Additional functions:
- Interfaces: Control input "Overriding Off", "External pump cycling", analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for control mode (DDC) or for remote setpoint adjustment, analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for actual value signal of the pressure sensor, Infrared interface for wireless communication with the operating and service unit Wilo-IR Stick/IR-Monitor, plug-in position for Wilo IF-Module for connecting to the building automation, configurable, potential-free fault and operating/ready message, interface for dual pump communication
- Three-phase AC motor with frequency converter
- Integrated dual pump management
- Adjustable time interval for pump cycling
- Integrated full motor protection
- Different operating modes for heating mode (HV) or air-conditioning mode (AC)
- Access disable
- Different operation levels: Standard / Service

 Commissioning | Commissioning Glanded pumps | 2219391 | |
High performance is our strength. Entrust the Wilo commissioning-service with ensuring a smooth process when implementing new systems in your installations. We will happily accompany you throughout the commissioning process of our products and support you step-by-step. You will benefit directly from the advantages of our products and their performance in operation. Our qualified service technicians will familiarise you with all strengths to guarantee a safe and optimal start. Why you should take advantage of our commissioning expertise: The pump is part of a complex supply system, that is why the focus of professional installers during commissioning is primarily on the higher-level system technology. However, the optimal pump settings – as a part of the overall system – are crucial for energy consumption and therefore for the efficiency and operational reliability of the entire system. The advantage of using professional installers is that they hand over a system to the customer which is energy efficient from the start and they do not have to acquire detailed knowledge of each control and pump series for this. This significantly reduces both energy costs and pump wear. The commissioning service provided by the Wilo service also includes instruction of the responsible building service engineer. | |||
