Single-button operation for the following functions is also included as standard:
Pump on/off: Operating mode selection: lead/standby operation, parallel operation (peak-load switching with efficiency optimization) (Accessory: 2× IF module Stratos required). Regulation mode selection: dp-c (constant differential pressure), dp-v (variable differential pressure), dp-T (temperature-controlled differential pressure), via IR monitor/stick, Modbus, BACnet, LON, or CAN. Q-limit for restricting maximum flow rate (adjustable via IR stick only). Control mode (fixed speed setting). Automatic de-rating operation (self-learning). Setpoint and/or speed setting. Graphical pump display for showing the following values in horizontal and vertical module layout: operating status, regulation mode, differential pressure and/or speed setpoint, fault and warning signals, operating mode. Twin-pump synchronous motor with ECM technology, maximum efficiency and high starting torque, automatic de-blocking function, and integrated full motor protection. Fault indicator lamp, potential-free collective fault signal, wireless communication via Wilo IR (infrared) monitor/stick control and service device, IR (infrared) interface. Socket input for Wilo IF modules Stratos with interface for building automation (BA) or twin-pump management (Accessory: 2× IF module Stratos — Modbus, BACnet, LON, CAN, PLR, Ext.Off, Ext.Min, SBM, Ext.Off/SBM or DP). Pump casing of cataphoresis-coated cast iron, impeller of glass-fiber-reinforced plastic, stainless steel shaft with metal-impregnated carbon bearings. Flange versions: Standard equipment for DN 32 / DN 65 pumps: combination flange PN 6/10 for counter-flange PN 6 and PN 16 (flange PN 16 to EN 1092-2), standard equipment for DN 80 pumps: flange PN 6 for counter-flange PN 6 (designed for PN 16 to EN 1092-2). Special version for DN 32 to DN 80 pumps: flange PN 16 for counter-flange PN 16 (to EN 1092-2).
