Field Setting by Demand Adapter

Parts and Function

2.2.1 Demand Operation by External Input

If you want to reduce power consumption, perform "demand operation" to forcedly restrict the
outdoor unit capacity using a demand adapter (optional: KRP58M2).
[Types of demand operation]
Demand 1
Demand 2
Demand 3
* Forced
Compressor startup control
Defrosting operation (during heating)
Oil return operation
* This is operation to return refrigerant oil to the compressor
Also in cases other than above, the compressor gradually
reduces the frequency and then stops.
Field Setting
A demand adapter (optional: KRP58M2) is used to make the following setting for outdoor
units.
1) Setting of demand operation by external input
2) Setting of low noise operation by external input
DS1, X81A and X800M cannot be used for RZQ200 and 250C models.
For the connection of "sky-ene-cut," use the connector (X14A) on the control board.

When this setting intervenes the operation mode as shown on the below, the compressor
stops after the operation mode as shown on the below completes.
Control as shown
Input of forced stop
when load is low and the compressor continues operation for
a long period of time with a low frequency.
Transmission connector (X80A)
Connect to the connector (X6A)
on the outdoor unit control PCB
Terminal specification: 5 poles, M3 screw
Demand and low noise input terminal block (X801M)
·
Connect control input from a remote area (central
supervisory board, timer, etc.).
