Wiring a multi-tank group of humidifiers
This section describes making wiring connections for multi-tank
systems. To wire a multi-tank group of humidifiers:
1. Determine which control board is the master controller. The
master controller ships connected to the keypad/display. The
master controller is labeled as Tank A on the keypad/display.
2. Connect all required control inputs to the master controller
board by following the instructions in the installation wiring
section of this manual.
3. Wire all control boards of the multi-tank group together
using twisted pair wire. Connect controller boards together at
terminal block P8. Connect positive to positive terminals, and
negative to negative terminals. On the last board in the series of
connected boards, change the switch labeled “SW1” (located on
the Vapor-logic4 board next to P8) to the On position.
4. Connect the keypad/display and/or Web interface cable to any
control board in the multi-tank system.
