System Installation
6. The Modular Service Tool SD will connect to any
of the controllers using the supplied cable with DIN
connectors on both ends. The connection point on the
controller is located near the communications connector.
The Communications setting must be set to Lo Speed
Network Mode.
7. The System Manager TS II utilizes a 3 wire
communication terminal block for connection to
any controller on the communications local loop that
has communication wire terminals. A separate
transformer is required for the System Manager TS II.
It has a 2 wire 24 VAC terminal block for connection to
a 24 VAC transformer. The transformer should be sized
to provide 6 VA minimum power and should be
connected using 18 gauge minimum wire. In the
Settings Menu, enter <63> for the System Manager
Address.
8. Before powering up the controllers, set each VAV/
Zone Controller’s board address to a unique number
from 1 through 58. Address the VCM-X E-BUS
Controller at 59.
Note: Both power and communications are transferred
from the Power/Comm board to the VAV/Zone
Controllers and the Modular System Manager. Only
communications are transferred from Power/Comm
board to Power/Comm board.
Warning: Each Power/Comm board must have its own
24 VAC transformer for its power source. This
transformer cannot be shared with any other
board. Do not ground the transformer that is
connected to the Power/Comm board. The trans-
former should be sized for the required VA by
using the information found on pages 9-10
of this manual.
Loop Containing VCM-X E-BUS Controller with Non-Modu-
lar VAV/Zone Controllers and CommLink 5 Only
1. Connect 2 conductor shielded cable from the VCM-X
E-BUS Controller’s 3 wire communications connector
to the CommLink 5’s 3 wire communications connector.
Use the 110 VAC/24 VAC power supply furnished with
the CommLink for its power source. Be sure to maintain
polarity on all boards. The Loop switch on the back of
the CommLink 5 should be set to “Single”.
2. Using 18 gauge minimum, 2 wire cable for power, install
a 24 VAC, 8 VA minimum, transformer for the VCM-X
E-BUS Controller and wire from the transformer to the
VCM-X E-BUS Controller. Then wire from the VCM-X
E-BUS Controller’s 3 wire communications connector or
the CommLink 5’s 3 wire communications connector to
the fi rst VAV/Zone Controller’s 3 wire communications
terminal. Connect all of the associated Non-Modular
VAV/Zone Controllers in a daisy chain format using 18
gauge, 2 conductor shielded cable for communications.
Using 18 gauge minimum, 2 wire cable for power,
install a 24 VAC, 6 VA minimum, transformer for each
Non-Modular VAV/Zone Controller and wire from each
transformer to its VAV/Zone Controller. WattMaster
recommends you use a separate transformer for each
VAV/Zone Controller as stated. As an alternative, it
is allowable to have several Non-Modular VAV/Zone
Controllers share one properly sized transformer (6 VA
per VAV/Zone Controller). Warning: Polarity must be
observed on all of the VAV/Zone Controllers or damage
to the controllers will result. Use 18 gauge minimum,
2 wire cable for all 24 VAC power wiring. Be sure to
maintain polarity on all boards.
3. The Modular System Manager can connect to any VAV/
Zone Controller or to the VCM-X E-BUS Controller.
Use the supplied pigtail cable which has a modular
connector for connection to the back of the Modular
System Manager and wire to any controller on the
communications local loop with communication wire
terminals. A separate transformer is required for the
Modular System Manager. Connect the 2 power wires
from the pigtail connector to a 24 VAC transformer. The
transformer should be sized to provide 6 VA minimum
power. The Communications setting must be set to Lo
Speed Network Mode.
4. The Modular Service Tool SD will connect to any
of the controllers using the supplied cable with DIN
connectors on both ends. The connection point on the
controller is located near the communications connector.
The Communications setting must be set to Lo Speed
Network Mode.
5. The System Manager TS II utilizes a 3 wire
communication terminal block for connection to
any controller on the communications local loop that
has communication wire terminals. A separate
transformer is required for the System Manager TS II.
It has a 2 wire 24 VAC terminal block for connection to
a 24 VAC transformer. The transformer should be sized
to provide 6 VA minimum power and should be
connected using using 18 gauge minimum wire. In the
Settings Menu, enter <63> for the System Manager
Address.
6. Before powering up the controllers, set each VAV/
Zone Controller’s board address to a unique number
from 1 through 58. Address the VCM-X E-BUS
Controller at 59.
