Introduction; How To Use The P-Comfort Knx - Gewiss CHORUS P-Comfort GWA9916 Programmierhandbuch

INTRODUCTION

The P-Comfort KNX performs the function of controlling loads on the KNX BUS, measuring and
indicating the instantaneous active power and energy consumed and/or produced by the system, and is
able to monitor up to five absorption limit threshold levels. The device is also fitted with a local relay for
directly controlling a load/circuit. It's installed on a DIN rail inside an electric board or junction box. The
device supports KNX Data Secure: this technology increases the security of a KNX installation both
during start up as well as during normal operation through the exchange of encrypted telegrams.
