 50 V.

• The electrical circuits of the boiler and the pump

must be protected by a circuit breaker rated at 6 A or below.

Disposal

The Uponor Control System consists of various recyclable components. Uponor would be grateful if the components (batteries, plastics, and electric or electronic parts) are sorted and disposed of at a suitable recycling centre.
