Algorithm: A series of computer software equations which instruct decisions to be made and calculation to be

performed.

Alphanumeric: Pertaining to a character set that contains both letters and numbers and usually other characters.

Cable (Plenum Rated): A plenum or duct rated interconnecting electrical cable with twisted pairs of wires,

including shielding and grounding wire. Cable used to reduce electrical interference into sensitive electronic

components.

Cold Snap: See Temperature Transmitter.

Connector Shunt: A small plastic connector used to select type of control input on VAPOR-LOGIC

P.C. board.

Control Span: An output signal range where proportional action takes place. 6-9 VDC range typical for

DRI-STEEM. An input signal range by others where proportional action takes place.

(6-9 VDC range, 17-117 ohm range or 5-19 mA range typical for DRI-STEEM.)

Cycle Time: The time necessary (seconds) to complete a full on - through - off period in a time proportioning

control system with contactors on solid state SCR power controller.

Delay Time: Time in seconds to energize or de-energize additional output stages.

Derivative: The control action to compensate for the rate or anticipatory change of the % RH.

Droop: A term used with proportioning controls. Refers to the difference between % RH (set point) and actual %

RH values once the system stabilizes.

Digital Display: An alphanumeric Digital Display / Key Pad assembly allows user to review and change the

control parameters.

EEPROM: Electronically Erasable Programmable Read Only Memory chip.

Error: The difference between the desired % RH (set point) and the actual % RH value reading.

Fault Relay: A SPDT relay mounted on VAPOR-LOGIC printed circuit board, energized when a fault condition is

detected.

Firmware: Software programs and instructions that are stored in memory type IC chips.

Heartbeat/ Fault Indicator: An indicator lamp mounted on VAPOR-LOGIC printed circuit board to give visual

information of system operating status.

High Limit Humidistat: A controlling humidistat that is mounted in a duct to prevent a high humidity level.

Humidistat: A controlling device that regulates and maintains a degree of humidity in % RH.

Humidity Transmitter: A monitoring device that senses the humidity level and provides an output signal based

on humidity level.

Integral: The control action that allows the proportional controller to adjust the % RH to the desired set point after

the system has stabilized to eliminate droop.

Local Digital Display: Digital display / key pad identified as “LOCAL” module to VAPOR-LOGIC, no connector

shunt on J6.

Main Menu: The main list of items to review or change the control parameters.

Microprocessor: The control and processing portion of VAPOR-LOGIC that handles arithmetic and logic.
