SHIPPING DAMAGE

Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent.

GENERAL

These instructions explain the operation, installation and troubleshooting of the MV4000 Series controller.

All internal wiring is complete. Only attach low voltage field wiring to designated terminal strips.

The MV4000 is for use with units with or without economizers, can be configured for use with heat pumps, and has a dehumidification control feature if an optional humidity controller is connected.

Each unit should be sized to handle the total load of the structure if 100% redundancy is required.

The MV4000 controller is suitable for both 50 and 60

HZ operation, and is fully configurable such that it can be used in virtually any installation. See Controller Programmable Features and Default Settings.

THEORY OF OPERATION

The controller is used to control two wall mount air conditioners from one control system. It provides total redundancy for the structure and equal wear on both units. It can be used with units with or without economizers and it is recommended that both units be equipped alike.

The MV4000 controller can be configured for alternative (lead/lag/lead/lag) sequence, which is default setting. It can be changed to non-alternating (lead/lead/ lag/lag) sequence as required for special applications or user preference.

The MV4000 is equipped with the B alarm board.

Form C dry contact alarm relays are used, offering both NO and NC switching to meet the user’s specific alarm protocol, providing complete flexibility to meet any user's requirements. All alarm actuations are individually indicated on the controller front panel.

There is an Ethernet based remote communication option that can be either factory or field installed. See section on Communication Module.

controller certifications

mounting the controller

Included in the controller carton is the controller and installation instructions.

The controller should be installed on a vertical wall approximately four (4) feet above the floor-away from drafts & outside doors or windows. Four (4) mounting holes are provided for mounting to the wall and 7/8" holes for conduit connections are provided in both the base, sides & top of the controller.

temperature sensors

The standard (local) temperature sensor has 12" leads and comes installed from the factory.

A secondary sensor is located internally on the main controller board and serves as a reference and back-up sensor to the local sensor. Any differential of +/- 12F between the on-board and local sensor will cause the controller to use the local sensor as its point of reference. If the differential is greater than 12F then the controller will check to determine the on-board sensor is reading a temperature that is between the SP (set-point) plus 12F and the SP minus the DB (dead-band) minus 12F. If it is the on-board sensor will become the valid sensor reading and the controller will ignore the local sensor reading. If it is not then the controller will still use the local sensor reading. This is to add additional level of operational capability in the rare event the local sensor fails. If the controller is operating in this mode it is indicated by the lower left decimal point flashing in the display. Note: for purposes of testing when the local sensor is manually driven higher or lower by applying warm or cool water to the probe the on-board sensor is inhibited for the first

30-minutes following power up, or when power is cycled off and back on.

The controller is designed to accept 1 or 2 additional sensors and those have 25-foot leads. The Bard part number for the optional sensor with 25-foot leads is 8612-023. These can be installed as required in the structure to address hot spots, barriers to airflow, etc.

It is recommended that the sensor lead wires be installed in conduit for protective purposes.

The highest reading of any connected sensor will be used for high temperature alarm and the lowest reading sensor will be used for low temperature alarm.

Note: All sensors are polarity sensitive. The copper lead must connect to terminal CU, and the silver lead to AG. Sensors are solid state, not RTD. Use only sensors supplied by Bard. Sensor leads can be extended up to 200 feet. Use 18-gauge twisted pair with soldered connections.

temperature sensor logic

The standard local (LSEn) sensor monitors the temperature at the controller location. If this is the only sensor connected, it will control the temperature read-out, the space (building) temperature, and also be used for

Low and High Temperature alarm functions.

If one or more remote sensors are installed and connected (Rem 1 or Rem 2), the temperature read-out will display and the building will be controlled to an average of all connected sensors. If there is more than 10F difference from the highest to the lowest connected sensor, the actual control will be governed by the hottest sensor for cooling and the coldest sensor for heating.

If multiple temperature sensors are used, the High and

Low temperature alarms will be governed by the average of the connected sensors.

LOW voltage field wiring

The MV4000 is powered from the air conditioners that it is controlling, 24 VAC (18-32V) low voltage only.

Circuitry in the MV4000 isolates the power supplies of the two air conditioners so that no back feeds or phasing problems can occur. Additionally, if one air conditioner loses power, the MV4000 and the other air conditioner are unaffected and will continue to operate normally.

