Additional Information
Room Sensors
The MPC is design to work with specic sensors. Two
types of sensors may be used:
1. Lstat
2. RNet
The RNet connection is at the upper left of the MPC and
the LSat is at the lower left. Both are four to ve wire
sensors. The MPC comes factory set for the Lstat sensor
at the room sensor jumper. To utilize the RNet sensors
the jumper must be changed to RNet.
The use of the RNet sensor allows for an extra input
into the MPC. The sensors are available with additional
internal sensors possibilities including Humidity, CO2 or
VOC. When using a unit equipped with Climadry Reheat,
a combination temperature and humidity sensor is
required. Refer to ASW section.
It is also possible to use the equipment touch as a wall
sensor if only temperature or temperature and humidity
are required. See the Equipment Touch IOM for specic
instructions on enabling the Equipment Touch internal
sensors. The ASW 6, 7, 8 ase LSTAT sensors. The ASW 13,
14, 15 are RNET sensors.
The LSTAT sensors are the ASW06, 07 and 08. The RNET
sensors are the ASW13, 14 or 15. Additional sensors
included can be humididity and CO
2
. This is designated
by the H and/or C sufx.
Retrotting MPC to Existing Units
The MPC can be added to any ClimateMaster unit with
the CXM, DXM, DXM2 thermostat boards. A retrot
kit has been assembled with the board, the wiring and
additional sensors are required.
LAT
The leaving air temperature is reported to the BNS. LAT
control is not supported.
iGate Communication
On units equiped with a DMX2 board, the iGate functions
are not available when the MPC is installed. The Service
Tool can be connected directly to the DXM2 – to access
the board functions. The MPC does not access these
functions.
Additional Inputs
The AL1/AL2 and EHZ/GND inputs are available with
either type of sensor. Two additional inputs are available
when the Rnet sensor is used. These are Temp/GND and
SW/GND.
AL1/AL2 and EH2 input terminals can accept 0-5VDC,
Thermistor, or dry contact signals. Terminals LAT/LWTL
and LWT/LWTS accept thermistor or dry contact signals.
LAT/LWTL and LWT/LWTS come with leaving air and
leaving water temperature thermistors installed but can
be repurposed. The Lsat terminals can be used for a
additional thermistor input (Gnd/Temp) and SW can be
used as a dry input contact.
The MPC allows custom factory programing of the
various inputs to accomplish various sequence of
operations as the building may require.
Certain options can be added to the MPC programing
after installation of controls system upgrades/changes
are being considered. Consult factory for applicability.
The MPC can be programmed with a 7 day program: the
routine is built into the software.
