Minimum Outdoor Air
Flow Setpoint Failure
Used With: Fresh Air
Measurement (VCM)
option.
Module: VCM
Problem: The GBAS input
assigned to Minimum
Outdoor Air Flow Setpoint
is out of range. (OAFlowStp
is < 0 or OAFlowStp > Max
Unit Airflow
1
Check: Wiring and
external devices on the
associated GBAS input.
1
See Setpoints menu Min
OA Flow Setpoint for max
unit airflows table.
The Active Minimum OA
Flow Setpoint reverts to the
default Minimum OA Flow
Setpoint of the Human
Interface.
(PAR) An automatic reset
occurs after the Minimum
OA Flow Setpoint input
returns to within range for
10 continuous seconds, or
after a different, valid
Active Minimum OA Flow
Setpoint value is specified
(BAS/Network).
Mode Input Failure
Module: RTM
Problem: The RTM Mode
input is out of range. (R <
1k ohm or R > 40k ohm)
Check: Mode input
resistance should be
between 1 Kohm and 40
Kohms. If so, check field/
unit wiring between Sensor
and RTM.
The system mode reverts
to the default (HI set)
System Mode.
(INFO) An automatic reset
occurs after the Mode input
returns to its allowable
range for 10 seconds.
Morning Warmup
Setpoint Failure
Module: RTM
Problem: The GBAS input
assigned to MWU Setpoint
is out of range (Temp < 50
F or Temp > 90 F).
Check: Wiring and
external devices on the
associated GBAS input.
The Active MWU Setpoint
reverts to the default
MWUSetpoint from the
Human Interface.
(PAR) An automatic reset
occurs after the GBAS input
assigned to the MWU
Setpoint input returns to
within range for 10
continuous seconds, or
after a different, valid MWU
Setpoint source is applied
(BAS/Network).
NSB Panel
Communication Failure
Module: NSB Panel
Problem: The RTM has lost
communications with the
NSB Panel (Night SetBack
Panel or programmable
zone sensor).
Check: Check field/unit
wiring between RTM and
NSB Panel.
a. The unit reverts to the
next lower priority mode
switching source (typically
the HI default mode).
b. if the NSB Panel Zone
Sensor is the designated
sensor source for any
functions, those functions
are disabled.
(PAR) An automatic reset
occurs after
communication has been
restored.
