19. ALARM 2 LOW SETTING
Write Command: 28
Read Command: 5c
Interpret:
Temperature reference to compare against secondary sensor for high
alarm output. Temperatures are in whole degree increments. To turn
the low alarm OFF set the alarm temperature to ‐21 (ffeb
16
).
20. ALARM 2 HIGH SETTING
Write Command: 29
Read Command: 5d
Interpret:
Temperature reference to compare against secondary sensor for high
alarm output. Temperatures are in whole degree increments. To turn
the high alarm OFF set the alarm temperature to 200 (00c8
16
).
21. ALARM LATCH FUNCTION
Write Command: 2b
Read Command: 5f
Interpret: 0 = NO LATCHES
1 = ALARM 1 LATCH
2 = ALARM 2 LATCH
3 = ALARM 1&2 LATCH
22. TEMPERATURE 2 DISPLAY
Write Command: 2c
Read Command: 60
Interpret: 0 = OFF
1 = AUTOMATIC
2 = ON
23. ALARM 1 DEADBAND
Write Command: 2d
Read Command: 61
Interpret:
The span in temperature that the control sensor must move before
the ALARM 1 output is toggled off.
For writing, multiply desired deadband by 10
10
then convert to
hexadecimal. For reading, convert to decimal then divide by 10
10
.
1 degree would be 10
10
20 degrees would be 200
10
24. ALARM 2 DEADBAND
Write Command: 2e
Read Command: 62
Interpret:
The span in temperature that the secondary sensor must move before
the ALARM 2 output is toggled off.
For writing, multiply desired deadband by 10
10
then convert to
hexadecimal. For reading, convert to decimal then divide by 10
10
.
1 degree would be 10 decimal
20 degrees would be 200 decimal
