Polarity of the power supply
When connecting the supply voltage, the polarity at
24 V AC and 24 V DC must be observed for all con-
trollers!
Functional earth
The controller is fitted with a functional earth con-
nection. It is used to improve electromagnetic com-
patibility (EMC)
We recommend you to connect the device to equi-
potential bonding in order to improve electromag-
netic compatibility.
Strain relief
Use the cable clips in the casing for all connection
cables inside the casing.
Cabling
Be careful so as not to kink or disconnect the meas-
uring tubes on the VAV air terminal unit.
