1. APPLICATION
XTE 602 is designed for compensated / optimised control of two central heating zones in:
– commercial and public buildings
– schools
– residential complexes
2. FUNCTIONS
The principal functions of XTE 602 are :
• Compensated control of two heating zones by three-wire control of valves :
– optimisation of start and stop times of plants
– control of plant pumps (with delay in switching off) according current programme of event times
– minimum and maximum temperature limits of flows
– correction of heating curve origin
– self-adjusting
– Eco Off
• Timed programming: twentyfive 24Hour programs & two 7Day periods
• Programming with dates : twentyfive holiday periods ; winter season ; special period.
• Summer plant exercise of valves and pumps
• Automatic change GMT / Summer time
• Metering of degree-days
• Remote control for modifying current timed programmes
• Three On-Off inputs for signalling status or alarm
• Alarms for detector short or open circuits and for irregular operation of plants and components
• Optional C-Bus transmission of data with local PCs or remote Telemanagement PC.
To enable data transmission and Telemanagement use the “C-Bus Plug-in” type ACB 468 C1 or later
To communicate locally with a PC use the test Plug-in type ACX 232
