Z-Wave Heatit ZM Dimmer 250W - 800 Series

A Compact In-Wall Dimmer for Z-Wave

Heatit ZM Dimmer turns an ordinary light switch into a smart dimmer. The small module fits in the back box behind your existing switch, so you keep the switches you already have while gaining full control from your Z-Wave controller, schedules and scenes. At just 46 × 21 × 45 mm it leaves plenty of room for wiring, and it works in both 2-wire and 3-wire installations.

Smooth, Flicker-Free Dimming

The dimmer handles up to 250 W of LED, incandescent and halogen lighting and is designed to work with most low loads without flickering, which is where many dimmers struggle with modern LED lamps. It calibrates its maximum level automatically, and the dimming range can be adjusted to suit the fittings you use, giving a smooth fade from bright to a soft glow.

Two Switch Inputs for Extra Control

Connect up to two external switches. Use one to control the lights directly, and the other to trigger scenes or control associated Z-Wave devices elsewhere in the home, so a single wall plate can switch the lights and set a whole-room mood. Associations also let it control other Z-Wave devices directly, without going through your controller.

Real-Time Power Metering

ZM Dimmer measures the power its lights use and reports it to your controller in real time, so you can see what each circuit is costing and spot lights that have been left on. Use the readings in automations, for example to turn lights off when nobody is in the room, or to track lighting energy use in your dashboard.

Built-In Protection

The module protects itself and your wiring against overload, short circuits, over-voltage and overheating, switching off safely if something goes wrong. Its screw terminals accept 0.2 to 2.5 mm² conductors, and firmware can be updated over the air so it keeps improving after installation. It is rated for indoor use between 5°C and 40°C.

Z-Wave 800 with S2 Security

Built on the Z-Wave 800 chipset, ZM Dimmer works with certified Z-Wave controllers such as Home Assistant, Hubitat and Homey Pro, and acts as a repeater to strengthen your mesh network. S2 security encrypts every command, and SmartStart makes inclusion quick: scan the QR code and it joins your network as soon as it is powered up.
