SETPOINT_LOW_LIMIT (41505)
Minimal setpoint value which can be set by user, multiplied by 10. The default value is 180
(18
o
C).
6.6
SETPOINT_HIGH_LIMIT (41506)
Maximal setpoint value which can be set by user, multiplied by 10. The default value is 240
(24
o
C).
6.7
OFFSET_RANGE (41507)
Register contains a value which limits OffsetSetpoint value change multiplied by 10. The
value creates a range from
–
OffsetRange to + OffsetRange of possible Offset values which
can be set by user. The default is 30 (3
o
C).
Example:
Offset range value is 20. It means that user can change Offset Setpoint value from -2
o
C to
+2
o
C.
6.8
SETPOINT_STEP (41508)
The register contains Setpoint STEP value multiplied by 10. When the setpoint is changed by
arrow buttons locally from the Room Panel, single pushing of the arrow button causes
Setpoint change with the STEP value stored in this register. The setpoint can be changed in
the range determined by Setpoint Limits stored in Setpoint Low Limit and Setpoint High
Limit registers.
Setpoint STEP is also automatically adjusted to the Setpoint display precision. When the
register Setpoint Configuration bit 4 is
“true”
, the Setpoint value is displayed with one
decimal place. In that case Setpoint STEP is also adjusted to one decimal place.
Example:
Setpoint Configuration bit 4 is
“true”
and SetpointSTEP value equals 5. Actual Setpoint STEP
will be automatically adjusted to one decimal place, so the Setpoint STEP value will be
scaled to 0.5.
The function is active only when Setpoint Configuration bit 4 is
“true”
. Otherwise the
Setpoint value is displayed as an integer value and SetpointSTEP adjustment is
unnecessary. The default value is 10 (1
o
C).
6.9
OFFSET_NAME (41509)
There is one 32-bit register which can contain up to 4 characters (ASCII code) which can be
displayed as a text (name) on 14 segment display block together with the Offset Value
