⑤ If the unit or controller needs to be replaced, it’s necessary to confirm
whether matched resistance is connected to the unit or controller. Configure
the new unit or controller according to the confirmed results.
⑥ If any change is made to the unit, for instance, adding or reducing units,
controller must be restarted. 3min after controller is restarted, start up the
Intelligent Billing Eudemon to restart self-check and configuration.
⑦ Please power on the controller 3min after the unit is debugged and
communication is normal. Do not enable software self-check and
configuration until the controller is energized for 3min.
⑧ If unit is found with errors, e.g. communication error, system conflict, project
code conflict, etc., it is necessary to eliminate errors for the first time to
ensure normal calculation.
⑨ Please install UPS power supply for the controller and make sure the
controller is always energized so as to ensure normal calculation.
⑩ If the KWH meter has communication error, please eliminate the error
immediately. Otherwise calculation result will be incorrect.
⑪ If the indoor unit has communication error for a long time, please confirm
whether it is power-off or damaged. If power connection is normal and the
