LU85020A1 - CONTROL AND REGULATION DEVICE FOR HEATING SYSTEMS - Google Patents

Abstract

The control and regulating device is intended for heating installations and consists of a housing receiving control and regulating modules, the control and regulating modules being correspondingly cabled and provided with insertion connections for corresponding connections of installation components. <??>The insertion connections are arranged in the form of sockets (1) under the control and regulating modules (2) inside the housing (3) in the region of a covered access opening (4). Under the sockets (1), there is provided in the housing wall (5) at least one external cable penetration opening (6) open towards the edge of the access opening (4). <IMAGE>
