On the Honeywell panel HZ311, the Heat LED light is red.

Customer Question

Customer: On the Honeywell panel for the HZ311, the Heat LED light is red. Does that mean the furnace should be heating because it's not. The heat ducts out of the furnace are not warm. Three zones in house, all 3 fan lights are green. Thermostats set on "Heat".
JA: Thanks. Can you give me any more details about your issue?
Customer: Should the Heat LED be red or green?
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to HVAC Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?
Customer: OK
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

Good afternoon, I am Kevin, one of the tech's here on Ja.

You have a HZ311 panel, but no zones are calling for heat?

Customer: replied 1 year ago.
The 3 thermostats are all set to Heat and Fan On. LED lights in 2 Zones are green, but Heat Light is Red. Ducts are cool.
Expert:  Kcrand36 replied 1 year ago.

If your fan switch is set to on in then the thermostats are telling the fan to turn on. What is your temperature in the home and what is your setpoint?

Customer: replied 1 year ago.
Zone 1 Set to 66 Reading 60
Zone 2 Set to 66 Reading 56
Zone 3 Set to 66 Reading 54
All Fans set to on
System has been on for 8 hours
Expert:  Kcrand36 replied 1 year ago.

I think we need to look at the furnace......... what do you have for a furnace?

Customer: replied 1 year ago.

Expert:  Kcrand36 replied 1 year ago.

is the furnace running?

Customer: replied 1 year ago.
about 8 years old...been working just fine....no heat coming into ducts....usually feel warm ducts....
Expert:  Kcrand36 replied 1 year ago.

your temperatures are very close to "night set back" common settings. Please verify on each thermostat, proper time and temperature. If possible, place all stats in a "hold" status for 68 degrees or what ever you feel comfortable at..

Expert:  Kcrand36 replied 1 year ago.

even if power is lost and stat loss of power, it may reset time. Proper time is critical, it may think it's very early in the morning, instead of afternoon.

Customer: replied 1 year ago.
Bryant Plus 90 hi efficiency gas furnace
Expert:  Kcrand36 replied 1 year ago.

ok, try increasing temperature for one thermostat, and let's put all thermostats "fan switch" in the "auto" position.

Customer: replied 1 year ago.
All are on Auto set at 66 Hold Permanent Heat
Expert:  Kcrand36 replied 1 year ago.

have you set the fan switch to auto?

Customer: replied 1 year ago.
Expert:  Kcrand36 replied 1 year ago.

ok, you are going to remove the cover for the zone panel. find a small piece of wire to be able to connect one terminal to another. I will intsruct you the terminal connections.

Customer: replied 1 year ago.
Whats the zone panel?
Expert:  Kcrand36 replied 1 year ago.

the hz3111

Expert:  Kcrand36 replied 1 year ago.

the hz311 is your zone panel. it distributes power to open and close zone dampers installed.

Customer: replied 1 year ago.
I have no wire
Customer: replied 1 year ago.
What does it mean that the Heat Light is Red? Heat on? or Heat Off?
Customer: replied 1 year ago.
Kevin...????
Expert:  Kcrand36 replied 1 year ago.

well, the heat on, might just be the status of the thermostat. but in order to determine wether it is a panel or furnace problem, you need to have a small piece of wire. there might even be a piece of wire not used on the zone panel. It may be wrapped around other wires. if it is not connected, then lets try to use this. you will have to cut and make sure you have good connection at each end.

Customer: replied 1 year ago.
All the wires are connected...this isn't working....I guess I will have to call the emergency guy in town...outside temps are freezing and inside still reading high 50s low 60s....
Customer: replied 1 year ago.
thanks for trying Kevin
Expert:  Kcrand36 replied 1 year ago.

don't give up yet.

it may be something very simple.

Expert:  Kcrand36 replied 1 year ago.

Expert:  Kcrand36 replied 1 year ago.

Customer: replied 1 year ago.
House is cool ing down...all thermostats below 60 now
Expert:  Kcrand36 replied 1 year ago.

hang in there. it's gotta be here now.... because I can't imagine a total fault of the zone panel.

might just be a tripped limit switch.

Customer: replied 1 year ago.
Where would that be? Its a Bryant 90 Plus Ultra High Efficient on front panel
Expert:  Kcrand36 replied 1 year ago.

upright? you have duct work on the top and ductwork entering on the bottom or side?

Expert:  Kcrand36 replied 1 year ago.

upright is the question.... I need the answer to tell you where to find the panel to remove.

Expert:  Kcrand36 replied 1 year ago.

take a picture mike if you can and post it using the paper clip icon .......... that will move us along quick.

Customer: replied 1 year ago.
Upright
Ducts coming off side
Customer: replied 1 year ago.
Wheres the paperclip icon...is it the Add files link?
Expert:  Kcrand36 replied 1 year ago.

ok. there may be two panels one to the top and one at the bottom.

