MPC Controller Overview

MPC MultiProtoCol DDC Controls

November 19, 2018

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 preloaded application software which allows optimal control of the heat pump equipment. The MPC can run in standalone 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.

MPC Controller Overview

Communications Selection

When the Communications Selection jumper is in the “BACnet over ARC156” position, DIP switch selectors SW1, SW2, SW3, and SW4 are all disabled. When the communications selection jumper is in the “BACnet over ARC156” position, BACnet protocol is selected and the baud rate is also selected to be 156 kbps.

When the communications port is congured for RS-

485 communications, use standard dedicated 22AWG18AWG twisted pair wire.

When the communications port is congured for the

ARC156, use a ARC156 cable available from Automated Logic.

For complete details on wiring, termination, for BACnet MS/TP, refer to ANSI/ASHRAE 135-1995, clause 9.2.2. Refer to the Application Note for the BACnet devices

that you will be interfacing with for specic wiring.

Communications Wiring Instructions

1. Be sure the module’s power is off before wiring it to the ARC156 or RS-485 communications bus.

2. Check the network communication wiring for shorts and grounds.

3. Connect the ARC156 or RS-485 wires and shield to the module’s screw terminals as shown in Figure 9. Be sure to follow the same polarity as the rest of the ARC156 or RS-485 communications network.

4. Power up the module.

5. Proper communications for all protocols

and baud rates can be veried by making

sure the transmit (Tx) and receive (Rx) LEDs are active.

Protocol Congure

The communications port on the MPC has MultiProtoCol

capability which means the MPC can be congured

to communicate via BACnet, Johnson Controls N2, or

ModBus communication protocols. This conguration is

done via the “Communications Selection” jumper and the 4-position DIP switch package (SW1, SW2, SW3, SW4) located on the MPC. The communications port’s baud rate is also set with this same 4-position DIP switch package. See Figure 5 below.

Note: If using ARC156 wiring, then only BACnet protocol can be used. When using RS-485 wiring, any of the 3 protocols (BACnet, N2, ModBus) can be used.

Figure 5: Wiring the ARC156

Figure 6: Communications Selections

THE SMART SOLUTION FOR ENERGY EFFICIENCY

MPC Controller Overview

BACnet Setup – The MPC can be set up to communicate

via “BACnet over ARC156” or “BACnet MS/TP”. Refer to Table 1 for setup.

N2 Setup – N2 must be congured for RS-485

communications with a baud rate of 9600, using 8 data bits, no parity, and 1 stop bit. The MPC is always an N2 slave. Refer to Table 1 for setup.

ModBus Setup – ModBus must be congured for RS-485

communications. Baud rate can be selected from 38.4 kbps, 19.2 kbps, or 9.6 kbps. Refer to Table1 for setup.

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 CO2 . 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.

BACview6 Service Tool and Addressing

Addressing & Power Up

Before setting or changing the module's hardware address, make sure the MPC Controller power is off. The MPC only reads the address when the module is turned on. The MPC has two rotary switches for assigning the module’s hardware address. One switch corresponds to the “tens” digit and the second switch corresponds to the “ones” digit, allowing for hardware- based addressing of up to address 99. For example, if the module’s address is three, set the tens switch to zero and the ones switch to three. The station ID for each MS/TP node must be unique on a MS/TP segment. The MPC’s rotary address switches are used to set this unique ID.

Figure 8: Setting Module Address

After setting the address, turn power on to the MPC. The Run, Error, and Power LEDs should turn on. The Run LED should begin to blink and the Error LED should turn off.

Note: Set address for heat pump #1 (HP-1) at 02 per typical BMS naming conventions. All other heat pump addresses should be assigned as HP# + 1.

Changing the device instance when using a network of more than 99 MPC units

Note – This applies to Gen4 MPC’s only. When using

Gen3 MPC’s, to allow for more than 99 unique addresses, a special request should be made through the Product Management and Applications team.

The Gen 4, 5 and 6 MPC allows the device instance to be changed using the BACview6 service tool. This feature allows an installation with more than 99 MPCbased units to be set and managed on-site rather than factory preset.

