Changing the Auxiliary Heat Offset Temperature

In heat pump systems, the Auxiliary Heat Offset temperature is the temperature difference at which the auxiliary heat is activated. For single stage systems, it is the difference from the set point; for two stage systems, it is the difference from the second stage offset.

If you desire to change the Auxiliary Heat Offset temperature then use the arrow keys to move the highlight bar to Aux Heat Offset. If you do not have a heat pump system then the Aux Heat Offset feature is not displayed in the options menu list.

Press the key below the OK key label in the smart-key label at the bottom right of the display to select this option. If you decide to cancel the operation then press the key below the Go Back key label in the smart-key label at the bottom left of the display.

After pressing OK, the screen updates to a screen that says Aux Heat Offset at the top of the screen and the current offset temperature in the center of the screen. Use the arrow keys to adjust the temperature up or down to the value you desire.

Press the key below the Set Temp key label in the smart-key label at the bottom right of the display to save your new offset value. If you decide to cancel the operation then press the key below the Cancel key label in the smart-key label at the bottom left of the display.

The initial value is established when the thermostat is initially setup through the MRX Advanced Network System Controller.

Changing the 2nd Stage Offset Temperature

In multi-stage systems, the 2nd Stage Offset temperature is the temperature difference from the set point where the equipment second stage is activated. There is a setting for both heating and cooling. If you do not have a multi-stage system then the 2nd Stage Offset feature is not displayed in the options menu list.

If you desire to change the 2nd Stage Offset temperature then use the arrow keys to move the highlight bar to 2nd Stage Offset.

Press the key below the OK key label in the smart-key label box at the bottom right of the display to select this option. If you decide to cancel the operation then press the key below the Go Back key label in the smart-key label box at the bottom left of the display.

After pressing OK, the screen updates to a new screen where you choose to set either the heating second stage offset or the cooling second stage offset.
