2.0 Sequence of
Operation
2.1 States of
Operation
The makeup air control system operates the supply fan, the exhaust fan, the intake dampers, the energy recovery wheel, DX cooling, and gas or electric heat to maintain a set of discharge air temperature control setpoints.
The unit discharge air temperatures fall within the following three categories:
1. Unit supplies neutral temperature air that does not affect space conditions.
2. Unit supplies cold temperature air to provide space cooling.
3. Unit supplies hot temperature air to provide space heating.
NOTE:
Heating applies only when a unit is ordered with a gas or electric heat section. Heating is included in all control instructions.
The sequence is broken into five primary states of operation.
The unit can switch between states based on the following:
•
Controller Display
• th-tune Space Control Device (Option CL78)
•
Building Automation Command (Option BHB7 or BHB8)
•
Automatically based upon sequence of operation.
The unit state is the primary determination of individual component function.
1. Off
The unit supply fan and all associated mechanical equipment is OFF in this state.There are no associated sequences of operation in this state. The unit will only switch to the OFF state when the state is manually selected through the th-tune device (Option
CL78), unit display, or building automation network communication point. Upon initial power, Unit OFF is the default state.
2.
Off / Alarm
The Off / Alarm state can only occur from a sequence
“failure”. The unit will switch to this state from the heating, cooling, or auto state. The unit will stop all mechanical operation until the “failure” condition(s) are resolved. The output will be OFF. Upon resolving the failure, the unit will return to heating, cooling, or auto state. Alarms can also be cleared by resetting power to the unit.
3. Heat (optonal)
From the th-tune device (Option CL78), controller display, or BMS, the heat state can be selected. The supply fan will run and mechanical heating, dampers, and energy recovery equipment will be operated to maintain heating sequence of operation.
The unit will not automatically switch to other states except Off / Alarm.
4. Auto
From the th-tune device (Option CL78), controller display, or BMS, the auto state can be selected. Upon initial selection of the auto state, the unit will be in the auto-heating state (if equipped) whenever the outdoor air temperature is below 65°F(18°C), otherwise the unit will be in the auto-cooling state. The unit will change to auto cooling/auto-heating state whenever the temperature crosses the changeover setpoint for more than 15 minutes or is more than 5°F(2.8°C) beyond the changeover setpoint.
The unit mechanical function is exactly the same in either cooling or heating state, other than the sequence’s ability to change states. NOTE: The unit switches between heating and cooling based upon outside air temperature. Space temperature does not dictate heating or cooling mode.
5. Cool
From the th-tune device (Option CL78), controller display, or BMS, the cool state can be selected.
The unit supply fan will run and mechanical cooling, dampers, and energy recovery equipment will be operated to maintain the cooling sequence of operation. The unit will not automatically switch to other states except Off / Alarm.

2.2 Modes of
Operation
When the unit is called to operate in the auto, heating, or cooling state(s), the unit will function in one of two modes: occupied or unoccupied. The unit will run in occupied or unoccupied mode based upon one of the following three user selected commands:
1. Internal Time Clock Schedule Selects Occupied or Unoccupied Mode.
2. Physical input point (ID4) (Contact closed = Occupied)
3. Building Automation network variable (LonWorks
®
or BACnet
®
)
From the display, the user will select the mode control type. All other input methods are ignored.

NOTE 1. -
Intermittent operation of the supply fan will be based on an increased space cooling setpoint and a decreased space heating setpoint during the unoccupied mode.
Supply Fan Control:
Occupied Mode
When the unit is called to be in occupied mode, the supply fan will start. If the unit is configured with a 100% outside air damper, the damper actuator is electrically interlocked such that the supply fan cannot start until the damper is 80% open.
When the Supply fan is commanded OFF, any active heating or cooling operations will be shut down and the supply fan will stop after an adjustable time delay.
The rate is controlled by unit state, mode, and the selection of one of six sequences of operation:
1.
High - Low Fan Speed Control (VFC1)
The variable frequency drive is commanded ON from NO1. There are two fan speed states - active heating/ cooling and fan only. When the fan is ON and the system is in either the space heating or space cooling mode, the unit will operate on high fan speed. When the fan is ON and the system is not in either the space cooling or space heating mode, the supply fan will operate on low fan speed.
2.
Duct Static Pressure Control (0.0” to 2.5” iwc) (Option VFC3)
The variable frequency drive is commanded ON from NO1. The fan modulates between the user adjustable minimum and maximum fan speed setpoints using a PI loop to maintain the duct static pressure setpoint, +0.5”iwc default.
3.
Building Static Pressure Control (-0.5” to 0.5” iwc) (Option VFC4)
The variable frequency drive is commanded ON from NO1. The fan modulates between the user adjustable minimum and maximum fan speed setpoints using a
PI loop to maintain the building static pressure setpoint, +0.1”iwc default.
4.
Summer/Winter Constant Volume (Option VFC9)
The variable frequency drive is commanded ON from NO1. The unit ramps up to a user set supply fan speed setting. There are two individual supply fan speed % setpoints, one for heating and one for cooling. When the Unit is in Space or Neutral air Heating, the supply fan will use the heating speed % setpoint. When the unit is in any other mode, the supply fan will use cooling speed % setpoint.
5.
External Source 0 to 10 vdc (VFC2)
The variable frequency drive is commanded
ON from NO1. The supply fan will modulate from 0-100%. The speed control signal is sourced by others and a direct connection of a 0 to 10 vdc input to the unit terminal strip must be provided.
6.
BMS Source (VFCC)
The variable frequency drive is commanded ON from NO1.
The dampers will modulate from 0-100%. The speed control signal is sourced by others, communicated via a BMS network and a connection to either a BHB7 or
BHB8 BMS card is required.
A 30-second acceleration and deceleration rate for the supply fan to ramp between the minimum and maximum motor frequency is factory set via the unit variable frequency drive.