In order to change the device instance, the MPC must be powered up. Connect the BACview6 service tool to the MPC using the local access port. When the main screen appears, scroll down to “Manual Control” using the down arrow and press “Enter”;

At the “Manual Control” screen, press “Enter” with

“Unit Conguration” highlighted and again with “BAC-

Equipment Touch Service Tool Overview

The Equipment Touch (Figure 12) is a touchscreen device with a 4.3 Inch color LCD Screen that is connected to an MPC GEN 7 Controller Unit. It will allow access to most all internal control/ status points, alarms that would normally require access to the system server (WebCNTL) to access. It is a replacement for the BACVIEW 6 service tool previously used for this purpose, but has increased functionality. Equipment Touch does not currently support water to water applications. The Equipment Touch (or EQT) can also function as a wall sensor

providing Temperature and Humidity data to the Controller when congured correctly. The

EQT connects to the MPC Controller’s RNet port in the same manner as the RNET Wall sensors and can reside with up to 5 RNet Sensors. Each MPC GEN 7 controller can support up to 5 RNet Sensors and one EQT (Figure 13 and 14).

Figure 16:

MPC LED Codes

THE SMART SOLUTION FOR ENERGY EFFICIENCY

MPC MultiProtoCol DDC Controls

November 19, 2018

The MPC Controller has the following LEDs:

Power - indicates when power is on. Run - blinks when the processor is running. Error - lights when an error is detected. Receive (Rx) - lights when the Comm Port receives data. Transmit (Tx) - lights when the Comm Port transmits data. Digital Output - lights when the associated digital output turns on.

LED Power-Up Sequence

During power-up, the module goes through an initialization and self test sequence.

Proper module power-up can be veried by observing

the LEDs as follows:

1. The Run and Error LEDs turn on and begin blinking.

2. The Error LED then turns off.

3. The Run LED continues blinking.

Note: The Error LED ashes three times in sync with

the Run LED when the module is being formatted.

The Run LED should never stop ashing. If it stops ashing for 1.5 seconds, the watchdog timer will reset

the module.

Overcurrent Protection

The MPC Controller is protected by internal solid state polyswitches (polymeric PTC, resettable overcurrent protection device, also called PPTC) on the incoming power. The overcurrent protection circuitry is a positive

temperature coefcient (PTC) thermistor that increases

in resistance as it warms up and stays in that mode until the power is removed. Once the power is removed, the polyswitch resistance lowers to operational level as the device cools down. After power has been re-applied, the unit will operate properly if the fault condition has been removed.

It is not necessary to remove power on the communication line in order to reset the solid state overcurrent circuit. Once the power level is low enough, the overcurrent circuit cools down to operating temperature. A blown polyswitch can indicate incorrect wiring if the polyswitch is blown during installation. Generally, a blown polyswitch indicates a power surge was received by the board.

Digital Output LEDs

There are 5 digital outputs on the MPC. One output

(AUX) can be custom congured to control an external

device (1amp at 24VAC.). G, O, Y2, and Y1 are required to operate the heat pump and are connected to the CXM, DXM or DXM2 board.

and Y2 (DO2) are the outputs for compressors stage 1 and 2. Y1 is connected to Y terminal on the CXM/ DXM/DXM2 and if the heat pump is dual stage, Y2 is connected to a second CXM Y input or Y2 on the DXM/DXM2.

Y1 and Y2 are off when the zone temperature is between the heating and cooling set points. As the zone temperature rises above cooling set point or below heating setpoint, Y1 is energized at 50% PID and Y2 is

energized at 75%.

Troubleshooting Tips – If the BMS is having trouble

communicating with the MPC, check the following items before contacting technical support.

• Make sure the MPC wiring is correct. Make sure all color codes match and that no wire strands are shorting over to other terminals.

• Make sure the MPC and other network controllers have power and are turned on. Make sure all equipment have power and LEDs lit with no solid error light. Some devices, especially communication devices, receive power from a source other than a power cable or adapter. Some panels can be reinitialized by resetting the panel.

• Verify operation of all LEDs: RX, TX, Power, Run, DOs and error.

• Make sure that all jumpers are set to default and that there is nothing jumped on the format pin.

There is also a load sharing mode which permits swapping the primary status of Y1 with Y2 depending on compressor run time. The low time compressor becomes primary and the high time compressor assumes secondary status.

