ZV1

PWM
PWM actual value input and target value output of PWM pump
(only in conjunction with VMS 70 solar pump unit)
R3/R4, R5/R6: Mixer outputs -> only one of the outputs (1 or 2) can be
switched. It is not possible to switch both outputs at once.
A VR 11 sensor must be used for the "COL" sensor; a VR 10 sensor must be
used for all other sensors.
Closing the "DEM" contact ends the heating demand for the relevant heating
circuit.
*1
: VR 70 configurations 2, 4, 7, 8, 9, 10 and 11 are currently not supported.
Two VR 10 sensors are included in the scope of delivery for the VR 70.
