Can anyone tell me if this is a decent stat, i was reading the manual on line seems to be a straight forward easy to use thermostat. The only thing i wonder about is the cycle rate, it states on an older furnace set to function 5 -5 on a newer 90 plus set to function 5-3. So this would be on 5 times per hour verses 3 times per hour ? Is there any benefit in using either setting. Thank you.
