The Compact Automatichas been specially developed for application in domestic central heating boilers, warm air furnaces or
water heatergas appliances.
The Compact Automaticisusedina systemcontextin conjunction with either a direct spark ignition(DSI),intermittent pilot (IP)
or Hot Surface Ignition control module and associated devices to provide programmed safe light--up and supervision of the main
burner of an appliance.
Subject to change without notice. Printed in the Netherlands.
Compact Automatic combination gas controls performall the
functions required to safely regulate gas flow to the pilot
burner and the main burner of domestic central heating
equipment,warm air furnaces, back boilers and water
heaters.
Compact Automatic combination gas controls comprise a
standard body to which a range of sub--assemblies are
factoryfitted to give various system options. This makes boiler
system design much easier as technical s pecifications and
unit dimensions are the same for all system options. Options
include servo pressure regulation,throttle valve, (switchable)
softlite, electricalhigh--low control and electricalor mechanical
modulationfor the complete range of control applications.
Compact Automatic combination gas controls are available in
line or low voltage versions and in three capacity ratings for
totalsystem versatility. Customer specific voltage models are
also offered
Compact Automatic combination gas control consist of a first
direct electric on/off operator for opening the safety valve of
class A or class B according to EN 161 and a second electric
on/offservo operatorvalve for opening the main valve of class
B, C or class D according to EN 161 and comply with the
additionalrequirementof D’ valves according to EN 297.
Compact Automatic combination gas controls are rated for
gas families MFD Group A (G 110), MFD Group B (G 120),
NaturalH (G 20), NaturalL (G 25) and LP (G 30).
All measurements are carried out under standard c onditions,
unless otherwise is indicated.

max
Automaticis the maximum pressure at which it functions
safely. However, the maximum operating pressure is limited
by the pressure range of the pressure regulator concerned
(see table 1.).
