I just have replaced my single stage thermostat RITETEMP 8085 (http://www.ritetemp-thermostats.com/8085C.html) with a two stages Honeywell 8500D (http://www.homedepot.ca/webapp/wcs/stores/servlet/ProductDisplay?catentryId=33403&catgroupId=12133&j spStoreDir=HomeDepotCanada&catalogId=10051&action= 1&productId=33403&langId=-15&parent_category_rn=12133&storeId=10051&ddkey=mo stpop) and now the temp in my house(2 storey + finished basement aprox. 3000-3200 sqf) is not as even as it was when I had the RITTEMP installed.
Now upstairs is colder than downstairs or in the basement and the furnace (Goodman GMV90905CXA + Goodman CLQ Series 14 SEER 3 Ton A/C )is running just couple of minutes on low fire because the temp set point on the thermostat is reached very fast. I have setup the temp set point on the thermostat to 22.5C, after that to 23C and 24C. There was no change in the way the furnace works.
The contractor did setup the dip switches on the furnace's main board to reflect the usage of the 2 stage thermostat.
I am able to return the thermostat and get another brand or another type.
What will be your suggestion?
