Hello, I have a bi-level house (1200sf/fl) with 3 kids and 2 adults residing. The reason I'm posting is I have just had a new system installed (Carrier 58MVB-80 and Edge TP-PRH with a temp sensor outside) and have noticed I can't get to the humidity programming settings on the t-stat. I realize the dealer may have locked it out and can easily fix that - so can I. Anyway, I'm uber-concerned about humidity control in this house because I have pianos on each floor as well has hardwood upstairs. Since the t-stat doesn't display the rh (which seems odd to me) I have to rely on the store-bought humidity sensors I have placed around the more expensive piano downstairs. Which t-stat would offer me better humidity/dehum. control/settings? The Edge or the Infinity? Any opinions or advice would be appreciated.
