• Electronic controls are static sensitive devices. Discharge yourself properly before manipulating and installing the Terminal Equipment Controller.
• A short circuit or wrong wiring may permanently damage the Terminal Equipment Controller or the equipment.
• All SE7000 series Terminal Equipment Controllers are designed for use as operating controls only and are not safety devices. These instruments have undergone rigorous tests and verification prior
  to shipping to ensure proper and reliable operation in the field. Whenever a control failure could lead to personal injury and/or loss of property, it becomes the responsibility of the user / installer / electrical system designer to incorporate safety devices (such as relays, flow switch, thermal protections, etc…) and/or an alarm system to protect the entire system against such catastrophic failures. Tampering with the devices or unintended application of the devices will result in a void of warranty.

THEORY OF OPERATION

The SE7600 uses a Schneider-Electric proprietary adaptive logic algorithm to control the space temperature. This algorithm controls the heating and air conditioning system to minimize overshoot while still providing comfort. It provides exceptional accuracy due to its unique PI time proportioning control algorithm, which virtually eliminates temperature offset associated with traditional, differential-based On-Off Terminal Equipment Controllers.

Features overview

• 7 day schedule models, 2 or 4 events
• Gas, oil or electric system compatibility for all type of applications
• Remote indoor averaging sensing capability
• Temperature averaging with 2, 3, 4, 9 or 16 sensors
• Remote outdoor sensing capability for added flexibility
• System mode lock out
• Heat pump balance point settings
• Remote discharge air sensor input for monitoring purpose
• System efficiency feedback
• Lockable keypads for tamper proofing. No need for Terminal Equipment Controller guards
• Automatic frost protection to prevents costly freeze damage
• Anti short cycle and minimum On-Off run time protection.
  Reduces wear and maximizes life span of mechanical equipment.
• 2 configurable digital inputs for added flexibility. Each input can be configured as the following:
  • None: No function will be associated with the input
  • Service: a backlit flashing Service alarm will be displayed on the Terminal Equipment Controller LCD screen when the input is energized. It can be tied in to the AC unit control card, which provides an alarm in case of malfunction.
  • Filter: a backlit flashing Filter alarm will be displayed on the Terminal Equipment Controller LCD screen when the input is energized. It can be tied to a differential pressure switch
    that monitor filters.
  • Rem NSB: remote NSB timer clock input. Will disable the internal scheduling of the Terminal Equipment Controller.
    The scheduling will now be set as per the digital input. The menu part related to scheduling is disabled and no longer accessible. It provides low cost setback operation via occupancy sensor or from a dry contact.
  • RemOVR: temporary occupancy contact. Disables all override menu function of the Terminal Equipment Controller.The override function is now controlled by a manual remote momentarily closed contact. When configured in this mode, the input operates in a toggle mode.
    With this function enabled it is now possible to toggle between unoccupied & occupied setpoints for the amount of time set by parameter (TOccTime) temporary occupancy time.
  • Fan lock: used in conjunction with a local air flow sensor connected to the input. Locks out the Terminal Equipment Controller heating and cooling action and displays a local alarm if no air flow is detected 10 seconds after the fan (G terminal) is energized.
• Configurable smart fan operation saves energy during night mode
• Non volatile EEPROM memory prevents loss of parameters during power shortage
• Built in default profile set-up for easier start up and commissioning
• Configurable SPST output relay on Scheduling models for lighting, exhaust fan or fresh air control
• 6 hour typical reserve time for clock in case of power loss
• 0 to 10 VDC economizer output for more retrofit opportunities
• Built in dry bulb economizer logic using outdoor temperature sensor
• Input for supply or mixed air temperature sensor.

Heat pump model-specific features

• Selectable single or dual stage compressor stages
• High balance point:
• Locks out auxiliary heating when outside air temperature is above this value
• Low balance point:
• Locks out heat pump compressor operation when outside air temperature is below this value
• Comfort or economy mode:
• In economy mode, heat pump use is maximized before turning On auxiliary heating
• Compressor or auxiliary interlock:
• Adds flexibility by locking out heat pump operation during auxiliary heating to prevent high pressure trip when the coil is downstream of the auxiliary heat source.

