WEBVISION™ Purpose The control portion of the loop is an Enhanced PID (EPID) algorithm. The user configures control algorithm type (PID or Non-linear), bias (position of set point within the proportional band (i.e. 0% or 50%), direct/reverse acting output, which sensor and outputs to use, throttling range, integral time, derivative time, start up ramp time, recovery, reset and sequencer parameters, set points, minimum on, off and bypass times, DLC shed bump and lead/lag.
WEBVISION™ • Setpoint Override: A configured setpoint overrides the existing setpoint if the corresponding Digital Input is TRUE. The Digital Input1 maps to Setpoint1, Digital Input2 maps to Setpoint2, vice versa. b. Loop Configuration • Reset: Control loops allow the setpoint (only in occupied mode) to reset either in the direction of increased energy savings or in the direction of the increased comfort. The reset of a control loop is dependent on the analog reset sensor input.
WEBVISION™ Purpose • On Delay Time: The delay in time for switching from one state to another before the output value switches to ON. • Off Delay Time: The delay in time for switching from one state to another before the output value switches to OFF. • DCAO: Digital Compare Analog Output - Sets the output value to equal analog input_1 if digital input is true and analog input_2 if the digital input is false. DCAO must be configured if the Logic Loop analog output is to be used.
