Type Description
PMxTYP Bit 13
Enable Air Quality / Override
for this module:
0 = Not enabled.
1 = When the Air Quality/Override Mode (AIRQ) is
active (Item Address 20 hex, Bit 8), the output is
set to the level specified by the Air
Quality/Override Output Level (Bit 14).
Bit 14
Air Quality/Override Output Level
for this module:
0 = Air Quality/Override output level is 0% or Low
Limit value (whichever is lower).
1 = Air Quality/Override output level is 100%.
Bit 15
Enable Reverse Action
for this module:
0 = Action is set by Item PB (PI controller) or Item
ACT (on/off controller).
1 = When Reverse Action (REVL) is active (Item
Address 26 hex, Bit 3), either by a digital input
or by a reverse action command (REVC, Item
Address 87 hex, Bit 8) from a supervisory
system, the action of the PI or on/off controller is
reversed.
Bit 16
Error Dead Band
(for PI controller only):
0 = Error Dead Band is 0.1%.
1 = Error Dead Band is 1%.
PMxK2 PB/
ACT
Number
Proportional Band
for a PI controller.
Positive number = Direct-acting (cooling).
Negative number = Reverse-acting (heating).
Enter value in % of PV range. See
Proportional/Integral (PI) Controller
above for further
details.
Action
for an on/off controller.
+1 = Direct-acting (cooling).
-1 = Reverse-acting (heating).
PMxK3 TI/DIF Number
Integral Timing
for a PI controller.
Enter value in repeats per minute. See
Proportional/Integral (PI) Controller
above for further
details.
Differential
for an on/off controller.
Enter value in units of the Process Variable.
PMxK4 HIL Number
High Limit
value for the module output (OCM) in %
(PI controller only).
PMxK5 LOL Number
Low Limit
value for the module output (OCM) in %
(PI controller only).
When the controller is in OFF mode and the module
is enabled for OFF mode, the output is set to 0% if
the low limit is greater than 0%, or set to the low limit
value if it is less than 0%.
PMxK6 BSB Number
Set Point Bias during STANDBY Mode
. Value is
normally positive for a cooling controller and
negative for a heating controller.
PMxK7 BNT Number
Set Point Bias during NIGHT Mode
. Value is
normally positive for a cooling controller and
negative for a heating controller.
