    Smile honeywell TRH6300B thermostat.

    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.

    We just took one off the wall to upgrade so I saved the old one to give to a cousin who just needs a heat only stat. Was trying to download the manual but looks like Hokeywell's site is down.

    Appears to be the consumer version of the Focus Pro. 5 CPH is recommended for older and 80% furnaces, 3 CPH for 90+ furnaces which need longer run times to keep the efficiency up. I'd suggest doing so if you have a 90+ furnace or have hot water heat which also needs a little longer cycle.
