Dedicated room controller

PCD7.L79xN compact room controller
The series of compact room controllers is particularly suitable for
simple systems which involve heating and/or cooling.
The PCD7.L79xN series room controllers include the control
of presence and setpoint values, the room temperature sensor
and the valve or flap control in a single housing. The preconfig-
ured regulation and control program is part of the basic soft-
ware and can be parameterised via the network communication
and adjusted to the individual requirements.
Efficient installation
The compact room controller can be installed directly on a wall
or in a flush-mounted box. A junction box is not required, which
also simplifies the installation process.
Thanks to the plug-in housing (electronics) on the mounting
plate with the terminals, it is easy to exchange the device with-
out complex and fault-prone rewiring.
