16.3 outputs
In this menu, the signal type and the minimum speed can be adjusted for each
individual relay.
The signal type determines the way speed control of a connected pump is effected.
The following modes are available:
Adapter = speed control signal via a VBus
®
/ PWM interface adapter
0-10 V = speed control via a 0-10 V signal
PWM
= speed control via a PWM signal
Standard = Pulse packet speed control (factory setting)
Speed control of a HE pump is possible via a PWM signal / 0-10 V control. The pump
has to be connected to the relay (power supply) as well as to one of the PWM
outputs of the controller.
If PWM or 0-10 V is selected, the channels output and Profi le appear. In the
Output channel, one of the 2 PWM/0-10V outputs can be selected. In the Profi le
channel, PWM characteristic curves for solar and heating pumps can be selected.
Note:
When the minimum pump speed value adjusted in the Outputs menu
differs from the minimum pump speed adjusted in an optional function
that uses the same output, only the higher value will be come into effect.
Note:
If PWM, Adapter or 0-10 V is selected for an output, the adjustment range
for the corresponding minimum speed will extend to 20 … 100 %.
