Load Types (relay ratings)
-
Rated to control 120-277 V~ 20 A receptacles with any output.
-
When using the Energi Savr Node to control receptacles, it may be used with, but is not limited to, the following:
– Monitors
– Fans
– Humidifiers
– Printers
Note: Refer to the manufacturer’s guidelines for acceptable switching methods. -
When using the Energi Savr Node to control receptacles, it may NOT be suitable for use with devices that require any of the following:
– Shut-down process before power is interrupted, such as computers.
– Cool-down process before power is interrupted, such as projectors.
– Programming, such as clocks or DVRs.
– Long warm-up cycle. -
Not for use with loads that present a hazard if automatically energized (e.g., heaters).
-
Any receptacles that are controlled by an automatic control device must be marked with “ Controlled” located on the controlled receptacle outlet where visible after installation as stated in 2017 NEC® Article 406.3(E).
Softswitch 120–277 V~; 347 V~
- For Softswitch relay ratings see the Relay Ratings chart under Load Types section.
- Relay is mechanically held.
0–10 V Output Ratings (QSN2-4T20-S, QSN2-4T16-S-347)
- Each output sinks up to 50 mA maximum.
- Each output sinks current only (load device must provide 10 V supply).
- Provides an IEC PELV/NEC® Class 2 isolated 0–10 V output signal that conforms to IEC 60929.
- 0–10 V fixtures must support switching power to turn on/off. Use switched outputs to switch fixtures according to wiring diagrams shown on pages 9-11
- Minimum voltage (Off, when relay is open) at the 0–10 V terminals of the ESN module is 1.0 V when 0–10 V wires are loaded to 50 mA. Voltage at the fixture will vary; refer to “How far can I run a low voltage 0–10 V circuit” of App Note #587 (P/N 048597) at www.lutron.com to determine required wire gauges, lengths, and compatibility.
Contact Closure Input (CCI)
- Activate scenes using momentary or maintained closures from an external device such as a timeclock.
- The attached device must provide a dry-contact closure or solid-state output.
- Configurable for normally-open (NO) or normally-closed (NC) operation.
- Input is miswire-protected up to 36 V .
Emergency Contact Closure Input
- By default, contact closure input from Lutron Emergency Lighting Interface (LUT-ELI-3PH), security, or fire alarm systems turns all zones on to full output when emergency state is detected.
- Emergency contact closure input is normally closed (NC). The ESN unit is shipped with a jumper pre-installed.
- Response of each zone is configurable.
- Attached devices, by default, will go to maximum output and ignore control inputs.
- No operations will be allowed until emergency signal is cleared.
- The attached device must provide a dry-contact closure or solid-state output.
- Input is miswire-protected up to 36 V .
- Emergency CCI cannot control other ESN units.
QS Link Limits
- ESN unit does not provide PDUs
- Each ESN unit counts as 1 device towards the QS device limit.
- Each ESN unit counts as 4 zones towards the zone limit.
Programming and Compatibility Requirements
- Setup and programming of the switching power module is done through the Athena programming software.
- Athena software version 20.4 or higher is required.
Out of Box Functionality
This section describes the default functionality when the unit is first installed.
Emergency Contact Closure Input (CCI)
- Normal mode: The unit can dim loads as normal and respond to button presses, occupancy sensors, daylight sensors, timeclock events and preset scene calls.
- Emergency mode: When the Emergency CCI is open, the unit will override the light output to its emergency level and enter lockout mode. It will not respond to any button presses, occupancy sensors, daylight sensors, timeclock events, or preset scene calls.
- Return from Emergency mode to Normal mode: Once the Emergency CCI is closed or jumpered, the zones will return to the previous light level and it will again respond to button presses, occupancy sensors, daylight sensors, timeclock events, and preset scene calls.
Note: Unit will process any sensor events received while in emergency mode after it exits emergency mode.
Contact Closure Input (CCI)
- Momentary closure from a normally-open (NO) dry-contact closure device will result in all zones being turned off.
Normal Mode Operation
- In normal operation, the following buttons allow the user to access certain basic functions:
- Raise
- 0-10 V /Softswitch: Raises zone light level in 1% increments from 0-100%.
- Softswitch: Turns selected zone on.
- Lower
- o 0-10 V /Softswitch: Decreases zone light level in 1% decrements from 100-0%.
- Softswitch: Turns selected zone off.
Note: On 0-10 V /Softswitch only — For any zone, simultaneously pressing and holding the Raise and Lower buttons will toggle the zone between high-end and low-end.
Mechanical Dimensions
All dimensions shown as in (mm)
Wiring: QS Link

- Follow all national and local codes for separation requirements.
- If any pair of 0-10 V control wires are installed using NECR Class 1 wiring methods, then these wires must be physically separated from all other Class 2 wiring in the Energi Savr Node in accordance with NECR guidance on separation of Class 1 and 2 wires.
- If one pair of 0-10 V control wires are wired using NECR Class 1 wiring methods, then all pairs of 0-10 V- control wires must be installed using NECR Class 1 wiring methods.
WARNING: Entrapment/Fire Hazard. To avoid the risk of entrapment, serious injury, or death, these controls must not be used to control equipment which is not visible from every control location or which could create hazardous situations such as entrapment if operated accidentally. Examples of such equipment which must not be operated by these controls include (but are not limited to) motorized gates, industrial doors, space heaters, etc. It is the installer’s responsibility to ensure that the equipment being controlled is visible from every control location and that only suitable equipment is connected to these controls. Failure to do so could result in serious injury or death.
