ATTENTION!
If a dual differential pressureless manifold is to be used, the return sensor
must be wired according to the following instructions (see Fig. 10:•).

with return sensor R2.1).

If the heating circuit contains a dual differential pressureless
manifold, the "A-R2" bridge on the WPM EconPlus must be re-
moved 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 the dual differential pressureless manifold. R2.1 must be
connected to terminal X3/R2.1. Fig. 10:•shows the correspond-
ing circuit diagram, in which the relevant bridges are depicted.
