Vapor-logic4 controller

Accurate, responsive control

The Vapor-logic4 controller provides accurate, responsive RH

control. PID control tunes the system for maximum performance.

Modbus, BACnet MS/TP, or LonTalk allow interoperability with

multiple building automation systems. Modbus is standard, and

BACnet MS/TP or LonTalk are available options.

Web interface provides the capability to set up, view, and adjust

humidifier functions via Ethernet, either directly or remotely

through a network.

Cycle counter triggers a message when it’s time to replace the

contactor.

USB port allows easy firmware updates, and data backup and

restore capability.

Real-time clock allows time-stamped alarm and message tracking,

and accurate drain and flush scheduling.

Auxiliary temperature sensor/transmitter allows air temperature

monitoring, such as in a duct, and enables temperature

compensation to prevent window condensation.

Programmable outputs allow remote signaling and device

activation.

Multiple-humidifier control allows staged control of up to 16

humidifiers with one controller.

Controller data, such as RH, air temperature, water use, energy

use, alarms, and messages, can be downloaded to a PC for viewing

and analysis. RH, alarms, and messages can also be viewed on the

keypad/display and Web interface.

Enhanced diagnostics include:

• Test outputs function using keypad/display or Web interface to

verify component operation

• Test humidifier function using simulated demand to validate

performance
