The dreizler
®
burner control unit quattro pro allows a modulating overall control of marathon
®
burners and
boilers. No additional DDC regulation is required.
The dreizler
®
burner control unit quattro pro is a fully electronic, atmospherically controlled and dynamic
heater controller with universal application in burners and boilers. It modulates dreizler
®
burners with con-
figurable and adjustable PID control characteristics precisely and energy efficiently.

For more information about type-specific component characteristics, please see relevant manufacturer
documentation.
46.1 Description
The unit quattro pro can be used for all modulating dreizler
®
burners:
1) For burner model marathon
®
and GE-AR with modulating heating operation.
2) For dreizler
®
burners with motor speed control in two modulating, sequential burner positions.
The quattro pro control unit is mounted underneath the burner hood on the control panel, and completely
integrated into the wiring.
The quattro pro unit is used for:
1) Regulation of boiler temperature dependent on exterior temperature
2) Steam pressure control in steam boiler systems
NOTICE:
In general, the controller can be used in oil or gas powered heat generation systems.
The controller selects a three-point, step or two-point regulator via an external switch. An integrated ther-
mostat function controls the burner. Boiler temperature can be controlled continuously or via external tem-
perature sensors depending on weather conditions. A min. and max. limit for boiler temperature can be
configured. Additional functionalities can be added via a limit comparator (e.g. burner control depending on
external temperature, antifreeze setting, alarm for waste gas temperatures below a preset limit and result-
ing setpoint offset of boiler temperature).
NOTICE:
Furthermore, an automatic compression of the control parameters PID is also possible.
The controller is equipped with three inputs.
NOTICE:
All analog inputs can be set up with standard sensor and signals.
1. Analog inputs:
Input 1
- Boiler temperature
Input 2
- External setpoint or setpoint offset
Input 3
- External temperature
2. Binary inputs:
Input 1
- Operating mode changeover (modulating/two-stage)
Input 2
- Setpoint offset or switchover
