CIRCUITS & ZONES (CONTINUED)

For options A and C in Fig 9.1.3, configure circuit Alarm Text as "manual" and voltage band B1 as "Instant Alarm" (refer to table below).

Voltage	Default	Program	Fan
Band	State	State	Control
B5	Fault		Switch wiring open circuit
B4	Normal		"Auto"
B3		Normal	"Auto"
B2	Alarm		"Off"
B1		Inst Alarm	"On"

Configure the zone as non-latch, Status, non Anc1/Anc2/Bells.

In output logic, "off" is ZnD, "On" is ZnM, (for AZC number n).

For Option B in Fig 9.1.3, configuration is similar but in the output logic, "off" is ZnF and "on" is ZnA.

For two AZC inputs:

FIG 9.1.4

FAN CONTROL WITH TWO AZCs & ROTARY (OR CENTRE-OFF) SWITCH

Program B1 for both AZCs as "Instant Alarm", Alarm Text as "Manual".

Zone 1	Alarm	"Fan Control Off"
Zone 2	Alarm	"Fan Control On"
Both	Normal	"Fan Control Auto"

Configure both zones as non-latch, Status, non Anc1/Anc2/Bells.

Fan Inputs

The exact requirement depends on the particular fan motor controller, and the contacts available (e.g. "Run", "Fault"). Commonly "Run" is provided by an air flow switch (AFS), and is required to connect to an AZC so that it can become part of a logic equation (as per circuits 3 & 4 of standard module 1945-1-1/4 following).
