4. SETTING THE MODULE

The SCMI-01.4 control module can operate in the autonomous pressure (evaporation
temperature) control mode, autonomous temperature control mode for cooling, autonomous
temperature control mode for heating (simple heat pump) or in the slave mode. After
powering on, the module is initialized and then the display shows the default screen. For
example, if the module is in the slave mode and the outdoor unit compressor is stopped, the
display shows:
Inputs
Off 0%
When the compressor is running in the Cooling mode, the display shows:
Inputs
On C xx%
Character C indicates Cooling mode and xx represents the desired compressor
performance in percent. After switching to Heating mode (using the H/C input), the character
H is displayed instead of C.
In other modes, this screen is omitted and T1 and T2 temperatures, which are measured by
the resistance thermometers of the module, will appear first. The T1 sensor detects the
temperature of the indoor unit heat exchanger, while the T2 sensor detects the temperature
of the indoor unit supply air.
T1 xx.xºC
T2 xx.xºC
After pressing the ▲ key again:
