Q-Limit Max
The additional control function “Q-LimitMax” can be combined with other control functions (differential pressure control (∆p-v, ∆p-c), cumulated volume flow, temperature control (∆T control, T control)). It makes it possible to limit the maximum volume flow to approx. 10 % – 90 %, depending on pump type. When the set value is reached, the pump is controlled on the characteristic curve along the limit – never beyond.
CAUTION
Property damage caused by frost!
When using Q-LimitMax in non-hydraulically balanced systems, some areas can be inadequately supplied and freeze!
- Carry out hydronic balancing!
NOTICE
The Q-LimitMax function is not available with an external setpoint specification of e.g. 0 to 10 V.
