Taco SR503 Switching Relay combines clearly labeled PC board layout with advanced features that allow for total system customization. External indicator lights provide instant diagnostic feedback, making a snap of service calls or new installation start-ups. Taco SR503 switching relays are UL and CSA listed, use standard “ice cube” replaceable relays and are compatible with conventional and programmable thermostats.
While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
