• Large comfort ashcan for simple emptying and long emptying intervals ash boxes
• Speed-controlled, quiet induced-draught fan with function monitor for maximum operational reliability
• Automatic ignition
• Serial automatic WOS-technology (Efficiency Optimisation System) for maximum efficiency and automatic cleaning of the heat exchanger
• Double protection system for maximum burn back protection
• Energy-saving drive for double protection system and WOS
• External suction modul fitted in the return line in any position
• Integrated return feed lift function
• Room air-independent operation
• High-quality insulation

Control system P 3200 Touch

Microprocessor controls for optimising the combustion process through precise control of the boiler- and exhaust gas temperature, including actuators for primary and secondary air dampers, 7 ” color display for the representation of all important values and status messages with USB interface for updates; including lambdacontrol

Scope of delivery:

• Core module
  • 2 mixing heating circuits (outside sensor included) and
  • 1 speed-controlled pump output or change-over valve
• Hydraulic module
  • 2 speed-controlled outputs for pumps or switching valve
  • 6 sensor inputs
• Outside sensor
• DWH management with 1 sensor
• Contact probe for 1 mixing heating circuit

(2nd heating circuit possible via additional sensor)

Optional:

Control expandable to 18 heating circuits (wall enclosures) and total
