What is the dead zone of a thermostat? Verified
Many modern thermostats have a dead zone. If the temperature deviates less than 4°C from the set temperature, the system will not heat or cool. This so called dead zone of the thermostat prevents the system from turning on and off too often, saving energy.

What is the best place to mount a thermostat? Verified
The best place for a thermostat is approximately 1,5 meter above the ground. Never place the thermostat nead a radiator or other heat emitting equipment or in direct sunlight. Choose a room that is used often. In most cases this is the living room.

Hello, I made all the adjustments following an electrical problem with the thermostat. Just one problem remains and I'm sure it's a detail! When I note 8 o'clock, this is the time at which the boiler starts up instead of getting 20 °, at 8 o'clock. How should I do it? Thank you so much. Annabel

The product may only work every second time it is accessed. At least once a week I have to read the message "Your ATAG One cannot be reached". WiFi and Internet work without complaint at almost 100MBit. All other devices in the house can not be controlled via the Internet, except for this ATAG One.

Hello, I have an ATAG boiler with the ATAG thermostat, in the central heating settings I have the choice between two modes, "thermostat or climate" what does that mean? If I select the climate mode, I then have another parameter that appears "influence atmosphere" I then have 5 choices available to me (stop-minus-medium-plus- room temperature control) What would be the best setting? Thanks in advance

No manual in French, or even in English, except a "quick reference" which does not explain much. In addition, whether one speaks to their customer service in Dutch, French or English, emails go unanswered. As for the thermostat, it disconnects spontaneously about once a week and it is then necessary to carry out a complete factory reset and to re-parameterize everything. And the app is catastrophic. In short, a terrible crap to be avoided as a matter of urgency!

This thermostat is OFTEN disconnected completely unexpectedly (six disconnections in two months of installation). It is then necessary to do a factory reinstallation, but also to uninstall the app and reinstall it. The maneuver is very hazardous, takes one to two hours and does not work every time. As a previous speaker said, the after-sales service is NON-EXISTING !!! It is a real shame. In short, 200 € of throws. I will install another thermostat, probably a NETATMO.

The boiler was turned off for a few days. The atag one thermostat has a blue button that flashes but does not accept any other command. What should I do?
