PARAMETER ACCESS AND ADJUSTMENT
The V-TEMP™ Electronic Control has many parameters the user
can adjust to customize the control.
To access the parameters:
a. Press and simultaneously hold the (5) “UP” button and (4)
“DOWN” button for 5 seconds. The first customizable parameter
will appear on the display.
b. To select a parameter to modify use the (5) “UP” button or (4)
“DOWN” button to navigate to the parameter you want to change.
c. Press the (6) “SET” button to go into modify mode.
d. Use the (5) “UP” or (4) “DOWN” button to select the new
parameter value, then press the (6) “SET” button to lock in the
value.
e. You can now navigate to another parameter or you can exit
this procedure by pressing the (1) “ON” button for 1 second.
This will bring back the normal display.

ALARM CODES, DESCRIPTIONS & RESOLUTION(S)
Code Type of Alarm
AL Minimum Temperature Alarm
RESOLUTION:
(a) Verify cabinet temperature
(b) Verify temperature associated with the alarm; see "A1" parameter
AH Maximum Temperature Alarm
RESOLUTION:
(a) Verify cabinet temperature
(b) Verify temperature associated with the alarm; see "A4" parameter
id Door Ajar Alarm
RESOLUTION:
(a) Make sure door is closed
(b) Verify operation of magnetic door switch
PF Power Failure Alarm
RESOLUTION:
(a) Verify what caused the power failure. Press any button to stop alarm.
(b) Verify operation of magnetic door switch
COH Condenser Overheat Alarm
RESOLUTION:
(a) Verify the condenser temperature. See "C6" parameter.
(b) Disconnect power and clean the condenser coil. Check for
obstructed air flow over condenser coil.
dFd Compressor Overheat Safety Alarm
RESOLUTION:
This alarm activates when the defrost terminates on time rather than
temperature.
(a) Verify that the evaporator probe is intact and in the evaporator
coil.
(b) Press any button to restore normal display. The unit will continue
to function normally.
Once the cause that activated the alarm is resolved, the control
restores normal operation except for the following alarms that
require additional intervention:
1. "PF" (Power Failure Alarm): press any button to silence alarm
2. "CSd" (Compressor Overheat Safety Alarm): the cabinet
must be switched "OFF", or disconnect the main power supply
ERROR CODES
Code Type of Alarm
Pr1 Cabinet Sensor Error
RESOLUTION:
The cabinet sensor is located in the return air stream in the evaporator
coil housing.
(a) Verify the integrity of the sensor.
(b) Verify the control sensor connection.
*Note: When this error occurs, the control will go into a safe mode.
The unit will operate in a pre-programmed ON/OFF cycle.
Pr2 Evaporator Sensor Error
RESOLUTION:
The evaporator sensor is located in the evaporator coil within the
evaporator coil housing.
(a) Verify the integrity of the sensor.
(b) Verify the control-sensor connection.
*Note: When this error occurs, the control will go into a safe mode.
The defrost will still activate, but operate on a 30 minute timer.
Pr3 Condenser Sensor Error
RESOLUTION:
The condenser sensor is located on the outlet tube of the condenser.
(a) Verify the integrity of the sensor.
(b) Verify the control-sensor connection.
*Note: When this error occurs, there will not be any "COH" or "Csd"
alarms.
rtc Clock Error
RESOLUTION:
(a) The user must reset the date and time. See the section "SETTING
DATE AND TIME".
*Note: When this error occurs, the control has been without power
for over 48 hours.
Once the cause that activated the error is resolved, the control
restores normal operation except for the "rtc" error. This requires
the date and time to be set.
