The TR80 can operate in absolute or relative setpoint mode. In relative setpoint mode, the user
does not see the absolute setpoint, but has the option to shift it up or down, typically by +/-5
degrees.

Holding register 'User Setpoint' changes every time the user makes an adjustment on the wall
module. Master controller can write to this register to override the user selected setpoint. Mas-
ter controller can also reset the setpoint to the default value by using the 'Override Reset' regis-
ter explained before in the 'Device' section.
The master controller can disable user setpoint adjustment by setting the min and max regis-
ters to the same value.
'User setpoint limited' register is derived from 'User setpoint' but internally limited between
min & max settings. The 'User Setpoint' register value can fall outside of the min/max range, if
the master controller reduces the range by writing to the min/max registers, for example when
switching to unoccupied or standby modes.
