2-10. 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.
●
The unit does not receive remote controller signals
for approximately 1 minute after the power is
turned ON. This is not a malfunction. (The signals
are received, but have no immediate effect.)