, and yes, the add files link will work.

Expert:  Kcrand36 replied 1 year ago.

my goal is to get you heat for the night ok? you may need help tomorrow, depending on what we find, but I really want you to have some heat tonight!

Expert:  Kcrand36 replied 1 year ago.

I'm in CT, I would like to say I would be there in 1 hour, but I'm sure your just a little further than that.

Customer: replied 1 year ago.
Working on picture
Expert:  Kcrand36 replied 1 year ago.

ok Mike, no problem. I'm here to help.

Customer: replied 1 year ago.
Panel with LED lights
Expert:  Kcrand36 replied 1 year ago.

I am suspecting that your furnace is not working. It may have a code to tell us the issue. so we will need to follow through with that that diagnosis. it should not take long .

Expert:  Kcrand36 replied 1 year ago.

ok, got the Hz311 ..........let's look at the furnace.

Customer: replied 1 year ago.
At least the fans are working, but circulating 50 degree air
Expert:  Kcrand36 replied 1 year ago.

let's get to the furnace...... asap.

Customer: replied 1 year ago.
Panel pick and inside
Customer: replied 1 year ago.
You with me Kevin?
Expert:  Kcrand36 replied 1 year ago.

ok good on the pics. that lower panel will have the circuit board, that may tell us the secret. when you take off the lower panel, it should have a circuit board, the door it self may activate a switch that if the door is removed, will shut off the furnace. You will have to push this switch in by hand to get the code on the board. Try it a couple of times, so you get the same code every time, by pressing the door switch in and letting it out with time in between.

Customer: replied 1 year ago.
Is this the circuit board with wires and switches? No switch on or off with panel off...don't think it shuts off when panel is off....
Expert:  Kcrand36 replied 1 year ago.

no, that looks like the gas valve section. I'm looking for where the circuit board is, there would be low voltage wiring connecting from the zone panel to the circuit board of the furnace.

Expert:  Kcrand36 replied 1 year ago.

most likely the panel below where you took that picture.

Customer: replied 1 year ago.
Is it in one of the two circular glass covered "caves" on the bottom of this picture?
Customer: replied 1 year ago.
Running out of time...no heat yet...forecast is for below 0 wind chill tonight....all thermostats still reading below 60 degrees
Expert:  Kcrand36 replied 1 year ago.

yes, I' m not seeing any circuit board, so it must be below the two circular window panels.

Expert:  Kcrand36 replied 1 year ago.

keep in mind, you told me you were going to get someone else out tomorrow.

Our goal is to get your heat working tonight!.

Customer: replied 1 year ago.
Nope...I am calling my local heating tech at 6 PM EST if we cannot get the heat pumping...pipes and stuff will freeze if we don't get heat into the house pretty soon, esp given the forecast for tonight....
Customer: replied 1 year ago.
Kevin...does the Red heat light mean the heat is on even if the ducts are cool?
Expert:  Kcrand36 replied 1 year ago.

ok. so do you want to continue or are you calling the heating company?

Customer: replied 1 year ago.
at 6 pm EST time....tell me what to do please...
Expert:  Kcrand36 replied 1 year ago.

it depends on how it is set up. I'm assuming based on your symptoms that your furnace is not running. it maybe be a simple reset or it may be something more serious. I am in CT, so I am in the same time zone. where are you located?

Customer: replied 1 year ago.
Fans are working....how do I re=set?...Michigan in the same time zone
Expert:  Kcrand36 replied 1 year ago.

the fans have nothing to do with the system. either they are "time delayed" after a heat call or as your previous statements that you have placed them in "auto" mode.

Customer: replied 1 year ago.
How do I re-set the furnace? Turn it off and on, like a re-boot on a computer?
Expert:  Kcrand36 replied 1 year ago.

your problem is with the furnace. most likely a safety control has tripped.

I'm trying to help you with this, but it does require some hands on. If your not capable of this, then I would suggest to call a local dealer.

Expert:  Kcrand36 replied 1 year ago.

yes, turning it off and on will reset, but not necessarily solve the problem. you will need to see the codes on the board help you diagnose the issue.

Customer: replied 1 year ago.
how do I de trip the safety control
Expert:  Kcrand36 replied 1 year ago.

we need to find out the code first ok?

Customer: replied 1 year ago.
Where will I see codes? Numbers? Lights?
Expert:  Kcrand36 replied 1 year ago.

I told you , on the control board. lower panel.

Customer: replied 1 year ago.
Inside the glass circle panels???
Customer: replied 1 year ago.
OK time to call it....I need heat tonight. Been on with you 2.5 hours....I know you tried your best, ***** *****
Customer: replied 1 year ago.

Expert:  Kcrand36 replied 1 year ago.
