System Testing & Troubleshooting
Rooftop Module Data
Storage Error
Problem: There was a data
transmission error or an older
version Human Interface
(prior to 32.xx) is connected
to the control system.
(Intellipak II RTM requires
compatible Human Interface
ver 32.xx or higher)
Check: This can be caused by
an intermittent power loss.
Turn the unit off for 1-2
minutes, then back on again.
If diagnostic persists, then the
RTM may need to be replaced.
RTM and Human Interface
software versions.
An error occurred while the
RTM was writing data to its
internal non-volatile memory
(EEPROM). The RTM detects
an Human Interface software
version less than 32.xx
A manuel reset diagnostic will
be displayed at the Human
Interface and unit operation
will be prevented until reset.
(PMR) A manual reset is
required anytime after the
Diagnostic is set. The
Diagnostic can be reset by the
Human Interface or Tracer, or
by cycling power to the RTM.
RTM Auxiliary Temperature
Sensor Failure
Problem: The RTM Auxiliary
Temperature sensor data is
out of range.
Check: Sensor resistance
should be between 830 ohms
(200 F) and 345.7Kohms (-40
F). If so, check field/unit
wiring between Sensor and
RTM.
At least one enabled unit
function has the RTM Auxiliary
Temperature input designated
as its sensor, and the unit is
reading a signal that is out of
range for this input
(Temperature < -55 F or
Temperature > 209 F).
The functions with the RTM
Aux Temperature input
designated as their sensor are
disabled.
(PAR) An automatic reset
occurs after the designated
Zone Temperature input
returns to its allowable range.
In order to prevent rapid
cycling of the Diagnostic, there
is a 10 seconds delay before
the automatic reset.
RTM Space Humidity
Sensor Failure
Problem: Humidity sensor out
of range.
Check wiring from Humidity
Sensor to RTM module. Check
for proper voltage range on
RTM Humidity Sensor input if
wired correctly.
RTM Zone Humidity input out
of range: Humidity <1% or
Humidity >100%.
The Dehumidification and
Humidification functions are
disabled if the RTM Space
Humidity Sensor is selected as
sensor source for these
functions.
(PAR) An automatic reset
occurs after the RTM Zone
Humidity input returns to
within range continuously for
10 seconds.
RTM Zone Temperature
Sensor Failure
Problem: The RTM Zone
Temperature sensor input is
out of range.
Check: Sensor resistance
should be between 830 ohms
(200 F) and 345.7Kohms (-40
F). If so, check field/unit
wiring between Sensor and
RTM.
At least one enabled unit
function has the RTM Zone
Temperature input designated
as its sensor, and the unit is
reading a signal that is out of
range for this input
(Temperature < -55 F or
Temperature > 150 F).
The functions with the RTM
Zone Temperature input
designated as their sensor are
disabled.
(PAR) An automatic reset
occurs after the designated
Zone Temperature signal
returns to its allowable range.
In order to prevent rapid
cycling of the Diagnostic, there
is a 10 second delay before
the automatic reset.
