White-Rodgers Connect

The 50M56X-843 needs system components to be operational to configure the correct OEM connectors.  If one of these components is not functioning correctly, the control will show an E41 error.

Use the steps below to ensure these key components are in the correct state.

1. Review the warnings on the first page of the installation instructions.   This procedure should only be done by a qualified HVAC contractor or technician.
2. Disconnect electric power.
3. Ensure included universal replacement ignitor is installed.  Ignitor resistance when disconnected should be less than 100 ohms.
4. Use multimeter on ohms or continuity to confirm all limit switches and roll-out switches are closed.   You need to check them all individually, they may not be in a single continuous circuit on this control.
   • If switches are closed, proceed to step 5
   • If any switches are open, reset or replace safety switches that are open, apply power to unit and allow auto-configuration. If E41 persists, remove power and proceed to step 5
5. Check inducer and pressure switch per the following steps:
   • Disconnect wires from the inducer pressure switch.
   • Set multimeter to ohms or continuity, connect probes to pressure switch tabs. Keep them connected for the rest of the test.
     • If pressure switch is closed (<10 ohms), the pressure switch is causing the E41 error. 
   • Apply power to the system (control will displays dCF indicating automatic configuration is in process)
   • Inducer should turn on during start up configuration.
     • If inducer does not turn on before showing E41, this is the cause of the E41 Error. Verify inducer operates if powered directly. 
   • Confirm pressure switch closes with multimeter after inducer turns on.  
     • If pressure switch does not close when inducer turns on, the pressure switch is causing the E41 error.
   • When auto-configure completes, the control will show E41. This is ok during this test.
   • Remove multimeter from pressure switch and re-connect pressure switch to system wiring. 
   • Apply power to unit and allow auto-configuration procedure.

Other items to check: 

• Verify system wiring diagram matches the examples in the instructions.
• Confirm all wiring connections completed and secure prior to power up
• Verify Line (120V) and low voltage (24V XFMR) is in range and the on-board fuse is not open (E06)

Most smart phones manufactured after 2018 have NFC capabilities. You can check your settings to see if you have NFC.
Android

1. Open your phone’s settings
2. Open your connection settings (Wi-Fi, Bluetooth, etc.)
3. If you see a “NFC” section, then your phone is compatible.
   1. You can also check with your phone’s carrier for more information.

iOS
Most newer iPhones have NFC capability so that you can use the Apple Pay feature. 

• Your phone should be an iPhone 8 or newer.
• Using iOS 13.0 or later.

For Apple devices, the NFC antenna is typically located near the top edge on the back of the device.

For Android, the NFC antenna is typically located near the middle on the back of the device.

On the All-Spark Ignition Module, the NFC Antenna is in the middle of the control, indicated by the NFC marking on the cover label.

No. Please hold the device steady until the screen changes or the check mark appears.

In White-Rodgers Connect, there are three places for you to connect through NFC:

1. On the homepage, tap "Connect to Control"
2. In the Configuration tab, tab "Update Control"
3. In the Diagnostics tab, tap "Clear Error History"

Once any of these operations are tapped, place the NFC antenna of your device in contact with the NFC antenna of the control and keep your device in this location without moving until either a check mark appears or the screen changes on the App.

Most tablets do not have NFC capabilities. iPad tablets do not have an NFC antenna included on them.

Once the screen changes and the app confirms the NFC connection was successful, you can  pull your device away from the control to use the app. To complete another NFC connection,  you must place the device again in contact with the control.

First ensure you are using a compatible NFC device. You can check manufacturer specifications to determine if your device has NFC capability. 

If you are confident your device has NFC capability: 

• For Apple: Make sure of the following: 
  • There is no magnetic or metallic strip on the back of the device where the NFC antenna is located (remove your device cover first and then re-try). 
  • When trying to connect or update, the device is held in the proper location (see Question 4) without moving until the screen changes or the check mark appears.

• For Android: Make sure of the following: 
  • NFC is turned ON in settings.
  • Tap “Connect to Control” before the device has been placed in contact with the NFC antenna on the control.
  • There is no magnetic or metallic strip on the back of the device (remove your device cover first and then re-try).
  • When trying to connect or update, the device is held in the proper location (see Question 4) without moving until the screen changes or the check mark appears.

Only licensed HVAC contractors should use the White-Rodgers Connect App.

No. Users can only update the control they're currently scanning, and cannot copy updates to another control.

Please power on the control for at least 15 seconds and try again. 

Refer to the app listing for the latest OS requirements. Search you app store for "WR Connect".

You do not need an internet connection to search or update a control. 

You do need an internet connection to download the app or send an email regarding a connection issue or product suggestion.

No, the app does not require a login to use, and you will not create a username or password.

The auto-set feature works with hundreds of pre-loaded part numbers.
