Overview

The Vapor-logic4 controller provides comprehensive control for DRI-STEEM GTS, Vaporstream, Vapormist, and Humidi-tech humidifiers.

New features

• Interoperability allows communication with building automation systems via Modbus or with optional BACnet or LonTalk protocols.
• Web interface provides the capability to set up, view, and adjust humidifier functions via Ethernet, either directly or remotely through a network.
• USB port allows easy firmware updates, and data backup and restore capability.
• PID control allows tuning of the system for maximum performance.
• Real-time clock allows time-stamped alarm and message tracking, and accurate drain and flush scheduling.
• Programmable outputs allow remote signaling and device activation.
• Enhanced diagnostics include a test outputs  function to verify component operation, and a  test humidifier function to simulate humidifier  demand to validate performance.
• Auxiliary temperature sensor/transmitter allows air temperature monitoring, such as in a duct, and enables temperature compensation to prevent window condensation.
