Introduction You have purchased a devireg™ 540/550 thermostat, which forms an integrated part of a deviheat™ system. DEVI™ has developed the devireg™ 540/550 to make your floor heating an even more environmentally correct way of heating your home. devireg™ 540/550 will work dynamically with both the room and floor temperature in order to give you the highest possible comfort in the most economical way.
Introducing devireg™ 540/550 devireg™ 540 is an advanced temperature controller, with a built-in Timer. devireg™ 550 ONLY: devireg™ 550 is an adaptive temperature controller, specially designed for floor heating systems. The devireg™ 550 will measure the radiant comfort from the floor combined with the comfort from the air temperature in the room to offset the outside weather condition.
All this means that as soon as you have set your devireg™ 550 at your desired comfort temperature, you do not have to do anything else. devireg™ 550 will automatically adjust the heating to meet your requirements for comfort and economy, no matter how the weather is changing outside. This also means that devireg™ 550 is capable of detecting a sudden temperature drop in the room.
