Raypak 004675F Economaster II Boardpump Delay ADJ 3-10 Min

The Raypak Economaster II is a solid-state timedelay relay which regulates pump operation to optimize system efficiency and reduce operating
costs. It activates the pump as needed to support hot water demand, and shuts the pump down only after evacuating the boiler’s residual heat to the heating system or hot water storage tank.

The Economaster II saves money in several ways.  Electrical costs are reduced,

ELECTRICAL DATA Adjustable Timing: 3 to 10 minutes (Factory set at 7 minutes) Input Power (Primary): 24 VAC 50/60 Hz Input Signal (Controller): 24 VAC or 120 VAC Output (SPST Relay): Load - Up to 10 Amp-120 VAC Single Phase* Ambient Temperature: -67°F to +158°F * Motors larger than 3/4 HP and three-phase current require a contactor or motor starter equipped with a 120 VAC coil. SUGGESTED SPECIFICATION The Economaster II pump delay controller shall maintain pump operation until all usable heat from the combustion chamber is absorbed into the system or storage tank. It shall be adjustable from 3 to 10 minutes to facilitate fine tuning to the specific system.
