The Split Unit Gateway receives the setpoint value via this group object.
If when the Setpoint temperature limit is parametrized and activated the gateway receives setpoint values outside the
parametrized range, it sets the setpoint temperature to the upper or lower limit of the range.
If you activate Setpoint temperature limit while the current setpoint temperature is outside the setpoint temperature range,
the setpoint temperature will be set to the upper or lower limit of the range.
22
This object indicates the current setpoint value.
23
This object increases or reduces the setpoint temperature by intervals of 1 kelvin.
1 = Setpoint temperature increases
0 = Setpoint temperature decreases
If the temperature reaches the upper or lower setpoint temperature limit, further telegrams have no effect.
24
This object activates/deactivates the setpoint temperature limit
1 = Setpoint temperature limit deactivated
0 = Setpoint temperature limit activated
If you activate Setpoint temperature limit while the current setpoint temperature is outside the setpoint temperature range,
the setpoint temperature will be set to the upper or lower limit of the range.
The setpoint temperature limit is activated after download.
However, activating the Forced operation priority takes the setpoint temperature limit into account.