Note: All 5 digital outputs have associated LEDs to indicate operating status. If the digital output is on, then the associated LED will be on.

Occupied/Unoccupied Changeover – When the

MPC is in the stand-alone mode of operation, the MPC defaults to the occupied mode of operation. Occupancy changeover may be provided through the communications network.

Water -to-Water Start Up Check

1. Unit powered up and running.

2. LED check: Rx, Tx, Power, Run and no solid red error led.

3. Program initializing schedule status for Occupied Mode (default) or Unoccupied Mode to determine set point range. Occupied set points will be defaulted to 60 cooling and 105 heating. If a schedule is implemented, the unoccupied set points will default to 80 cooling and 85 heating.

4. The Program will determine if the unit is either a Master or Slave.

5. The Program will control the water temperature based on the Entering Water Temperature (EWT) load sensor. This can be changed to control based off of the LWT via BAS or BACview6 service tool.

6. The Program will check for which water temperature set point to use based on Heating Mode or Cooling Mode determined by the state of the RV.

7. In a water to water application, the mode has to be manually changed via Bacnet or with BACVIEW6 service tool. If it is in heating, it will permanently stay

in heating mode until it is changed to specically

cooling mode.

8. Like water to air, Y1 will come on a 50% and Y2 at 75% and not off until the EWT/LWT conditions have

been satised.

9. 5-minute delay is built in between compressor cycles.

10. While the unit is on, the program will continue to monitor the CXM/DXM/DXM2 board for faults. If an event of a fault occurs and the unit is in lockout mode, then the relay will close (IN1/AL1/AL2/GND) and the fault code is transmitted via EH2 output to the EHZ input on the MPC. This is available through BAS network points. A history counter will also keep track of past and present faults which can also be seen via BAS or BACview6.

11. The MPC can also function in metric mode (Celsius mode).

Water-to-Air Startup CheckEquipment Touch Method

2. Read the Zone Temperature and adjust the Zone Heating Setpoint at least 2 ° above the ambient zone temperature. (You can use the RNet Sensor or the Equipment Touch for this operation). You should be able to observe the “Heat PID” Icon start increasing as the MPC is set to go into a heating cycle. a. When the PID value increases above 30% the FAN ICON for the Supply Fan will appear. b. When the PID rises above 40% the RV ICON will appear indicating the Reversing Valve is on. c. When the PID gets to 50% the Compressor C1 will turn on after a 2 minute delay. You should see the C1 ICON after the delay. d. If the Heating unit is wired to the unit and thus not heating, the PID will continue until it reaches 75% and then you should see Compressor 2 or C2 ICON appear. If the PID is allowed to rise it will trigger the Emergency Electric Heat (AUX) output when it goes above 90%. This assumes heat demand has not been satised. e. Decrease the Heating Setpoint 2° below the Zone Temperature and the Heating PID will begin to move downward. f. Once it falls below 90%, the ”AUX” output will turn off and below 75%, C2 will turn off. g. When it falls below 50%, the compressor output C1 will turn of and once it falls below 40% the Supply Fan will turn off.

3. Read the Zone Temperature and adjust the Zone setpoint at least 2° below the ambient Zone Temperature. You should be able to observe the Cool PID start increasing as the MPC is set to go into a Cooling cycle. a. When the PID rises above 40% the FAN ICON will appear indicating the Fan has cycled on. b. When the PID gets to 51% the Compressor C1 will turn on after a 2 minute delay. You should see the C1 Icon after the delay. c.

Occupancy Settings: These control points are used

to set occupancy. a. Occupancy (All Generations) – This point (BV:12) controls whether the unit is in occupancy or is unoccupied. It is normally defaulted to occupancy. It can be set and overridden via the Equipment Touch or from the BMS control program (WebCNTL). b. Occupancy Override (Generation 7)- is a digital input BI:8 used to input a signal from an external motion sensor to override the occupancy. For this to function OCC/Dirty Filter Sens BV:59 must be set to OFF. c. Network OCC Override (Generation 7)- BNI is used via the Network to override the occupancy status of the MPC unit.