There is a default profile set in the Terminal Equipment Controller from the factory.

This enables the Terminal Equipment Controller to operate as a non-scheduling unit in day mode operation at start up.

DEFAULT TEMPERATURE SETPOINTS:		DEFAULT MODES:
Occupied cooling setpoint = 24 °C (75 °F)		System mode = Auto
Occupied heating setpoint = 22 °C (72 °F)		Fan mode = Smart (for models with a communication module or scheduling network-ready models) Fan mode = Auto (for non-scheduling network ready models)
Unoccupied cooling setpoint = 28 °C (82°F)
Unoccupied heating setpoint = 18 °C (65°F)		DEFAULT SCHEDULES:
Fahrenheit scale		Monday through Sunday
Setpoint type = permanent		Occupied time is: 12 00 AM
		Unoccupied time is: 11:59 PM

There will be a 1 minute unoccupied period every night at 11:59 PM with this default configuration.

A) Override an unoccupied period

• Override
• schd Y/N

This menu will appear only when the Terminal Equipment Controller is in unoccupied mode. The unoccupied mode is enabled either by the internal timer scheduling or by a remote NSB contact via DI1 or DI2.
If DI1 or DI2 is configured to operate as a remote temporary override contact, this menu will be disabled.
Answering yes to this prompt will cause the Terminal Equipment Controller to go into occupied mode for an amount of time equal to the parameter “TOccTime” (1 to 12 hours).

B) Resume regular scheduling

• Cancel
• ovrd Y/N

This menu does not appear in regular operation. It will appear only when the Terminal Equipment Controller is in Unoccupied override mode.

	Occupied		Unoccupied		Occupied		Unoccupied
Setpoint	Cool 72 °F	Heat 70 °F	Cool 80 °F	Heat 62 °F	Cool 72 °F	Heat 70 °F	Cool 80 °F	Heat 62 °F	Daily Occupancy
Monday	7.00 AM		5.00 PM		12.00 PM *		12.00 PM *		Day time only
Tuesday	7.00 AM		5.00 PM		12.00 PM *		12.00 PM *		Day time only
Wednesday	7.00 AM		5.00 PM		12.00 PM *		12.00 PM *		Day time only
Thursday	7.00 AM		5.00 PM		7.00 PM		10.30 PM		Day/evening time only
Friday	7.00 AM		5.00 PM		7.00 PM		10.30 PM		Day/evening time only
Saturday	12.00 PM *		12.00 PM *		12.00 PM *		12.00 PM *		Occupied
Sunday	12.00 PM *		12.00 PM *		12.00 PM *		12.00 PM *		Occupied

Programming events to the same time will cancel the last period and leave the thermostat in unoccupied mode

Ex. #2 Residential

Event	Period #1 – Event #1		Period #1 – Event #2		Period #2 – Event #3		Period #2 – Event #4
	Occupied		Unoccupied		Occupied		Unoccupied
Setpoint	Cool 72 °F	Heat 70 °F	Cool 80 °F	Heat 62 °F	Cool 72 °F	Heat 70 °F	Cool 80 °F	Heat 62 °F	Daily Occupancy
Monday	6:00 AM		8:00 AM		4:00 PM		10:00 PM		Day/evening time only
Tuesday	6:00 AM		8:00 AM		4:00 PM		10:00 PM		Day/evening time only
Wednesday	6:00 AM		8:00 AM		4:00 PM		10:00 PM		Day/evening time only
Thursday	6:00 AM		8:00 AM		4:00 PM		10:00 PM		Day/evening time only
Friday	6:00 AM		8:00 AM		4:00 PM		11:30 PM		Day/evening time only
Saturday	8:00 AM **		8:00 AM **		8:00 AM **		11:59 PM **		Day time only
Sunday	12:00 AM **		12:00 AM **		12:00 AM **		11:59 PM **		Occupied all day

Programming consecutive events to the same time will cause the thermostat to choose the last event as the time at which it will set its schedule.
In the above example for Saturday, the thermostat will control to the occupied set point from 8:00 AM until 11:59 PM. Since it is desired to be in occupied mode throughout the night, then it is necessary to program the first event on Sunday at 12:00 AM. The thermostat will force a one minute unoccupied period for a one minute period (between 11:59 PM and 12:00 AM on Saturday).

