CONTROL FUNCTION
OVERVIEW - SECTION A
GENERAL
The proMIX 101 uses a floating action mixing valve to control
the supply water temperature to a hydronic heating system.
The supply water is based on either the current outdoor
temperature or a fixed setpoint temperature. The following
section provides information on general function activities for
the control.
POWERING UP THE CONTROL
When the proMIX 101 is powered up, it displays the
control number in the LCD for 2 seconds. Next it displays the
software version for 2 seconds. Finally, the control enters into
normal operating mode by displaying current outdoor
air temperature.
EXTERNAL MIXING DEMAND
An external mixing demand allows for use of a conventional
thermostat system for zoning. Demand is generated by
applying a voltage between 24 and 240 VAC across the
Mix Demand terminals (1 and 2). Once voltage is applied, the
Mix Demand pointer is displayed in the lower right corner of
the LCD.
• If the proMIX 101 is not in WWSD, it closes the System Pump
(P1) contacts (terminals 5 and 6) and the pump icon is shown
in the control’s display
• The proMIX 101 calculates a MIX TRG temperature based on
outdoor air temperature and other input settings
• When required, the control will close the contacts to the
Boiler Enable (terminals 7 and 8) in order to start the boiler