Connect the low voltage field wiring from each unit per the low voltage field wiring diagrams in Section on

“Controller Wiring”. note: Maximum of 18-gauge control wiring should be used. Using heavier gauge wiring can create excessive stress on the control board as door is opened and closed. Create a wiring loop so the door can open and close without stressing terminal blocks.

controller grounding

A reliable earth ground must be connected in addition to any grounding from conduit. Grounding lugs are supplied for this purpose.

controller power-up

Whenever power is first applied to the controller, there is a twenty (20) second time-delay prior to any function (other than display) becoming active. This time-delay is in effect if the controller On/Off button is used when 24VAC from air conditioners is present, and also if controller is in “ON” position and 24VAC from air conditioners is removed and then restored.

Manual

2100-571A

fire suppression circuit

To disable the MV4000 and shut down both air conditioners, terminals F1 and F2 may be used. The F1 and F2 terminals must be jumpered together for normal operation. A normally closed (nc) set of dry contacts may be connected across the terminals and the factory jumper removed for use with a field-installed fire suppression system. The contacts must open if a fire is detected. See appropriate connection diagram - Figures 1, 2 or 3 for this connection. Contacts should be rated for pilot duty operation at 2 amp 24VAC minimum. Shielded wire (22-gauge minimum) must be used, and the shield must be grounded to the controller enclosure.

important note: Older Bard R-22 models employ an electronic blower control that has a 60-second blower off-delay. Current production R-410A models do not use a blower off-delay device and the remainder of this (paragraph) does not apply. In order to have immediate shutdown of the blower motor, in addition to disabling the run function of the air conditioners will require a simple wiring modification at the blower control located in the electrical control panel of the air conditioners being controlled by the lead/lag controller. To eliminate the 60-second blower off-delay, disconnect and isolate the wire that is factory-connected to the “R” terminal on the electronic blower control, and then connect a jumper from the “G” terminal on the blower control to the “R” terminal on the blower control. The electronic blower control will now function as an on-off relay with no off-delay, and the blower motor will stop running immediately when the F1-F2 fire suppression circuit is activated (opened).

staging delay periods

The following delays are built in for both cooling & heating:

Stage 1 0 seconds for blower (if not already on as continuous)

10 seconds for cooling or heating output

Stage 2 10 seconds after Stage 1 for blower

10 additional seconds for cooling or heating output

Stage 3 10 seconds after Stage 2 Stage 4 10 seconds after Stage 3

Note: For cooling Stages 1 and 2, the stage LED will blink for 10 seconds while the cooling output is delayed after that stage is called for. There is also a delay after the stage is satisfied, and after the LED stops blinking, the stage will turn off. There is a minimum 10-second delay between stages 2 & 3, and 3 & 4, but no delayed output when stage is turned on or off, and LED for those stages will not blink.

blower operation

The controller can be configured to have main HVAC blowers cycle on and off on demand; have all blowers run continuously; or have the lead unit blower run continuously with the lag unit blower cycling on demand. Default setting is the blower on the lead unit operates continuously. There is also an option to have all blowers cycle on if one remote sensor is connected, and a temperature difference of more than 5F between any two sensors is observed. This helps to redistribute the heat load within the structure and should reduce compressor operating time.

When any of the stages are satisfied, the stage LED will blink for ten (10) seconds before the stage is actually turned off.

Advance (Swap) lead/Lag unit feature

Pressing the Advance button for one (1) second will cause the lead and lag units to change positions. This may be useful during service and maintenance

procedures. This function can also be done remotely by closing a contact across the Advance terminals on the main board.

accelerate timer feature

Pressing the UP arrow button for five (5) seconds will activate an accelerate (speed-up) mode, causing the normal changeover time increments of days to be reduced to seconds. Example: 7 days becomes 7 seconds. When “ACC” displays, release button.

Whichever LED is on, indicating lead unit will blink over for each second until the controller switches. This is a check for the timer functionality.

humidity control option

Note: This function is not available if controller is configured for heat pump.

The standard air conditioning system can be adapted to perform dehumidification control by addition of a simple humidity controller that closes-on-rise, and is connected to terminals H1 and H2 on the main

controller board. Recommended Bard Part #8403-038 (H600A 1014). Both HVAC units must be equipped with electric heat for this sequence to work properly. See appropriate connection diagram - Figures 1 - 12 for this connection:

1.Temperature control always has priority over dehumidification. If there is any stage of cooling demand active, the dehumidification sequence is locked out.

2.If all stages of cooling are satisfied, and relative humidity is above the set point of humidity controller:

a.The green “Dehumid. Operation” light will come on, and the lag unit compressor and blower will operate until the set point of humidity controller is satisfied (or cancelled by a call for cooling).

b.If the space temperature drops to 67F, the electric heater of the lead unit will cycle to help maintain building temperature. It will cycle off at 69F.

c.If space temperature drops to 64F, the Stage 2 Heating light will come on and the lag unit compressor operating for dehumidification mode will cycle off until the building temperature rises above 65F from 1st stage heat and building load. The green “Dehumid. Operation” light stays on during this sequence, and when Stage 2 Heating light is Off, the compressor is On. The electric heater in lag unit is locked out in dehumidification mode.

