bktong Posted March 30, 2010 Posted March 30, 2010 I'm thinking of buying the SH thermostats either 2491T1 or 2491T7 with the Insteon add-on and use it with my ISY. Do I really need 2491T7 with 7-day programming feature or I can get the 2491T1 and use my ISY to program it as a 7-day function? bktong
garybixler Posted March 31, 2010 Posted March 31, 2010 Hi My first thermostat was the 2491T7 and never used the programming feature in the thermostat as it seamed like an involved clumsy process to deal with. Instead I have found it very easy to create and change programs in the ISY to control the thermostat. So my second thermostat was the 2491T1. Gary
Sub-Routine Posted March 31, 2010 Posted March 31, 2010 AFAIK, the difference is the ability to add the humidistat to the 7-day and not the daily. Rand
bktong Posted April 1, 2010 Author Posted April 1, 2010 Gary and Rand, So, the answer to my question is get the 2491T1 (daily) and use ISY to program it as many days as I need as long as I don't need the humidistat function. Great thanks both. Billy
