I installed two Honeywell 8320s, one on our first floor (propane gas heat pump) and one for our second floor (electric heat pump w/aux. heat and emergency heat). My questions are:

1. Does anyone here use the "Circ" fan setting to randomly circulate air movement in their homes? Of course, hot air rises and cold air decends, so I would think circulating the air around would maintain room temperature, reduce the amount of time my furnance lights off and burns propane due to temperature drops. Also, is there any significant cost with the air handler fan coming on randomly with this setting?

2. For the upstairs electric T-Stat, will "Aux" come on in front of "heat on" when the system can't maintain temperature and requires assistance from auxilary heat? I want to be able to see when auxilary heat is engaged.

Question 1 Part a) Yes it is common and it works the way you said it does.
Question 1 Part b) No. (does "random" mean manual)
Question 2) I don't know what "in front of heat on" means.

Thank you for your reply, however, as service techs, installers and HVAC repair techs, do you recommend using the "Circ" setting?

In reference to the "Aux" in front of "Heat On", when your furnace comes on, just under the set temperature it displays "Heat On" on the display of your T-Stat. If auxilary heat kicks in, how do you know? Does it display "Aux" in front of "Heat On"?

What did you mean when you said "(does "random" mean manual)?" Lost me there.

I don't see a lot of people talking about the "Circ" function of the T-Stats, so I wanted to know if it's a recommended setting rather then just keepingn it at "Auto" to keep fuel costs down.

I have a Honeywell rth 6300 b 5-2 programmable. When the heat is off it says--HEAT OFF--the t-stat is off and won't control the heat cycle. When I push that button It changes to HEAT ON--and means that the t-stat will control the heat cycle (regardless of whether the furnace is actually blowing and burning). On mine if I want to circulate air I switch from FAN AUTO to FAN ON and HEAT ON or HEAT OFF.

I may be wrong on this, but I think for aux heat to come on the t-stat has to be set to HEAT ON or AUX HEAT ON if so configured.

Houston204 is the t-stat expert on this site, try a post with his name in the message title. When you say random do you mean manual random access, or that the CIRC mode works with a mind of it's own? To be honest with you, I don't know what the CIRC firmware program contains.

From information gained on this site and personal knowledge, FAN ON can improve comfort. All techs agree that FAN ON can improve efficient use of hot air, depending on the house ductwork. Some recommend it's use, some don't. If you have a return air grill placed in a high ceiling, and supply air registers low, it definitely works (for heat) and saves $$, cost of running the fan included. Wattage(electricity consumption)for a fan is low compared wattage or BTU to heat.

Thank you for the follow up.

Where I'm referring to is under the "Set To" temperature on the upper right side of the display. When the T-Stat calls for heat it literly says, "heat on" under the "set to" temperature. Of course I already have the T-Stat set to "Heat" on the left side of the display under "System". I was just wondering if "Aux" would pop up in front of the "heat on" indicator to let the homeowner know that their auxilary heat is being used. See Link below. Thanks.

Thanks for the demo,

Now I see what you mean. It allows you to program circ to run with or without heat depending on how you program the schedule? You might find it cumbersome to use at a set schedule, but you can always over ride it manually.

Does your owner's manual go into details about circ?

As far as the question "will circ show up on the screen when in circ...?" I would think so. Have you tried programming it yet, or are you going to use the energy star settings it came with?

By the way, I'm not a full blown HVAC/R mechanic, I'm a CSLB Licensed General Building Contractor (means in California I can do any trade on or in 3 story buildings or less, as long as my contract/work order includes at least 3 trades) My work in high rises has further limitations. It was set up that way a long time ago by the legislature, for the consumer, and the unions for work jurisdiction protection. ie the plumber does the gas, the carpenter cuts the sheetmetal man's holes, headouts and builds the furnace platform, the sheetmetal guy does the heat system, gutters, flashings, pans, etc.

We used to have tight unions out here. Not any more. I was a member of United Brotherhood of Carpenters and Joiners of America, Local 35 San Rafael. CA. for 9 years.

Been in business now 31 years. I usually sub out HVAC/R, but under my license, I could legally perform the work myself. Kind of funny, but that's the way it is.

Thank you
