Zooz ZAC36 LR Titan Water Valve Actuator

Devices are typically rated using the Ingress Protection (IP) scale, which indicates the level of protection against dust, solid particles, and moisture.

An IP rating (Ingress Protection rating) is a standardized way to describe how well a device is protected against solids (like dust) and liquids (like water). The rating consists of two digits:

- The first digit represents protection against solid particles (e.g., dust).

- The second digit represents protection against liquids (e.g., water).

First Digit (Protection Against Solids):

- IP0X: No protection against solid objects.

- IP1X: Protection against solid objects larger than 50 mm (e.g., accidental touch by hand).

- IP2X: Protection against objects larger than 12.5 mm (e.g., fingers).

- IP3X: Protection against objects larger than 2.5 mm (e.g., tools or thick wires).

- IP4X: Protection against objects larger than 1 mm (e.g., thin wires or small tools).

- IP5X: Dust-protected. Limited ingress of dust is allowed, but it won't interfere with operation.

- IP6X: Dust-tight. Complete protection against dust, ensuring no ingress of particles.

Second Digit (Protection Against Liquids)

- IPX0: No protection against water.

- IPX1: Protection against vertically falling water droplets (e.g., light rain).

- IPX2: Protection against vertically dripping water when tilted up to 15°.

- IPX3: Protection against water sprayed at an angle of up to 60° (e.g., light splashing).

- IPX4: Protection against water splashes from any direction.

- IPX5: Protection against water jets from any direction (e.g., a garden hose).

- IPX6: Protection against powerful water jets (e.g., heavy rain or washing with a hose).

- IPX7: Protection against temporary immersion in water up to 1 meter deep for up to 30 minutes.

- IPX8: Protection against continuous immersion in water beyond 1 meter.

Length x Width x Height

- Length: the longest side of the device

- Width: the shorter side of the device

- Height: the vertical dimension of the device

The physical weight of the device, typically measured in grams (g) or ounces (oz).

Weight can be important for installation considerations, especially for wall-mounted or battery-powered devices.

Powered from a wall outlet through an AC adapter, so the valve never runs out of battery.

A plug-in valve needs an outlet within reach of the main line, and it stops working during a power outage unless it also has a battery backup.

The batteries a battery-powered valve runs on. Most retrofit actuators use standard AA cells, while some meters use a long-life lithium pack.

Standard AA batteries are cheap and easy to replace; a sealed lithium pack lasts longer but has to be bought from the manufacturer.

How long the manufacturer says the batteries last under normal use, typically measured in months or years.

Turning a stiff valve takes a lot of energy, so battery life depends on how often the valve is closed, exercised or tested.

A battery that keeps a plug-in valve working when the power goes out, either built in or sold as an optional module.

Storms that cut the power are also when pipes freeze and sump pumps fail, so a valve that keeps working on battery protects the house exactly when it is most at risk. Battery-only valves do not need one.

Range: The 2.4 GHz band offers a longer range, meaning it can cover larger areas and penetrate solid objects like walls more effectively than 5 GHz.

Speed: Generally, 2.4 GHz provides slower speeds compared to 5 GHz due to a lower maximum data rate.

Interference: More prone to interference since many other devices (like cordless phones, microwaves, and Bluetooth devices) operate on the 2.4 GHz frequency, leading to potential congestion and slower network performance.

How the device controls the water. A retrofit actuator is a motor that clamps onto the handle of the shutoff valve you already have and turns it, so it installs in minutes with no plumbing work.

An inline valve is a motorized valve that is cut into the main water line, usually by a plumber. It costs more to install, but it often carries a flow sensor that lets it detect leaks on its own, and some insurers only recognize this type.

For a retrofit actuator, the range of shutoff valve sizes its bracket can mount on. For an inline valve, the pipe sizes the valve is sold in.

Most homes have a 3/4 inch or 1 inch main line. Measure your pipe before buying, because a valve that does not fit cannot be installed.

The turning force of the motor, usually given in newton meters (N·m).

Old shutoff valves that have not been turned in years can be very stiff. A retrofit actuator with more torque is more likely to close them reliably, which matters most in an emergency.

The valve turns itself partway on a schedule (for example once a month) and back, to keep it from seizing.

A shutoff valve that sits open for years can build up mineral deposits and stick, and a stuck valve is the most common reason an automatic shutoff fails when it is finally needed.

A built-in sensor that measures how much water is flowing through the main line.

With a flow sensor the valve can detect a leak on its own (a burst pipe, a running toilet, water flowing for longer than normal) and close without waiting for a leak sensor to get wet. It is also what shows your water usage in the app.

A test the valve runs on its own, usually at night: it closes briefly and watches the water pressure for any drop.

A falling pressure with the valve closed means water is escaping somewhere, which finds slow leaks of a few drops per minute that flow sensing alone misses.

The valve closes automatically when a leak is detected even if the internet is down, because it talks to its leak sensors directly or through a local hub instead of through the cloud.

Leaks do not wait for a working connection. A valve that depends on a cloud service to receive the alarm from a leak sensor will not close during an internet outage.

The valve includes or accepts a leak sensor connected to it by a cable, usually a probe or a sensing cable placed on the floor next to the water heater or the main line.

A wired sensor closes the valve directly, with no wireless link, hub or battery in between, which makes it the most reliable trigger for the spot right next to the valve.

Notifications when the temperature at the valve or of the water drops close to freezing.

Frozen pipes are one of the most common causes of burst pipes in winter, and an early warning gives you time to add heat or shut off the water before a pipe cracks.

The ability to open or close the valve automatically based on other devices or schedules, such as closing the water when a leak sensor gets wet or when everyone leaves on vacation.

Automations are what turn a remote-controlled valve into automatic flood protection.
