Retry Mode; Aquazone Deluxe D Control Led Indicators - Carrier AQUAZONE 50PSW036-360 Installation And Service Instructions Manual

Upon entering Test mode, the status LED (light-emitting di-
ode) will flash a code representing the last fault. For diagnostic
ease at the thermostat, the alarm will also cycle during Test
mode. The alarm relay will cycle on and off similar to the sta-
tus LED to indicate a code representing the last fault, at the
thermostat. Test mode can be exited by shorting the test termi-
nals for 3 seconds. See Tables 10-12.
NOTE: Deluxe D control has a flashing code and alarm relay
cycling code that will both have the same numerical label.
For example, flashing code 1 will have an alarm relay cycling
code 1. Code 1 indicates the control has not faulted since the
last power off to power on sequence.
In Retry mode, the status LED will start to
Retry Mode —
flash slowly to signal that the control is trying to recover from
an input fault. The control will stage off the outputs and try to
again satisfy the thermostat used at terminal Y. Once the ther-
mostat input calls are satisfied, the control will continue normal
operation.
NOTE: If 3 consecutive faults occur without satisfying the
thermostat input call to terminal Y, the control will go into
lockout mode. The last fault causing the lockout is stored in
memory and can be viewed by entering Test mode.

NOTES:
1. Slow flash is 1 flash every 2 seconds.
2. Fast flash is 2 flashes every 1 second.
3. EXAMPLE: "Flashing Code 2" is represented by 2 fast flashes followed
by a 10-second pause. This sequence will repeat continually until the
fault is cleared.
Aquazone™ Deluxe D Control LED Indica-
tors —
STATUS LED — Status LED indicates the current status or
mode of the Deluxe D control. The Status LED light is green.
TEST LED — Test LED will be activated any time the De-
luxe D control is in Test mode. The Test LED light is yellow.
FAULT LED — Fault LED light is red. The fault LED will
always flash a code representing the last fault in memory. If
there is no fault in memory, the fault LED will flash code 1 on
the display and appear as 1 fast flash alternating with a
10-second pause. See Table 12.
