Setting the compressor output limit to activate the relay – Max sp.
This parameter allows you to set the upper output limit of the outdoor unit compressor in % of
its maximum output. If the compressor output exceeds the
Max sp.
for
Delay
minutes, the
relay with the
Limiting
function will be activated. You can set the value
from
0.0 to 99.0%
by 1%
.
Setting the duration of the condition for changing the relay state – Delay
This parameter allows you to set the period of time in minutes for which the compressor
output must exceed the
Max sp.
to activate the relay with
Limiting
function. You can set this
value
from
0.0 to 99.0% by 0.1 minutes
.
Relay logic
This menu allows you to set the switching logic of the selected relay. Relay switching logic
can be direct or inverse.
Direct
-
The relay contact is closed if relay function is activated (and vice versa)
Inverse
-
The relay contact is opened if relay function is activated (and vice
versa). (This applies only when the module is turned on.)
Setting the indoor fan control mode
This menu allows you to set the indoor fan control mode or set the fan speed directly using
the FMD-01 module. You must connect this module to the SCMI-01.4 unit via wiring that
connects the corresponding VE+ and VE- terminals on the SCMI-01.4 unit and FMD-01
module.

Setting the Constant Fan Speed – Fixed
This menu allows you to set the constant speed of the indoor fan using the additional FMD-
01 module. The speed can be set
from 30 to 100%
of the maximum fan speed. After setting
the required fan speed, short press the
ENTER
key to confirm the set value. Then you have
to select the indoor unit fan operation mode. If the
Co – compressor
is selected, the indoor
fan runs at the set speed only if the outdoor unit compressor is running; if the
Fa – fan
is
selected, it runs only if the outdoor fan is running; if
On
is selected, it runs continuously at the
set speed regardless of the outdoor unit operation. Use the ▼/▲ keys to select the desired
mode and long press the
ENTER
key to save the set outdoor fan speed and mode.
Automatic fan speed control Auto 1
In this option, the indoor unit fan speed is derived from the outdoor compressor speed in the
1:1 ratio. This means, for example, that at 50 percent of the compressor speed, the indoor
fan runs also at 50 percent of its maximum speed.
Automatic fan speed control Auto 2
In this option, the indoor unit fan speed is derived from the outdoor compressor speed
at the
preset ratio
. The ratio of the indoor fan speed to the outdoor compressor speed can be set
using the
USBCommunicator
program or using the ▼/▲ keys on the SCMI-01.4 unit
display in the range of
60 to 200 percent
. Press the
ENTER
key to save the set ratio into the
SCMI-01.4 unit.
