The Multi-Protocol (MPC) Heat Pump controller is a dual
purpose controller. It contains the logic to perform as an
advanced customizable thermostat when combined with
a wall sensor and is designed to allow the integration of
water source heat pump equipment into DDC systems.
The MPC Controller has the ability to communicate
through a choice of four widely used protocols:
1. BACnet MS/TP
2. Johnson Controls N2
3. Modbus
4. LonWorks.
The protocol of choice for the particular system is
selected by simply conguring DIP switches on the MPC
Controller with the exception of LonWorks. The LonWorks
option requires an additional Lon option card (LOC).
This exibility allows one controller, the MPC, to be used
in a multitude of buildings which use any of these four
common protocols.
The MPC serves as a node of information processing
between the heat pump and the DDC network. The MPC
commands the heat pump to heat and cool based upon
sensor inputs. The MPC monitors the operation of the heat
pump and communicates the operating parameters to the
DDC network. The MPC will always work in conjunction
with a CXM, DXM or DXM2 controller, which also resides
in the heat pump control box. The MPC has factory pre-
loaded application software which allows optimal control
of the heat pump equipment. The MPC can run in stand-
alone operation as well as with the DDC network. The heat
pump arrives at the jobsite with the factory installed MPC
Controller. The heat pump is ready to run stand-alone and
then can be connected to the DDC network at any time.
Features
System Controls: In conjunction with the wall sensors, the
MPC offers features such as:
• Room temperature sensing.
• Local setpoint adjustment.
• Local override into Occupied Mode.
• LED for alarm status.
• LED for fault status type.
• Heat pump reset at the wall sensor.
• Digital room temperature display.
• Information from the wall sensors can then be reported
to the DDC network system.
• Various sensors such as occupancy sensors, supports
various sensors for occupancy determination. Also
avalable in combination with humidity and/or
Co
2
sensors.
• Supports water to air application or water to water
applications.
• The MPC can be programed with a 7-day schedule.
• One binary Aux output can be programmed to
control various functions.
Communications: The Multi-Protocol communications
provides DDC system flexibility.
• Supports native BACnet MS/TP communications (the
ASHRAE standard protocol for interoperability).
• Supports Johnson Controls N2 communications (for
integration into Johnson Controls Metasys
(DDC systems).
• Supports Modbus communications for integration into
Modbus DDC networks.
• Supports LonWorks communications. Requires LOC
daughter card (PN-17B0012N08).
• Four baud rate levels offer flexible communications
speeds of 9600, 19.2k, 38.4k, or 76.8k baud.
• High speed 16-bit Hitachi Processor with 1024 kBytes
RAM and 4096 kBytes Flash Memory which allows,
if needed, MPC programs to be upgraded and easily
downloaded in the field.
• Removable field wiring connectors for ease of
field service.
• Engineered for quality and reliability.
• Enables building operators to easily upgrade
firmware in the future.
• Program archival feature.
• Supports up to five AWS13,14,15 (Rnet) sensors.
• Supports equipment touch maintenence and
configuration tool.
MPC Controller Overview
Added Features on Gen 7
• Ability to operate in heating or cooling only mode.
• Ability to operate in full time electric or external
heat mode.
• Ability to archive the current control program.
• Input for pressure switch for dirty filter notice
applications.
• Can operate without ASW sensor if so equiped with
an Equipment Touch unit (temperature and
humidity only).
• Can alternate compressor (lead LAG) based on manual
control, timed control or compressor accumulated time
High time compessor becomes secondary or LAG at
beginning of next heat/cool cycle.
• Supports Android based tablet in place of Equipment
Touch (does not support temp/humidity control).
• Selectivly supports zone averaging using up to 5 ASW
wall sensors.
• 17B0012N10 uses new maintenance tool/user interface
(Equipment Touch).
