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.
