P.I.D.: Proportional, Integral, Derivative. A control mode with three functions. Proportional action dampens

system response, integral corrects for droop, derivative seeks to prevent overshoot and undershoot.

Pneumatic-Electric Switch: Pneumatic/Electric off-on switch, pneumatic input range .2-1.4 bar, preset pneu-

matic setting for electrical switch closure.

Prompt: An alphanumeric instruction displayed on the digital read-out directing you to perform an action to

proceed with the VAPOR-LOGIC

software.

Proportional Band: The range in which the VAPOR-LOGIC system controls the proportioning function, ex-

pressed in percent of RH span.

Rate: See Derivative.

Reset: See Integral.

Remote Digital Display: Digital display / key pad identified as “REMOTE” module to VAPOR-LOGIC board and

digital display / key pad.

Sample Interval: The specified time in seconds that the input/output values are sampled to evaluate and adjust

the control function of P.I.D. control terms.

SCR Power Controller: A power regulating device that controls voltages and current to the heaters and in-

cludes a command signal board.

Scrolling: When VAPOR-LOGIC is in “Auto” mode, the digital module continually moves information across the

digital display screen.

Software: The entire set of programs, procedures and related documentation associated with VAPOR-LOGIC

system.

Sub-Menu: The point in the main menu where the parameters are reviewed and changed.

Temperature Transmitter: A monitoring device that senses the window glass temperature and provides an

output signal based on the temperature level.

Range: -29° to 49°C part no. 405882 (model T184) used with firmware V1.01 through V1.10.

Range: -29° to 71°C part no. 405889 (model T184-H) used with firmware V2.01 and higher.

Throttling Range: The span in % RH symmetrically around set point using digital display module and humidity

transmitter or the control signal span from a humidistat where VAPOR-LOGIC time proportioning control action

takes place.

VAV: Variable Air Volume system notation.
