VWU 32E - VWU 50E
ATTENTION!
If a dual differential pressureless manifold is to be used, the return sensor
must be wired according to the following instructions.
Bild 1: WPM EconPlus circuit diagram with "A-R2" link cable between X3/B2 and X3/1 (must only be observed when a dual differential pressureless manifold is used
with return sensor R2.1).
If the heating circuit contains a dual differential pressureless
manifold, the "A-R2" link cable on the WPM EconPlus must be
removed from between X3/B2 and X3/1 and re-inserted between
terminals X3/1 and X3/2. In this case, the return temperature reg-
ulation is measured by temperature sensor R2.1, which is lo-
cated in an immersion sleeve in the dual differential pressureless
manifold. R2.1 must be connected to terminal X3/R2.1.
Bild 1: shows the corresponding circuit diagram, in which the rel-
evant link cables are depicted.
