Need Carrier VVT Control System gen.2 master controller

[Rudemom]

We need working Carrier VVT Control System Generation 2 master controller. Ours have taken a dump and do not want to shell out $34k for a new system. Anyone know of where we might locate a few?

[AirTechMech]

Hmmm, I just very well may have one in stock. Give me a day to check my inventory and I will post back here.

[Rudemom]

Outstanding! I just verified the part number. It needs to be either an MST01ES or MS01ES

[AirTechMech]

I didn't verify I have it yet, sorry for the delay I will try to get into that trailer today.

By the way that is second generation enhanced.

[Rudemom]

Okay. Do you know if the master contoller can be repaired when it fails and is 20 years old? Is it possible??

I have a gen3 monitor stat without time clock . It should be backwards compatible to a gen2 monitor stat.

let me know if interested.

You sure about that? GenII uses the rotary switch forprogramming while Gen III uses the push buttons (4 of them)

It is not backward compatible, sorry

Also I do not have the Parker VVT Gen2E monitor stat, if I do I can not locate it. As for repairing them I am not aware of anyone doing this.

Did you ever get a new stat?

[Rudemom]

Nope - had to buy a whole new system.

Go to Ebay Business & Industrial, subset Industrial Supply & MRO, subset HVAC, and search block Carrier MS*. Saw 2 items starting with MS.
