2.1.6 Connecting a circulating pump to the core module
Different types of wiring must be implemented depending on the type of pump:
High efficiency pump with control line (PWM / 0-10V)
On high efficiency pumps with an additional wired control line, the speed control is implemented via the
additional connection for the PWM or 0-10V signal.

❒ Connect the power supply for the high efficiency pump to output “Pump 1” of the core module
❒ Connect the PWM cable of the high efficiency pump to the corresponding “PWM / 0-10V” port
➥ Make sure that the cables are configured correctly (polarity) in accordance with the connection diagram
of the pump!
❒ Set control of the pump in the relevant menu to “Field pump / PWM” or “Field pump / 0-10V”
High efficiency pump without control signal
It is not possible to control the speed when using this type of pump. The use of a line regulating valve (e.g.:
Setter balancing valve) is recommended.
