Controls
The Worcester Greenstar FS CDi Regular fascia incorporates 
a combined temperature control and burner reset button.
The fascia also displays 2 operational status neons 
indicating the following:
•
 Mains on/lockout
•
 Burner on.
The mains on/lockout indicator also operate as fault finding 
diagnostics flashing in different sequences in the unlikely 
event of a boiler fault.
The Building Regulations Section L 2006 require a minimum 
level of controls to be installed on all heating systems, both 
on new build and refurbishment.
This would require:
•
 Room thermostat
•
  TRVs on all radiators, or at least those radiators in 
sleeping areas if not already fitted. Do not fit TRVs in the 
room in which the room thermostat is installed
•
 Time and temperature control for central heating
•
 Automatic by-pass.*
*Where requested – see installation booklet for further details.
