Armstrong Astro 2 hot water re-circulation systems
automatically circulate water through domestic hot water
distribution pipes. This helps to ensure that everyone in the
household has ‘instant’ hot water at the tap when they need
it, while also helping to conserve water and save water heating energy costs. All systems are assembled, wired, tested
and then shipped, ready for installation.

application
Armstrong 24 hour timers provide on/o pump control
according to preset operating times in order to increase
occupant comfort and improve the overall eciency
of domestic hot water re-circulation systems. The 24
hour timers are designed only for use with specified
Armstrong Astro series wet rotor circulators installed in
indoor hot water re-circulation applications.
Typical timer applications will cycle the pump at preset
times, allowing the user to select operation of the circulating pump during high peak usage periods in order to
decrease the delivery time to outlet fixtures and reduce
wasted water.
The timer control is programmable to ¼ hour intervals
within a 24 hour time frame utilizing a user-friendly
analog clock timer with hour and minute hands, two
directional arrows, and am/pm time setting.
