HCA Use a heating curve to calculate discharge
air temperature setpoint from the room
temperature setpoint and outdoor air
temperature.
H,X Calculate enthalpy and absolute humidity.
MAT Mathematical editor to modify inputs to
other control icons.
MAX Select the highest value among analog
inputs (2 through 6).
MIN Select the lowest value among analog
inputs (2 through 6).
NIPU Use cold outdoor air during non-working
(nighttime) hours to precondition room
space and save energy costs.
EOH Calculate optimized values for starting and
stopping heating system.
EOH3 Calculate optimized values for starting and
stopping the heating plant and for the
supply water setpoint.
EOV Calculate optimized values for starting and
stopping air conditioning plants.
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 Same as previously defined PID with the
addition of an integration time parameter.
RAMP Limit the variation in room temperature
over time ("ramp" function).
RIA Read an attribute of a user address.
SEQ Sequence from one to three analog
outputs dependent on an analog input.
DIF Determine the difference between multiple
analog input values
(2 to 6; X1 - (X2 + X3 + ... X6)).
WIA Write to an attribute of a user address.
ZEB Determine setpoints to maintain a
predetermined comfort band divided into
heating, cooling, and zero energy bands.
