Additional Information

DEVIREG 535

TIMER AND THERMOSTAT

Floor sensor, room sensor or a combination of the two. devireg™ 535 is DEVI's latest model of a digital thermostat that contains all three functions in one. The functional thermostat is well suited for controlling the temperature in the entire house or in selected rooms. devireg™ 535 controls the heating extremely precisely regardless of whether the thermostat is to control the floor temperature, the room temperature or a combination of the two.

High precision
has developed a system called the Electronic Thermal Compensator or just ETC. devireg 535 is the first ETC programmed thermostat. This means that the thermostat can keep to the temperature required, regardless of the size of the room.

Better operation and child-lock
devireg 535 is pre-programmed with three programmes which match most people's need for heating control. The development department at DEVI has been working intensively with the development of a simple and user-friendly design which makes it easy to change the temperature as well as the time. This means that it is always possible to adjust the thermostat as the need for heat changes.

Low energy consumption – high capacity
DEVI's development engineers are constantly working on minimising energy consumption, and with devireg 535 they have succeeded in developing a thermostat with the market's lowest standby consumption of just 0.3W.

Furthermore, Devireg 535 has a 15 amp relay. This means that the thermostat can control the floor heating on areas as big as 34 m2 at 100 Watt per m2.

Reliable quality
As the world’s leading manufacturer of electrical floor heating systems, DEVI guarantees quality. devireg 535 is equipped with a two-pole safety switch, which interrupts the thermostat 100%. At the same time, DEVI’s Sensor Failure Monitoring safety system ensures that the floor heating is immediately interrupted if the sensor is interrupted or short-circuited.
