devireg™ 550. The thermostat that thinks!
devireg™ 550 is a fully programmable 7 day combined timer and thermostat.

The thermostats' in-built intellgence continually learns from its environment, and is able to calculate the pre-heat period accordingly on a daily basis. For example, if the thermostat is set to achieve 22ºC at 7am, the devireg™ 550 will calculate the exact time the heating should be turned on to reach this temperature. During the year it will contine to adjust itself to suit changing climatic conditions - winter v summer..

The pro-active devireg™ 550.
devireg™ 550 uses a sophisticated, unique regulator which enables it to work actively with comfort parameters, room temperature and economy, in order to improve on comfort and at the same time, save on energy.

When the outdoor temperature drops, any thermostat controlled heating system will react by compensating for the greater heat loss by increasing the floor temperature. devireg™ 550 however, is programmed to understand, that if the floor temperature is higher, the air temperature can be lowered a little - for the same comfort level. So, if the floor temperature is increased by +1°C, the air temperature will be decreased by -0,2°C, thus saving up to 10% energy compared to ordinary thermostats.

Network Control
You can also set up your devireg™550 controlled heating system as a network. Then you can control all thermostats by either a Master devireg™ 550 or connect them via a devicom™ PC PRO.

Make the most of your thermostat

devireg™ 550 has a long list of features, designed to improve and optimize you heating system.
For example, the devireg™ 550 has an adjustable maximum temperature that must be used when installing heating underneath or within wooden floors: the devireg™ 550 will not react to a sudden fall in temperature, because it "understands" that it is most likely just a temporarily occurrance: and the list goes on and on ...
