4. Perform an initial setup. (MAIN circuit side)
(1) Set the rotary switch SWU3 (labeled A in the figure at right) to "F."
[EEEE] will appear in LED1 (labeled B in the figure at right). *1
(2) Press and hold the push switch (SWP3) (labeled C in the figure at right)
for one second or longer.
• While the system is starting up [9999] will appear on LED1 (labeled B
in the figure at right).
• When start-up is complete, a control property [0002] will appear.
• Then five seconds later [FFFF] will appear.
(3) Set the rotary switch SWU3 (labeled A in the figure at right) back to "0."
The start-up process is complete, and the settings for such items as
clock, peak-demand control, schedule, and thermistor settings can now
be made.
*1 If the start-up process has already been completed, [FFFF] (instead of [EEEE]) will appear when the rotary switch
SWU3 is set to "F."
(3) System configuration procedures : Multiple system
1. Set the dip switches and rotary switches.
(Switches on the MAIN circuit on the main unit* AND the MAIN and SUB circuits on all sub units)
System configuration diagram
Setting the switches on the main unit
MAIN circuit
(1) Set the dip switch SW2-8 to ON. (an external
water temperature sensor) (labeled A in the
figure at right)
(2) Set the dip switch SW2-9 to ON. (multiple unit
control)(labeled A in the figure at right)
SUB circuit
Nothing needs to be changed.
Refer to "Dip switch settings table" (page 69) for
further details.
Make sure the address of the MAIN circuit on the main unit is set to "1" (labeled B in the figure above) and that the
address of the SUB circuit on the main unit is set to "51" (labeled C in the figure above).
The address of each SUB circuit should equal the sum of the MAIN circuit address on the same unit and 50.
