Lowest heat setback temp on various TSTATS?

I have two Trane TZEMT500AB32MAA TSATS at home running on Schalge LiNK at the moment and would like to use one at another home in Truckee, but speaking with customer support to confirm lowest setback point is only 50 degrees f. I’d like to have a setback at 40 or 45 degrees.

Does anyone know if the other z-wave compatible TSATS can go to a lower heater setpoint? Thanks.

I have the 2Gig Tstat (made my Radiothermostat) and don’t have such a limitation, I think I’ve set it at 40F
