Icon Name
Description
Heating Curve with
Adaptation
HCA
Use a heating curve to calculate discharge
air temperature setpoint from the room
temperature setpoint and outdoor air
temperature.
Humidity and Enthalpy
H,X
Calculate enthalpy and absolute humidity.
Mathematical Editor
MAT
Mathematical editor to modify inputs to
other control icons.
Maximum
MAX
Select the highest value among analog
inputs (2 through 6).
Minimum
MIN
Select the lowest value among analog
inputs (2 through 6).
Night Purge
NIPU
Use cold outdoor air during non-working
(nighttime) hours to precondition room
space and save energy costs.
Optimum Start/Stop
EOH
Calculate optimized values for starting and
stopping heating system.
Optimum Start/Stop
EOH3
EOH3
Calculate optimized values for starting and
stopping the heating plant and for the
supply water setpoint.
Optimum Start/Stop
Energy Optimized
Ventilation
EOV
Calculate optimized values for starting and
stopping air conditioning plants.
PID
PID
Proportional-Integral-Derivative controller
that regulates an analog output based on
two analog values (one is a controlled
variable; the other, a reference variable.)
PID (with integration time
parameter)
PID
Same as previously defined PID with the
addition of an integration time parameter.
Ratio
RAMP
Limit the variation in room temperature
over time (“ramp” function).
Read
RIA
Read an attribute of a user address.
Sequence
SEQ
Sequence from one to three analog
outputs dependent on an analog input.
Subtract
DIF
Determine the difference between multiple
analog input values
(2 to 6; X1 - (X2 + X3 + ... X6)).
Write
WIA
Write to an attribute of a user address.
Zero Energy Band
ZEB
Determine setpoints to maintain a
predetermined comfort band divided into
heating, cooling, and zero energy bands.
EOH3
