* Speed controls description, standard and High Efficiency Pump
Optimised flow control and temperature difference between flow and return with variable pump speed via infinitely adjustable Triac
phase control or PWM signal for high efficiency pumps (energy saving pumps).
Triac Speed Control

Pump startup
Min rev pump
30%
dTMax dTFs
NB: Speed is regulated by a Triac modulated phase
control; therefore please check before modifying
values and commissioning:
Whether the pump can be operated using a
modulated phase controlled speed control.
That the minimum speed of the pump is equal
to or lowers than the regulated minimum
speed.
That the pump step switch is set to the
maximum output.
