Will Waltech Vision 2.0 Work With 2025 Keystone Montana With 3 AC Units

Updated 02/12/2026 | Published 02/07/2026

Question:

I have a question about Waltech Vision 2.0 RV Thermostat and Wireless Control Hub - Bluetooth Part Number: WA74FR. I have a 2025 Keystone Montana with 3 A/Cs, one of which has a heat pump. They each have their own wall controller. How would the Waltech Vision 2.0 work with a system like this? Do I need to have 3 of these, one to replace each existing A/C thermostat or are there smaller “relay” units that would relay data and commands to a main unit?

Hi Scott; what AC system do you have on your 2025 Keystone Montana? Do you know if this is an R32 system or the older R410A? I will need that information to run it by Waltech. This can handle multizone setups but certain AC systems aren't going to work depending on how they're wired.

I have 2 Coleman-Mach A/Cs, Series 38200 (specifically model 38209-0650) and 1 Coleman-Mach A/C with Heat Pump, Series 38000 (specifically model 38009-0650). I looked through the owners manual, but did not see anything regarding refrigerant type.

@ScottH it looks like those are R32 units so they won't be compatible with the Waltech. Initially we were told the thermostat was R32 compatible but they have since revised what they said. Until they update the thermostat it can't be used with R32.
