Stratos GIGA2.0-B 32/1-19/1,1-R1-S1

High-efficiency pump in close-coupled design with EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2 and electronic power adjustment with a glanded pump design. The pump is configured as a single-stage low-pressure centrifugal pump with flange connection and mechanical seal. The Stratos GIGA2.0-B has been predominantly designed for pumping heating water (acc. to VDI 2035), chilled water and water-glycol mixtures without abrasive substances in heating, air-conditioning and cooling systems.

Design ...-R1-S1:

• Single-stage low-pressure centrifugal pump in close-coupled design with a one-piece shaft or split shaft (depending on the pump type), including a foot on the pump housing
• Flange and housing measurements according to EN 733
• PN 16 flanges – drilled according to EN 1092-2
• Pressure measuring connections (R 1/8) for mounted differential pressure sensor (version ...-R1 without differential pressure sensor)
• Pump housing and motor flange with cataphoretic coating as standard
• Mechanical seal S1 recommended for water-glycol mixtures with glycol proportions up to max. 50% by volume and a fluid temperature of -20 °C up to max. +90 °C to +110 °C and also if there is oil in the water-glycol mixture.
• Connection voltages:
  • 3~440 V ±10% 50/60 Hz; 3~400 V ±10% 50/60 Hz; 3~380 V -5% +10% 50/60 Hz
• Compliance with electromagnetic compatibility without additional measures
  • Interference emission for residential environment according to EN 61800-3:2018
  • Interference immunity for industrial environments according to EN 61800-3:2018

Control modes:

• Constant speed (n-const.)
• Constant temperature (T-const.)
• Constant differential temperature (dT-const.)
• User-defined PID control
• Only possible with differential pressure sensor:
  • Permanent, automatic power adjustment to system requirements without setpoint specification Wilo Dynamic Adapt plus (factory setting).
  • Needs-based volume flow optimisation of the feeder pump through connectivity and communication between multiple secondary pumps (Multi-Flow Adaptation).
  • Constant volume flow (Q-const.)
  • Variable differential pressure (dp-v) with the option to set the nominal duty point Q and H
  • Constant differential pressure (dp-c)
  • Differential pressure control (dp-c) to a remote point in the pipe network (index circuit evaluator)

Functions:

• Selection of the field of application in the setting assistant
• Operating modes of twin-head pump/two-pump system: Main/standby operation
• Switchover between heating and cooling mode (automatic, external or manual)
• Ability to save and restore configured pump settings (3 restoration points)
• Fault and warning messages shown in plain text with advice on resolving the issue
• Integrated full motor protection
• Only possible with differential pressure sensor:
  • Heat quantity measurement
  • Cooling quantity measurement
  • Adjustable volume flow limiter using the Q-Limit function (Q_min. and Q_max.)
  • Pump automatically deactivates when no flow rate is detected (No-Flow Stop)
  • Efficiency-optimised parallel operation for dp-c and dp-v

Version:

• 4 configurable analogue inputs: 0-10 V, 2-10 V, 0-20 mA, 4-20 mA and commercially available PT1000 (only on two analogue inputs); +24 V DC power supply
• 2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, heating/cooling, manual override (uncoupled from building automation), operation lock (key lock and remote operation configuration protection))
• 2 configurable signal relays for run signals and fault messages
• Slot for Wilo-CIF modules with interfaces for building automation (BA) (optional accessories: CIF modules Modbus RTU, BACnet MS/TP, LON, PLR, CAN)
• Wilo Net as a Wilo system bus for communication between Wilo products, e.g. Multi-Flow Adaptation; dual-pump operation
• Automatic emergency operation with definable pump speed for exceptional circumstances, e.g. bus communication or sensor value malfunction
• Rotatable, graphic colour display (4.3 inches) with one button manual operation level
• Bluetooth interface via Wilo-Smart Connect module BT
• Use the Wilo-Assistant app to read and set operating data and –among other things– set up a commissioning protocol through the Bluetooth interface
• Integrated dual-pump management (twin-head pumps are prewired) when using 2 single pumps as two-pump unit (connection via Wilo Net)
• Cable break detection when using an analogue signal (in connection with 2 – 10 V or 4 – 20 mA)
• Time stamp for error/warnings and historical operating data
• Continuous operating data memory
• Standard condensate drainage holes in the motor housing (closed upon delivery)
• Air vent valve on the lantern
