Armstrong 24 hour timers provide on/o pump control
according to preset operating times in order to increase
occupant comfort and improve the overall eciency
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 circu-
lating 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.
