If I change my touchPro TStat mode to off I receive:
Line      1 (18:38:57):: RX: STR-[ ~HVAC,37,3,1$0D$0A ] :DEBUG<1262>
but if my TStat is in either heat or cooling and I send it a string turn off I receive the error. Any ideas why? My syntax is fine but it just don't work. All the other parameters for #HVAC action 3 seem ok except off (1).
