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.

'User Setpoint' (holding register 1200) 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. Master controller can also reset the setpoint to the default value by using the
'Override Reset' Refer
The master controller can disable user setpoint adjustment by setting the min and max
registers to the same value.
'User setpoint limited' (input register 202) is derived from 'User setpoint' but internally lim-
ited 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 regis-
ters, for example when switching to unoccupied or standby modes.
