Installation of Universal Mixing
Valve Controller HM 80
Select the installation location so that the HM 80 can
communicate without interference by radio with the
CM67RFMV operating unit and is protected against humidity
The HM 80 can be installed in one of 2 ways:
• Wall installation
• DIN rail installation
Four 4.0-mm holes for installation are located on the HM 80.
Take the 161.5 mm installation height of the
HM 80 into account. If the HM 80 is installed at a
severe angle, the transformer must be on top to
allow for ventilation.

Installation site CM67RFMV
Specify the installation site of the CM67RFMV.
Install the CM67RFMV using the wall holder (b) or the
desk holder (a).
The CM67RFMV is a radio-controlled device.
Installation should therefore be carried out in an
open room. A minimum distance of 30 cm from
any metal objects and distribution boxes is to be
observed and a minimum distance of 1 m from
other electrical devices such as radio, TV, etc.
