heating. For the heat recovery unit, units can run as the setting mode, no matter what the mode is running in.
• The power must be turned on for 12 hours prior to start-up to allow the crankcase heat adequate time to protect the
compressor.
• All indoor units on the same refrigeration system should have a common breaker to ensure that all indoor units are all
powered on during system operation.
• This indoor units can be controlled by wired controller and remote controller, but the unit have to connect a signal
receiver(RE-02) to use the remote controller.
