Remote Controller Check; Test Run [For Wireless Remote Controller]; Before Test Run; Self-Check - Mitsubishi Electric PEH-P400 Manuel D'installation

11.4. Remote controller check

If operation cannot be carried out from the remote controller, use this function to diagnose the remote controller.
1 First check the power mark.
When normal voltage (DC12V) is not applied to the remote controller, the power
mark goes off.
When the power mark is off, check the remote controller wiring and the indoor
unit.
2 Switch to the remote controller check mode.
When the H [CHECK] button is held down for five seconds or longer, the dis-
play shown below appears.
3 Remote controller check result
When remote controller is normal
Since there is no problem at the remote controller, check for other causes.
When the problem is other than the checked remote controller
(Error code 2) "E3" "6833" "6832" flash → Cannot send
There is noise on the transmission line, or the indoor unit or another remote con-
troller is faulty. Check the transmission line and the other remote controllers.
4 Remote controller check reset
When the H [CHECK] button is held down for five seconds or longer, remote controller check resets and the "PLEASE WAIT" and RUN lamp flash. Approximately 30
seconds later, the remote controller returns to the state before remote controller check.

12. Test run [for wireless remote controller]

12.1. Before test run

s s s s s After completing installation and the wiring and piping of the indoor and
outdoor units, check for refrigerant leakage, looseness in the power sup-
ply or control wiring, and wrong polarity.
s s s s s Use a 500-volt megohmmeter to check that the resistance between the
power supply terminals and ground is at least 1.0 M
s s s s s Do not carry out this test on the control wiring (low voltage circuit) termi-
nals.
Warning:
Do not use the air conditioner if the insulation resistance is less than
Ω
1.0 M .
Caution:
The compressor will not operate unless the power supply phase connection
is correct.
When the A [FILTER] button is pressed, remote controller check begins.
When remote controller is faulty
(Error display 1) "NG" flashes → Remote controller send/receive circuit abnormal
Remote controller switching is necessary.
(Error display 3) "ERC" and data error count are displayed → Data error generation
ERROR CODE
"Data error count" is the difference between the number of bits of remote controller
send data and the number of bits actually sent to the transmission line. In this case,
the send data was disturbed by the noise, etc. Check the transmission line.
When data error count is 02
