    This function is used to reset the existing reset ratio based on lower room heat demands during unoccupied versus occupied time periods. The proMIX 101 does not actively use this function. To be truly effective, this function should be incorporated with a master setback thermostat with the ability to slave all other thermostats to the setback activity.

  • Page 39: Section B – Mixing Zones

    CONTROL FUNCTION OVERVIEW - SECTION B MIXING ZONE The proMIX 101 can provide a reset or setpoint supply water temperature from the primary boiler loop to a secondary mixed loop via a floating action 3-way valve. The following section provides information on screen function activities for the control.
  • Page 40 MIXING SUPPLY TARGET TEMPERATURE – RESET MODE (MIX TARGET) (See fig. e) MIX TRG temperature is determined from the reset ratio settings established from the input settings in the ADJUST Menu. With a heat demand, the control displays the temperature it is currently trying to maintain as the mixing supply temperature.

  • Page 41: Section B – Mixing Zones

    In this case, when the boiler is firing and the boiler return water temperature is below the BOIL MIN setting, the proMIX 101 turns on the BOIL MIN segment in the LCD. The control will then reduce the heating load on the boiler by limiting the output of the floating action 3-way valve.
