Notes:
1. If the operating mode is Auto, the setpoint cannot be changed.
2. The Mini-Splits have varied setpoints ranges (64
o
F – 90
o
F in cooling and 50
o
F – 86
o
F in heating).
In the event that a value outside of the available setpoint range is sent from the BMS via
iTM
,
the indoor unit will ignore the out of range setpoint command (however, in the above case, the
iTM
can send the cooling setpoint value and heating setpoint value of only 64
o
F – 82
o
F.)
Even within the available range of setpoints, for example, if the setpoint value of “61
o
F” is sent
from the BMS, the return value from the indoor unit could be “60
o
F” due to the
Fahrenheit/Celsius conversion. Therefore, when the setpoint is controlled from the BMS, do
not continue to send the setpoint until the sent value matches the return value.
3. Fan, Dry, and Auto are not supported.
4. Eco Mode command is also sent to models without the function. Subsequent command
processing is processed by the indoor unit.
5. Unit types other than those supported display an invalid value (0)
6. Unit types other than those supported are off
