Dilution Air Connection
The dilution air connector provides field connection points for an auxiliary dilution air system
and/ or associated external dilution air system sensors. The connections supported include a
MIOX external dilution air enable, MIOX external dilution air system failure input, and two
other failure inputs. The failure inputs can be connected to either external differential
pressure switches or an external flow switch with dry contacts. Pins 19 and 20 (Figure 12)
should be wired to the Dilution Air Panel Relay to turn on the auxiliary panel. Table 5
provides the description for each terminal.
