The Ajax WallSwitch is a wireless, remote control power relay with an energy monitor used for controlling 220v appliances such as lights, aircons, borehole and pool pumps etc not exceeding 3kW.

The relay power supply is not galvanically isolated with terminal blocks; therefore, the Ajax WallSwitch switches only the power received at the power supply terminal blocks. The device has an energy consumption meter and features three types of protection: voltage, current, and temperature.

The WallSwitch can be controlled manually via the Ajax app, Button press or by Scenario.

Ajax WallSwitch operating principle

The Ajax WallSwitch is a power relay of the Ajax system. The relay is installed in the electrical circuit gap to control the power supply of devices connected to this circuit. The relay can be controlled via the function button on the device (by holding it down for 2 seconds), the Ajax app, Button, and automation scenarios.

The Ajax WallSwitch switches one single pole of the electrical circuit — the phase. In this case, the neutral is not commuted and remains closed.
The Ajax WallSwitch measures the current, voltage, the amount of energy consumed by electrical appliances, and the power they consume. This data, along with other operating parameters of the relay, is available in the device States.

Scenario types with Ajax WallSwitch and examples of usage:

By alarm. Lighting is switched on when an opening detector raises the alarm.
By security mode change. The electric lock is automatically blocked when the object is armed.
By schedule. The irrigation system in the yard is switched on according to the schedule for the specified time. Lighting and TV are switched on when the owners are away so the house doesn’t seem empty.
By pressing Button. Switching on night lighting by pressing the smart button.
By temperature. The heating is turned on when the temperature in the room is lower than 20°C.
By humidity. The humidifier is switched on when the humidity level drops below 40%.
By CO₂ concentration. Supply ventilation is turned on when the carbon dioxide concentration level exceeds 1000 ppm.

Control via the app

In Ajax apps, a user can switch on and off electrical appliances connected to an electrical circuit controlled by WallSwitch.

Click the toggle in the Ajax WallSwitch field in the Devices menu: the state of the relay contacts will change to the opposite, and the connected electrical device will switch off or on. This way, a security system user can remotely control the power supply, for example, for a heater or a humidifier.
Energy consumption monitoring
In the Ajax app, the following energy consumption parameters are available for appliances connected via WallSwitch:

• Voltage.
• Load current.
• Power consumption.
• Power consumed.

Update frequency of parameters depends on Jeweller or Jeweller/Fibra polling period (default value is 36 seconds). Power consumption values are not reset in the app. To reset the readings, temporarily power off WallSwitch.
