S, S) 1 = 3 days (M-F, S,
S) 2 = 2 days (M-F, S-S)
3 = 1 day (Sun-Sat)
0 0 allows all 7 days to be individually programmed. 1 allows Mon - Fri, Sat &
Sun to be programmed separately. 2 allows Mon - Fri and Sat - Sun to be
programmed the same. 3 uses the same program for each day of the week.

0 = Disallowed
1 = Allowed
0 If allowed, Supply Fan operation can be programmed for On or Auto

display.
12 Check Filter
Interval
0 = Disabled 3000 to 50
in 50 hour increments
350 Adjustable in 50 hour increments. The CHECK FILTER icon will flash when
the accumulated run time is greater than the interval setting. Pressing the
erase button will reset the counter.
13 Display Zone

16 Buzzer Options 0 = Key Press Only
1 = Key Press and Check
Filter
2 = Key Press, Check
Filter, and System Failure
1 Buzzer will sound for a 1/2 sec for every minute if option is set for 1 or 2.
17 Zone Temperature
Calibration
Zone Temperature
Displayed
0 offset This allows for field calibration in 1.0 degree increments of either the
internal sensor on the ZSM or the remote sensor if used.
18 Baud Rate 0 = 1024 baud
1 = 1200 baud
1 Set to Zero for 3 - 25 Ton Voyager Units built before Jan. 1, 1996 that have
the original UCP.
19 CV or HP
