1 Introduction

DEVIreg™ 534 is an electronic timer temperature controller,specially designed for floor heating systems. The thermo-stat is provided with a combination of a floor sensor and aroom sensor to measure and control the desired floor androom temperature. It can be either flush-mounted or sur-face-mounted.

Once set, the thermostat will automatically adjust the heatto meet your comfort requirements by measuring the floortemperature and combining it with the measured air tem-perature regardless of changing weather conditions.

1.2 Safety Instructions

Make sure the mains supply to the thermostat is turned offbefore installation.

Please also note the following:

▪ The installation of the thermostat must be done by anauthorized and qualified installer according to localregulations.

▪ The thermostat must be connected to a power supplyvia an all-pole disconnection switch.

▪ The sensor is to be considered as live voltage. Havethis in mind if the sensor must be extended.

▪ Always connect the thermostat to continuous powersupply.

▪ Do not expose the thermostat to moisture, water, dust,and excessive heat.

2 Mounting Instructions

Please observe the following placement guidelines:

Place the thermostat at a suitable heighton the wall (typically 80-170cm.).

DEVIreg™ 534


The thermostat should not be placed inwet rooms. Place it in an adjacent room.Always place the thermostat according toNFC15100 - part 7-701.

Do not place the thermostat in a way thatit will be exposed to direct sunlight.

Note: A floor sensor enables a more accu-rate temperature control and is recom-mended in all floor heating applicationsand mandatory under wooden floors toreduce the risk of over-heating the floor.

▪ Place the floor sensor in a conduit in an appropriateplace where it is not exposed to sunlight or draft fromdoor openings.

▪ Equally distant and >2cm from two heating cables.▪ The conduit should be flush with the floor surface -

countersink the conduit if necessary.▪ Route the conduit to the connection box.▪ The bending radius of the conduit must be min 50mm.

The screen of the heating cable must be connected tothe earth conductor of the power supply cable by us-ing a separate connector.

Note: Always install the floor sensor in a conduit in thefloor.

3. Mount and reassemble the thermostat.

▪ Fasten the thermostat to a socket or an exterior wallbox by driving the screws through the holes in eachside of the thermostat.

▪ Tighten the screws to fasten the thermostat.

4. Turn on the power supply.

Initially main supply the thermostat for 15 hours to fullycharge the battery. The current time and day is then keptfor 80 days if mains supply is off. All other settings are stor-ed permanently.

3 Settings

Sensor: How to specify whether an external floor sen-sor, the built-in room sensor or both is used to controlthe floor heatingNote: The floor sensor option is selected by default.

2. Press the • button.

3. Select one of the following options using the ▲▼buttons:

If only a floor sensor is used, choose:The built-in room sensor is not used.This option is suitable for rooms inwhich a constant floor temperature isrequired, e.g. in a bathroom.

If both a room sensor and a floor sen-sor is used, choose:This option is suitable for all roomsbut wet rooms. The thermostat mustbe installed in the same room as thefloor sensor and the heating elements.

DEVIreg™ 534


If only a room sensor is used, choose .This option is not recommendabledue to an increased risk of overheat-ing the floor. The thermostat must beinstalled in the same room as theheating elements.

4. To accept the new selected sensor mode, press •.

5. Press installation button D to configure settings.

6. If you have chosen the floor sensor or room/floor sen-sor option, press ▲▼ (up/down) buttons to continueto the next setting.

How to set the maximum floor temperatureSpecial condition: This setting only applies if a floor sensoris used (the floor sensor or room/floor sensor option hasbeen set).Note: The maximum floor temperature is set to 28°C bydefault.

1. To change the default temperature setting - press the• button.

2. Select the new temperature by using the ▲▼ but-tons.

3. To accept the new selected temperature, press •.

5. Press ▲▼ (up/down) buttons to continue the nextsetting.

Note: Please contact the floor supplier before changing themaximum floor temperature and be aware of the following:

▪ The floor temperature is measured where the sensor isplaced.

▪ The temperature of the bottom of a wooden floor canbe up to 10 degrees higher than the top.

▪ Floor manufactures often specify the max temperatureon the top surface of the floor (usually 27-28˚C).

▪ Always use a floor sensor or a room + floor sensorcombination to control floor heating. Without a floorsensor, the temperature control may be less accurateand you risk overheating the floor.
