4.41 Maximum limitation of flow temperature
setpoint HK1 (TVmax)
Prevents too high flow temperatures.
Minimum and maximum limitation define the range within which the flow temperature
setpoint may vary.
Setting range Unit Factory setting
TVmin...95 °C 80
Tvmin Minimum limitation of flow temperature setpoint (setting on line 105)
The setting will ensure that the flow temperature setpoint will not exceed a maximum
level.
Maximum limitation is not to be regarded as a safety function as required with
underfloor heating systems, for example.

107 Maximum limitation of the flow temperature setpoint
If the flow temperature setpoint demanded by the heating circuit reaches the maximum
limit and the outside temperature falls, the flow temperature setpoint will be maintained
at that limit, in other words, it will not be allowed to exceed it.
4.42 Maximum limitation of flow temperature
setpoint (TVmax) HK2
Function and action of this setting are basically the same as with setting 107 described
above.
