SECTION 5: COMMUNICATIONS
When multiple SAS products are networked together,
the controllers communicate through MS/TP wiring
arranged in series from one controller to the next.
See Page 12, Figure 5
5.1 WebCTRL®
WebCTRL® comes standard with the Virtual Wall
Controller package. This webbased monitoring soft-
ware allows for quick and easy control of every
device on the MS/TP network chain. Plant layout
graphics, product graphics, scheduling, alarm moni-
toring, parameter trending and much more are avail-
able from the comfort of a desk. Software is installed
on the touchscreen computer and connected to the
local network and all other computers are able to
gain access through this point. The Virtual Wall Con-
troller acts as the IP connection point to the local net-
work.See Section 6 for WebCTRL® details.
5.2 Communications Between Multiple SAS
Products
The controllers from each SAS product must have
MS/TP communications wired in series. Page 12,
Figure 5. Connect the MS/TP (Port 1) terminal on
controller #1 to the MS/TP (Port 1) terminal on con-
troller #2 and so on in a daisy chain fashion. Shield
wires for MS/TP cables should be twisted together,
but not grounded, at all satellite controllers in daisy
chain. Ground shield wire at central panel only.
Maximum of 32 controllers in series. For communica-
tion cable requirements, see Page 7, Section 3.3
A unique MAC address is required for each controller
on the MS/TP network. Set the MAC address using
the Rotary Switches. For help locating these, see the
labeled control board diagram in Figure 3. There are
2 rotary switches. The upper rotary switch is labeled
"1's" and lower rotary switch is labeled "10's". To set
the MAC address for the first 9 controllers, the lower
rotary switch (10's) is set to "0", the upper rotary
switch (1's) is set to the appropriate controller num-
ber. To set the MAC address for controller numbers
10 and up, the setting of the lower rotary switch (10's)
must be combined with the value of the upper rotary
switch (1's). For example: To set the MAC address to
"17", adjust the lower rotary switch (10's) to "1" and
adjust the upper rotary switch (1's) to "7".
NOTE: The Virtual Wall Controller should be set to
"1". Changes to the rotary switches are acknowl-
edged only after the board has been power cycled.
Contact Specified Air Solutions or your SPECIFIED
AIR SOLUTIONS™independent distributor, if more
than 32 satellite controllers are required.

5.3 SettingBaud Rate
To set the baud rate for the MS/TP network on Port 1
configure the board for a baud rate of 19.2K by set-
ting DIP switch #5 to "ON". See chart in Figure 6 for
baud rate settings.
NOTE: Changes to the DIP switches are acknowl-
edged only after the board has been power cycled.
NOTE: Higher baud rates can be used over shorter
distances. The maximum rate of 76.8k can be used
for distances up to 2000ft (609m). A terminating
resistor is required for 76.8k. A baud rate of 38.4k
can be used without terminating resistors for dis-
tances up to approximately 3000 ft.
FIGURE 6: SettingBaud Rate
5.4 Control Board Setup
Universal Inputs and Outputs, Ports, Rotary Switches
and DIP switch must all be configured for the board to
work properly. Reference the labeled control board,
Figure 3, for help locating parts on the control board.
Each Input and Output has a configurable jumper.
For the Universal Inputs (UI) the jumpers are located
next to the input terminals. A diagram of the jumper
configurations is shown on the board.
For the Universal Outputs (UO) the jumpers are
located next to the HOA switches. A diagram consist-
ing of the jumper, the indicator light, the Pot dial and
HOA switch is also shown on the board. Each HOA
switch should be set to AUTO.
Port 1 needs to be configured to operate as the BMS
port. To do this, a combination of the Port jumpers
and the DIP switch configuration is required. To
ensure Port 1 is operating as the BMS/BAS Port,
switch 3 of the DIP switch should be OFF. Switches
6, 7 & 8 should be configured for BACnet MS/TP
m(master) as shown in the diagram on the board.
Each should be set to OFF. Finally, the Baud Rate for
Port 1 is set using switches 4 & 5. It is important to
note that the maximum communication distance
achievable before a REPEATER is necessary is
dependent on the Baud Rate. A maximum Baud Rate
of 19.2 K can be used for distances up to 4000 ft
(1219 m). If the maximum Baud Rate of the Port is

5.5 Sequence of Operations
All control equipment shall operate in stand-alone mode according to its sequence of operation in the
absence of the Virtual Wall Controller.
Occupancy
WebCTRL® shall centrally coordinate the monitoring and control of all equipment. WebCTRL® allows the
user to create plant wide schedules, trend graphs, and reports as well as adjust heating setpoints, pressure
control, cooling and more.
In the unoccupied mode, the Exhaust Fans (EF) and Outside Air Handling Unit (OAHU) shall be off. The
Infrared Heating equipment (IRH) will maintain unoccupied heating setpoints.
A predictive, learning, optimal start routine shall start the Infrared Heating equipment to achieve the target
occupancy setpoint by the start of occupancy.
In the occupied mode, the OAHU shall be cycled on and operate according to its sequence of operation. The
EF's shall be enabled and will operate according to the exhaust fan control routines outlined below.
Description Part Number

VIRTUAL WALL™ CONTROLLER INSTALLATION MANUAL

IRH and OAHU Setpoint Coordination
The IRH shall maintain the space temperature heating setpoint (occupied and unoccupied) according to its
sequence of operations as performed by the IRH controller.
Should the IRH be operating at 100% capacity and not be able to achieve or maintain the space temperature
heating setpoint after the prescribed adjustable runtime (15 min), the discharge air temperature setpoint of
the OAHU shall be raised to supplement the heating capacity of the IRH system. Once the heating setpoints
are achieved, the OAHU shall return to normal operation.
BuildingPressure
In the occupied mode, the OAHU shall maintain the space at the higher of:
1. A positive pressure of 0.01" wc (adjustable) relative to the outside static pressure.
2. The required outside air CFM as measured by the equipment and defined by code or process
requirements.
Unoccupied Free Cooling
In the cooling season, if the night time outside air conditions are suitable and the OA temperature is at least
3°F lower than the space temperature, the OAHU shall be switched on to pre-cool the space.
Preoccupancy Purge
If desired, the system can perform a pre-occupancy purge by staging on the EF's and OAHU prior to the start
of occupancy by a user adjustable time period to ensure sufficient air change. Outside air temperature limits
shall be provided to prevent the purge operation during times when the OA conditions are unsuitable.
Exhaust Fan Control
In the occupied mode, Exhaust Fans shall be enabled and cycle on according to one or more of the following
conditions:
1. Continuous during the occupied mode
2. Upon a rise in space temperature above the cooling setpoint