Lag unit outputs G, Y1 and Y2 are all switched on during dehumidification sequence. This is true for both alternating and non-alternating controller configurations.

CAUTION

Humidity controller set point should be in 50-60% relative humidity area: Setting controller to lower settings will result in excessive operating time and operating costs for the electric reheat, and in extreme cases could cause evaporator (indoor) coil freeze-up if there are periods of light internal equipment (heat) loading.

COOLING OPERATING SEQUENCES FOR ALternatING LEAD/LAG/LEAD/LAG CONFIGURATION

controller wiring

The MV4000 can be used for controlling two (2) air conditioners with or without economizers. It can also be configured for two (2) heat pumps without economizers. Units with economizers will connect

differently than units without economizers; therefore, it is important to use the correct connection diagram.

There are older style EIFM economizers and newer style ECONWMT economizers that the MV4000 controller system can work with, and also an option for a remote Ethernet communication board. Therefore, it is important to select the correct low voltage hook-up diagram. See Table 1 — Hook-Up Diagram Selection.

security (Locking) feature

The MV4000 controller can be locked such that unauthorized persons cannot make any changes to temperature set points or any other selectable parameters of the controller system.

The ON/OFF and Comfort buttons remain fully active for their normal intent. The Advance/Change/ Save button remains active for the Advance feature only, which allows the position of the lead and lag air conditioners to be swapped (reversed). The Program button remains partially active - allowing the review

of temperature sensor(s) actual reading of temperature, and the current settings/choices that have been chosen. However, no changes can be made when the controller is locked, and if the change button is pressed when in the Program mode, the display will come up showing

“Locd” instead of flashing the selectable choices for that parameter. The default (DEF) reset capability is also disabled when the controller is in locked mode.

Locking and Unlocking the MV4000 Controller:

1.Locking the controller requires using 3 buttons while the controller is in the normal operating (run) mode.

2.Press and hold the Advance/Change/Save button and the Up and Down arrow buttons simultaneously for 20 seconds until the display shows “Locd”.

3.To unlock the controller, press the Change, Up and Down arrow buttons simultaneously for 20 seconds until the display reads “uLoc”.

Generator run / economizer shutdown feature

If desired, the MV4000 controller can be signaled from a standby generator system to lockout (disable operation of the) lag air conditioning system and close economizers if active. This is sometimes mandated if

the generator size is not sufficient to handle the building load (amperage) and that of both air conditioning systems.

A normally closed (NC) dry contact as part of generator controls is required. These contacts must open when the generator is started, and such action will signal the MV4000 controller to this condition and disable lag

air conditioner run function and close economizers if active.

A wire jumper is factory-installed across the Generator Run / Economizer Shutdown terminals. To utilize

the generator run feature, remove the jumper from Generator Run / Economizer Shutdown, and connect the generator normally closed (NC) contacts that will open-on-run generator condition to the Generator Run / Economizer Shutdown terminals.

backup dc power connection

There are input connections available for -24VDC or -48VDC (-20 to -56V) backup power connection. Making this connection will maintain microprocessor operation, front panel display, LED signaling, and alarm relay operation during periods of commercial power outages and when no standby generator is available. This circuit is protected by a replaceable .5A (500mA) 250V fuse.

IMPORTANT: The shelter DC battery power must be connected to the controller and wired as shown in controller wiring diagrams.

The backup DC power connection is polarity sensitive. If polarity is reversed, the controller will not function on backup power, no display and no alarm functions will be evident.

economizer failure alarm

Upon failure of either economizer to open on command or close on command, the Economizer Failure Alarm will open normally closed contacts to signal the failure. To utilize this feature, terminals 8 & 9 must be connected to the shelter alarm panel.

2-compressor run alarm

If both compressors are running at the same time, the 2-Compressor Run Alarm will open indicating this condition.

note: The alarm LED display board is shipped uninstalled to protect it from possible damage during installation of the wiring to main controller board and/ or the alarm board. It is polarity sensitive and is keyed so it can only be installed in correct position.

Note: The LED display board can be replaced if needed independently of the alarm board. Bard part number is 8612-022.

alarm led display board

alarm wiring

Alarm relays can be wired for NO (close on alarm) or NC (open on alarm) strategy.

