    This is a temp chiller setup. Two way valve in the AHU, when it closes it trips out the chiller on low flow (of course). This was the solution.

    I'll complain to people about things being hard to get to but this one I brought to the GC. If you look closely you can see the VAV I need to work on behind those pipes that all block a hatch in a hard ceiling.

    On temporary chilled water systems, rental chillers, etc. it's very common to have a manual bypass to balance the flow....especially with rental chillers where the pump packs have way more flow than the system needs.

    It's there, just a bad angle. Big flex that goes around the corner.

    No, this was our panel. Think there was another panel right next to it so the wire was easy to pull. But hey the wire didn't come out of the connector and nothing got damaged.
