ALL MODES


Turn ON/OFF ARP

This set of instructions applies to the following controls: v2.0, v2.1, v3.0, v3.1, v4.0 & 4.1

Why power off the ARP?

When the ARP is turned off, it is no longer controlling your fridge. This can be handy if one feels the need to take the ARP out of the loop for testing. When the ARP is off your fridge will run full time without temperature monitoring. In addition, the ARP needs to be turned off to change the control modes.


ARP Control Modes

PLEASE NOTE THAT ALL OF THE CONTROL MODES (ARP, SP0, SetUp, or Auto Tune) MUST BE ENTERED BY TURNING OFF THE CONTROL AND THEN STARTING THE CONTROL IN THE DESIRED MODE.

This set of instructions applies to the following controls: v2.0, v2.1, v3.0, v3.1, v4.0 & 4.1

What are control modes?

The ARP Control comes ready to use on 90% of Dometic and Norcold refrigerators. Thus, one should not have to change the control mode unless the ARP needs tuning or the fridge needs troubleshooting.

The ARP has 3 modes of operation as follows: The ARP Control mode, the No Set-Point mode, and the Auto Tune mode. Please read about the respective modes before attempting to use them.


Display Temperatures

This set of instructions applies to the following controls: v2.0, v2.1, v3.0, v3.1, v4.0 & 4.1

Here is the power of the ARP, operators and technicians are no longer in the dark guessing about their fridge cooling unit. By reading the temperatures the ARP displays, one knows the state of the fridge cooling unit.

NOTE: The v4.0 & v4.1 will display an additional setting, the voltage going to the fridge. This is a supper handy diagnostics tool!


TEST ARP CONTROL

This set of instructions applies to the following controls: v1.0, v1.1, v2.0, v2.1, v3.0, v3.1, v4.0 & 4.1

Upon initial installation it takes about 3 minutes to check the wiring of the control. This test shall be preformed upon initial installation and at regular intervals thereafter to insure the proper wiring and on/off control function of the ARP.


Fan Temperature Adjustment

This set of instructions applies to the following controls: v2.1, v3.1, v4.0 & 4.1

Want to control when your fan turns on and off? The fan setting can be changed either by moving the sensor to a higher absorber coil or by using this software setting to fine tune the set-point temperature.


Diagnostics Variables

These steps must be followed in order to put the control into the SetUp mode:
1) Click here to learn how to turn off the Fridge Defender.
2) Click here to change to the SetUp mode.
3) Please note that the following variables shall be recorded if contacting us for your fridge or the Fridge Defend/ARP Control troubleshooting. The version of controller is identified at the top of each column, the subsequent rows are the required variable values that we need to help you (N/A= Not Applicable for a version of controller):

The values that would be sent to us via email for the video example would be: AtO= C-H; AtS= 217; Abs= 217; tr= 0; Opn= 0; Sht= 0; E7= 0; E9= 0. These are the values that the Fridge Defend would have if the control is set to the default C-H control function, the control has not tripped, nor has there been any other recorded events.  See troubleshooting guide for definitions of variables.

v1.0/v1.1 v2.0/v2.1 v3.01/V3.1/v3.11 v4.0/v4.1
AtO AtO AtO AtO
AbS AbS AtS AtS

N/A FAn tr tr
N/A N/A OPn OPn
N/A N/A SHt SHt
N/A N/A N/A E7 & E9*

* Use SetUp button to toggle between E7 & E9


Set-Point Functions

This set of instructions applies to the following controls: v3.0, v3.1, v4.0 & 4.1

v2.0 and v2.1 set-point functions are similar to what is shown with the exception that there is no 'PId' set-point mode in these earlier controls.

Read and understand the ARP Manuals before changing the set-point functions. Most fridges operate with the default C-H set-point setting. The exception would be some older Dometic fridges and Norcold 1200/1210 series 2013 year on and Norcold model 2118 require the 'PId' setting.


Store New Settings

This set of instructions applies to the following controls: v2.0, v2.1, v3.0, v3.1, v4.0, v4.1

All changes made while in the SetUp mode need to be stored before exiting the SetUp mode.
