Introduction

Thank you for buying our MCD3 thermostat.

We hope you will enjoy the ease of use oered by

the well-known user interface and design.

This high-quality thermostat has a minimum impact on

the environment by design and will at the same time

provide you with long-lasting heating comfort.

The thermostat switches on your ﬂoor heating

at preset times each day of the week.

The thermostat is preset with up to four events for

each day of the week. Lowering the temperature

when your home is unoccupied reduces your

energy costs without reducing comfort.

The thermostat comes with preset heating

schedules adjustable to your speciﬁc needs.

A temperature setting range from 0°C to 40°C and an

external override function ensures your comfort and

protects your property.

This thermostat can be used as a controller for electric

room heating pursuant to EN50559.
