5. Product description
5.1 - General
Controller ESYS S4965V3250 is intended to be used for industrial DC-fan applications. It is made for fan assisted, direct
burner ignition applications. The ESYS controller operates on 230 Volts, 50-60 Hz and can drive a gas valve and a DC-fan
with PWM control input.
The High Limit protection protects the ESYS from overheating the application and is based on a low voltage switch input
(normally closed).
The controller can operate in normal heating mode or in Test Mode:
-
normal heat demand can be generated by a 230V switch input or is given by special command using external
communication port of the ESYS by the appropriate software
-
special Test Mode is initiated through external communication port, too
The S4965V3250 burner control operates in conjunction with VK41xxFxxxx or VK41Vxxxxx 1 to 1 premix gas control.
