XTE 602  

C1

  

Eng.

• Optimising compensator

 

– compensated and optimised control of two heating zones

• Power supply 230 V AC (or 240 V AC for UK market); DIN rail mounting

• Communication systems :

 

C-Ring

 for exchanging data between local controllers.

– C-Bus

 :  XTE 602 Telemanagement optional; 

 

to enable Telemanagement use the “C-Bus Plug-in” type

 "C-Bus Plug-in" type ACB 468 C1 or later

,

 

to be ordered separately as accessory.

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
