PROFLAME 2 thermostat needs calibration with actual room temperature

[RJL24]

I own a PROFLAME 2 transmitter- remote for a Joutl gas fireplace. The temperature showing on the remote control is at least 3 degrees HIGHER than three other thermostats sitting next to the PROFLAME 2. The PROFLAME 2 SHOWS 73 DEGREES THE OTHER THERMOSTATS SHOW 70 DEGREES.
Is there a way to calibrate the temperature on this PROFLAME transmitter?

Following. I have the same problem but mine is off 6 degrees lower.
