Dedicated room controllers

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 preconfigured
regulation and control program is part of the basic software
and can be parameterised via the network communication
and adjusted to the individual requirements.
Efficient installation
The compact room controller can be installed directly onto a
wall or in a flush-mounted box. A junction box is not required,
which also simplifies the installation process.
The plug-in housing (electronics) on the mounting plate with
the terminals enables an easy exchange of the device with no
complex and fault-prone rewiring required.
