3.12 E8 Error
It would be rare if ever that E8 would appear.
If E8 does appear the first step is to turn off
the control and turn back on to see if the
error clears? If the error does not clear after
this procedure please contact ARP Control
by using our Contact Us form at
www.ARPrv.com.
3.13 E10 Flashing when Test ARP with
SetUp Button
If one is testing the ARP internal relay with
the SetUp button while in ARP control mode,
and E10 flashes, there is an internal relay
failure or the control has been installed
parallel with a recall device, see solution
below in the

F2 at ARP Startup

3.14 E11 Trigger Event
The ARP Control detected an overheat
situation and the power was not turned off to
the fridge. See solution in
section, if solution cannot be found, contact
ARP and remove the ARP Control from
service.
3.15 F1 MCU ADC Error Checker
This error can occur due to electrical noise
on the RV wiring. This error will not affect the
ability for the control to measure boiler
temperature. Thus, it is not a critical error.
The best way to test if there is an issue, go to
the User Guide section 1.4, or below section
10.1 to read the fridge voltage with the ARP,
then check this voltage reading with an
accurate DMM. The readings should be
within +/-0.2 volts.
3.16 F2 at ARP Startup
F2 is tested at startup, and if the periodic
testes are enabled, this test checks that the
ARP internal relay can turn power off to the
yellow wire controlling the fridge.
If this error is seen after installation of the
ARP, the control has been wired incorrectly.
Solution: The control needs to be turned off
by disconnecting the ARP red wire. Next,
disconnect ARP yellow wire; be sure not to
ground this wire during testing. Reconnect

section.
F2 at ARP Startup
the ARP red wire so that control turns back
on. Check to see if F2 is still displayed? If F2
is not displayed, internal relay is functioning.
Solution, rewire ARP to be in series with
recall. If F2 is still displayed during startup
test while ARP yellow wire is disconnected,
contact ARP and discontinue use of control.
3.17 F3 Boiler Sensor ADC Cal
This error can occur due to electrical noise
on the RV wiring. This error can be checked
by service personnel by putting the control
into SP0 mode and perform a senor check,
section 10.3 below.

3.18 CRC Tests

These tests check the code within the MCU
for integrity.
F6 MCU Set-Point Memory CRC:
This test can fail for a number or reasons,
including but not limited to power supply
brown out (electrical noise on the RV wiring),
user operator error during Auto Tune, or
other events that result in a memory
corruption. This error can generally be fixed
by restoration of the factory default settings,
see section 2.21, Restore ARP Defaults.
F7 MCU Set-Point Tune Memory CRC:
Use the same set of rules stated above for
the F6 error. Also, this error is specific to an
improper Auto Tune session. If this is the
case, run Auto Tune again or see section
2.21, Restore ARP Defaults.
E13 MCU Code Memory CRC:
This error can occur due to electrical noise
on the RV wiring. The first step is to turn off
the control and restart it while viewing the
ARP display for error messages. If the
control passes all of the functional tests, then
this error may have been recorded due to
noise on the system during the automatic
test procedure. If this is the case, this error
will be cleared. Also, perform all of the
manual functional tests, see User Guide
section 1.7.
3.19 E12, E14, E15
These errors can occur due to electrical
noise on the RV wiring. See
Memory CRC above for test procedure.
