For multipump modes, see Multipump modes, page 24.
Differential temperature
• Ensures a constant differential temperature drop across heating and cooling
systems.
• The pump will maintain a constant differential temperature between the
pump and the external sensor.
Constant flow
Note: Available for pumps with production code from 1838.
• The pump maintains a constant flow in the system independently of the
head.
• It is not possible to use an external sensor, instead, the pump uses its
internal sensor.
Constant curve
• The pump can be set to operate according to a constant curve, like an
uncontrolled pump.
• Set the desired speed in % of the maximum speed in the range from
minimum to 100 %.