3.3 Intake Damper
Control
When configured for space control, the supply fan operation will be intermittent based on the zone temperature. See Temperature and Humidity Control section, Paragraph
3.9, for space control and setpoint definition.
The exhaust fan provides a volume of air expelled to outdoors. The rate is controlled by unit state, mode, and the selection of one of four sequences of operation.
Exhaust Fan Control: Occupied Mode
1. High - Low Fan Speed Control (EFC1)
The ECM motor is commanded via Modbus communication. There are two fan speed states - active heating/cooling and fan only. When the fan is ON and the system is in either the space heating or space cooling mode, the unit will operate on high fan speed. When the fan is ON and the system is not in either the space cooling or space heating mode, the supply fan will operate on low fan speed.
2. Building Static Pressure Control (-0.5” to 0.5” iwc) (Option EFC4)
The ECM motor is commanded via Modbus communication. The fan will operate between the user adjustable minimum and maximum fan speed setpoints, and modulate using a PI loop to maintain the building static pressure setpoint, +0.1”iwc default.
3. Supply Fan Tracking (Option EFC7)
NOTE: This option is not available with supply fan control option External Source 0 to 10 vdc
The ECM motor is commanded via Modbus communication. This option will use an offset variable to subtract from the commanded supply fan speed. The difference between the supply fan speed minus the value of the offset variable will be the active exhaust fan speed setpoint.
4. Constant Volume (Option EFC9)
The ECM motor is commanded via Modbus communication. The unit ramps up to a user set exhaust fan speed setting. There are two individual exhaust fan speed
% setpoints, one for heating and one for cooling. When the unit is in Space or
Neutral Air Heating, the exhaust fan will use the heating speed % setpoint. When the unit is in any other mode, the exhaust fan will use cooling speed % setpoint.
The exhaust fan has a 30-second acceleration and deceleration rate to ramp between the minimum and maximum speeds.
The exhaust fan is normally OFF in the unoccupied mode. The unit exhaust fan will be permitted to operate in the unoccupied mode if the unit is configured for 100% outside air. Exhaust fan operation will also be permitted when the intake damper control options
GF1, GF2 or control by BMS is selected and the unoccupied ventilation enable variable is set to ON.
The intake dampers operate based upon state, mode, and one of five user selected sequences. The dampers are normally open and operational in the occupied mode and closed to outside air in the unoccupied mode depending on the user selection. The five sequences are:
1. 100% OA, (Option GF2A)
When the unit is to start, the outside air damper will modulate (point Y1 = 10Vdc) and the supply fan will be commanded ON (point NO1 = On). If the unit is equipped with an outside air damper, the damper actuator is electrically interlocked to the fan start/stop such that the supply fan cannot start until the damper is 80% open. Air inlet configuration Options AR8, AR2D, AR2L, and AR2Y are electrically interlocked with the supply fan.
OFF and Alarm Modes
- The damper will be closed. Y1 = 0%.
2. External 0-10vdc Input, (Option GF1)
Occupied & Unoccupied Mode
The dampers will modulate from 0-100%. The control signal is sourced by others and a direct connection of a 0 to 10 vdc input to the unit terminal strip must be provided. This option is not allowed with air inlet configuration Options AR8,
AR2D, AR2L, and AR2Y. The software does not prevent the selection of this option. The fan status switch will handle the block flow condition. The damper is
NOT electrically interlocked with the supply fan.
Doc No D300535 (10-15), Page 8
3. Two-Position Dampers (Option GF2)
Occupied Mode
The damper will open to the user adjustable occupied damper position setpoint value (point Y1=10Vdc). For the damper options with only 100% outside air, the mechanical interlock of 80% will not allow the fan to start. Adjust the outside air setpoint to reach the minimum electrical interlock position.
Unoccupied Mode
With the unoccupied ventilation enable variable set to ON, the damper will open to the user adjustable unoccupied damper position setpoint value (point Y1=0Vdc).
For the damper options with only 100% outside air, the mechanical interlock of
80% will not allow the fan to start. Adjust the outside air setpoint to reach the minimum electrical interlock position. With the unoccupied ventilation enable variable set to OFF, the damper will be commanded to 0%.
OFF and Alarm Modes -
The damper will be closed. Y1 = 0%.
4. Four Positions based on 2 Digital Inputs (Option GF4)
Occupied Mode
The damper will open to the user adjustable defined position based upon two hardware input switches (ID9 & ID10).

