The Uponor Wirsbo A3030004 is setback compatible and has a LED display with easily readable red, yellow, and green indicators that show when power is emitted, when heat is being called for, and when switches are closed. Power input for the Uponor Wirsbo A3030004 is 24 VAC. To receive your order quickly, be sure we receive it by 5 p.m. EST/2 p.m. PST, and we’ll ship it the same day you order it!
Caution: Because the end switch circuit is not protected from over current, install a 1-amp fuse. For proper operation, ensure there is a separate transformer load on the end switch. Do not connect the SB, R, C terminal to the ES terminal with the same transformer.
