Zoning ZOE thermostat stuck on “tESt”: we repair it
The Zoning / Madel ZOE radio thermostat of your heating / air conditioning shows “tESt” and its buttons no longer respond?
Has your installer told you that these thermostats are no longer sold, that the new ones are not compatible with your current installation and that everything will have to be replaced?
In most cases, we can repair your thermostat and unlock it. There is no need to buy a new one, let alone replace your whole installation.

Why the thermostat stays on “tESt”
Every time it starts, the thermostat checks its settings: which room it belongs to, which control unit it talks to, its temperature limits and the weekly schedule. If any of these settings is damaged or incomplete, it stops on “tESt” and no button works.
This mostly happens when the batteries are weak or were removed at the wrong moment, while the thermostat was saving something. New batteries are not enough: the damaged setting stays saved and has to be redone.
Affected thermostats
Zoning ZOE radio thermostats (formerly “Madel ZOE”): the small white wall unit that controls a room's temperature, used in a zoned heating / air-conditioning installation. Both the main (“master”) thermostat and those of the other rooms (zone 2, 3, 4…) can be repaired. Unsure about your model? Send us a photo.

Frequently asked questions
What does “tESt” mean on a Zoning ZOE (formerly Madel) thermostat?
“tESt” (for “test”) is an error message: at startup the thermostat found its settings damaged or incomplete. It stays locked and ignores the buttons. It is usually not broken: its settings need to be put back in order.
Will replacing the batteries fix it?
No, not once the settings are already damaged. New batteries help prevent a repeat, but the settings must be repaired.
Can my Zoning ZOE thermostat be repaired?
In most cases yes, as long as the circuit board is not physically damaged (impact, water, corrosion). We check this when it arrives, and if it cannot be repaired, nothing is billed.
Which thermostats can be repaired?
Zoning ZOE (formerly Madel) radio thermostats, whatever your heating or air-conditioning installation, both the main one and the zone ones. If in doubt, send us a photo.
How long does it take?
Your thermostat is repaired within 72 hours at most after we receive it. The total time also depends on postal shipping, usually a few days each way.
Why not contact the manufacturer?
Zoning no longer manufactures these thermostats. The newer models are generally not compatible with your installation. This service is independent: we are affiliated with neither Zoning nor Madel.