3.6 Cooling Control
3.6.1 Cooling Control
Y3 (with the Option
CL78 th-tune device
ENABLED and
COMMUNICATING)
When the unit has a call for cooling from the th-tune device (Option CL78) in the space, it will use the unit U4 DAT input and Y3 to achieve the space cooling discharge air temperature setpoint. A call for space cooling takes priority over a call for space dehumidification.
A call for mechanical cooling Y3 will occur when the discharge air temperature is
5°F(2.8°C) above the active setpoint. When the OAT is above 65°F/18°C (Cooling
Lockout SP), the unit enables the mechanical cooling Y3 to maintain the active setpoint.
Cooling capacity/staging will follow a PI loop to maintain the active setpoint, Y3= 1-5V,
0-100% Capacity, Y3 = 1V is an OFF condition.
Space Cooling Active = Space dehumidification Y5 Reheat_Mod_Capacity Control not permitted.
Space Cooling Inactive = Space dehumidification Y5 Reheat_Mod_Capacity Control permitted.
If Space Cooling is inactive and the space humidity is above the space dehumidification setpoint, the unit will enter the space dehumidification mode. While in the space dehumidification mode, the Y3 compressor output will be enabled to maintain a
52
°F(11°C)
cooling coil discharge setpoint and will use the U5 CC_Temp sensor.
See dehumidification commands section for details on the operation of the reheat compressor Y5 output in space dehumidification mode.

3.6.2 Cooling Control
Y3 (with the Option
CL78 th-tune device
DISABLED and NOT
COMMUNICATING)
The unit will use the U4 DAT input and Y3 to achieve the neutral discharge air temperature setpoint.
A call for mechanical cooling will occur when the discharge air temperature is 5°F(2.8°C) above the neutral air setpoint. When the OAT is above 65°F/18°C (Cooling Lockout
SP), the unit enables the mechanical cooling Y3 to maintain the neutral air setpoint.
Cooling capacity/staging will follow a PI loop to maintain the active setpoint, Y3= 1-5V,
0-100% Capacity, Y3 = 1V is an OFF condition.
When the OA dewpoint is greater than 58°F(14°C) the unit will enter the neutral air dehumidification mode. While in the neutral air dehumidification mode, the Y3 compressor output will be enabled to maintain a 52
°F(11°C)
cooling coil discharge setpoint and will use the U5 CC_Temp sensor. See dehumidification commands section for details on the operation of the reheat compressor Y5 output in the neutral air dehumidification mode.

8.0 Communication
Cards
With the addition of an optional BMS Communication card, the building automation system can remotely adjust setpoints and view status points and alarms. The current supported building automation protocols are:
• BACnet
®
MSTP (Option BHB8)
• LonWorks
®
(Option BHB7)
Contact factory if additional protocol support is needed.
Communication Card
(Option BHB7 or BHB8)
8.1 BACnet
®
MSTP
(Option BHB8)
Communication
The BACnet
®
MSTP (Option BHB8) communication allows access to selected unit function parameters. The standard communication protocol is identified as BACnet
® over MS/TP (Master Slave / Token Passing). This protocol is used for communicating
BACnet
®
over a network of BACnet
®
only controllers. The network is considered open communication, whereas any device on the network has the capability to receive input from any other controller on the network. In all Y Series units included on a BACnet
® network, there are certain configuration parameters that need to be met before communication can be established with other devices. These settings and configuration parameters must be set properly or the device will not respond when prompted by other devices in the network. Follow the procedure below to modify the Bacnet MSTP parameters required by the BMS network.
1.
From the main menu navigate to E. Service and press the enter key to access the service menu.
2.
From the service menu navigate to the h. BMS Config submenu and press the enter key to select.
Press the enter key in succession until the cursor is flashing in the uppermost left hand corner of the screen and use the down arrow key to navigate to the next screen.
4.
From the BMS Config screen E.h.2 Press the enter key to access the Termconf PlugIn? Field and set the value to yes.
3.
From the BMS Config screen E.h.1 verify that the
Protocol: field is set to Bacnet MSTP. On a BAS card retrofit the Protocol: field may need to be set.
To change the protocol press the enter key until the cursor is flashing on the Protocol: field and use the up or down key to scroll through the available choices and select Bacnet MSTP then press enter to confirm the protocol change.
Press the enter key in succession until the cursor is flashing in the uppermost left hand corner of the screen and use the down arrow key to navigate to the next screen.

