HWH/Level Low integration
I’ve been searching for a good diagram that shows how HWH and Level Low are integrated. My simplistic thinking thought that the HWH controller would simply energize the appropriate LL solenoid to exhaust air when needed and/or start the aux-compressor if a raise condition was called for. But there’s a couple MAC electro-pneumatic solenoids that seem to be plumbed in somehow. I don’t get it, that’s why I was hoping to someone had a good diagram.
I know that most of the small compressors tasked with this function won’t actually raise the front if needed, but I’m just looking to understand how it was suppose to work and the physical connectivity.
I’ve been all over the HWH site, even their education pages, can’t find anything that specifically shows a Prevost LL configuration.

Well that didn’t take long, my simple thinking was pretty darn close, but those two mac solenoids aren’t even related to HWH/LL.
Thanks Glenn for the pointer.

Additionally, the HWH will not raise the coach. It just exhausts air to get level. Once you are out of air in your bags it is no longer functional.

Is that by design or due to the undersized aux compressor?

The way my 92 CC is setup, as long as my Level switch is on and I have AUX air, I will maintain level up and down. My bus will hold level for about a week so i don’t bother leaving the switch on. I level and turn it off. There is a post going into depth on this on this site somewhere.
