Configuring RMCC,
BEC, Einstein and E2
A BEC, RMCC, Einstein, or E2 is capable of control-
ling eight anti-sweat heater circuits. BECs allow the eight
heaters to be controlled in two different zones, RMCCs one
zone, and Einstein & E2’s eight zones. Each zone requires
its own dewpoint sensor and setpoint(s). A humidity sensor
and temperature sensor may be used in lieu of a dewpoint
sensor.
The following sections outline the procedure for setting
up anti-sweat control in the BEC, RMCC, Einstein, and E2.
For detailed information on system programming, users
should consult the site controller’s user documentation.

BEC and RMCC Page Layout
Each data screen used in anti-sweat setup is shown in
sections to follow. Data ranges for data fields—the infor-
mation supplied in the help prompt lines—are displayed in
brackets and bold type
[-99° - 99°]
either at the heading for
the particu-lar field description, or—when a heading does
not exist— within the body of the description. Suggested or
default values for a particular entry are always shown in
brackets and bold type immediately following the data
range
[-99° - 99°] [-15.5]

Programming the BEC
4.2.1. Input Definitions
From the Main Menu, press ’7 1’ to access the Input
Definitions screen.
Define 16AI or 8IO board and point addresses for the
anti-sweat humidity and temperature sensors. Use the
down arrow keys to locate the following inputs: (ASC
HUM1, ASC TEMP 1, ASC HUM2, ASC TEMP 2) and
the anti-sweat override inputs (ASC #1 OVRD - ASC #8
OVRD). Refer to
P/N 026-1103, Building Environmental
Control I&O Manual,
Section 6.10.1.,
Input Definition
, for
more information.
4.2.2. Output Definitions
From the Main Menu, press ’7 2’ to access the Out-
put Definitions screen.
Define 8RO and/or 8DO board and point addresses for
the anti-sweat heater zones. Use the down arrow keys to lo-
cate the following outputs: (ANTI-SWT 1 - ANTI-SWT 8).
Refer to
P/N 026-1103, Building Environmental Con-trol
I&O Manual,
Section 6.10.2.,
Output Definition
, for more
information.
4.2.3. Dewpoint/Humidity Offsets
From the Main Menu, press ’3 2 1’ to access the
Dewpoint/Humidity Offsets screen.
If the dewpoint cell or relative humidity sensor is
known to read high or low, offsets may be specified in the
Dewpoint Offset and Humidity Offset fields to correctly
calibrate the sensors. Users may enter a value from -20% to
20% or from -20° to 20°.
4.2.4. Outputs Setup
From the Main Menu, press ’3 2 2’ to access the
Anti-Sweat Outputs Setup screen.
Setup data such as heater interval times, names, and
board and circuit assignments are entered in the Anti-Sweat
Outputs Setup screen.
ON/OFF Interval [1 - 999 sec.] [10 sec.]
All anti-sweat circuits pulse heaters ON for a percent-
age of a defined time interval. This interval is entered in the
ON/OFF Interval field. If an 8DO board is being used, the
value should be less than 240 seconds.
