Page 4: Introduction
1 Introduction 1.1 Intended purpose The SC400 and SC410 control elements including the SR400 and SR410 relays boards are systems intended to control the HVAC components (heating, ventilation, air-conditioning) in buses, for example for roof-top air-condition systems. They consist of a control element inte- grated into the dashboard (control device as an interface between human and machine) and an accessible relays board. -
