P-Bipolar Ionizer
designed for LG/LC/LH/LD/KG/KC/KH 024-300 units. The
ionizer is equipped with dry contacts which allow a Build-
ing Automation System (BAS) to interface and indicate
ionizer functionality.
Note - The BAS will be able to monitor units equipped with
M4 Unit Controllers only. Units with an M3 Unit Controller
or no controller need to be connected to a separate mon-
itoring system.
The Ionizers are also equipped with a green LED which
power is delivered to the Ionizers and ions are generated.
See table 10 for unit application.
