Designated use
t
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 invalidate 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
room temperature can be reliably measured.
Ensure there is adequate ventilation.
If necessary, use an external sensor (see section 7)
Attach base of housing to wall.
Close housing cover.
