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.
ROOM TEMPERATURE – OCCUPIED (ROOM OCC)
(See fig. a)
This is the desired room temperature the occupant is using
for the mixing zone when the room is occupied. This setting is
used in the reset ratio. The default setting for this screen is 70°F.
ROOM TEMPERATURE – UNOCCUPIED
(ROOM UNOCC)
This is the desired room temperature the occupant is using for
the mixing zone when the room is unoccupied. This setting is
used in the reset ratio. The default setting for this screen is 65°F.
OUTDOOR DESIGN TEMPERATURE
(OUTDR DSGN)
(See fig. b)
OUT DSGN is the outdoor design air temperature based on a
percentage of the average coldest temperature where the
building is located. This is the temperature used when
performing heat-loss calculations for the building.
MIXING INDOOR TEMPERATURE (MIX INDR)
(See fig. c)
MIX INDR is the room temperature used in original heat-loss
calculations for the building. This setting establishes the
beginning of the reset ratio for the mixing zone.
MIXING SUPPLY DESIGN TEMPERATURE
(MIX DSGN)
(See fig. d)
MIX DSGN temperature is the design supply water
temperature required to heat the mixing zones when the
outdoor temperature is at OUT DSGN temperature. This
information is obtained from the project’s heat-loss/design
information.
