The KNX control RAMSES 712 controls the temperature in residential
and officespaces. It can be used as a continuous or two-point control for
heating and cooling systems (e. g. for radiators and cooling surfaces). It
has an integrated bus coupler.
The RAMSES 712 can be installed in a flush-mounted socket without
housing. The room thermostat is suitable for dry rooms only.
The regulations and instructions in the ZVEI/ ZVEH Handbook must
be observed to ensure that the bus lines are installed and the units
are commissioned in a professional manner.
Tampering with, or making modifications to, the device will invali-
date the warranty.
Position the temperature control on an internal wall,
at about eye level (for temperature measurement).
Avoid draughts or heat emission.
Do not install in flush-mounted sockets connected to the mains
electricity supply.
Installation in a flush-mounted socket
Remove control from base of housing (release
fastener) and install in a flush-mounted socket.
Attach the integrated temperature sensor in such a way that the
