Floor Heat with Silverleaf

I have an issue that cropped up where my "front" floor heat is not working. I first noticed that the little squiggly lines on my silverleaf display never lit up red as being "on" like the other two zones (see photo), and of course the floor wasn't heating in the front zone either.
So I checked breakers and GFIs, all were on, nothing tripped. So I found the junction box labeled "living room" which is the front zone and started checking connections. I have 128v at the relay terminals (com to NO) which means all I need is for that relay to close to turn that zone on. The problem is I don't have 12v to "coil" section of the relay, no matter where I set the zone setting. I did a reset of the 12v system, but no change. I found the TM-229 module, unplugged, checked and replugged all those connections, no change.
Is there something else to check, or a way to check the Silverleaf system for this issue?
(not sure why this turns my photos sideways, apologies)

There is not much you can do except check wiring. There is a data port to connect a computer but you have to have the software to do anything.

I did have the opposite problem. I keep the coach in my garage and a couple of weeks ago I walked into it and it was 110° inside and the living room and bedroom floor he was on. The Silverleaf showed nothing on so I threw the breakers and then called Silverleaf.

They had me turn the breakers back on and as soon as I did you could hear the relays energize and both areas started heating up. They had me unplug the SL floor heat module, the TM 250 main module in the power bay and also unplug the display. They couldn’t explain it but it fixed it and I haven’t had a problem since.

Silverleaf is very helpful, I would give them a call on Monday. That is, unless you are like me and this happened on a weekend where I could not call Silverleaf. Then I would have torn half the coach apart trying to figure it out. LOL

I had same problem in my 16 MADP, called silver leaf, said they had problems with control board in basement. Sent me an upgraded board, fixed issue, give them a call. Good luck! NO CHARGE, I like that!

Called Silverleaf this morning, they had me check a few things and determined that my TM-250 module was causing the issue. I have a new one on order which should correct the issue and I should have plenty of floor heat by the time the weather warms up here!!

P.S. The guys at Silverleaf are the best to work with!!

Pat,
While you were talking to the Silverleaf folks, did they mention the flyback diode on the charge bridge solenoid. It affects the White Rogers solenoids and from what I read can play havoc on Silverleaf modules.

They did not mention that on this call, but have before. I couldn't find any numbers on my solenoid to tell if it was a White Rogers or not. Any help on that would be appreciated!

I cannot help with the Silverleaf, but with your last comment I may. From the forum gurus:

Forum and Classified software will display photos in the original orientation in which they were taken. If a photo was taken in landscape (sideways) mode, it will display sideways in a post or ad, even if you have it stored in portrait (upright) mode on your device. Use a photo editing or snipping tool to save a copy of the photo in portrait (upright) orientation and upload that copy (not the original) in your post/ad.

I talked with Silverleaf and sent them a photo of my solenoid (see photos, sorry if they're sideways), and promptly heard back from them that mine is a "Blue Sea, 250-Amp model" and does not require a diode! Nice, finally get a break!!
