Installation problem After installation, I couldn't get the humidifier to work. I connect the yellow wire to the humidistat and furnace's electronic board HUM connection. I can get a 24V signal (verified by multimeter) every time the furnace blower starts up. I hooked up the terminal connection, and plugged in the power supply. But both the fan and solenoid valve don't kick in, when the blower starts. Please help!! The connection I made is: HUM to humidistat, humidistat to humidifier, and humidifier to COM (as instructed by Carrier 58STA manual). Water is connected and verified, but since solenoid valve never kicked in, the panel is still bone dry. Something strange too. If I leave the humidifier plugged in , the furnace sometimes won't start. So I have to unplug it last night to keep the house warm. Any help is appreciated

    I have the same problem. It seems that the blower needs to be energized and the stat calling for heat with th burner running. Can this be the case? I don't have enough call for heat, so the humidifier never comes on.

    All the above steps were done. We replaced the IAQ Vision Pro thermostat. All wiring was checked. All programming was checked.

    The humidifier will NOT turn on. Carrier furnace is new as of June 2007.

    Humidifier is Honeywell HE360A,B. Is there a compatibility problem?

    Humidity is set at 40% and frost at 8. Tom

    I have a HE360A and a IAQ Vion Pro Honeywell thermostst. The machine will not turn on. I found a note on compatibility in the IAQ manual saying that the HE365 is compatible, but the 360 is NOT listed. Caan you tell me if it will not work with the IAQ Vision Pro?

I WOULD CHECK TO SEE IF YOU HAVE ENOUGH V/A OUT-PUT ON TRANSFORMER. I DONT KNOW IF YOURS CAME WITH ITS OWN TRANSFORMER. IF IT DIDNT YOU SHOULD HAVE A MINIMUM OF A 40 V/A RATING STAMPED OR PRINTED ON THE EXISTING TRANSFORMER. IF THE TRANSFORMER IS EXTREAMLY HOT ... YOU MAY NEED A 75 V/A TRANSFORMER WITH THE SAME VOLTAGES. INCREASING THE V/A CANNOT DAMMAGE ANYTHING IT JUST GIVES YOU MORE POWER WHEN EXCESIVE CONTROLS AND WIRING ARE ADDED TO A HVAC LOW-VOLAGE (24v) CIRCUIT. IF YOU LIKE YOU CAN CALL ME AT 727-363-7071. I AM A RETIRED HVAC&R CONTRACTOR WITH 45 YEARS EXPERIENCE. I HATE THE NEW SENSORS THEY HAVE TO ACTIVATE THESE NEW HUMIDIFIERS. I USE TO WIRE THE HUMIDIFIER TRANSFORMER (SUPPLIED WITH HUMIDIFIER) TO THE LINE (110V) SIDE TO THE LOW SPEED ON YOUR BLOWER MOTOR. THAT WAY THE ONLY THING THAT INTERUPTS THE CICUIT IS THE HUMIDISTAT. YOU NEVER WANT THE HUMIDIFIER TO RUN IF YOUR SYSTEM IS NOT "CALLING FOR HEAT". NEVER TRY TO ENERGIZE THE WATER SOLENOID THROUGH YOUR HEAT WIRE(USUALLY SMALL THE WHITE WIRE) FROM THE THERMOSTAT. THIS WILL RESULT IN BURNING YOUR HEAT ANTICIPATOR OUT ON THE T-STAT.

Honeywell HE200 humidifier only runs when fan/heat are off

It sounds like the wiring for the humidifier may not be correct. The solenoid valve, which controls the flow of water to the humidifier, should be wired to the humidistat and the transformer, not to the furnace or fan. It is possible that the bottom wire of the solenoid is connected to the wrong terminal on the transformer or humidistat, or that the top wire is connected to the wrong terminal on the humidistat. I recommend consulting the installation instructions for your specific humidifier model, or consulting a professional HVAC technician to verify the correct wiring.

Hello, in order to turn your humidifier on with the furnace the 120 volts coming from your humidifer you must hook it up to a step down transformer, then the transformer will provide 24 volts to you humidistat and solenoid valve. So you need a wire from the HUM on your control board to transformer primary side and a wire from neutral on the board to primary side of transformer. Then you need low voltage wire from secondary side of transformer to humidistat from humidistat to humidifier.

Wired a new 360 through Hum blew 3amp fuse. How to wire so it doesn't blow fuse. Have open EAC and EAC2.

Review figures 5, 6 and 7 on the installation instructions and compare with how you wired your installation.
The red wires are not used if you use a mechanical humidistat, (are used with electronic humidstat - supplies 24 volts and go to "hot", "commod" on humidstat). Yellow wired to "Hum" whether electronic or mechanical humidistat used.
If using sail switch or current sensing relay, cuts into one of the yellow wires. - One yellow goes directly to humidisat, then comes out of other side of humidistat & runs to to relay (or sail switch), and comes out of relay (or sail switch) and runs back to humidifier.

A breakdown diagram of parts etc above.

Shows you the HE360A.
To me it sounds like it is wired incorrectly, the solenoid should NOT get too hot at all. The PDF above shows wiring data.

Wiring issue with the Honeywell HE360A Humidifier

Maybe I can help. this is 24v so it doestn't matter which wire goes where so here goes. 2 wires from humidistat go to furnace, split one of the wires(not both) so they reach the yellow wires on the humidifier. with marettsconnect one of the split wires to one of the yellow wires. do the same to the other split wire and yellow wire. what you should get is one wire from humidistat to furnace then one wire from humidifier to humidistat and one from humidifier to furnace. hope this helps

Humidistat installation question

I suppose you are looking at the do-it-yourself model. Depending on the wire that is run up to you Regular Thermostat from your furnace. You may have to run a seperate line for the Humidistat. A digital thermostat that does Humidity and Temperature is recommended. Or you could just place a Humidistat near the furnace room. A wiring diagram will come with the Humidifier discribing the different ways to wire it.
