Carrier VAV

[leegally1983]

Hi
ive been asked to quote a service visit on a large number of VAVs in a office , i am not familiar with them as such i was wondering if anyone would know what is to be done during a service on these units. I have also been told by the client that we will need a trend engineer along so any info from you would be appreciated.

Start by getting the model numbers and then download the manuals from Carrier.

From memory you'll need to check/calibrate the AHU and then check the boxes.

Depending on the age of the kit then the controllers can go sticky.
