proliphix thermostat with Trane RTU 25 tons

[atamai]

hello everyone, im new on this forum and i hope you can help me.

I purshase 6 thermostats NT120e and install on single stage RTU 7.5 Tons wit no problems, we develop a centralized software to get communication with this 6 units, everything seem to be working fine!!

But i have 16 RTU 25 Tons Trane Voyager series with ReliaTel Refrigeration Module (RTRM) connections.

I try to put one NT120 on the thermostat bus and works, i can turn on and turn off but i don't know if this NT120 will manage dual stage correctly on the RTU or some other intelligent feature.

On past i had a simple Trane analogical thermostat wired to the RTU, and works, but i want to know if some one have any issue on this kind of RTU.

Thanks!!

I've never installed a Proliphix thermostat but just looked at the installation instructions. Shouldn't be any problem, it can be used as a two stage heat, two stage cool thermostat. It gets connected to the Conventional Thermostat terminals on the unit, not the same terminals the Trane sensor used.
