Problem 

Possible Cause 

Solution 

Thermostat is taking a 
long time to respond to a 
controller.  

The controller may be sending 
commands to a responder that is no 
longer in use. Commands for the 
unused responder are being resent and 
loading down the signal. 

Unlink any unused responders from the controller.  
HINT: If you are using home automation software 
such as HouseLinc, you can easily check scene 
membership and eliminate unnecessary links. 

If the above doesn’t work, perform a factory reset 
on the controller. 

Thermostat changed “all 
by itself.”  

Another controller, a timer or stray X10 
signals could have triggered 
thermostat. 

Monitor for recurrence and remove reason if you 
can determine what it is. If necessary perform a 
factory reset 

Thermostat is locked up.  

Excessive RF noise on may have 
caused a lock-up.  

Remove power to thermostat (by removing LCD 
“panel” from the back panel connected to the wall), 
wait 10 seconds and replace. 

Perform a factory reset. See 

Factory Reset.

 

If you have tried these solutions, reviewed this Owner’s Manual, and still cannot resolve an issue you are 
having with thermostat, please call the INSTEON Support Line at 800-762-7845
