User guide 1.0 Basics • The Devireg™ 550 thermostat controls electrical floor heating elements using a built-in and/or external temperature sensor. • The Devireg™ 550’s adaptive function automatically optimises the unit for the room within a few days after installation and continuously collects updated room data. This means improved performance (with compensation for e.g. sudden temperature drops in the room) and precise timing so the selected temperature is achieved at exactly the right time.
User guide 1.2 Functional Overview Timer on Child lock on Frost protection on Temperature below set value Display Hour display Clock setting active Degree symbol Weekday display Timer setting active Button The thermostat is operated by using the button as follows: Turning clockwise or counter-clockwise to raise or lower values, e.g.
User guide 1.3 Temperature Setting Operation without timer: • The hour display appears as an unbroken ring with a blinking dot indicating the current time (if set). Raise or lower the temperature. • The set temperature appears on the display. • The system maintains the set temperature 24 hours a day. • If the thermostat uses a floor sensor only, the display shows the set temperature on a scale from 1 to 10. • If you lower the temperature to +5 °C, appears on the display.
User guide 1.5 Operating the child lock Press and hold the button. INT While holding, turn steadily counter-clockwise, until “COdE” appears on the display. Turn clockwise to select “0033”. Press to confirm. or appears on the display. • The child lock is on.

When the timer is on: • appears on the display. • The hour display shows the set comfort temperature periods for the current day as black segments of dots. • The current day is shown on the weekday display. • The system automatically switches between comfort and economy temperatures at the preset times of day. • The economy temperature never appears on the alphanumeric display.
User guide 2.1 Optional Settings 2.1.1 Setting the time and weekday INT Press and hold for 3 seconds. appears on the display. Set the correct time. • A small dot on the hour display shows the currently set time. • When the set time passes 0:00 in either direction, the weekday display changes to the next or previous day (depending on which direction the button is being turned). Press to confirm. disappears from the display. 2.1.2 Setting the timer Press and hold for 6 seconds. appears on the display.

Set the duration of the first comfort temperature period. • The duration is shown as a segment of black dots on the hour display. Press to confirm.
User guide • You have now defined the starting time, duration, and ending time of the first comfort temperature period. • Repeat as required to define subsequent comfort temperature periods. • When the set time passes 0:00 in either direction, the weekday display changes to the next or previous day (depending on which direction the button is being turned). In this way it is possible to program an entire week with different comfort and economy temperatures for each day.
User guide Set the minimum floor temperature. Press to confirm. The display returns to normal. • The floor temperature is kept above the set lower limit. 2.2 Troubleshooting • In case of an error, the hour display starts flashing and the weekday display indicates an error code from 2 to 7. • Refer to the description of error messages in section 6 of the Installation Manual. • If the system does not function correctly, call a qualified electrician. 2.
Installation manual 1.0 Installation overview 1.1 Safety instructions • Make sure the mains supply to the thermostat is OFF before installation. If the thermostat is installed in a network, the INT mains supply to ALL thermostats in the network must be off! • As the Devireg™ 550 is not equipped with an earth terminal, the earthing screen of the heating cable and the earthing wire from the mains supply must be connected to the earth terminal in the surface mounted box or recessed metal box.
Installation manual 1.2 Installation guidelines • Dismantle the thermostat before installation and observe the following guidelines: Place the Devireg 550™ at a suitable height on the wall. In wet rooms, the thermostat should be installed on an even surface according to local building regulations. Place the thermostat at least 50 cm from windows/ doors that will be left open occasionally. Do not place the thermostat on a wall where it will be exposed to direct sunlight.
Installation manual 2.0 System overview 2.1 Three different sensor configurations FS: Floor sensor (comfort heating) • Suitable for floor heating in e.g. bathrooms. The built-in room sensor is not used. • Comfort heating should be used only to supplement a regular room heating system. INT RS: Room sensor (total heating) • Suitable for control of room temperature in e.g. living rooms. Unsuitable for wet rooms. • The thermostat must be mounted in the same room as the heating elements.
