[3] Configuring the Settings

The settings must be set only by a qualified personnel.
<1> Making the settings
Use the LED display and the three push switches (SWP1 (↑), SWP2 (↓), and SWP3 (Enter)) to change the current
settings on the circuit board and to monitor various monitored values.
(1) Setting procedures

switches SW2 and SW3 have been set.

Normally an item code appears on the display.
(The figure at left shows the case where item code 1 is displayed.) Press SWP3
(Enter) to advance the item code.
↓
Press SWP3 (Enter) until the item code appears that corresponds to the item to change or
monitor its value.
The left figure shows a display example (Code 9 Outlet hot water temperature
setting).
↓
Press either SWP1 (↑) or SWP2 (↓) to display the value that corresponds to the
selected item.
The current setting value will blink.
↓
The left figure shows that the current setting value is "149."
To decrease this value to 140, for example, press SWP2 (↓).
Press SWP1 (↑) to increase the value.
<To change the settings>
When the desired value is displayed (140 in the example at left), press SWP3 (Enter).
↓
The displayed value will stop blinking and stay lit.
A lit LED indicates that the new setting has been saved.
* Pressing SWP1 (↑) or SWP2 (↓) will change the blinking setting value, but the
change will not be saved until SWP3 (Enter) is pressed.
If SWP3 is not pressed within one minute, the change will not be saved and the
display will return to the item code display mode.
Press and hold SWP1 (↑) or SWP2 (↓) for one second or longer to fast forward
through the numbers.
<To view the monitored data>
Press SWP3 (Enter) while the LED display is blinking (see step 3 above) to stop the
blinking.
* The values of the items that can only be monitored will not change when SWP1 (↑)
or SWP2 (↓) is pressed.
The display will stop blinking and stay lit after a minute, and the display will
automatically return to the item code display regardless of the type of values
displayed.
To change the values of other items, repeat the steps from step 2 above.
