Based on UL 1026, 6th Ed. Rev. May 29, 2014, UL1026 has been ｕｐｄａｔｅd on Aug., 2015. These requirements related to wired or wireless remote commands were added. This requirement becomes effective right now.

Summary of ｕｐｄａｔｅ:

1. These requirements apply to wired or wireless remote commands from the user by way of:

• Controls only capable of communicating within line-of-sight of the appliance (e.g. infrared wireless);
• Short range controls only capable of communicating within proximity or same occupancy of the appliance but not necessarily within line-of-sight (e.g. short-wave radio frequency between 2.4 – 2.485 GHz); or
• Long range communication controls without proximity limits (e.g. WiFi, LAN, WAN).

2. Smart Enabled or Disabled

2.1The appliance shall include a means for the user to manually override any smart enabled power reduction, delayed start, remote operation commands, or modified operation.

The appliance shall include a means for the consumer to override any smart enabled or remote operation commands.

A flexible supply cord with an attachment plug can serve as the override means if the appliance:

• Is portable;
• Does not employ a motor rated more than 1/3 HP (250 W output);
• Does not have a switch or control with a marked OFF position;
• Is provided with instructions for unplugging the appliance to override smart enabled or remote functions.

2.2 A control on the appliance shall require manual adjusted setting before the appliance can be operated in a smart enabled or remote operation mode.

Examples for initiating this setting include, but are not limited to, pressing a button, pressing and holding a button, activating a switch or latch, set-up and connection to a local WiFi network, etc.

2.3 Once a smart or remote operation mode is enabled, it may remain in this state until mode of operation is manually disabled.

Exception No. 1: Not applicable to a control only capable of communicating to the appliance within line-of-sight.

Exception No. 2: Not applicable to appliances with remote functions limited to monitoring only.

2.4 An indicator that is visible during normal use shall be provided to indicate when the product is in smart enabled mode and can receive external communications or data.

3. Functional Safety

3.1 Controls actuated in response to external communication or data signals shall not introduce a hazardous operating condition or a state that may lead to a hazardous operating condition, the control:

a) Shall not render inoperative any protective control or protective control function within the appliance;

b) Shall not alter the response to or expected performance of user actuation of controls;

c) Shall not enable remote operation to allow starting or restarting of cooking mode function, or  functions involving hazardous exposed moving parts of the appliance, except as indicated in below for remote activation:

c.1) A remote activation is not permitted for operating modes considered “attended”, ｗｈｅｒｅ the user is intended to be present with the equipment during the entire cooking function, such as a toaster, grill, broiler, table stove, etc. ;

c.2) Remote operation is acceptable for other operations, considered “unattended”, such as a slow cooker, baking, convection, etc., under all of the following conditions：

1. The user can remotely initiate and set up for an unattended cooking mode. The Start button on the physical appliance must be pressed within 5 minutes of programming in order to initiate the cooking mode, otherwise it shall be cancelled. Remote programming may include remote activation for heating function modes and remote cancellation times only.
   Exception: The Start button is not required to be pressed within 5 minutes of programming of a slow cooker.
2. For appliances with a timer, such as a toaster oven, the duration of operation shall be set before the appliance can be started, unless the appliance switches off automatically at the end of a cycle or it can operate continuously without giving rise to a hazard.
3. Remote cancellation of any unattended cooking mode by the user is allowed.
4. Remote uploading of proprietary cooking algorithms by the user is allowed. However, reprogramming of any protective function is prohibited.

d) Remote uploading of proprietary cooking algorithms by the user is allowed. However, reprogramming of any protective function is prohibited.

e) Shall not automatically override the temperature setpoint beyond the value selected by the consumer.

f) Shall not alter the order of appliance control response (e.g. force a protective control to operate ｗｈｅｒｅ normally another control would respond, reset any protective manual reset temperature control or shutoff feature). or

g) Shall not supersede the response of any protective control.

3.2 Ovens, steam ovens, or toaster ovens shall comply with 3.1 and the following:

a) The ‘remote mode’ may only be set when the oven door is in the closed position. If the oven door is opened before the preheating/cooking mode is initiated, the selected remote operation shall be cancelled. The remote preheating/cooking mode may be programmed at the physical appliance or remotely.

b) If the oven door is opened before any remote function is started, a separate action from closing the door is necessary for the user to reinitiate the delayed start or remote operation cycle.

4. Communication and Display Devices

4.1 A communication or display device, such as a router or monitor, provided as an accessory for use with the appliance, shall comply with the Standard UL 60950-1.

4.2 The power supply cord of an external communication or display device shall comply with this standard or UL 60950-1, except Types NISP-2, NISPE-2, NISPT-2 are not allowed, but it is not applicable to which are located in low voltage circuits.
