VAPOR-LOGIC

®

3 main control board connections

J1 Wire terminal supplies 24 VAC to power the

VAPOR-LOGIC

3

control board.

• Double 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 1/4" push-on connector for earth ground

J7 0-15 VDC 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-LOGIC

control.

• DI/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-LOGIC

3

control via

machine ground.
