sent, and the setpoint will become 34ºC.
And so on until an offset of “-10” (setpoint of
15ºC) is reached. From that moment, any further presses on the decrease button will re-
send the value “-10” and the setpoint will remain at 15ºC.
Important
:
the control object for the floating point relative setpoint control has its
Write flag enabled with the intention of permitting the reception of feedback from
the thermostat, which may reset or modify the status of the offset for any reason at
any time. This feedback lets Z41 Pro / Lite / COM update its own value to equal
that from the external thermostat. Thinking of the above example, if Z41 Pro / Lite
/ COM receives the value
“0” after having the user performed three presses on the
increase button (therefore, after having been sent the value
“1.5” to the bus), it will
happen that on the forth press the value sent will be
“0.5” and not “2”
.

Note
:
the parameterised setpoint type becomes transparent to the final user, as
the aspect of the on-screen box remains the same in all cases. In addition, the
setpoint status object is always a 2-byte floating point object and will represent, in
any case, the absolute value of the current temperature setpoint
