(3) System configuration procedures: Individual system
1. Set the dip switches on the MAIN circuit
board.
Switch settings on the MAIN circuit
Set the dip switches (labeled A in the figure at
right) that correspond to the items below,
according to the local system.
• Water temperature control based on the
external water temperature reading
• Water temperature control based on the inlet
water temperature
Refer to "Dip switch settings table" (page 69) for
further details.
2. Switch on the power to the unit.
Check for loose or incorrect wiring, and then
switch on the power to the unit.
When the power is switched on, the following
codes will appear on the LED:
• [EEEE] will appear on LED1 in the MAIN
circuit board (labeled A in the figure at right).
• [9999] will appear on LED1 in the SUB circuit
board (labeled B in the figure at right).
3. Set the preset values with the switches on the MAIN circuit board.
(1) Press either one of the push switches SWP1, 2, or 3 (labeled A in the
figure at right) on the MAIN circuit board.
* [EEEE] will disappear, and an item code ([101]) will appear on LED1
(labeled B in the figure at right).
(2) Use SWP3 to toggle through the item codes and select an item code to
change its current value. (The item codes will appear in the following
order: [101]→[102]→[104]→[107]→[101] (back to the beginning).)
(3) Use SWP1 to increase the value and SWP2 to decrease the value.
(4) Press SWP3 to save the changed value.
Following the steps above, set the value for the following items as
necessary.
