ioDIGITAL™ Valve

ioDIGITAL uses a digital valve to control temperature and flow. This valve plugs into a standard 110v power outlet that can be located in a linen closet, under the tub—up to 30 feet from the bathroom — for easier installation and retrofit flexibility. The innovative design can also store up to 4 temperature and spray outlet flow combinations into memory with instant, one-touch activation.

1.Is a digital valve easier or more difficult to install compared to a regular thermostatic valve?

• All ioDIGITAL valves include push-fit connectors that work easily and quickly with traditional plumbing supply tubes (PEX, CPVC and copper).

• ioDIGITAL vertical spa systems require fewer trim components (handles/knobs) to install.

• Adjusting the maximum temperature allowable is easily done on ioDIGITAL valves via a dial control. Such calibration of standard thermostatic cartridges is a more time-consuming process.

2.How does the life expectancy of the digital valve compare with other thermostatic valves?

• The Moen ioDIGITAL system is certified to cUPC with applicable standards ASSE 1016 and ASME A112.18.1M/CSA B125.1 (shower valves), and UL1951.

• All of the ioDIGITAL system components are backed by a five-year limited warranty, and the finishes and mechanical components feature a Limited Lifetime Warranty.

3.How many spray outlets can be used in a digital vertical spa?

• The Moen vertical spa features four spray outlets and a maximum flow rate of approximately 17.5 gpm at 45 psi flowing—configuration examples to follow.

•Always cap unused outlets.

4.Do you need a larger hot water tank? What are the drainage requirements?

•The vertical spa will work with standard hot water tanks and typical drainage.

• If your shower layout includes two vertical spa ioDIGITAL spa valves, an 80-gallon or larger hot water tank is recommended. The vertical spa system works with plumbing and drainage that are common to most households.

5.What is the minimum water pressure needed for a digital valve?

• 20 psi, which is a code requirement.

• With the Moen ioDIGITAL vertical spa, a pressure of at least 40 psi is recommended for optimal performance and satisfaction.
