|MaintenanceInfo=It is suggested the air filter be changed once or twice a year. The filter is 10" x 20" x 1".



After programming (the compressor), this command need to be run to setup switch mode stuff, which cannot be put in the eeprom.

Either in the web ui, go to configuration -> module, set gpio3 to DS18x20, or 

<code>
mosquitto_pub -t "cmnd/i3/inside/commons/snapple-vending-compress/GPIO3" -m "4"
</code>

== Replacement Controller ==
Since the machine's controller is braindead, {{Pretty Link|Amelia Meyer}} has started work on a replacement, DIY, open-source, organic, chemical-free, holistic controller.

=== Pinouts ===

==== Rows ====
There are six rows, with nine columns each. All rows use the same pinout, on a 10-position Molex 2695KK connector.

==== Display ====
Display is run by an OKI (MS)C1937-01 14/16-segment 16-digit LED driver, driving (8) 14-segment digits with decimal points. This unit uses a 3M C-GRID 2x13 connector.

==== Vend-Confirm Sensor ====
This appears to be an off-the-shelf industrial-style retroreflective beam-break sensor. It uses a 12-position Molex 2695KK connector. Pins 2-4, 6-8, and 10-12 are unpopulated.

==== Old Temperature Sensor ====
Labeled <code>CR0023212-0.2-163400024</code>, this is supposedly a SPI-connected temperature probe. However, no response could be elicited from it, and it will be replaced with an AM2302. It uses a 6-position Molex 2695KK connector, with pin 6 unpopulated.

==== New Temperature Sensor ====
New temperature/humidity sensor is a AM2302, serial number <code>15120F902</code>. It uses a 3-position JST-XHP connector.

==== Door-Open Sensor ====
This is a simple plunger-style switch, on a 3-position Molex 2695KK connector. Pin 1 is unpopulated. The switch is open when the door is.
