the bus will be sent a progressively decreased value until the parameterisable
minimum setpoint value has been reached.
The parameters available are:
Action
: sets which of the two buttons will permit increasing the setpoint
value and which one will permit decreasing it. Options are “Left decrease,
Right increase” (default) and “Left increase, Right decrease”.
Setpoint Type
: it may be “Absolute” (default), “Relative (1-bit object)” or
“Relative (Float Object)”.
If the first is selected, the control object will be a 2-byte floating point object
and its value will correspond to the actual setpoint value to be sent to the
thermostat, being progressively higher or lower as the user touches the
control buttons. On the other hand, the permitted temperature setpoints
will be delimited by a
maximum value
and a
minimum value
,
defined by
the so-named parameters.

Absolute Setpoint Control
If the second option is selected (1-bit object setpoint control), the control
object will be binary, and it will throw a “0” to the bus whenever the user
asks for a setpoint decrement, and a “1” when the user asks for an
increment. How much it is incremented or decreased after every order is
defined through the
offset
parameter (which accepts values between 1
and 255 tenths of a degree), thus permitting a consistent self-update of the
label in the box after every user press, although the status object will also
admit the reception of feedback from the bus, i.e., the updated absolute
setpoint value sent from the external thermostat.