RNet Sensor Setup (Generation 7 only): The Gen7

MPC is capable of averaging up to 5 ZS Sensors together over the RNet link. Use one ASW15 and up to 4 ASW13 sensors. If you wish to use the sensor alarm feature you must enable the appropriate alarm enables so that the MPC logic knows how many RNet Sensors are present. a. RNet Sensor 1 Alarm Enable- Checking this will tell the sensor alarm logic to expect a valid sensor to be present at Address Sensor Address 1. b. RNet Sensor 2 Alarm Enable- Checking this will tell the sensor alarm logic to expect a valid sensor to be present at Address 2. c. RNet Sensor 3 Alarm Enable- Checking this will tell the sensor alarm logic to expect a valid sensor to be present at Address 3. d. RNet Sensor 4Alarm Enable- Checking this will tell the sensor alarm logic to expect a valid sensor to be present at Address 4. e. RNet Sensor 5 Alarm Enable- Checking this will tell the sensor alarm logic to expect a valid sensor to be present at Address 5.

2. Air Duct Mode (All Generations): Air Duct Mode (ADM) allows for the control of Zone Temperature based on the return air temperature as sensed in the air duct. To activate ADM turn (BV:41) to “ON” and

BV:44 to “ON”. This requires a 10KΩ type II Duct

Sensor brought into the MPC unit across the TEMP Input and GND Input on the LSTAT Connector.

3. Cooling Only or Heating Only Setup (Generation 7 only): For applications in which is desired to run

in a heating or cooling only mode use the following control points to accomplish this. a: Heating Mode Enabled- (BV:53) will enable the Heating Mode when checked. It defaults to checked so Heating Mode is enabled on startup. Useful when you wish to run in a Cooling only mode as it allows the turning off, of the Heating Mode. b: Cooling Mode Enable – (BV:54) will enable the Cooing Mode when checked. It defaults to checked so Cooling Mode is enabled on startup. Useful when you wish to run in a Cooling only mode as it allows the turning off, of the Cooling Mode.

4. Load Balancing Mode (Generation 7 only): Denes

the mode of operation for the runtime balancing of a 2 Compressor application. The modes are set by entering the following in (AV:59): a: AV:59 = 01- Runtime comparison mode - The compressor with the least runtime becomes the stage 1 compressor while the high time compressor becomes the stage 2 compressor. b: AV:59 = 02- Manual C1 is Stage 1, C2 is Stage. c: AV:59 = 03- Manual C2 is Stage 1 and C1 is Stage 2. d: AV:59 = 04- Time Toggle- C1 and c2 swap stages every 12 hours dependent on demand.

5. Compressor Shutdown (Generation 7 only):

There are times when it is desired to disable the compressor via the BMS. This is accomplished by Turning (BV: 52) to “OFF”.

6. Manual Setpoint Adjust (All Generations): Sets

the maximum amount (degrees) by which the user can adjust the zone's setpoints from a zone sensor.

The adjustment range is dened as +/- the value of

Manual SP Adjust. Example: If Manual SP Adjust is = 2 the adjustment range would be +/- degrees from the Master Zone Temperature (72°) or from 70° to

74°. You enter the Manual setpoint value via (AV:37) or AV:44 depending on your temperature setting (F° or C°).

7. Dirty Filter Detection Setup Options (All

Generations): All Generations of the MPC can

use Time to determine the when to replace the

air lter. Generation 7 can also use an external air pressure sensor in addition to xed Time method to determine when to replace the air lter. All

Generations default to Time Mode which is nominally set to 1500 Hours. This of course can be changed via (AV: 30). Setup for Air Pressure sensor is covered below: a: Dirty Filter Sensor- Setting (BV:59) to “ON” allows Dry Contact Input 6 (SW, GND) to function as pressure input. This requires a pressure switch on the output side of the return air lter. (User supplied) b: Dirty Filter Mode: Set (BV:60) to Pressure.

8. Conguring the Supply Fan (All Generations): (AV:33) is used to control the action and behavior of the supply fan. 1 => FAN is “ON” by demand, Occupied or Unoccupied. 2 => FAN is “ON” while Occupied and ON by demand in unoccupied hours. 3 => FAN is ”ON” all the time.

9. Test Mode (All Generations): Test Mode is used to test the output functions of the MPC unit This

conguration will only remain active for 30 Minutes.

