Description
Differential
Controller
Calculates the derivative output signal, which
changes in proportion to changes of the input
signal. Y = 0 if the input is unchanged since
the last cycle. Y > 0 if the deviation is
increasing. Y < 0 if the deviation is
decreasing.
Division
Arithmetic
Divides input A by input B.
Duty Cycle
Duty cycling
Energy management
Switches HVAC systems alternating on and
off to save energy.
ECO
Economy
Legacy XL500
Legacy RACL function: Decide on the most
economical system operation for full and
partial air conditioning systems.
Economy
Energy management
Decide on the most economical system
operation for full and partial air conditioning
systems.
Enthalpy
Enthalpy
Misc
Calculate enthalpy (Ent) and absolute
humidity (HAbs) as a function of air
temperature, relative air humidity, and air
pressure. Use Enthalpy with the Economy
function.
EOH
Optimized heating
Energy management
Calculate optimized values for starting and
stopping the heating plant and for the supply
water setpoint.
EOH3
Optimized Start/Stop
Energy management
Calculate optimized values for starting and
stopping the heating plant and for the supply
water setpoint.
EOV
Optimized ventilation
Energy management
Calculate optimized values for starting and
stopping air conditioning systems. Systems
should start at the latest possible time and
should stop as soon as possible to save
energy.
EQL
EQL
Legacy XL500
Legacy RACL function: Compares "Comp"
input with all other inputs. If at least one input
is equal to the "Comp" input, the output is set
to TRUE (1).
Exponential
Arithmetic
Calculates the exponential.
Factorial
Arithmetic
Calculates the factorial (5! = 1*2*3*4*5).
HC
HC
Legacy XL500
Legacy RACL function: Calculates an output
according to a user-defined heating
compensation curve.
HCA
Heating curve
Energy management
Calculates an output according to a user-
defined and adaptable heating compensation
curve.
Hysteresis
Digital Switch (2PT)
Controller
On/off controller that generates a digital
output depending on the deviation of the
controlled variable from the reference
variable. Y1 = 1 if X >= W, Y1 = 0 if X < W –
Hysteresis. Y2 = 1 if X <= W, Y2 = 0 if X > W
+ Hysteresis.
