Accurate, responsive microprocessor control
Vapor-logic

provides exceptional functionality, ease of use, and
accurate RH control. Standard on all Vapormist models, this
controller features:
• Real-time clock allows time-stamped alarm tracking and three
ways to program drain and flush cycles:
1. Usage (unit drains after a set number of pounds of water have
cycled through)
2. Usage and time (unit drains at a preset time after a set number
of pounds of water have cycled through)
3. At a preset time
• Keypad has a backlit display and features:
– Intuitive menu-driven access to all system functions
– Default screen for quick viewing of system status and set points
– Data reports to track performance and efficiency
– System diagnostics and alarm tracking for troubleshooting
– Password protection of setup parameters
– Easy viewing in low-light environments
– Three ways to mount the keypad:
1. Mounted on the Vapormist cabinet
2. Hand-held; shipped with a 5' (1.5 m) cable
3. Mounted remotely using a standard telephone plate. The
keypad can be located up to 500' (152 m; the maximum
length of the keypad cable) from the Vapormist.
• Tank temperature sensor, mounted on the evaporating chamber,
allows Vapor-logic
3
to provide:
– Over-temperature protection
– Freeze protection
– Tank preheating, allowing rapid response to a call for humidity
• PID control provides accurate, responsive, and adjustable relative
humidity (RH) control.
• LonTalk interoperability allows communication with a LonTalk
building automation system using Standard Network Variable
Types (SNVTs). Note that LonTalk interoperability with a
building automation system is not available when using multiple
humidifier control.
• Multiple-humidifier control allows control of up to 16
humidifiers with one controller. The primary benefit of
multiple-humidifier control is expanded capacity without giving
up consistent humidity control. The Vapor-logic
3
controller
anticipates increased demand and preheats tanks as needed to
provide a rapid response to demand changes.
The Vapor-logic
3
keypad is easy to use and
read, and it provides access to all humidifier
functions.
