Problem with new appliance transmitting So Upset!

I check out everything before I buy. No exception w/ my off grid heat stove. No electric required, so the company said, but then they redesigned the unit right before I placed the order.

Going into the second month and heat still not installed. First it was put on hold as the heater now requires AC and I only have DC low emf solar. Put on hold for some time while my installer found a work around to make it work $$$.

Then my installer informs me that I must pay so much for a basic thermostat. I had paid $30 for one to be sent when I ordered the heater stove. None was sent, but instead they sent their fancy pricy remote.  At first glance it looked great. TV remotes are of no problem to me. But feeling leery and not trusting it, I researched into and found the remote is one fat RF transmitter! It transmits to the heater and constantly tells it what to do.  I have told the installer I can not have it and would pay for the basic thermostat and I would call to return the horrid remote. This is all upsetting.

I am very worried now that the heater itself may have something that transmits, as well.  From the literature it looks like it's just the remote and the heater just receives. I have not initiated my move yet nor is the stove install done yet so now is the time to do something if it does.  I medically require heat and that is the reason I purchased the lousy unit to begin with, as I need it up even if the solar goes down or dead batteries and the like.

Would like you feed back on if you think that my heater is going to transmit-here is the link:

Could use some moral support as well.
