BV,3
Config Primary DeltaT
Limiting ED
R/W
0: Disabled (default)
1: Enabled.
Enabling of primary differential temperature limiter. When enabled, the
differential temperature on the primary side is limited below the configuration
in AV,13 (Config Primary Delta T Limit [°C]).
AV,10
Config Supply Flow Limit
[m
3
/h]
R/W
Primary flow limit for hydronic balancing. The primary flow limit is enabled
BV,0 (Config Supply Flow Limiting ED).
AV,11
Config Thermal Power Limit
[kW]
R/W
Thermal power limit for the hydronic balancing. The thermal power limit is
enabled by BV,1 (Config Thermal Power Limiting ED).
AV,12
Config Return Temp Limit [°C] R/W
Return temperature limit for hydronic balancing. The return temperature limit
is enabled by BV,2 (Config Return Temp Limiting ED).
For heating applications the value works as an upper threshold.
For cooling applications the value works as a lower threshold.
AV,13
Config Primary DeltaT Limit
[°C]
R/W
Differential temperature limit for hydronic balancing. The differential
temperature limit is enabled by BV,3 (Config Primary Delta T Limiting ED).
The value is positive for both heating and cooling applications.
