“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 Lite
updates its own value to equal that from the external thermostat. Thinking
of the above example, if Z41 Lite 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.