• This section of the menu permits the user to set a permanent schedule hold, which bypasses the internal Terminal Equipment Controller scheduling.
• The permanent schedule hold function is typically used for nonscheduled events that extend for various periods of time.
• Enabling a permanent occupied or permanent unoccupied schedule hold will cancel any active override.
• The use of temporary setpoints during permanent hold is permitted. The duration of the temporary setpoint is as set per the TOccTime parameter.
• Ex. 3 hours
  Use ▲▼ to set value, yes key to confirm

Schedule resume	Resume regular scheduling cancels the permanent hold and re-enables the regular scheduling as set per internal schedule or as per remote NSB via one of the DI’s configured as remote NSB. This action can also by accomplished by using the Resume menu. Any temporary setpoint that are active will be left active for the duration of the period as set per the TOccTime parameter.
Schedule occ hold	Hold permanent occupied forces the Terminal Equipment Controller into a permanent occupied mode using the occupied setpoints. All timed scheduling functions are by-passed. The PERMANENT OCCUPIED status will appear in the automatic status scroll. To resume to regular scheduling, user must scroll to the Schedule Hold menu and select the Schedule resume option.
Schedule uno hold	Hold permanent unoccupied forces the Terminal Equipment Controller into a permanent unoccupied mode using the unoccupied setpoints. All timed scheduling functions are by-passed. The PERMANENT UNOCCUPIED status will appear in the automatic status scroll. To resume to regular scheduling, user must scroll to the Schedule Hold menu and select the Schedule resume option.

If the Terminal Equipment Controller is installed as a stand-alone (Network Ready) unit or with an Echelon® adapter, this parameter will not be used or displayed For BACnet® MS-TP models, the valid range to is from 1 to 127. Default value of 254 disables BACnet® communication for the Terminal Equipment Controller. For wireless models valid range is 0 to 254 with a maximum of 30 Terminal Equipment Controllers per VWG
PAN ID Personal Area Network Identification Default value = 0 Range is: 0 to 500	Conditional parameter to Wireless models SE76xxX5x45W This parameter will only appear when a wireless network adapter is present. If the Terminal Equipment Controller is installed as a stand-alone (Network Ready) unit or with a BACnet® or Echelon® adapter, this parameter will not be used or displayed. This parameter (Personal Area Network Identification) is used to link specific Terminal Equipment Control- lers to a single specific Schneider-Electric wireless gateway (VWG). For every Terminal Equipment Control- ler reporting to a gateway (maximum of 30 Terminal Equipment Controllers per gateway), be sure you set the SAME PAN ID value both on the gateway and the Terminal Equipment Controller(s). The default value of 0 is NOT a valid PAN ID. The valid range of available PAN ID is from 1 to 500.
Channel Channel selection Default value = 10 Range is: 10 to 26	Conditional parameter to Wireless models SE76xxX5x45W This parameter will only appear when a wireless network adapter is present. If the Terminal Equipment Controller is installed as a stand-alone (Network Ready) unit or with a BACnet® or Echelon® adapter, this parameter will not be used or displayed. This parameter (Channel) is used to link specific Terminal Equipment Terminal Equipment Controllers to specific Schneider-Electric wireless gateway(s) (VWG). For every Terminal Equipment Terminal Equipment Controller reporting to a gateway (maximum of 30 Terminal Equipment Controllers per gateway), be sure you set the SAME channel value both on the gateway and the Terminal Equipment Controller(s). Schneider-Electric recommends using only channels 15 and 25. The default value of 10 is NOT a valid channel. The valid range of available channel is from 11 to 26

