System-wide functions
When outdoor-temperature-compensated control with gradient characteristic is used, the re -
turn flow temperature is limited to a fixed value by equating the 'Base point for return flow
temperature' and 'Max. return flow temperature' (PA1, 2 ) parameters.
Functions WE Configuration
Return flow sensor RüF1/RüF2 1
1.0
CO1, 2, 4 > F03 - 1
KP (limiting factor): 0.1 to 10.0
Return flow temperature limitation with P
algorithm 1)

1)
If the controller indicates CO5 > F00 - 1, any access to the return flow, flow rate and capacity
settings is locked.
Parameters WE Parameter level: value range
Return flow gradient 1.2 PA1, 2 : 0.2 to 3.2
Return flow level 0.0 °C PA1, 2: –30.0 to +30.0 °C
Base point for return flow temperature: 65.0 °C PA1, 2: 5.0 to 90.0 °C
Max. return flow temperature 65.0 °C PA1, 2, 4: 5.0 to 90.0 °C
or
Parameters WE Parameter level: value range
Return flow temperature, points 1 to 4 65.0 °C PA1, 2: 5.0 to 90.0 °C
To ensure the preset return flow temperature limit can be kept, make sure that the following
conditions are met:
−
The heating characteristic is not adjusted to ascend too steeply.
−
The speed of the circulation pumps is not set too high.
−
The heating systems have been balanced.
