4.39 Minimum limitation of flow temperature
setpoint HK1 (TVmin)
Prevents too low flow temperatures.
Minimum and maximum limitation define the range within which the flow temperature
setpoint may vary.
Setting range Unit Factory setting
8...TVmax °C 8
TVmax Maximum limitation of flow temperature setpoint (setting on line 107)
The setting will make certain that the flow temperature setpoint will not fall below a
minimum level.

65 Minimum limitation of the flow temperature setpoint
70 Maximum limitation of the flow temperature setpoint
If the flow temperature setpoint demanded by the heating circuit reaches the minimum
limit and the outside temperature rises, the flow temperature setpoint will be maintained
at that limit, in other words, it will not be allowed to fall below it.
4.40 Minimum limitation of flow temperature
setpoint HK2 (TVmin)
Function and action of this setting are basically the same as with setting 105 described
above. The associated maximum limitation of the flow temperature setpoint is line 108.
Setting range Unit Factory setting
8...TVmax °C 8
