FAILURE RESPONSE
Cannot control at ZSM, unit

No Heating or Cooling ZSM
"Fan" selection switch

This input is for "indication"
only and does not effect the
normal operation of the unit.
Unit will not operate in any
mode.
Fan speed command remains
at 0%.
Closed - Unit will not operate
1. In the event a required Traq
control input is out of range
the Traq Minimum Position
Request will be disabled and a
static value of 10% will be
utilized for minimum position
at all times.
2. If BAS is in "remote control"
and sending a valid OA
Minimum Position Setpoint
that setpoint will be used for
OA Minimum Position,
however a diagnostic
indication will continue to be
set via the BAS and the 2-
blink code will be initiated on
the RTRM to indicate a
problem.
In the event of the loss of a
required control parameter for
DCV when paired with Traq
control the system will revert
to using on the Design
Minimum OA CFM Setpoint
and continue Traq control
functionality without DCV.

DIAGNOSTIC
If a sensor is used at RTRM J6-1 and J6-2,
Cool Failure Output at RTRM J6-8 to J6-6
"COOL" LED Blinks at ZSM. If RTRM senses
a zone temp input and then it is lost,
CV Cool Failure Output at RTRM J6-8 to J6-
6 "COOL" LED Blinks at ZSM
Heat Failure Output at RTRM J6-7 to J6-6
"HEAT" LED Blinks at ZSM.
Possible Cool Failure at RTRM J1-8 to
Ground, 0 VAC. "COOL" LED Blinks at ZSM.
Possible Cool Failure at RTRM J3-2 to
Ground, 0 VAC. "COOL" LED blinks at ZSM.

SERVICE LED ON 2-30 Vdc present at
RTRM J6-6 and J6-10.
Service Failure Output at RTRM J6-6 to J6-
10 "SERVICE" LED blinks at ZSM.
Heat and Cool Failure Output at RTRM J6-7
to J6-6 & RTRM J6-8 to J6-6 "HEAT" and
"COOL" LED's blink at ZSM.
Check to make sure the float position is not
in a tripped condition and verify an "open"
between wires connecting to RTOM J6-1,
J6-2.
A diagnostic will be set via BAS
communication and the 2-blink code will be
initiated on the RTRM to indicate a
problem.
The proper failure code will be set on the
RTEM and an indication of the failure will be
set via the BAS Communication packet.
