energize the mode for at least 2 seconds, then placing
the jumper again, the unit can be scrolled through
modes as in method 1 but more quickly. Unused states,
such as Heat 2 when no Heat 2 is present, shall be
skipped.

Service Tips
• To ensure appropriate unit restart after operating in
Service “
“T TE ES ST T” ” mode, Service “ “T TE ES ST T” ” mode
termination causes a system reset resulting in
execution of the startup sequence identical to initial
power-on startup.
• To prevent undesired activation of Service “ “T TE ES ST T” ”
mode at startup, Service “ “T TE ES ST T” ” mode can only be
activated after an open condition has been detected
on the Service Test terminals.
• When initiating the test mode immediately after
power-up, the RTRM 20 seconds self-test must be
completed before the test mode will work.
• The “ “T TE ES ST T” ” mode bypasses timing functions
including minimum run times.
• “ “T TE ES ST T” ” mode does not bypass safety controls such
as the high temperature limit switch, high pressure
control or smoke detector circuits.
• To help with troubleshooting, unplug J4 from the
RTRM. This removes all optional components such
as the COMM3/4, ECA and RTOM. This may prevent
key features from functioning. Avoid this procedure
on 27.5 to 50 tons units as the Voyager
™
Commercial configuration will be lost.
• Some test functions do not work with LCI installed.
Remove LCI from the circuit before entering the
“
“T TE ES ST T” ” mode.
Emergency Stop Input, LTB 5&6 (3J1-12
on RTRM)
If this input is open, the indoor fan, heat & cooling will
not run in the “
“T TE ES ST T M MO OD DE E” ”. The diagnostic for this
condition is HEAT FAIL + COOL FAIL. When this input is
closed, the unit will restart.
When initiating the “ “T TE ES ST T” ” mode, if emergency stop is
open, the LED on the RTRM will flash one time.
Fan Proving input, 5J7-6 on RTOM
The indoor fan will run in the “ “T TE ES ST T” ” mode for 40
seconds and then stop if this input fails to open (3-
through 25-ton) or close (27.5 to 50 tons) within 40
seconds. The diagnostic for this failure is SERVICE
(pulsing 1.5 – 2.5VDC from RTRM J6-6 to J6-10).
Compressor Disable Inputs, 3J1-8, 3J3-2
(2 Compressor units) on RTRM
If this input is open, ie. 24VAC not present, that
compressor circuit will not run during “
“T TE ES ST T” ” mode.
No diagnostic will be seen.
Compressor Proving Circuits, 3J1-9, 3J3-
3 (2 Compressor Units) on RTRM
If this input is open when the contactor is energized by
the RTRM, that circuit will not run during “
“T TE ES ST T” ”
mode. The diagnostic for this failure is COOL FAIL
(pulsing 1.5 – 2.5VDC from RTRM J6-6 to J6-8).
Gas heat failures, such as TCO, PS, FR will not be
bypassed during “
“T TE ES ST T” ” mode (see unit wiring
diagram). Diagnostics can be picked up at the Ignition
Control Module. Also, an additional diagnostic for this
failure is HEAT FAIL (pulsing 1.5 – 2.5VDC from RTRM
J6-6 to J6-7).
Ventilation Override Mode (VOM), J6 on
the RTOM
While in the “ “T TE ES ST T” ” mode, if a VOM is activated, test
mode will temporarily be halted. When the VOM is
terminated, the “
“T TE ES ST T” ” mode will continue from
where it was halted.
CO
2
Option Through DCV Input on ECA
“ “T TE ES ST T” ” mode will operate normally with a CO
2
signal.
When the economizer step is initiated, the CO
2
signal is
overridden. When the “ “T TE ES ST T” ” mode goes to the next
step, the CO
2
signal is re-established. The economizer
will drive to the closed position and then proceed to
drive open from the CO
2
signal.
ECA Minimum Position Adjustment
During the economizer step (step 2 of test mode), the
"Min pos" on the ECA Module is disabled. It can only be
adjusted during step 1 of the test when the fan is on.
Frostat ™ ™ Input
J7-1, J7-2 on RTOM - if this input closes indicating a
frosted suction line, the compressors will not run
during the “
“T TE ES ST T” ” mode. No diagnostic will be seen.
