Nero 2Relay
The NERO-2RELAY switches on and off two electrical loads up to 4A each. The outputs can be controlled separately or as a single virtual switch (software only).
The module can be controlled either through a Z-Wave Controller or through a wall switch.
The module measures the power consumption of the attached load and supports connection of a digital temperature sensor (available separately).
Nero Relay operates as a repeater in your mesh network, increasing reliability and range when combined with other Nero devices.
The NERO-2RELAY is not recommended or warranted for use with LED strip drivers. Please instead use the NERO-RELAY for strip lighting solutions.
Installation
RISK OF ELECTRICAL SHOCK! This device should only be installed by a qualified electrician and with appropriate precautions taken to ensure that power is not present during installation.
Even when the module is turned off, voltage may be present on its terminals. Any works on changes related to connection mode or load must always be performed with power disconnected.
- Before the installation, disconnect the power supply
- Connect the module according to electrical diagram
- Locate the antenna as far as possible from metal elements
- Do not shorten the antenna
- Nero Dual Relay requires an active and neutral for operation
Supported Switches
The module supports momentary switches (push button) and toggle switches. The module is factory set to operate with momentary switches. Momentary switches are recommended.
Overcurrent Protection Fuse
Nero Dual Relay must be installed with an over-current protection fuse not rated higher than 4A as illustrated in the wiring diagram.
