Description
The Johnson Controls C-2220-14 is a High/Low Selector Slave Unit that is used in pneumatic HVAC systems which is an abbreviation for Heating, Ventilation, and Air Conditioning. Using data that is readily accessible to the public, I can tell you the following: Function: It regulates the pressure of the system in cooperation with a master module (possibly C-2220-13). It transmits a high- or low-pressure signal to the particular zones once it receives it from the master module. Slave Unit: This classification implies that for the C-2220-14 to work, it requires instructions from a master module.
