Series description
CronoTwin-DL-E

Design

Electronically controlled glanded twin-head pump in in-line design with flange connection and automatic power adjustment

Application

Pumping of heating water (acc. to VDI 2035), chilled water and water/glycol mixtures without abrasive substances in heating, chilled water and cooling systems.

Equipment/function

Operating modes

  • Δp-c for constant differential pressure
  • Δp-v for variable differential pressure
  • PID control
  • Constant speed (n=constant)

Manual operation level

  • Green button and display

Manual functions

  • Differential pressure setpoint setting
  • Setting the speed (manual control mode)
  • Setting the operating mode
  • Setting the pump ON/OFF
  • Configuration of all operating parameters
  • Fault acknowledgement

External control functions

  • "Overriding Off" control input
  • “External pump cycling” control input (effective only in dual pump operation)
  • Analogue input 0 – 10 V, 0 – 20 mA for constant speed (DDC) and remote setpoint adjustment
  • Analogue input 2 – 10 V, 4 – 20 mA for constant speed (DDC) and remote setpoint adjustment
  • Analogue input 0 – 10 V for actual value signal from pressure sensor
  • Analogue input 2 – 10 V, 0 – 20 mA, 4 – 20 mA for actual value signal from pressure sensor

Signal and display functions

  • Collective fault signal SSM
  • Collective run signal SBM

Data exchange

  • Infrared interface for wireless data exchange with IR-Monitor/IR-Stick
  • Plug-in position for Wilo IF-Modules (Modbus, BACnet, CAN, PLR, LON) for connection to building automation

Safety functions

  • Full motor protection with integrated trip electronics
  • Access disable

Dual pump management (double pump or 2 x single pumps)

  • Main/standby operation (automatic fault-actuated switchover)
  • Pump cycling main/standby operation after 24 hours
  • Parallel operation
  • Parallel operation (efficiency-optimised peak-load activation and deactivation)
