Cold Load Pickup
EnergyWise Business Wi-Fi switch is designed to prevent the connected load from coming back on immediately after a
®
power outage. This ensures that the electrical grid has time to recover from the transient condition that caused the outage.
When the Cold Load Pickup is activated, the Relay LEDs will turn on and the relays are open to prevent the load from running.
This is normal. After the Cold Load Pickup timer expires, the connected appliance is allowed to resume its normal operation.
The default Cold Load Pickup time delay is:
• HVAC – 90 seconds
Hardware Error Reporting
If the EnergyWise Business Wi-Fi switch hardware senses an error that prevents normal operation of the switch, then all
LEDs will flash as an indicator of this condition. If this happens repeatedly, then the switch should be replaced.
