Codes through HVAC

[Unavita]

When I try and do a search these days I get an "oops" notice. SO- can anyone point me in the right direction to read the codes the HVAC system is putting out?

You need a digital scanner to communicate with the HVAC system in the 140 chassis. Or, it is able to display fault codes directly on the LCD displays.

Click here, see page 21.

There are some fault codes on the screen for things like thermostat, inside and outside temp readings. I read code 14 with the blinky too. I attached the video but can decipher it here in a bit.

14 is Lambda on/off.
