Nope...I thought you were just wanting to jump on the N2/RS485. If you want the 9 pin RS232 too, this won't do it.
actually that is one of the ones that a tech uses in my company. may be buying that one. now q? what is the wtrflush value mean in a vav with re heat coil? someone overrided it for some reason.
customer has a simple 100% mua a/h with a steem coil. metasys controller dead. entire plant is pneumatic control. except this pig. guess what i told them when they asked if we can replace it.
It is used for flushing or balancing the HW system. You can command all the valves to go to the selected position with one global command. I've never seen it used.
WATER SYSTEM FLUSH. From The Book This feature is typically used during the startup and commissioning of VMAs on a new job site for the flushing and balancing of building heating water systems. During this mode, the flow rate is modulated to maintain the cooling setpoint. The VAV Box mode present value can be commanded into this mode by setting the Water System Flush parameter (Command modes/Parameters window) equal to True. This feature affects incremental, proportional, and two-position normally open and normally closed box and supplemental heating outputs. This feature is not activated for devices configured with staged electric heat or for box heating AO or DAO outputs if Box Htg Elec Protect is True.

also not sure where to find this info but the metasys has a "*" or "3" next to the cmd * i beleive is user/operator override but what is 3?
I'm not sure about the 3. Do you know what version of Metasys you are using. Companion system, PMI? Sounds like some older stuff. I don't remember off the top of my head what the 3 is.
Hi, don't know if this was answered yet, but the "3" is the priority level of the command. A 3 means an operator override. Regards, J.R.
