•
1: Default. Relates to AO,2 (Set
Bus Temperature Feedback
[°C])
•
2: Relates to setpoint from
analog input terminals
•
3: Relates to AO,0 (Set
Temperature Setpoint Remote
[°C])
•
4: Associated with an analog
sensor connected to the
product and objects:
- AV,4 (Config Heat curve
offset (+/-) [°C])
- AV,5 (Config Heat curve
slope (+/-) [-]).
•
5: Associated with objects:
- AO,1 (Set Outdoor
Temperature Remote [°C])
- AI,1 (Data Outdoor Temp
Remote [°C])
- AV,4 (Config Heat curve
offset (+/-) [°C])
- AV,5 (Config Heat curve
slope (+/-) [-])
•
6 and above: Associated with
AO,3 to AO,8 (external sensor
inputs). See Automatic setpoint
scheduling.
For all options the actual
temperature setpoint used by the
algorithm can be read at AI,2 (Data
Act Temp Setpoint).
Configuration of analog input
must be made via Grundfos GO
Remote.

Temperature
Setpoint
Remote [°C]
W
Temperature setpoint via fieldbus.
Enabling:
•
Set MV,0 (Config Temp Setpoint
Source [Enum]) to 3
•
Set BO,0 (Set Control Source)
to 1.
AO,1
Set Outdoor

Data Act
Temp
Setpoint [°C]
R
Actual temperature setpoint used in
temperature controller.
If the limiter function is set to off, it is
the same as the actual reference
temperature derived from the set
reference temperature mode via
MV,0.
AV,4
Config Heat
curve offset
(+/-) [°C]
R/W
Adjusts the heat curve offset in
degrees Celsius. It is used when
MV,0 = 4 or MV,0 = 5.
AV,5
Config Heat
curve slope
(+/-) [-]
R/W
Adjusts the slope of the configured
heat curve.
1 equals the configured heat curve
and 1.5 equals the configured slope
multiplied by 1.5.
AV,6
Config
Default Temp
Setpoint [°C]
R/W
Fall back temperature setpoint in
case setpoint signal from bus or
sensor is lost.
Default: 40 °C.
