Problem Possible cause and remedy
Changes to DIP switch settings are
not applied
The CompTrol Interface was still connected to the electrical supply
when the DIP switches were changed.
Remedy:
–
Cut o󰀨 the electrical supply to the CompTrol Interface by remov-
ing connector X1 from the CompTrol Interface before changing
DIP switch settings.
–
Then change the DIP switch settings.
–
Plug the X1 connector back in again.
The CompTrol Interface does not
initialize on the remote control bus
or
The indoor unit does not respond to
commands from the CompTrol
