Lux 722E Thermostat
I have a question that I would really appreciate some help. I found the
perfect Thermostat in my opinion for my specific setup. LuxPro PSP722E
Programmable MultiStage Thermostat (I have a 1 stage heat pump and Electric
Emergency heat). Can I add on someone else's out door sensor to this
Thermostat? I called the company and even though the stat handles
outdoor/indoor sensor, Lux does not manufacture a sensor unit(they said
"it is in development, we had a prototype but we were not happy with it.
We should have something out by next year"). This feature is very important
to me and this is why I need to know if I could use a honeywell sensor or
I know this post is getting kind of long, but let me just point out why I
think this stat may be the best (if it works as advertised). I had a robertshaw
non-Programmable that I just changed to a honeywell vision 7400D only to find
out that it is short cycling (sometimes compressor only on for 6 minutes Due
to a lack of "swing/differential" adjustment. Too bad because the unit looked
good!). I did my research and found the lux which does the following that
-1st and 2nd differential adjustment in .25F* increments.
-fan delay on heat or cool for both on and off (no more cold blasts).
-compressor locked out below a certain temperature (this is why I really need
the outdoor sensor, it gets below freezing and right now I have to manually
switch it to emergency heat).
-smart recovery locks out the emergency heat for the first 30 minutes and gives
the heat pump a chance to do its job(saves money)
The only other Thermostat that comes close to my needs is the Robertshaw 9720i,
but that is too expensive for me and I will still get cold blasts (no fan delay
for ON only for OFF). I will appreciate any help regarding the wiring of "any"
outdoor sensor to the LUX unit before I buy it. Thank you very much in advance.
