1. RPM CONTROL
The A1 and A2 outputs can be operated using RPM control. For the
following control types:
• 230V block modulation
• Analogue signal
• PWM signal
The value set limits the minimum control value. The minimum pump RPM
can be configured in a range between 30% and 100%. If the value of
100% is set, then RPM control is switched off.

2.2 HE PUMPS
The temperature difference controller in the solar circuit controls the so-
lar pump RPM in a range between 30% and 100%. The minimum pump
RPM can be configured in a range between 30% and 100%. If a value of
100% is set, then RPM control is switched off. The pump RPM given by
the controller is indicated as “nSoll” in the curves shown overleaf.
• Control of the solar circuit pump via PWM signal
The controller emits a PWM signal at connection O1 for the control of
PWM pumps (jumper position PWM). Base frequency = 2 kHz, approx.
12 V, approx. 5 mA.
• Non-inverse PWM control
Non-inverse PWM control: Target RPM 0-100% equates to PWM 0-100%.
Used for solar applications.

2. INDEPENDENT CONTROLLER
This function is set to output 3 and can be configured for the following
functionality.
• Cooling
• Heating
• Difference regulator
The temperature sensor for the temperature source can be selected as
desired.
• Cooling
If the temperature measured exceeds the target value, then output A3 is acti-
vated until the temperature measured drops below the target value hysteresis.
