Notes
• When using an analog signal, Central control Devices can not be used together.
Do not use signal cable over 1meter.
• Do not change a command too quickly.
Keep the command 30 seconds at least, otherwise it will cause a damage to outdoor unit.
• This function is very sensitive to supplied power.
So when using analog inputs, supply a constant-voltage by external power source.
