(1) To assign the wired remote controller as the sub unit,
locate the address connector at the rear of the wired
remote controller PCB and disconnect it. Reconnect it to
the sub unit position.
(2) To assign the wireless remote controller as the sub unit,
locate the dip switch [S003] on the wireless receiver unit
PCB. Set the No. 3 switch to the ON position.
2-5. How to use the Test Run Setting
1. Set DIP switch [S003] No. 1 on the wireless receiver
unit PCB from OFF to ON.
2. All indicator lamps in the display section blink during
test run operation.
3. No temperature control is available during the test run.
4. After the test run, be sure to reset DIP switch No. 1
back to the OFF position and check that no indicator
lamps are blinking. Then remount and attach the PCB
cover as before.
To avoid placing excessive operating load on the equip-
ment, use this function only when conducting the test run.
