Aprilaire 700 humidifier does not raise humidity.

It was installed 24hrs ago by a local AA certified contractor. 700 was their recommendation, initially we thought of 400 and then they called saying they think 700 is more adequate. Considering the price was the same I went along with it.



Initially it was set to auto. I set it at 5. My humidity in fact (it is cold in NJ) went down and is fluctuating between 25-27% on the hygrometer and 30% on the control panel. I set it to 7. Same. Midday today I switched to manual, keeping it at 7. No change. It is 25 at hygrometer and 29 at the panel.



I see the water going in, I can both hear it and see the water meter rotating.

I also hear the fan.

It is installed on the return.



What gives?

Come Monday I will call the contractor but it will be warm Monday so I am not sure how they will troubleshoot.

Program 5808w3 loop 3 as ZT12

I have a Vista 20p. I'm trying to get a 5808w3 smoke loop 3 (low temp) to program as zone type 12. I can't get it to work correctly. I can program it as zone type 8 and it works but I want it in as ZT 12.



Does anyone know if this can be done?



Thanks.

Excessive heat rise in an Amana AMVM960603BX modulating furnace

Temperature in the supply plenum rises above what the manual says is the max...pretty quickly. I've been trying to figure this one for many months and it's a mystery. Any insight much appreciated.



Communicating modulating Amana AMVM960603BX furnace with three zones controlled by an EWC Ultra-Zone board. One communicating 'stat, two regular 'stats. The dampers all work. Manometer says total static pressure is less than 0.5 no matter how many zones are open (summing measurements at fan intake plenum after filter, before AC coil with the coil panel open and a hole drilled thru the cover plate, and after the coil). For example, with all zones open and fan speed about 1200 cfm it's about .15 before the fan, about .22 before the coil, and about .12 in the supply plenum. And my anemometer says about 1200 cfm airflow thru the supply plenum. Looks like the air is moving as designed.



The manual for the furnace say an OK temperature rise is 20 to 50 degrees. But no matter how I set the zone board to stage the furnace, the supply plenum temperature gets above 120 degrees within five minutes of heat-on call (return air is about 70 degrees). It looks to me like the core problem is the fan speed is set according to the gas flow: For example, if gas is 100% of maximum then the fan runs at 100% of the speed chosen on the dip switches; 50% gas means 50% fan, and so forth. That is, I can't tell it to run the fan faster than the gas percentage.



What works OK is to set the dip switches so the furnace fan is at max for any given gas percentage, and set the target target temperature on the zone board at 120 degrees and then have the zone board overtemperature cutoff at about 130 degrees. The zone board calls for max heat at startup until the supply plenum gets near 120, which means the fan runs fast. Then the fan and the gas slow down, but there's not enough air to keep it below 130%, so the zone board cuts off the furnace while keeping the fan running, waits three minutes, and starts the cycle over again.



So, I'm letting the supply plenum temperature go 10 degrees above what it says in the manual, but on a cold night, say 10 degrees outside, the thing can barely keep up because the gas is off almost as much as it's on.



And it bugs me to be using a safety to operate the system.



Anyone know of a way to jigger the furnace control board to give me a way to set the fan speed separate from the gas flow?



Sorry for the long post. Thanks!



The problem:

Trane rtu with ddc - no heating no draft motor

Am wondering if anyone has dealt with an issue where the Trane rtu yhc048 will not cycle on the heating during auto cycle test (or at any other time) due to the venter motor contacts not closing in the ignition control board? I checked all the burner high temp limit switches and for continuity in the wiring, switched with a known working ignition control board, as well as a working main control board with no success. Seems really odd when known working main board and ign control boards do not work in this unit while all other test functions work in the auto cycle, the unit worked exactly the same before and after swapping the boards. The venter motor works fine when voltage is applied. Am wondering if it may have anything to do with the Lon talk board interfering... But I would think for the auto cycle test it shouldn't. The Lon board appears ok by the way the lights are blinking although I haven't tested it beyond that.

Flaking Pain On Metal Window Frame

I am renovating my basement and noticed the 2 window frames have a metal bottom frame that have metal flaking off. My idea to resolve the issue is to use a small hand sander to remove the flaking paint and simply use a paint brush to put a new layer of paint. I have a few questions:



1) Why would metal be used?

2) Why is it flaking? I don't notice any moisture nor do I see any damage to the sheet rock

3) Can basic interior paint be used (e.g. ceiling / flat paint)?

How to Add and Manage Multiple Accounts on Instagram

Instagram has now released one of its most requested features.

The ever-popular photo sharing app announced that following the release of version 7.15 for iOS and Android users will have the ability to switch between multiple accounts.

This news is sure to make power users and social media managers jump with joy as managing multiple accounts for brands (or your pets) has been a time-consuming task up until now.

Here's a super-quick guide on how to add and manage multiple accounts on Instagram.

Adding and switching between multiple accounts

Once the feature is live (it's being rolled out to all users gradually this week), you can manage up to 5 Instagram accounts without having to login and out to switch between each account.

To add an account, head over to your profile page, click the settings cog in the top right corner and look for the 'Add Account' option:

From here you'll be taken to a login screen to connect another account. Once you have multiple accounts connected, you can switch between them by tapping on your username at the top of your profile screen and then tapping on the account you'd like to manage:

You can also switch between accounts by holding over the profile icon in the bottom right of the screen from anywhere within the Instagram app:

Once you hold down the profile image, you'll then see a list of your connected accounts, and from here you can choose which account you'd like to manage:

Instagram will show the profile photo of the account you're managing throughout the app to make it easier to see which account you're active on at all times.

How to remove an account

To remove an account, first switch to the profile you'd like to remove and head over to your account settings and tap Log out of [username]:

Bonus: A new way to engage with images

This update also brings with it a great new way to like and comment on images as well as share their them via DM.

When you're looking at a post in the grid view (on someone's profile or search results), you can tap and hold to expand the image and also like, comment and share:

Over to you

Do you manage multiple Instagram accounts? If so, I'd love to hear from you in the comments. How much time will this update save you? How had you been managing all your accounts previously?
