[Hai-users] can't get RC80 to talk to my OmniLT

[Brad]

Dan, 

If you're sure your wiring is ok and all connections made are good,
including the one's made with the crimps on the pig tail that plugs into the
thermostat.

If you have an ohm meter, I would double check the comm wire from the white
plug that goes in the thermostat to the LT. 

Twist two wires together at the LT end, and then see what you get with the
meter at the thermostat end on the same two wires you twisted together.

Then test the other pair. 

 

The addresses are important if you have more than one thermostat hooked to
the LT. Each has to have its own address.

Well off hand, I can't think of anything else to try.

Ok, set the LT to auto heat/cool and the RC80 to auto changeover (no fan
with heat) but still not getting any control.  I also put the display
options back to 1 which is default.  Basically everything is back to
defaults.

 

Hmm.. is there any other troubleshooting I could try?  

 

-        Are "addresses" with the omniLT irrelevant?

-        Do I need any zones setup for the thermostat with the OmniLT?
Currently I do not have any - just my regular burglar zones.

-        Is there some other configuration on the Omni that I might be
missing?  I've read through the manual several times now - it seems like
it's pretty straight forward.

 

Thanks,

dan

Just for Grins, I would change the thermostat in the OmniLT type to Auto
Heat/Cool. Simply because that is the type thermostat it is. Not necessarily
how you are going to use it.

 

The Display Option set to 5 disables the built in program in the thermostat.
So it does not override what the Omni tells it to do.

Thanks brad.  I have the omniLT thermostat 1 set as "heat only" for my gas
forced air furnace.  I also have the thermostat set to #13 "heat only (fan
on with heat)"

 

Address of the RC80 is 1

Communication mode of the RC80 is 1 (OmniLT)

Display Options is set to 5 (Fahrenheit am/pm time format non-programmable)

 

I'm not sure what non-programmable means or if it is significant.  None of
the other settings seem to matter.  I'm pretty confident with my cabling.

 

Weeeeird stuff.   At least I got my phone going just now!  Just had to
actually turn it on in the phone menu.

 

Any help with the thermostat stuff is appreciated.

 

Thanks again

dan

Did you set the correct thermostat type in the Omnilt?

Hello, I just purchased an OmniLT kit.  Everything is going pretty well but
I can't get my OmniLT and RC80 communicating.  I have the red and black
wires spliced together at the thermostat.  I'm using green, black and yellow
which connects into the corresponding connectors on the LT.  Everything
seems in order.  I'm using communication mode 1 and I have tried address 0
and 1 although the Omni LT doesn't seem to use addresses so maybe that
doesn't matter.

 

I am not able to trigger the fan from the OmniLT control panel or read the
temperature.  Basically I have no interaction it seems.  If anyone can offer
some tips or ideas that would be really appreciated.

 

Thanks,

Dan Wheeler
