(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 wire-
less receiver unit PCB. Set the No. 3 switch to the
ON position.
11-5. 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 dur-
ing 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 indi-
cator lamps are blinking. Then remount and attach
the PCB cover as before.
To avoid placing excessive operating load on the
equipment, use this function only when conducting
the test run.
