The contractor who sold me a Rheem RAPMJEZ and RHKLM3821 air handler did not show up. This contractor told me i must have the 305 thermostat for humidity control. They have given me a new install date but keep blowing me off about giving it to me in writing, so I am on the verge of asking for a refund of my deposit.
On that note, I asked another contractor for a quote in the same system. He said this system does not allow humidity control.
My understanding was single stage systems don't do humidity control and 2 stage do but the first contractor insisted that the variable speed air handler controls humidity thru the 305 thermostat.
Can anyone explain to me who is right?
And if I don't need the 305 thermostat what is the point of buying this fancy thermostat?
