back to 34.5ºC. On the second button press, the value “9” will be 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 allows that Z41 updates
its own value to equal that from the external thermostat. Thinking of the
above example, if Z41 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
