I have the Carrier Infinity furnace and central a/c. Now that we're into summer, I have the Infinity thermostat set for the fan as "low" and I just use the 'hold' feature (e.g. no schedules).
The fan does NOT always run despite being set as "low". I've verified this by checking the thermostat: Mode: Cooling Fan: OFF A/C (or dehumidify): OFF
What I mean is that when it's not calling for cooling or dehumidify and the fan is set to "on" .. it does not run and shows as "off".
It's thrown a couple of code 41s in the advanced menu section. My installer is going to contact Carrier but it looks like it might be a couple of weeks.
The fan was running nonstop initially this winter when - duh - I forgot to change it to "auto".
Is this bit about having the fan to "on" for cooling and it not running "normal" ?? Is this going to cause me problems down the road with the a/c not performing ?
Thanks in advance.
