DEVIreg™ 535 1.2 Safety Instructions Make sure the mains supply to the thermostat is turned off before installation. IMPORTANT: When the thermostat is used to control a floor heating element according to "Household and similar electrical appliances - Safety - EN/IEC 60335-1 : General requirements" and "EN/IEC 60335-2-96: Particular requirements for flexible sheet heating elements for room heating ", always use a floor sensor and never set the maximum floor temperature to more than 35°C.
DEVIreg™ 535 2 Mounting Instructions Please observe the following placement guidelines: Place the thermostat at a suitable height on the wall (typically 80-170cm.). The thermostat should not be placed in wet rooms. Place it in an adjacent room. Always place the thermostat according to local regulation on IP classes. Do not place the thermostat on the inner side of an exterior wall. Always install the thermostat at least 50 cm. from windows and doors.
DEVIreg™ 535 Do not place the thermostat in a way that it will be exposed to direct sunlight. Note: A floor sensor enables a more accurate temperature control and is recommended in all floor heating applications and mandatory under wooden floors to reduce the risk of over-heating the floor. ▪ Place the floor sensor in a conduit in an appropriate place where it is not exposed to sunlight or draft from door openings. ▪ Equally distant and >2cm from two heating cables.

To accept the new selected temperature, press •. 4. Press installation button D to configure settings. devireg™550 D 5.
DEVIreg™ 535 Note: Please contact the floor supplier before changing the maximum floor temperature and be aware of the following: ▪ The floor temperature is measured where the sensor is placed. ▪ The temperature of the bottom of a wooden floor can be up to 10 degrees higher than the top. ▪ Floor manufactures often specify the max temperature on the top surface of the floor (usually 27-28˚C). ▪ Always use a floor sensor or a room + floor sensor combination to control floor heating.
DEVIreg™ 535 How to define the temperature scale Special condition: If floor sensor is selected, the numerical scale with steps from 1 - 6 must be selected. Note: By default, the Celsius scale is used. 1. To change the default temperature scale, press the • button. 2. Select a scale, use the ▲▼ buttons.
