EPiC™ DDC Controls
EPiC™ DDC Controls
As an option, Mammoth offers factory-programmed
and unit-mounted EPiC DDC controllers for precise unit
operation. They are factory programmed per the appli-
cation, and have a 16-bit processor with 1MB Flash
RAM and 4MB of battery-backed RAM.
The control programs, hand-held human-machine inter-
face (HMI) files and editable set-points are stored on
Flash RAM at the time of download or upon manual
archive initiation.
In the event of a battery-backed memory loss, the pro-
gram, HMI and archived set-points are refreshed from
the archived data in Flash RAM. An on-board, battery-
backed, real-time clock is included to allow for stand-
alone operation scheduling.
The controllers include LED indicators for power, run,
processor error for each control output, Building Man-
agement System (BMS) communication transmit, and
BMS communication receive.
EPiC controllers are capable of BMS network commu-
nication using either BACnet MSTP, Modbus RTU, or
JCI N2 without an external gateway device from 9.6k to
76.8k Baud. They conform to BACnet Advanced Appli-
cation Controller (B-ACC) Standard Device Profile as
defined in ANSI/ASHRAE Standard 135-2012 (BACnet)
Annex L, Protocol Revision 9.
EPiC controllers are also capable of BMS network com-
munication using LonWorks (LonTalk) protocol with an
optional LonCard to only include the required neuron chip.
There are no requirements for LonCard programming.
A sensor/HMI network port allows 5 remote-mounted wall
sensors and an HMI to be connected at the same time.
Wiring diagrams for these controllers are provided on
pages page 46 and page 47.
