8.6.4.2. External Touch Display (ETD) control connection

The ETD is necessary to control the unit remotely (Except in case of integration to BMS), however the ETD is not
included with the unit, therefore it must be ordered separately (supplied as an accessory). This is so since a single
ETD can control up to 5 PURECLASS CL units.
The remote control is supplied with a 10 meter length cable, which can be replaced by a cable up to 30 meters (re-
commended control cable type. H05VV-F-4G 0.25). See details on the connection of the controller in the electrical
diagrams at the end of the manual.
The ETD has an electrical protection IP-20 degree, so it is reserved exclusively for indoor usage sheltered from
humidity.
Once the parameter setting is done, the remote control can be disconnected.
