switched on when a certain specific target temperature has been reached in the collector.
The "Program" menu allows you to set the following parameter:
• Target temperature for the collector.
7.2 Setting the pump control system
You can connect standard pumps and high-efficiency pumps (HE pumps). For these you
can set the following types of control system:
• 230 V block modulation (standard pumps)
• Analog control (HE pumps)
• Non-inverted PWM control (HE pumps)
• Inverted PWM control (HE pumps)
The "Basic settings" menu allows you to set the following parameters:
• P:33: Pump control on switching output R1
• P:34: Pump control on switching output R2
In order to keep the storage tank temperature as constant as possible, the solar circuit
pumps can be controlled by means of speed control. You can set the minimum pump
output with speed control between 30 % and 100 %. At 100 % the speed control will be
switched off.
The "Program" menu allows you to set the following parameter:
• Minimum pump output with speed control.
Switching outputs R1 and R2 switch only the pump supply. They are not speed-
controlled. Your minimum switch-on time is 5 seconds.