Alarm relays can be used individually if there are enough available building alarm points, or can be arranged into smaller groups or even a single group so that all alarm capabilities can be utilized.

When multiple alarms are grouped together and issued as a single alarm, there will no off-site indication of which specific problem may have occurred, only that one of the alarms in the group has been triggered. The individual alarm problem will be shown on the LED display on the face of the controller.

Note: All alarm and output relays are Form C (SPDT) dry contacts rated 1A @ 24 VAC.

Note: All alarm relay outputs have 10-second delay in acutally issuing to protect against nuisance alarm signals.

The Power Loss 1, Power Loss 2 and controller alarm relays are all “reverse actuated”, which means they are continuously energized (the NO contact is closed) and switched to NC position upon alarm condition. Therefore, it is important to closely follow the alarm board connection diagrams that follow.

Any alarm feature that is not desired can simply be ignored (not connected).

MIS-2042

note: The LED display board is polarized and will only fit in one direction as shown. It must be fully inserted in order for the controller to function properly.

2nd stage cooling alarm

This alarm output is available for use if desired. It is important to note that in some installations, due to A/C system sizing and internal heat load, that the secondary (lag) air conditioning unit may be called upon to assist the lead air conditioner some of the time. If this is the case, or possibly when additional heat load is added, using the 2nd stage cooling alarm will cause nuisance alarm conditions.

Note: For units with 2-stage compressors, the dual stage cooling alarm activates on cooling Stage 3 initiation. Menu Step 23, CoPr, must be set to “2” for this to occur, otherwise alarm will activate on cooling call Stage 2 causing nuisance alarm.

For installations where it is known that there is 100% redundancy (one air conditioning unit can handle 100% of the load 100% of the time) use of the 2nd Stage Cooling Alarm is a method to issue an alarm signal that the lead air conditioner is down (or not delivering full capacity) and that the lag air conditioner is now operating.

ReFRIgerant pressure alarms

Air conditioners with “J” control module are equipped with an alarm relay that is activated upon high or low refrigerant pressure lockout conditions. Connecting terminals 2 and 3 from the air conditioner 24V terminal block to the matching terminals 2 and 3 on the alarm board will allow these alarms to function.

EmergencY venTIlatioN sequence

For units with economizers, there are two (2) emergency ventilation sequences designed into the controller. Both require the -B alarm board and connection of terminals E and F from the air conditioner 24V terminal block to the matching terminals on the alarm board.

Note: The E and F wiring connections at the 24V terminal block in the A/C units are different for older style EIFM economizers than for newer style ECONWMT economizers. Refer to the appropriate Controller Connection diagrams - See Table 1.

Sequence one requires a refrigerant pressure alarm, coupled with high temperature alarm condition No. 1

(HAL 1 set point). If both of these conditions occur, the economizer in the air conditioner that issued the refrigerant alarm will drive open to ventilate the building.

Sequence two (HAL 2 set point) is activated by high temperature alarm No. 2, and will initiate even without a refrigerant pressure alarm signal. Both economizers will be activated to provide emergency ventilation. This strategy help protect against building overheating if air conditioner(s) are inoperative for non-pressure related reasons (bad compressor, contactor, run capacitor, etc.).

programming instructions

To swap lead and lag unit positions, press the ADVANCE button.

To enter the Program mode, press the PROGRAM button and release it when the message PROG appears on the display. When in Program mode, the DOWN and UP arrows are used to scroll through the programming steps.

A FLASHING display means that the function or choice is “SET”, and the display will alternate between the step function and setting.

To change the setting of any step, press the CHANGE button and the display will stop flashing, allowing change to the setting by using the DOWN or UP arrows. When desired setting is reached, press the SAVE button, and proceed as desired. When done with programming changes, press the PROGRAM button until display stops flashing and room temperature display is shown. If no buttons are pushed within thirty (30) seconds, the controller will automatically revert back to “RUN” mode.

To reset all controller settings to the factory default values, press the PROGRAM button for 10 seconds until display reads dEF.

NOTE: When the controller has the security locking feature enabled, no changes to any selectable features can be made, and the default reset feature is also locked out. All of the programmable features/settings can be reviewed using the Program button and Up or Down arrows, but any attempt to change settings using the Change button will result is display showing “Locd” indicating controller is locked. See section on Security (Locking) Feature.

See next page for Programmable Features, Default Settings and MV4000 front panel label layout.

NOTE: When using the controller buttons to review settings or making changes, push and hold the buttons for approximately 1 second or until the display changes.

Quickly pushing or jabbing the buttons will not allow the controller to respond.
