11-10. 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
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.
NOTE
●
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 sig-
nals for approximately 1 minute after the power is
turned ON. This is not a malfunction. (The signals
are received, but have no immediate effect.)
