“Purging” is the process of clearing an air conditioner’s (AC’s) unit’s internal lines and hoses. This is frequently done before recharging freon but. many newer model AC units, such as Honeywell units, purge the system on startup.Click to see full answer. Also to know is, what does purge light mean on Honeywell?PURGE Solid when in purge (lasts 2 minutes at power-up and after a call for heat or cool). Blinking when the DATS sensor has failed, or the wires are shorted or open. Will blink for 3 minutes at power-up if DATS is not present. how do I purge my AC with nitrogen? Break the system vacuum with nitrogen introduced at the side port of the core tool. Break the vacuum with nitrogen to that equivalent to atmospheric pressure (760,000 microns) then purge nitrogen through the system at 1-3 psig. from the high to the low side letting it vent out the open port of the core tool. Secondly, what happens if air gets in AC system? When air enters a refrigeration system, it collects in the top of the condenser and is trapped. Air will cause a reduction in condenser surface area, which will cause a high condensing pressure. Air can enter the refrigeration system through a leak in the low side of the refrigeration system.What is a Zms sensor?The Zoning Mixed Air Sensor, Model S1-ZMS, is a duct mounted sensor used with the S1-MMZ, S1- MMH3 and S1-ZMS4 Zone Control Panels. When the supply air temperature rises above the heating set point or below the cooling set point, the zoning panel will lockout the heating or cooling equipment.
