Mix Minimum (MIX MIN)
The MIX MIN is the lowest temperature that the control is allowed to use as a MIX TARGET temperature. During mild conditions, if the Stk#
31360 calculates a MIX TARGET temperature that is below the MIX MIN setting, the MIX TARGET temperature is adjusted to match the MIX
MIN setting. During this condition, the MIN segment will be displayed in the LCD when either the MIX TARGET or MIX temperature is being
viewed.
Mix Target Temperature (MIX TARGET)
When used as a mixing reset control, the MIX TARGET temperature is calculated from the
Reset Ratio settings and the outdoor air temperature. When used as a setpoint control, the
installer sets the MIX TARGET temperature. The control displays the temperature that it
is currently trying to maintain as the mix supply temperature. If the control does not have
a mix demand, “- - -” is displayed as the MIX TARGET in the VIEW menu.
Setpoint Operation (MIX TARGET)
For setpoint operation, set the OUTDR DSGN to OFF. The MIX TARGET becomes the setpoint supply temperature that the control is to maintain.
The MIX TARGET temperature is set by the installer in the ADJUST menu. An outdoor sensor is not required during this mode of operation.
