I recently switched from a pair of Nest Thermostats to Ecobee3 Lites (with six smart sensors). The improvement was dramatic. However, the best part was your circulation manager. It has significantly improved the comfort within our home. As I understand it, it uses the difference between the maximum and minimum of the selected sensors to control the circulation minutes (per hour). This is very nice, because the system will heat/cool based on the average temperature and circulate based on the differential. I would like to have the option to circulate based on the differential between comfort level and the minimum (for heating) and the differential between the maximum and the comfort level (for cooling). In this way, the circulation would be based on the comfort outliers. Is this possible?
On the surface, it appears as if either method will perform the same task. However, our HVAC system accompanies our wood stove. The wood stove makes the nearby rooms nicely warm and sometimes well above the comfort level. We like those rooms at that level. I want to ensure that the other rooms don’t fall too much below our comfort level. Basing the circulation on the low outliers for heating and the high outliers for cooling makes perfect sense to me.
