Description/Design
* Wet rotor circulator with EC motor and
integrated automatic capacity adjustment
* Red button technology for very easy operation
* Graphic pump display with rotatable display
adjustable from US units(default) to metric
* Pump communication with IF (interface)
module that can be easily retrofitted: ideal
external operation
* Motor protection with electronic overload
protection (min/max voltage, max temp,
dry run, overload)
* Interface connection for extending built in
functions, for building automation (BA)
systems and external control
* Impeller with three-dimensional curved
blades and rotor can using carbon
fibre compound material
Equipment * Pre-selectable control modes Δp-c, Δp-v, Δp-T for optimum load adjustment * Pre-selectable speed for constant operation * Automatic setback operation for additional energy savings ("Autopilot") * Dual pump operation (master/slave, parallel and stand-by operation) * Programming via manual "red button" or Wilo IR (infra-red) module/monitor * Infra-red interface for wireless data exchange with IR- Module/IR-Monitor * BMS interfaces with optional IF (interface) module (LONworks and 0-10 Vdc) * Pump communication with IF (interface) module that can be easily retrofitted: ideal external operation * Fault lamp and contact for collective fault signal * Pump flanges - 2 bolt oval 1 ¼" and 1 ½" – 4 bolt 2" pump flange – 4 bolt 3" 125 # raised face ANSI |
Special features/Product advantages * Energy efficiency class A * Up to 80% power saving compared with constant speed circulating pumps * Maximum efficiency thanks to ECM technology |