To put the Unit into Test Mode, turn on (BV:34). Once in Test Mode the following can be tested in the indicated order. 1: (BV:28) Supply Fan Manual “ON” 2: (BV: 30) C1 Manual “ON” 3: (BV: 31) C2 Manual “ON” 4: (BV: 32) AUX Manual “ON” 5: (BV: RV) Manual “ON”

10. Input 5 and 6: (Generation 5-7): These Generations

allow the user to use Input 5 (TEMP, GND) and Input 6 (SW, GND) for added features such as Temperature monitoring, or current switch sensing applications. With RNET Mode (BV:44) “ON”, inputs 5 and 6 will

monitor eld supplied 10KΩ type II thermistors via

Aux5 Temp (AV:50) and Aux6 Temp AV51. If a dry contact input is desired, activate Aux% CFG, BV:46 and /or Aux6 CFG, (BV:47). This will allow the user to monitor switch closure status at Aux%, ((BV:42) and / or Aux6, (BV:43).

This function is only available with the following sensors (ASW 13, 14,15). Not compatible with LSTAT Sensors (ASW 09, 10, 11).

11. Master / Slave Setup (All Generations): Before attempting this setup, ensure no wall sensors are connected to the slave units and that the Building Management system (WEBCntl) is capable of mapping points between units.

This method applies for 1 master and 1 slave but is scalable for 1 maser and multiple slave units.

1: Turn on the following point in the potential Slave(s) unit BV:16 ➛ “ON”, this makes the unit a slave. Identify the following points in the Master Unit. a: Zone Temp Status (AV:34) b: Actual HTSP (AV:2) c: Actual CLSP (AV:1) d: Occupied Status (BV:11) 2: Identify the following Slave(s) Points. a: Master ZT (AV4) b: Slave HTSP (AV9) c: Slave CLSP (AV10) d: Occupied Mode(BV12) 3: Map the Master Points to the Slave points. a: Zone Temp Status (AV:34) ➛Master ZT (AV4) b: Actual HTSP (AV:2) ➛ Slave HTSP (AV9) c: Actual CLSP (AV:1) ➛ Slave CLSP (AV10) d: Occupied Status (BV:11) ➛ Occupied Mode(BV12) 4: Once the mappings are complete, verify that the slave Actual CLSP, AV1 and the Actual HTSP, AV2 match those of the master unit. This forces the slave(s) to mirror the operation of the master unit.

12. Using Equipment Touch as a Wall Sensor: In order to use the Equipment Touch as the Wall Sensor,

it must rst have the internal Temperature and

Humidity sensors enabled so they can transmit this data. To do this, navigate to the Sensor setup menu in Equipment Touch.

MPC Wall Sensors

ASW sensors are wall-mounted temperature sensors for use with the MPC controller with Water-to-Air units. The ASW is available in 3 different models to allow for

application exibility. Features such as room temperature

sensing, digital LCD readout, set point adjustment, override pushbutton, heat pump reset, lockout recognition, fault type, LED indicator, cosmetics and occupancy status can be supplied by the different types of ASW wall sensors. The ASW wall mounted sensors

are low prole, which provides a distinguished look for

building architects and engineers.

The three different types of ASW wall sensors feature easy to use analog to digital connections on the MPC.

With only 4 to 5 wire connections, the eld technician

can easily troubleshoot the ASW to determine if it is operating properly.

The ASW15 displays zone temperature, heating setpoint, cooling set point. And if so equiped will display sensed values of humidity, CO2 and VOC's.

Room temperature is measured using a 10k thermistor and can be indicated on an easy to read LCD display (with display only wall sensor). The set point adjust is a slide potentiometer which provides an analog output and is available with a Warm/Cool legend imprinted on the unit's base. The override is a momentary, normally open, push contact.

ASW wall sensors are suitable for direct-wall mount or electrical box mounting. Terminations are easily made at the screw terminal block located on the wall sensor back plate.

ASW 13,14,15 Wall Sensors (RNET Sensors)

To wire and mount a ASW13-15 Sensor

PREREQUISITE: The RNet cable is wired to the controller. The shield wire and the ground wire should be inserted into the controller's GND terminal.

1. Turn off the controller's power.

2. Pull the backplate off the RNet Sensor. You may need to turn the setscrew in the bottom of the sensor clockwise until you can remove the backplate.

