Outside RH Not
Configured
Enthalpy economizer
is configured on the
RTULink but an
outside air relative
humidity sensor is not
configured.
Verify that an outside air relative humidity sensor is connected to one of
the RTULink inputs. Install and connect one if one has not already
been connected. Once the sensor is connected, configure the sensor
via the onboard HMI. For details on how to configure an RTULink
input, view the FUNCTIONALITY portion of this manual
Return RH Not
Configured
Differential enthalpy
economizer is
configured on the
RTULink but a return
air relative humidity
sensor is not
configured/connected.
Verify that a return air relative humidity sensor is connected to one of
the RTULink inputs. Install and connect one if one has not already
been connected. Once the sensor is connected, configure the sensor
via the onboard HMI. For details on how to configure an RTULink
input, view the FUNCTIONALITY portion of this manual
Invalid Schedule
RTULink has received
a schedule from
CASLink that is
invalid for its current
control mode (i.e. a
set point schedule
has been passed and
the board
doesn’t
support set points).
Login to CASLink and ensure that all RTULink board data has
timestamps that are current. If the board is currently reporting all data,
overwrite the current schedule with an “OFF” control mode and pass a
new one.
Gap In Schedule
The RTULink has
been disconnected
from CASLink and
there is a gap in
scheduling.
Check all RTULink communication network wiring. If the wiring is
accurate, ensure the communication module is connected to CASLink
by viewing the latest heartbeat in CASLink.
Stat Missing
(Return, Outside,
Intake, Discharge,
Space)
If the temperature
sensor signal being
sensed is too low, a
missing fault will be
active.
Install and wire sensor.
Check for faulty wiring to the sensor.
Stat Broken
(Return, Outside,
Intake, Discharge,
Space)
If the temperature
sensor signal being
sensed is too high, a
broken fault will be
active.
Install and wire sensor.
Check for faulty wiring to the sensor.
Space HMI Missing
One of the HMIs in
the system is not
connected properly,
or one of the settings
is not properly set.
Verify that the “# of HMIs” is set correctly.
Verify there is no damage to the HMI(s).
Check for loose or damaged wiring to the HMI(s).
If space temperature is being utilized, make sure “HMI Averaging” is set
to ‘On’ for all space HMIs.
HMI Config Error
HMI is not connected,
or HMI is assigned
incorrectly.
Install HMI or change HMI address using bottom 2 buttons on HMI.
