Venstar 2441 Tstat Adapter issue after SmartHome replacement

[jeffl012]

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.

 

I solved this problem by deleting the thermostats from the ISY99, then added them back in after updating to ISY 3.3.2.
