2100 Series Maximum Blower Speed - Maximum speed the blower runs during a heat call. Blower speed automatically varies in relation to heating requirements based upon this value and minimum speed (L028). If using a low voltage thermostat and the system is receiving a stage 2 heat call, the blower will operate at this speed. NOTE: Increasing the maximum speed of the fan will result in a higher heat output and increased volume of airflow. In turn the heat stored in the brick core will be depleted sooner, potentially resulting in unsatisfactory performance and noise issues.

3100/4100/4200/5100 Series Maximum Core Blower Speed - This value MUST be set to 255. NOTE: Lowering this value decreases the overall output of the system. Blower speed may be lowered to temporarily reduce a high RPM motor noise until the core blower(s) can be replaced. |

9100 Series Maximum Core Blower Speed - If the core blower wheel is steel (non-aluminum), this value MUST be set to 255. If using an aluminum wheel, this value should be set to 100. NOTE: All systems built after June 1, 2020 are equipped with an aluminum wheel. |
