Myt8411r1028 Thermostat Will Not Reach The Desired Setpoint What Do I Do?

This is really during cold months where heat is needed the most. So I do not typically use it in summer months. The thermostat is paired with a gas furnace description Trane XL80,model number TUD080R936K5, serial number number 4315RU51G, if any of that helps. Now the thing is we have got it to hit the desired set point sometimes or days will pass and then it will reach its setpoint but I want to know how to get it to the setpoint all the time.

Manual temperature change When the Backup Heat Differential is set to Comfort, the thermostat uses backup heat as needed to keep the indoor temperature within 1° F (0.5° C) of the setpoint. When the Backup Heat Differential is set to 2° F or higher, if the primary heat is making progress as expected, backup heat will not be used to reach the new setpoint. Set to a higher number to use less backup heat (a greater difference between the current indoor temperature and the new setpoint is required to turn on backup heat).

During a programmed recovery (or when the temperature setpoint is changed by the user), the thermostat waits to turn on the backup heat depending on system performance, load conditions and how many degrees the temperature setpoint is changed. Backup heat will be used ONLY when the temperature is not rising quickly enough to reach the setpoint in a reasonable time.

If the backup heat was used in the last 2 hours because the primary heat was not able to maintain the setpoint, the thermostat may turn on the backup heat earlier when the user raises the setpoint. This does NOT apply to heat pumps with fossil fuel backup heat.
