Summary of features
VAPOR-LOGIC®
3 features overview.
Accurate, responsive
microprocessor control
Our newest controller, VAPOR-LOGIC3,
provides unprecedented, comprehensive control for
RI-STEEM humidifiers. With expanded capabilities,
easy-to-use keypad, and modular, open protocol design,
the VAPOR-LOGIC3 efficiently controls all humidifier
functions.
Navigating the keypad to adjust or review humidifier
functions is an intuitive process of walking through
easily-read screen menus. The controllers open-
protocol design allows seamless integration with
building management systems.
You will find no other controller in the humidifier
market able to provide such functionality, ease of use,
and accurate RH control.
Control mode options
On-off operating mode controls single or
multiple electric staged outputs.
Expected accuracies: ±5-7% RH
Time proportioning function controls humidifier
outputs via cyclic actions on electrical contactors
or a modulated signal to our solid state zero cross-
fired SSR power controllers.
Expected accuracies:
Contactor action: ±2-4% RH
SSR action: ±1-3% RH
Proportional action controls modulating steam or
hot water valves or GTS burners by providing a
linear analog signal to the motors (for STS, LTS or
GTS humidifiers).
Expected accuracies: ±2-5% RH

Summary of features
PID control provides the most accurate,
responsive and adjustable relative humidity (RH)
control.
Self-diagnostic test at start-up
End of season auto-drain
Real-time clock allows time-stamped alarm
tracking, and three ways to program drain and
flush cycles:
1. Usage (after a set number of kg have cycled
through)
2. Usage and time (set number of kg plus defined
period of time)
3. Scheduled intervals
Redesigned keypad has an intuitive interface with
backlit display and provides:
menu-driven access to all system functions
default screen for quick view of system status
and set points
data reports to track performance and efficiency
system diagnostics and alarm tracking for
troubleshooting
single-point multiple-humidifier control without
an additional system controller
password protection of setup parameters
wall-mounting with a standard telephone plate,
flush mounting, or hand-held options
Tank temperature sensor
preheats tanks for uninterrupted operation
senses for freeze protection
senses for low water/over temperature protection
Sensitivity to low-conductivity water (important
when using a standard humidification system with
low-mineral-content water)
Uses Echelons LonTalk®
, an open
communications protocol used by most major
control companies, allowing full interaction with
building management systems
Single-controller platform; modular design
The new VAPOR-LOGIC3 controller will soon be
standard on all RI-STEEM humidifiers. The base
configuration includes a main controller board and
keypad. Expansion modules will increase
capability, thereby allowing all systems to use the
same controller platform and keypad interface.

ouble terminal T1 24 VAC, 10 VA maximum
load
Triple terminal T2 24 VAC common
J2 RJ11 female modular jack connection for supply
voltage and FTT-10A communication to keypad/
display
J3 RJ45 female modular jack connection for FTT-
10A communication to LonTalk® network
J4 Wire terminal connection for FTT-10A
communication to LonTalk network. Terminals A
and B provide the communication lines. The last
terminal is earth ground.
J5 End of line communication terminator pins
J6 Push-on connector for earth ground
J7 0-15 V C analog output, typically connected to
the input of a steam or hot water valve. Terminal
34 is the positive output signal and terminal 35 is
common.
J8 Connector receives necessary continuity input
signals from water detection devices:
Probe system water level detection
Terminal 30 detects maximum water level
from top probe rod and brown plug wire.
Terminal 31 detects water level at refill point
from middle probe rod and orange plug wire.
Terminal 32 detects water level at its lowest
point from lower probe rod and purple plug
wire.
Terminal 33 is the common return path for all
water detection rods from the humidifier tank
machine ground back to
VAPOR-LOGIC3 control.
I/RO system detection
Terminals 30 and 31 are not used.
Terminal 32 is connected to the humidifier
tank low water float switch (normally open).
Terminal 33 is the return signal from the float
switch to VAPOR-LOGIC3 control via
machine ground.

Important note about J17, J18 and J19:
All connection diagrams show connector shunts
on J17, J18 and J19. The connector shunts and
appropriate software have been selected by
RI-STEEM based on original customer orders.
Field changing the input connector shunts will
require control input modification See Page
23 Changing Control Input.
J17 Jumper pins determine the configuration of the
type of input control into the RH sensor input
(terminals 21 through 23) for wire terminal
connector J26.
