Which/Whos control you use.

Tekmar outdoor sensor boxes have a space built right in for a second sensor. Their (same for Taco) regular 10K thermister snaps right into a set of plastic teeth, right below the included Block. Run a 4 or six wire T-stat wire and have a ball! Chris

    Sensors in Parallel

    I have a job that has two boilers. I was wondering if I would be able to wire the outdoor sensors in parallel? Boilers are same model.

    If you don't have time to do it right, what makes you think you have time to do it over?
