General description

The AHW(S) circulator is designed for circula�ng water in closed hydron

ic hea�ng systems or potable water systems.

Underﬂoor hea�ng s ystems, single and double-hea�ng systems, Ground

source heat systems, Boiler/Solar water hea�ng systems, Hot-water

recircula�on systems, Water circula�on for cooling air-condi�oning sys

tems, High temperature liquids recycle systems, One-pipe (series) sys

tems, and Two-pipe (parallel) systems

Benefits of installing an AHW(S) circulator

Eight diﬀerent modes of opera�on to suit diﬀerent system requirements:

•Easily selectable from the display.

•Modes include Sensor less demand-based control.

•Power consump�on clearly displayed.

AHW(S) circulators incorporate with variable speed control technology

with a AHW(S) motor, enabling op�mum energy eﬃciency and occupant

comfort, with built-in control algorithms that can adapt to con�nuously

changing system requirements with EEI ≤ 0.23 according to 2009/125/

EC Direc�ve. The AHW(S) Circulator features a user-friendly front-

mounted control panel and wiring box for ease of installa�on.
