ioDIGITALValve

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—upto 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-touchactivation.

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

•All ioDIGITAL valves include push-fitconnectors 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.

•Adjustingthemaximumtemperatureallowableis easily done on ioDIGITAL valves via a dial control. Such calibration of standard thermostatic cartridges is a more time-consumingprocess.

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 standardsASSE 1016 and

ASME A112.18.1M/CSA B125.1 (shower valves), and UL1951.

•All of the ioDIGITAL system components are backed by a five-yearlimited 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?

•TheMoenverticalspafeaturesfoursprayoutlets and a maximum flow rate of approximately 17.5 gpm at 45 psi flowing—configurationexamples 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-gallonor 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.

•WiththeMoenioDIGITALverticalspa,apressure of at least 40 psi is recommended for optimal performance and satisfaction.

6.Will the digital valves work with existing showerheads, hand showers and body sprays?

Yes, the ioDIGITAL system works with all Moen fixtures.

7.Will the valve fit within a regular 2" x 4" framed wall?

Yes.

8. Does the valve need to have ventilation?

No. The valve should be mounted in an interior wall to eliminate extreme temperature conditions. It should not be installed in locations that exceed the range of 40°F–104°F.

9.Do I have to plug the valve in, and is an electrician required for the installation?

Yes, the valve needs to be plugged into a 110v AC supply on a GFCI circuit. A certified electrician should install the initial GFCI outlet.

10.Is the valve compatible with PEX, copper and CPVC?

The push-fitconnectors supplied with ioDIGITAL

valves work well with each of these pipes— seals on the outside diameter.

11.Do you need an access panel for the valve?

•Yes. A minimum of 14-1/2"x 30" access panel is required.

•The valve must be installed with the front facing

the access panel.

12. Can the controller be installed outside the shower?

Yes. A 30-footdata cable connects the valve and controller, which gives you the ability to mount the controller at a convenient location within the home.

13.How does the controller mount to the wall?

The controller mounts simply with two screws in a standard 2" x 4" wall. Refer to instruction sheets INS1663 and INS1666.

14.What are the inlet sizes?

3/4".

15.What are the outlet sizes?

1/2".

16.Are water hammer arresters required?

Water hammer arresters are highly recommended, similar to other high- water-flowinghome appliances.

17.Are stops required?

Yes, stops upstream of the water hammer arresters to allow for servicing.

Note: Outlets A and B constitute

 

 

one valve body. Outlets C and D

A

B C D

constitute another valve body.

 

 

High-flowdevices (e.g., tub spouts,

 

 

multiple body sprays) should be split

 

 

up between the A/B and C/D outlet

 

 

pairs. For example, if a tub spout is

 

 

connected to outlet B, 3 body sprays

 

 

should connect to C or D, not A.

 

 

ExactTemp® 3/4" Thermostatic Control Moentrol® withBuilt-In3-FunctionTransfer Valve

The ExactTemp Thermostatic Control uses a mechanical system within the valve body to

­automatically adjust hot and cold water delivery and maintain consistent water temperature. The Moentrol valve lets users turn their spa on and off without changing the temperature position, so they can easily return to their last temperature setting.

Q:If the hot and cold inlets are mistakenly reversed, is the ExactTemp 3/4" cartridge reversible?

A:NO. Hot and cold inlets will have to be corrected­ for proper installation.

Q:Does the ExactTemp 3/4" cartridge need to be removed when soldering the valve?

A:NO. Neither the temperature nor flow cartridge needs to be removed. The cartridges will not overheat as a result of normal soldering process.

Q:Can components (body sprays, hand showers, etc.) be installed on a different wall than the transfer valve?

A:YES, but it is important to follow two basic principles­ to maximize performance: 1) minimize the distance between components and the transfer­ valve; 2) minimize the number of turns in the plumbing lines from the transfer valve to the component.

Q:Do I need to use 3/4" tubing between components?

A:It is recommended that you install 3/4" tubing between thermostatic and flow valves, and 1/2" pipe everywhere else. If 3/4" inlets are available,­ that is preferred. However, 1/2" will not diminish performance.
