Remote setpoint, relative (REL)

7.5.1 Basic type and suitable setpoint adjusters
You can only configure a relative setpoint adjuster for basic type A.
It acts on the Comfort and Economy room temperature setpoints.
Suitable setpoint adjusters are the QAA27 room operating unit (−3...+3 K) or the
BSG21.5.
7.5.2 Activating the function
The function is activated by setting the identifier of an input as "Remote setpoint
adjuster, relative" (REL).
The relative remote setpoint adjuster can only be activated for room temperature
control, basic type A, and always acts on controller 1.
7.5.3 Measuring range
The setpoint adjuster's range must be 1000...1175 Ω = –3...+3 K.
7.5.4 Setpoints
The relative remote setpoint adjuster acts on the lower Comfort setpoint (SET MIN)
and the upper Comfort setpoint (SET MAX).
Therefore, the dead zone X dz between Seq1+2 and Seq4+5 remains the same as
the dead zone X dz for the permanently preselected setpoints.
