Prestige 2 IAQ wiring question

555 Views 3 Replies 2 Participants Last post by  beenthere
Hello. Here in OH my system is a heat pump with 3 electric strips. I eliminate strip heat as much as possible but there are occasions of bitterly-cold temps where they must be engaged. Historically, I isolated W1 from jumpered W2-W3 and took control via the t-stat when to engage W1 and W2, allowing the sequencer to control W3 (at least I'm guessing that's the correct terminology and how it's controlled). So now before I wire the Prestige I have two questions:

1. Would you suggest I remove the jumper to W3 at the air handler and connect it to U1 on the EIM, or would you consider it not a huge deal unless it runs xhours per month?

2. The manual states to wire a maximum of 2 sensors using S1-S4. I will definitely wire 2 sensors to measure Delta T but I also had the impression in my feeble mind that I could wire up-to two more temp sensors. Can you educate me on this?

Thank you

Thanks; I'll take advantage of U. But regarding sensors, since I'm a layman I thought perhaps I could wire a third sensor into a nearby register and monitor temperatures. For some reason I've been plagued with failures on this system in our [relatively] new home, stemming mostly from system leaks. Being inexperienced, I've come to rely upon supply temps from a nearby register as my indicator of a problem. Am I off base in my goal?
