h ot wat e r r e- c i rcu l at i o n s yst em a ppli c at i o n s 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 from the factory, ready for installation.
High temperature switchpoint1 : 105°f (40°c) ± 10% Clock/timer: 12 hour analog clock with am/pm indication Timer settings: Individual mechanical toggles for each 15 minute interval over 24 hours Manual override: 3 position slide switch, on/off/auto Approvals:
