Can't find terminal strip in old Bryant

Any help you can offer is much appreciated.

My husband, who is actually very handy, is in our basement working on installing an Aprilaire 500 whole house humidifier. Our Bryan air handler and heat pump are old at 16 years. He has everything connected except one major problem: the wiring.

He cannot figure out where the terminal strip is located. Is it such a simple unit that it is not accessible? We have researched the model Bryant Model fb4anfo36 and cannot find anything on locating the terminals. We cannot find a manual online.

Any advice besides hiring it out?

Thanks.

Welcome to the forums.
Thread moved to humidifier forum.

Most air handlers don't have a terminal strip. They use bare wire tails and wirenuts. Follow where the thermostat wiring enters in the air handle. That is the connection point. It's not always easy connecting a humidifier to a heat pump system. The most effective way to activate the humidifier is to use an airflow sensor or blower motor current sensor.

This should be the manual for your unit.

Drum humidifier maintenance.

W

windyc6 on Feb 02, 2018

Hi All, The product in question here will be a Honeywell drum humidifier that mounts to the "hot side" of the furnace but circulates the air from the hot side to the cold air (in) side for circulation. I installed this unit about 3 months ago and the install went fine and all seems to be working as expected and designed. The problem we are having is that the water tray that the drum circulates through gets really knarley and dirty in a very short time. Lots of calcium build up and other things growing in the water that can't be good for us. I realize that these things need to be cleaned regularly depending on water quality, but I am wondering is there anything we can do to help prolong the time between cleaning? We had a similar unit in our old home with the same problem and we eventually found some type of tablets that you could put in the water tray that seemed to help quite a bit. But we can't find the tablets anymore. I tried putting about a tablespoon of bleach in the tray but low and behold it makes the water tray foam up and then that foam builds up in spots and causes drips on the floor. So the bottom line and question is....does anyone have a good suggestion for handling this problem ? Does anyone know where any additives may be purchased whether they be liquid or tablet form, just as long as they work. Any suggestions would be appreciated. ThanksRead More

Honeywell HE360A Doesn't Shut off at Night - Nest 2nd Gen - Trane XV90

A

ajstan99 on Jan 20, 2018

Hi - I'm hoping someone can help me in diagnosing what appears to be an intermittent issue with my [B]Honeywell HE360A humidifier[/B] (duct mounted and plugged into a wall outlet for power). It's mounted to a [B]Trane XV90 two-stage heating, single-stage cooling[/B] furnace, and controlled by a [B]2nd generation Nest[/B]. A[B] 6AZU2 relay[/B] is also used. During the day, the humidifier runs only with the heat (as it's supposed to), but sometimes at night, after the thermostat automatically drops the temperature to 65 degrees for the night (11:00pm), the humidifier stays running (both water and fan) and I have to unplug it to get it to stop. Using the Nest app to turn off the humidifier doesn't work - the humidifier just keeps on running. After I plug the humidifier in again the morning, it works correctly, sometimes for a few days, before failing to shut off overnight. Here is my setup which was performed by the HVAC company that installed the furnace in 2013. I had everything working correctly on my old furnace and they just moved the relay and wires over to the Trane XV90. I think it worked fine for the first three winters, but I started having this problem last winter (2016-2017). [B]My connections are as follows from the furnace panel:[/B] BK (not used) W2 --- Nest W2 W1 --- Nest W1 R --- Nest RH G --- Nest G BC -- Two connections: Relay Connector #1 (coil side) and white wire to outdoor A/C unit Y --- Two connections: Nest Y1 and red wire to outdoor A/C unit YLO (not used) O (not used) The * wire from the Nest goes to Relay Connector #3 (coil side). The switch side of the Relay (Connectors #2 and #4) are connected to the two wires from the humidifier. [B]The Nest humidifier settings are as follows:[/B] Type: Hum Activate: Hum + Heat Fan: Activate Quiet Time: 11PM-4AM Also, fan is set to run from 7AM-10PM every day. So, my questions are as follows - I want the humidifier to run only when the heat is on (Stage 1 or Stage 2): 1. Are my Nest settings correct? 2. Is my wiring correct - especially with regards to the relay. Should I connect it to W1 instead of BC? 3. If #1 and #2 are correct, then how can I tell if the problem is with the Nest, the relay, or the humidifier? I'm assuming (maybe incorrectly) that if a wire was bad, the humidifier would have a problem turning on, not turning off. Thanks to all who read this, and any thoughts/ideas would be appreciated!Read More
