Mixing Operation (European Version)
Terminal Units
When using a Characterized Heating Curve, the control requires the selection of a terminal unit. The terminal unit determines the shape of the
Characterized Heating Curve according to how the terminal unit delivers heat into the building space. The Stk# 31360 provides for selection
between six different terminal unit types: two types of radiant floor heat, fancoil, fin-tube convector, radiator and baseboard. When a terminal unit
is selected, the control automatically loads the design supply temperature (MIX DSGN), maximum supply temperature (MIX MAX) and minimum
supply temperature (MIX MIN). The factory defaults are listed below. To change defaults, refer to Advanced Mixing Pg. 10; If a default has been
changed, refer to Pg. 5 to reload the factory defaults.
High Mass Radiant (1)
This type of a hydronic radiant floor is embedded in either a thick concrete or gypsum pour. This heating
system has a large thermal mass and is slow acting.
Default values: MIX DSGN = 120 °F (49°C), MIX MAX = 140 °F (60°C), MIX MIN = OFF
Low Mass Radiant (2)
This type of radiant heating system is either attached to the bottom of a wood sub-floor, suspended in the
joist space, or sandwiched between the sub-floor and the surface. This type of radiant system has a relatively
low thermal mass and responds faster than a high mass system.
Default values: MIX DSGN = 140 °F (60°C), MIX MAX = 160 °F (71°C), MIX MIN = OFF
Fancoil (3)
A fancoil terminal unit or air handling unit (AHU) consists of a hydronic heating coil and either a fan or
blower. Air is forced across the coil at a constant velocity by the fan or either a fan or blower. Air is forced
across the coil at a constant velocity by the fan or blower, and is then delivered into the building space.
Default values: MIX DSGN = 190°F (88 °C), MIX MAX = 210°F (99°C), MIX MIN = 100°F (38°C)
Fin–tube Convector (4)
A convector terminal unit is made up of a heating element with fins on it. This type of terminal unit relies
on the natural convection of air across the heating element to deliver heated air into the space. The amount
of natural convection to the space is dependant on the supply water temperature to the heating element and
the room air temperature.
Default values: MIX DSGN = 180 °F (82°C), MIX MAX = 200 °F (93°C), MIX MIN = OFF

Setpoint Operation (MIX TARGET)
For setpoint control, 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.
Room OCC & UNOCC (ROOM)
The ROOM is the desired room temperature for the mixing zones, and it provides a parallel shift
of the Characterized Heating Curve. The room temperature desired by the occupants is often
different from the design indoor temperature (MIX INDR). If the room temperature is not correct,
adjusting the ROOM setting increases or decreases the amount of heat available to the building.
A ROOM setting is available for both the occupied (Day) and unoccupied (Night) modes.
