13.2.1 Jumper X34 for analog voltage outputs X11 (OUT1) and X21 (OUT2)
The different types of high-efficiency pumps: Analog pumps with 0-10 V control and PWM pumps with 24V.
For each type of pump you have to adjust the signal at the heating controller.
The plug connector X34 is for the Jumper-settings. Use a jumper with a grid dimension of 1 inch. The termin-
als X11 and X21 can receive or export a different signal depending on the jumper position.
Note:
When using PWM-pumps for a voltage up to 15V, adapter-cables must be connected at the slots X11 and
X12.
These cables limit the output voltage from 24V to 15V.
Jumpersettings X34:
The male connector X34 serves for jumper-adjustments. Please use jumper with a contact spacing of 1 inch
(included in delivery of heating controller)

13.3 Rules of wiring for micronetwork with 1,2 or more heating
controllers
The boiler controller suplies the touch operating device and up to two remote controls.
• The order of devices in the bus-wiring is free. The station-numbers for the heating controller and the digital
remote controls have to be assigned uninterrupted .
• The number of heating controllers is independent from the numbers of the digital remote controls and in-
dependent from the numbers of boiler controllers.
• A double allocation is not acceptable.
• The maximum limit of bus-participiants is 16.
• The maximum length of a bus-cable is 200 metres.
• The maximum cable-length depends on:
– A solid point-to-point topology allows the fullmax. length.
– A star-topology does not allow the max. length.
– We recommend a twisted-pair cable , especially for long cables (e.g. in buildings) and if the cable runs pa-
ralell to other cables.
– Correct bus-connection resistance, which is always existing on boiler operating device.
For long cables or communication problems occur, a additional resistor with 120 Ohm has to be clamped
between wire A and B at the last bus-participant.
