During the trial run, set the slide switch SWS2 on the board within the control box to the lower position.
It is set to the upper side by default to force the pump and compressor to stop to protect the pump from
being harmed by the anti-freezing process if there is no water flowing or the valve is closed before the
test run. Upper side: A (under preparation)
Lower side: B (auto)
Always set to the lower side.
* Setting to the upper side forcefully stops the pump and compressor thus the unit does not operate.
* When SWS2 is set to the upper side, the display shows “P.OFF” and the setting cannot be
made. When “P.OFF” appears, set SWS2 to the lower side.

4. Table of settings items
Set the dip switches SW2 and SW3 as shown in the table below to set the value for the items in the "Setting item" column.

*1 Set to “1” when individual system and connected to AE-200.
*2 Set to "3" when using all modes (Mode 1,2, and 3).
Set to "2" when using mode 1 and mode 2.
Set to "1" when using mode 1.
*3 Only Six-sensor method
*4 Required only when AE-200 is connected.
*5 It can also be set with the PAR-W31MAA or AE-200.
*6 When secondary control is enabled.

If water shutoff error 2601 occurs during the air bleeding operation, resolve the issue, then change the
setting of PCB slide SWS1 from LOCAL to OFF, and back to LOCAL again. The air bleeding operation starts
again.
(You can clear water shutoff error by turning the power OFF and ON again. The equipment enters standby
mode in this case.)
(You can also clear water shutoff errors by changing the setting of PCB DIP SW1-8 or 1-9 from ON to OFF.
Turning DIP SW1-8 OFF starts circulation heating circuit air bleeding (manual). Turning DIP SW1-9 OFF
starts water supply circuit air bleeding (manual).)

If the start-up operation has not
finished,
SW2-9 and SW2-3 need to be set as a

When the power is switched on, the following codes will appear on the LED:
• [EEEE] will appear on LED1 in the circuit board
[--ng] is displayed before the water flow rate adjustment operation is
performed. Cancel the [--ng] display by using one of the following
methods.
•Press SWP3.
•Press SWP1 or SWP2.

Performing a soft reset
(1) Set the rotary switch SWU3 to "F." [FFFF] will appear in the LED1.
(2) Press and hold the push switch SWP3 for one second or longer.
• While the system is starting up [9999] will appear on LED1.
• When start-up is complete, a control property [0001] will appear.
• Then, five seconds later, [FFFF] will appear.
(3) Set the rotary switch SWU3 back to "0."
• If the start-up process has already been completed, [FFFF] (instead of [EEEE]) will appear when
the rotary switch SWU3 is set to "F."
• [--ng] is displayed before the water flow rate adjustment operation is performed.
