WiCap fitting guide
Fitting WiCaps is a quick and easy process that does not require demounting of tyres or professional help. These are the steps:
i) Download the app.
ii) Pair the app with the WiCaps (so they can
communicate together) – achieved by fitting the WiCaps while the app is scanning for them.
iii) Set up the app so that it gives you alarms for over and under-inflation.
iv) Correct pressures (using the WiCaps).
v) Fit locknuts with the tool provided.
Here's the detail . . .
1. Download app Download, from the App page of this site, the iOS or Android app for your device. Just tap a button and the app will be installed in seconds on your device.
IMPORTANT PLEASE READ THE SAFETY GUIDANCE NOTES PROVIDED WITH THE WICAP KIT BEFORE PROCEEDING WITH FITTING
2. Understand the app main screen
The above illustration shows the start screen of the app which will appear when you first open the app on your phone or mobile device.
Although the app shows a car symbol, you can fit two or four WiCaps to a trailer, caravan, motorhome etc.
This screen is used to pair each WiCap with the app, via Bluetooth. Pairing allows the app to permanently and securely 'memorise' the IDs of the WiCaps so that they can communicate wirelessly together.
We've identified each dial with a number in the illustration above. Always match the numbers on the WiCaps with the respective dial number.
The dials represent wheel positions eg 1 = front left wheel.
If you have a kit of four caps, always start with 1 and continue in order.
If have a kit with two caps – if they are numbered 1 and 2, again start with 1. If you have a kit with caps numbered 3 and 4, start with 3.
Not following this order is the major cause of WiCaps not pairing. I'm sorry this aspect of the app makes a simple process seem so complicated!
Pairing is a ONE-TIME-ONLY process. You don't have to repeat the process if you remove a WiCap at any time.
3. Tap the first of the dials (top left of screen unless you have caps numbered 3 and 4 in which case you start with tapping dial 3).
The user guide with the WiCap kit explains this stage in more detail.The menu illustrated below will appear on your phone's screen.
4. Tap 'Auto-Bind' (iOS) or 'Auto-pair' (Android).
The start screen appears again. Tap the first dial
which now looks like this . . .
5. Tap dial (left top of screen – or bottom left if you have a kit with with WiCaps 3 and 4).
to initiate the pairing process for the first WiCap.
A countdown now appears . . .
6. Fit the WiCap
You now quickly and firmly fit the first WiCap to the first wheel. Doing this causes the WiCap to send a pairing signal to the app. Pairing is confirmed by the dial showing the WiCap's ID.
Repeat the process for the remaining one or three WiCaps. All this sounds complicated but actually takes seconds per wheel.
7. Tap the back arrow
– at the top left of the phone's screen – TWICE to see the tyre monitoring screen. This is now what you'll see every time you open the app.
Depending on how many WiCaps you've fitted you'll see tyre data on two or four dials.
Use the WiCaps to ensure your pressures are correct – as recommended by your vehicle manufacturer or tyre manufacturer. Do this pressure check when the vehicle has not been run for at least two hours and the tyres are 'cold'. The tyre industry defines 'cold' as 20°C.
8. Get the app settings as you want them
The settings screen, illustrated above, is reached from the main menu. It lets you select how you want the app to display tyre data and what under and over inflation alarms you need. This is explained, in more detail, in the user guide supplied with the WiCap kit.
8. Fit the lock nuts.
If you wish, you can fit the lock nuts supplied with the kit. They are meant to be a theft-deterrent – by tightening the nuts under the WiCaps so they 'lock' the Wicaps to the thread of the valve. Frankly, with a strong twist, the WiCaps can be removed without the use of a spanner. As a result, we think the lock nuts just make fitting and removing WiCaps that little bit of a hassle. Without them, it's much quicker to inflate the tyres when you need to. To repeat what was said earlier, you don't need to re-pair WiCaps when they are removed from the tyre valve. Pairing is a one-time process.
Changing the battery
A great money-saving feature of WiCaps is that batteries can be replaced (they last two to three years). In contrast, internal-fitting TPMS sensors generally need replacing – at considerable expense (generally, costing nearly as much as a kit of four WiCaps to replace just one internal sensor).
Here's how to change the WiCap battery:
Pull off the end cap, shown in the middle of the pic above. Then use the spanner that is provided in the kit to undo the centre part of the WiCap from its outer housing. The battery compartment is then revealed.
Hold the WiCap while carefully pushing out the battery with a tip of the spanner as shown. Underneath the battery is a paper insulator
– a disc with a hole in the centre. Push in the replacement CR1632 coin cell, noting that the surface with a plus (positive) is uppermost. Also ensure that the paper insulator remains in its original place (such that the centre terminal underneath the battery aligns with the hole in the centre of the insulator).
Screw the centre part of the WiCap back in to its outer housing. Use the spanner to tighten the two parts together. Then replace the end cap (on left in the pic above) so that the tab on it aligns with the slot in the outer casing. You may have to slightly tighten or loosen the centre part so that the tab aligns with the slot.
