  1. My remote was all of a sudden flickering and I assumed it was a battery issue. I replaced the 3 batteries in the remote and the remote works well except for the thermostat function. My fireplace is hard wired. The only way to control the fireplace is with the remote. Your instructions are really not as simplified as I was hoping. Thank you.

    • Hi Sherly

      Usually, weak or dying batteries cause the remote’s sudden flickering. Replacing the battery is an easy solution. But as you are saying you replaced it 3 times but it didn’t work well for the thermostat function. You should contact a technician to inspect the exact problem.


    • Hi Michael

      Did you reset your remote as we told in our guide? If not, first reset and see if it’s working or not. If it still won’t work, then contact a technician.


  2. I have a vogelzang vg5770 pellet stove.
    The thermostat does not seem to control the stove when the stove is running.
    I have selected “thermostat mode” but the stove runs higher (hotter) than my desired temperature input.
    I’ve set the thermostat at 68 and the stove runs continuously … never ramping up or down like I would expect.

  3. After changing my remote batteries, when clicking the temperature button on my remote, it no longer shows the smart option. How do I get the SMART option back?
