setpoint (TVmin)
• Prevents too low flow temperatures
Minimum and maximum limitation define the range within which the flow temperature
setpoint may vary.

Maximum limitation of the flow temperature setpoint
The setting will make certain that the flow temperature setpoint will not fall below a
minimum level.
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. This may lead to exces-
sive room temperatures.
