CA is the external alarm. When the controller's input is set up as an alarm and that input trips, all outputs go off, so the unit stops cooling. With the input configured as i1F=PAL, the alarm does not clear by itself, and the controller has to be switched off and on again. Wine-Mate wine cellar cooling unit display What to do when CA shows on the wine cellar cooling unit ### Kind of code Power and controller The unit saw its supply dip, surge or drop out, or the controller has lost contact with the board it drives. The cause is as often a shared circuit, a tripped GFCI outlet, a loose connection or a storm outage as the unit itself. A breaker that will not stay on or a scorched smell means switching the circuit off at the panel, standing dry and away from the unit, and keeping the cellar door closed until the technician arrives. ### Usually leads to Wine cellar cooling diagnostic visit A visit that reads the cellar, the room the heat goes to and the cooling unit itself, and ends with one named cause, whether it is a part or the room. ### Shows up as Cellar Cooling Unit Error Code A cellar cooling unit error code appears as letters or digits on the controller, a flashing reading, a blinking light on the unit, or an alarm tone, sometimes while the cellar still holds its temperature. ### Make Wine-Mate Wine-Mate cooling units repaired on site when they will not start, ice over, trip a breaker or leave the walls wet. ### Source Wine-Mate HZD self-contained cooling system manual Current Wine-Mate five-button controller, as printed in the HZD, HZD-DE, 4510-series HZD, HTD, low-profile and SSH, SSD and SSO split-system manuals.

Follow it to the end: the last card says whether this is a visit. 01 Find out what, if anything, your installer wired to the controller's alarm input; if you know of nothing there, the wiring or the input setting is what needs checking. 02 Clear the cause if it is obvious and safe, then switch the controller off and on with its power key. 03 Keep the cellar door shut while the unit is off. 04 If CA comes back, book a visit to check the controller wiring and settings. ### Still there? It usually turns into [wine cellar cooling diagnostic visit](https://winecellarrepair.center/services/diagnostic-visit/). Book with the code and the model number. ### What not to do CA is not a temperature alarm, and the room may be sitting at a perfect 55°F when it appears. It is also different from a dark display, which points to power or the controller itself. ## What you may notice with it. The wine cellar cooling unit problems CA tends to arrive with.

Find out what, if anything, your installer wired to the controller's alarm input; if you know of nothing there, the wiring or the input setting is what needs checking. If it comes back, it needs a visit. ### What can trigger CA on a Wine-Mate? Whatever is connected to the controller's alarm input. Wine-Mate's manual defines only the result, all outputs off, so the device or wiring on that input has to be traced at the unit. ### Will CA clear on its own? Not when the input is set as i1F=PAL; Wine-Mate says it recovers only when the controller is switched off and on. The manual does not describe the other input settings. ### Is it safe to keep resetting CA? Once, after checking what is connected to the input, is reasonable. If it trips again, the cellar goes without cooling each time, so book a visit rather than cycling the power repeatedly. --- **[Read on the site: Wine-Mate CA: the external alarm input has switched everything off](https://winecellarrepair.center/error-codes/wine-mate-ca/)** **[Book a visit with WineCellarRepair.center](https://winecellarrepair.center/schedule/)**