After saving the new setpoints, the controller must be power cycled to complete the process. Once the power has been restored and the bacnet card has initialized, return to the MSTP Setup screen E.h.4 to confirm the changes were accepted.
The BACnet
®
communication card has two sets of LEDs (Controller Status and
MSTP Status), a push button, and three jumpers.
The controller status LED
indicates the status of communication between the card and the controller. It is located above the push button.

Troubleshooting
Communication is not established and no data is passing to card. 1. Confirm card is firmly plugged in.
2. Confirm BMS Protocol is set to BACnet MSTP
The MSTP status LED
lights are located on the bottom side of the communication card below the controller status LED. The MSTP LED indicates the status of communication
between the card and the network
. Wait at least one minute after setting the communication parameters and plugging in the communication cable before determining the status of the network communication.
LED Lights (3 above) Description

Green and red both on
Communication with network is established and working.
Communication is not established and no data is passing to the card.

Troubleshooting
1. Confirm system and card baudrate are the same.
2. Confirm card Max Master is equal to or greater than the Station (MAC)
Address of the Master with the highest address.
The push button
on the communication card is used to return the card to factory configuration. Read and follow the procedure below to reset the card.
1. With controller OFF, depress and hold the push button located on the
BACnet board while powering the controller back ON.
Continue to hold the button, while watching the Status LEDs. Wait at least
20 seconds; the Status LED will flash SLOWLY 3 times, red-off.

2. Once the flashing begins, release the push button. After the 3 red flashes, the LED comes on green. The LED then confirms recognition of the button by flashing QUICKLY 3 times red-off, and then comes on green again.
3. Wait for about one minute for the factory parameters to be loaded.
The jumpers are used to create built in end-of-line resistance for a BACnet
®
MSTP network.
•
Jumper P1 adds a 510 ohm polarization resistance between the negative data line (-) and GND;
•
Jumper P2 adds a 120 ohm terminal resistance between the two data lines (+) and (-);
•
Jumper P3 adds a 510 ohm polarization resistance between the positive data line (+) and the +5 Vdc internal voltage.
Insert all three jumpers on the unit at the start of network and the unit at the end of the network. DO NOT insert the jumpers on the intermediate units.

8.2 LonWorks
®
(Option BHB7)
Communication
LonWorks
®
is an open protocol that was originally developed by Echelon Corporation. It is now maintained by Echelon in collaboration with members of the LonMark
®
Interoperability Association. It requires the use of Echelon’s Neuron microprocessor to encode and decode the LonWorks
®
packets.
The LonWorks
®
protocol is based on the concept of using standardized functional profiles to control similar pieces of equipment. The LonWorks
®
(Option BHB7) communication allows access to selected unit function parameters. The network is considered open communication, whereas any device on the network has the capability to receive input from any other controller on the network. In all Y Series units included on a Lon-
Works
®
network, the unit protocol configuration parameters must be set before communication can be established with other devices.
Follow the procedure below to set the BMS protocol to LonWorks
®
.
1.
From the main menu navigate to E. Service and press the enter key to access the service menu.
3.
From the BMS Config screen E.h.1 verify that the
Protocol: field is set to Lon. On a BAS card retrofit the Protocol: field may need to be set. To change the protocol press the enter key until the cursor is flashing on the Protocol: field and use the up or down key to scroll through the available choices and select Lon then press enter to confirm the protocol change.
2.
From the service menu navigate to the h. BMS Config submenu and press the enter key to select.
When complete press the escape key to return to the main menu.
The Lonworks communication card has the following components.
1. Serial port connection
2. Terminal block for LonWorks
®
network (GND, A, B)
3. Service pin
4. Service green LED
5. Anomaly red LED
To activate the service pin, simply short-circuit the two pins for an instant using the tip of a screwdriver or similar tool.
The activation is confirmed by the lighting of the service LED.
The service LED has several function listed below.
LED Light
Green
Description
1. Signals the status of the mode, as per the LonWorks protocol;
2. Remains ON during the activation of the service pin;
3. Remains ON for a second when receiving a WINK command from the network
Troubleshooting
The anomaly LED indicates the status of communication between the card and the controller.
LED Light
Off
Description
Communication with controller is established and working.
Troubleshooting
Red Communication is not established and no data is passing to the card.
1. Confirm card is firmly plugged in.
2. Confirm BMS Protocol is set to LON.
