CT50 installation difficulties

I’m setting a new VeraPlus controller. It’s been a learning curve but I’m getting there. Trying to set up a Radiothermostat on Zwave and having issues. It shows two thermostats with different temperature state off by .5 degrees F. I can turn it on and off remotely but it won’t hold my temperature setting. It keeps going back to another program even though I have reset everything to a fixed temperature of 35 degrees. It’s in my garage workshop so I keep the temp low when not in use. I’ll set it then come back later and it’s on 70 degrees. I’m pulling my hair out.
