I was trying to figure out when the furnace would come on to satisfy the following conditions:
wake : 73 degrees at 6:15AM, Night temp is setback to 62 degrees.
I programmed the fan speed to high hopefully overriding low fan speed period and giving immediate high fan and high heat.
I did not want the furnace to come on 90 minutes prior to set time (factory default for smart recovery on). I had a Honeywell thermostat installed until about 5 hours ago. We were certain that furnace came on 60 minutes prior to the set time. This does not agree with the manual stating a 90-minute default setting for smart recovery.
I am not sure the how the furnace will react with commanding high fan nor do I know when it will come on.
Will the furnace come on with low fire and high fan?
When will the furnace come on since smart recovery is off?
You (any of you that read this) may ask why we set the furnace up this way. Both my wife and I are light sleepers. When the furnace comes on, we are awakened long before we want to get up. We hope that the furnace comes on about 30 minutes before the set time and reaches the desired set point of +11 degrees in about 35-40 minutes. This will get the Master Bath and Bedroom to about 67 degrees (there is a 6 degree differential between the thermostat location and the temperature in the MBR) for showering and dressing. We have this setting only two days a week when my wife rises early for work.
The Carrier installer was familiar with the Infinity thermostat but not entirely. He had to call a friend to figure out how to set fan speeds and had no idea about the time the furnace would come on to warm to the set point.
Hope that makes sense.
Thanks for the help.
