Set points
Set points are used as the cut in/ out for various i-
controller functions. The i-Controller Set Point
configuration section has 3 navigation screens.
The “Set Points” option should only be used if operation
set points
are not
being communicated to the
Flō
i-
Controller from a Building Management System (BMS).
If the
Flō
i-Controller is connected to a BMS over Modbus,
the set points shown on this screen will be automatically
updated with the set points entered in the BMS. The VAV
Set Points will only appear if VAV controls are connected
to the
Flō
unit. The set points limitations are as follows:
Cool SP: 60 - 85F
Heat SP: 50-80F
Dew Point SP: 48-60F
There must be a minimum of 4-degrees between the
heating and cooling set points. If set points are inputted
too close together, the program will automatically adjust
the set points per the following rules:
Outdoor Air Temp > 60 ˚F: Heating Set Point = Coo
ling Set
Point -
4 ˚F
Outdoor Air Temp < 50 ˚F: Cooling Set Point = Heating Set
Point + 4 ˚F
