CONTROL OPERATION
Complete C Control Indicators -- The status
LED
on the Complete C control displays file current status of the
Complete C control. If in Test mode, the LED will flash the
code of the last fault and the almm relay will cycle the stone
number as the fault code. See Table 4.
There are 2 categories of fault types: primary and second-
ary. Primaly fault types include High Pressure (HI)), Low
Pressure (LP), Water Coil Freeze Protection (FPI), Air Coil
Freeze Protection (FP2), and Condensate Overflow (CO). If
fault type is primary, it is always stored in memory. Primary
faults override secondary faults. Secondary fimlt types are:
Over/Under Voltage Shutdown and Performance Monitor
(PM). Secondary faults are retained in memory only if there
are not any primary faults. Secondary faults will not over-
write primary fimlts. See Table 5.

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 fol-
lowed by a 10-second pause. This sequence will repeat continually
until the fault is cleared.

Complete C and Deluxe D Controls -- The follow-
ing operations are common to both Complete C and Deluxe D
coutrol S.
TEST MODE -- Test mode provides the ability to check the
control operation in a timely mmmel: The control enters a
20-minute Test mode by momentarily shorting the test termi-
nals. All time delays are sped up 15 times.
To enter Test mode, cycle the power 3 times within 60 sec-
onds or monentarily sholt the test terminals. The LED will
flash a code representing the last fault when entering the Test
mode. Tile alarm relay will also power on and off during Test
mode. See Table 3. To exit Test mode, sholl the terminals for 3
seconds or cycle file power 3 times within 60 seconds.
NOTE: The flashing code and _darm relay cycling code will
both have the same numerical label. For example, flashing
code 1 will have an alarm relay cycling code 1. Code 1 indi-
cates the control has not faulted since the last power off to
power on sequence.
RETRY MODE --In retry mode, the status LED will start to
flash slowly (one flash every two seconds) to signal that the
control is trying to recover from ml input fault. The control will
stage off file outputs mad try to again satisl_ the thermostat
used to terminal Y. Once the thermostat input calls are satis-
fied, the control will continue normal operation.
NOTE: If 3 consecutive faults occur without satisfying the
thermostat input c_dl to terminal _ the control will go into
lockout mode. Tile last fault causing the lockout is stored in
memory and can be viewed by entering Test mode.
If one try is selected for FPI and FP2 then there will be no
letries for FPI and FP2 faults.
POWER UP MODE -- The unit will not operate until all the
inputs, terminals and safety controls me checked for normal
operation.
NOTE: The compressor will have a 5 minute anti-sholt cycle
upon power up.
