jeffl012 Posted September 25, 2012 Posted September 25, 2012 I recently replaced my Venstar thermostat 2441V adapter. The replacement was sent to me by SmartHome due to the recall that caused the thermostat to sporatically set itself at a random temperature. Now the replacement adapter (v.95) does not work properly with the isy99. The isy seems to only be able to get the status of the tstat and cannot change its settings. Anyone else have this issue? I've updated the isy99 firmware to the latest beta, but it doesnt help.
alx9r Posted October 27, 2012 Posted October 27, 2012 I am having the same issue with one of four of my Venstar 2491T1E v.95. The isy994 is able to link, query, etc. Everything seems to work fine except it cannot change the 2491T's settings. The settings change in the ISY admin console, but they do not change on the Tstat's LCD. And, when I select device=>query in the admin console, the admin console reverts back to the original settings. Here is the strange part: - I have swapped the problematic thermostat with another identical known working thermostat. - The problem stayed with the location, i.e. it did not follow the thermostat specimen, the non-working location remained non-working, and the working location remained working. I suspect this might be an issue (or complex interactive problem) with one of the dual-band devices nearby, but I have not been able to confirm this.
Michel Kohanim Posted October 28, 2012 Posted October 28, 2012 Hi jeffl012 and alx9r, Please do ensure that you try our latest firmware (viewtopic.php?f=25&t=9612 ) and then let us know if you are still having problems. Please do ensure to remove the thermostat from ISY and then register it back after installing the firmware. With kind regards, Michel