3. Pull the RNet communication cable through the large rectangle in the backplate.

Figure 18:

8. Insert the other 4 wires into the RNet Sensor's screw terminal connector. If wiring 2 cables, insert like colored wires into each terminal.

Push Button Override (if equipped)

During the Unoccupied Mode of operation, if the “Override” button on the ASW14 or ASW15 sensor is pressed for 1 second, then the MPC switches to the Occupied Mode of operation and the ASW LED will turn ‘on’. Control is now based upon occupied attribute values. The occupant will acquire 60 minutes of override for each time the "Override" button is pushed; with a maximum of 180 minutes of override time. If the “Override” button is pressed and held for at least 3 seconds during the override operation, then the override period is cancelled and the MPC is returned to Unoccupied Mode of operation.

To override the Unoccupied Mode: Press override button for 1 second. The LED indicator on the ASW wall sensor will turn ‘on’ to indicate occupied status. The controller goes into Occupied Mode for 60, 120, or 180 minutes, determined by the number of times the override button is pressed by the occupant. To increase the override time: If override time has not expired, press the override button for additional minutes of override time. The maximum override time will always be 180 minutes. To cancel override: Press and hold the override button for 3 seconds or more. The override time is cancelled and the ASW LED indicator will turn off. The MPC will return to Unoccupied Mode.

Reading Lockout Code at ASW Wall Sensor

If a heat pump experiences a lockout condition (for example, “high pressure” refrigeration failure), a corresponding code will be displayed at the wall sensor (providing a sensor with LED/display is used). See CXM or DXM Application Manual for detailed description of operation and fault types.

The Lockout code will be displayed as long as the alarm relay on the CXM or DXM is closed, meaning that the CXM or DXM remains locked out. When the CXM or DXM is reset from Lockout Mode, the ASW LED/display will return to indicating “Occupied” or “Unoccupied” mode.

Note: If the MPC Controller is connected to a dual compressor heat pump with 2 CXM controls, the wall sensor will only display the lockout information with regards to the CXM which is connected to compressor stage 1. Lockout information from the CXM controlling the second stage compressor will never be displayed. If the MPC is connected to a dual compressor heat pump with 2 DXM controls, the wall sensor will always display the lockout code for the compressor stage 1,

even if the stage 2 compressor locks out. If the second stage DXM Control locks out, a warning code, of some type will always be displayed at the wall sensor.

Resetting Lockout at ASW wall sensor

The “Override” or “Manual On” button can be used to reset a heat pump lockout at the wall sensor.

a) The LED or indicator will indicate a lockout code. b) Push the “Override” or “Manual On” button for

1 second.

c) The MPC will interpret the button a manual reset and

the MPC will reset the heat pump. d) The MPC will return the heat pump to normal operating mode.

Note: If the MPC was in Unoccupied Mode before the heat pump lockout, then once the heat pump is reset via the “Override”/”Manual On” button, the MPC will reset (as stated above) AND will now have 60 minutes of override time.

Setpoint Adjust

The setpoint adjust is a slidepot which provides an analog output and is available with a Warm/Cool legend imprinted on the unit’s base. The user can adjust the setpoint by up to the negative user set value (default

-5) by sliding the adjust to the “cool” position. The user can adjust the setpoint by up to the positive user set value (default +5) by sliding the adjust to the “heat”

position. The setpoint adjust operation can be modied

by changing the function block programming within the MPC (See Water-to-Air Sequence of Operation).

Fail Safe Mode

If the connections between the MPC and ASW wall sensor are interrupted or disconnected, the MPC will force the digital outputs to the “Off” state. When the connections to the wall sensor thermistor are restored, the MPC resumes normal control.

Android App Instalation

This section covers the installation and setup of the Android Application from OEMCntl that allows an Android capable tablet/Phone to replace the physical Equipment Touch module. The tablet/ phone must have an available USB connection. Most all phones will require a micro or sub micro USB to standard USB adapter. (See Figure 22.)

Required Components:

Tablet Model Used: RCA Galileo PRO

Operating System: Android 6.0 (Marshmallow).

