• Easy to operate thanks to green button technology and display
• Integrated dual pump control system
• Integrated full motor protection (temperature sensor) with electronic switch-off

Type

Electronically regulated, flange-mounted, dry-running, in-line design with automatic power adjustment

Application

Pumping heating water (according to VDI 2035), cold water and water/glycol mixtures without abrasives in heating, air-conditioning and refrigeration applications

Equipment/function

Modes of operation

• Δp-c for constant differential pressure

• PID controller
• Manual mode (n=continuous)
   

Manual control panel

• Green button and display

Manual control

• Adjustment of flow value
• Adjustment of speed (manual switch-over)
• Setting of operating modes
• Pump ON/OFF setting
• Configuration of all operating parameters
• Acknowledgement of errors

External control

• "Priority off" control input
• External pump change" control input (only valid for twin pump operation)
• Analog input 0 - 10 V, 0 - 20 mA for manual control mode (DDC) and remote set point change
• Analog input 2 - 10 V, 4 - 20 mA for DDC manual operation and remote set point adjustment
• Analog input 0 - 10 V for pressure transmitter actual value signal
• Analog input 2-10 V, 0-20 mA, 4-20 mA for pressure transmitter actual value signal

Twin pump control (twin pump or two single pumps)

• Main/Standby operation mode (automatic switchover in case of fault)
• Main/standby operation, changeover between pumps after 24 hours
• Parallel operation of two pumps
• Parallel operation of two pumps (activation of second pump in peak load with efficiency optimisation)