Get From Terminal Equipment Controller Get From another device configuration utility Default value = 0 Range is: 0 to 254	Conditional parameter to Wireless models SE76xxX5x45W Entering a MAC address enables an automatic routine that automatically fetches all the required configura- tion properties of the current device from another already configured device and copies the same required configured property values. If a value other than the default value of 255 is entered, user will then be prompted to exit the Configuration Menu thus leaving all other parameter configuration to be copied from the referenced Terminal Equipment Controller MAC address. Ex.: If you are currently configuring MAC12 and the settings matches exactly the settings of ZN MAC5, then enter 5 as the current parameter value. If the process is successful and all required configuration properties have been copied, the value will revert back to 255 If the process is NOT successful and all required configuration properties have NOT been copied ( either the reference device is NOT the same model number or is offline or does not exists ) the value will revert back to 254 to indicate the failure of the process Leaving the Get From parameter to 255 means that every configuration parameters will be set manually.

The Terminal Equipment Controller will automatically optimize the equipment start time. In any case, the latest a system will restart is 10 minutes prior to the occupied period time.

Heat Pump models only
High bp High balance point Default value = 90 °F (32.0 °C) Function will only be enabled if OS (outside air temperature sensor) is connected.	In Heating or Auto mode, it is the outside air temperature value at which the auxiliary heat will be cut off. Above that value, only the heat pump will be used to maintain the heating setpoint 34 to 90 °F (1.0 to 32.0 °C)
Low bp Low balance point Default value = -12 °F (-24 °C) Function will only be enabled if OS (outside air temperature sensor) is connected.	In Heating, Cooling or Auto mode, it is the outside air temperature value at which the heat pump operation will be cut off. Below that value, only the auxiliary heat will be used to maintain the heating setpoint -40 to 30 °F (-40 to -1.0 °C)
Comf/eco Comfort or economy mode Default value = Comfort	Sets the operation and interaction mode of the heat pump with the auxiliary heat. Comfort mode. In Heating mode. If the heat pump is not able to satisfy the heating setpoint, the auxiliary heat will be energized to satisfy the same heating setpoint. Economy mode. In Heating mode. If the heat pump is not able to satisfy the heating setpoint, the auxiliary heat will be energized to satisfy only when the temperature has dropped 2.0 °F ( 1.1 °C ) below the heating setpoint. Selecting economy mode will add a deadband between the heatpump & auxiliary heat in heating mode. The actual temperature main- tained will be lower than the true heating setpoint to maximize the heat pump operation. When the outdoor air temperature drops below the low balance point, the deadband will be eliminated and the auxiliary heat will maintain the true heating setpoint alone. Economy mode. In Emergency mode. If Emergency heat mode is selected, the setpoint maintained, will be the heating setpoint.
Re valve Reversing valve operation O/B Default value = O	Heat pump reversing valve operation O will energize the valve in cooling operation. B will energize the valve in heating operation O OR B
Comp/aux Compressor/auxiliary interlock Default value = Off	Sets the operation and interaction mode of the heat pump with the auxiliary heat. Interlock Off. In Heating mode. If the heat pump is not able to satisfy the heating setpoint, the auxiliary heat will be energized at the same time as the heat pump stage. Typically applies when the air handler heat pump coil is installed before the auxiliary heat (all electric systems). Interlock On. In Heating mode. If the heat pump is not able to satisfy the heating setpoint, the auxiliary heat will be energized and the heat pump will be cut off. Typically applies when the air handler heat pump coil is installed after the auxiliary heat (add on systems). There is a 2 minute delay to restart the heat pump, when the auxiliary heat is shut down Off or On
Notes for Heat Pump models: When the outside air sensor is not connected or is shorted, the Terminal Equipment Controller bypasses the heating / cooling lockouts and the low / high balance points. Also Heat Pump model when set in Emergency system mode bypasses heating lockout and permits auxiliary heating whenever a heating demand occurs.

chngstpt Changeover setpoint Default value = 55 °F (13.0 °C)	In Cooling mode. The outside air temperature value at which the cooling will be switched over from mechanical ( compressor ) to free cooling (economizer) 14 to 70 °F ( -10.0 to 21.0 °C )