USB Cable: AAPPLDRKIT KIT, SW, MPC, APPLDR/ VBAVIEW/ EQ TOUCH

App: Equipment Touch(OEM), Available at Google Play store. WWW.play.GOOGLE.com

Vendor: OEMCntl, Cost: $29.00

6. At this point you can use the Tablet or Phone to set up and monitor the MPC just as if it had an Equipment Touch Screen attached.

7. One nal note: Equipment Touch has built in Temperature and Humidity Sensors allowing it to function as a Wall Sensor. Obviously, the Tablet/ Phone does not so it cannot function in this mode.

Figure 22: USB Dongle and Cable

Installation

1. The rst step is to go to play.GOOGLE.com (Google Store) and download the Android

Equipment Touch application on to the Tablet or Phone to be used in this application. Note: Each individual device to be used must have a separate license. At this point in time, the license cost is $ 29.00 per device.

2. Once the Equipment Touch Application is installed, Connect the USB dongle included in the AAPPLDRKIT ( See Figure 1.)to the Tablet or Phone (As stated before, the phone may require an Micro USB to USB adapter. See Figure2.)

3. Connect a cable from the MPC USB port to the Dongle.

4. Launch the Equipment Touch Application.

5. When the app starts it will bring up a device list in which you will click on the USB Device. The App will begin to load and will then bring up the Main Equipment Touch menu.

THE SMART SOLUTION FOR ENERGY EFFICIENCY

Q. Why does the set point go to 45°F in heating

mode 5 minutes after unit startup?

A. This is the default condition if there is not a valid

resistance between the GND and SW terminals on the MPC. IF this occurs, check the MPC for loose strands of copper or a missed wire.

MPC Technical FAQs

Q. My unit is not communicating on the network?

Why?

A. Verify that all baud rates, protocol and

communication selections are correct. Then verify

that the Tx and/or Rx leds are ickering. Make sure

that the addressing is correct, unique and not sharing a same address as another controller.

Q. Why is my compressor, fan or RV not energizing?

A. First wait 5 minutes after startup, if the unit has not

yet started, check the out LEDs on the MPC. If they are OFF, make sure that the unit is not in unoccupied mode, if any of them are ON and you still have to activity, verify that you have 'R' wired to the 'R' on the unit controller. If not, jump 24Vac to 'Y', 'O', or 'G' and see if they are energized. If not, contact tech support.

Q. I replaced a CXM/DXM control board and when

I applied power the MPC board was destroyed, Why?

A. By default the AL1 and AL2 terminals are powered by

R (24Vac) on the CXM/DXM. If the JW1(CXM/DXM2) or JW4 (DXM) jumper is not cut BEFORE APPLYING POWER then the 24Vac is going from AL2 (CXM) to Gnd (MPC) and that will destroy the board. Cutting the alarm jumper makes the contact dry thus no voltage will be present when powered. The jumper is pre-cut and this only applies on replaced CXM/DXM/ DXM2.

Q. Why does the alarm relay indicate the unit is in an

alarm state on the BMS but not at the CXM?

Q. Why is my temperature reading incorrectly than

the actual temperature?

A. Make sure that the gain jumper is set in the OFF

position. The jumper puts the temperature on a sharper curve meant for water to water applications. Also, make sure that the sensor is in a reasonable location and not right in front of the airway of the unit.

Q. Why is my RNET sensor all buggy?

A. Make sure that you move the jumper from LSTAT

to RNet.

Q. Can a thermostat be used with MPC?

A. No, ASW… sensors must be used.

Q. What type/size of wire do the ASW… sensors

require?

A. Typical thermostat cable is suitable 22 to 18 gauge.

ASW08 sensor requires 5-conductor all others require 4-conductor.

Q. Is temperature averaging available?

A. The jumper IN1 on the MPC is set to 0-5Vdc instead

of dry. Jump back to dry contact to resolve this issue.

Q. Can I use another sensor besides the ASW?

A. A 10k type 2 tempeature thermister can be

connected to the RNet terminals. Connect to temp and ground. Plus connect a 2.4k 1% resistor between SW and ground. Thermostats will not work with the MPC.

A. Yes using the RNet sensors. Up to ve sensors may

be daisy chained. One ASW15 and up to 4 ASW13

can be connected. Wire to ASW15 rst and then to

the ASW13’s. Address each ASW13 with a unique address.
