Control Specification (09/12 Class)
Function and Control
41
Detail
The frequency control is made within the following zones.
When a “stop current” continues for 2.5 seconds after rushing on the stop zone, the compressor
operation stops.
If a “
dropping
current” continues for 1.0 second after rushing on the
dropping
zone, the frequency is
reduced by 2 Hz.
Repeating the above
dropping
continues until the current remains in the
dropping
zone without
change.
In the keep zone, the frequency limit remains.
In the return / reset zone, the frequency limit is cancelled.
Limitation of current
dropping
and stop value according to the outdoor air temperature
1. In case the operation mode is cooling
The current drops when outdoor air temperature becomes higher than a certain level (model by
model).
2. In case the operation mode is heating
The current drops when outdoor air temperature becomes higher than a certain level (model by
model).

Freeze-up Protection Control
Outline
During cooling operation, the signals being sent from the indoor unit allow the operating frequency
limitation and then prevent freezing of the indoor heat exchanger. The signal from the indoor unit
must be divided into the zones as shown in the following diagram:
Detail
Conditions for Start Controlling
Judge the controlling start with the indoor heat exchanger temperature after 2 seconds from
operation start.
