Troubleshooting

Symptom
KRX6 cannot connect to Holman Home

Suggestion
When adding your KRX6 to Holman Home:
1. Confirm your KRX6 is powered ON
2. Confirm both your KRX6 and smartphone are within Wi-Fi range
3. Ensure Bluetooth is turned on and permissions are approved for Holman Home
4. Make sure the network functions of your Wi-Fi router and smartphone are unblocked; firewalls can block certain ports
5. Confirm your Wi-Fi network name (SSID) has been entered correctly, including spaces. Note this is case sensitive
6. Confirm your Wi-Fi network password has been entered correctly
7. Confirm your KRX6 is connected to a 2.4GHz Wi-Fi network (not 5GHz), enable the broadcast and do not allow the Wi-Fi network to be hidden
8. Confirm your Wi-Fi router encryption method is WPA2-PSK and authentication type is AES, or both are set to automatic.
9. If the number of connected devices to the Wi-Fi has reached the amount limit (usually 16 or 50 devices), turn off other Wi-Fi devices and configure again
10. If your Wi-Fi router enables the MAC address filter, remove the device from MAC filter list and make sure the Wi-Fi router is allowing your KRX6 to be connected
11. Make sure that the Wi-Fi router has the DHCP service enabled. If it is not enabled, the address will be occupied.
12. Your Wi-Fi router may not compatible with your KRX6. It is recommended that you replace the Wi-Fi router and try again

Troubleshooting

Symptom

Suggestion

KRX6 was connected is now not connecting after mounting in desired position

This indicates a lack of Wi-Fi signal. You will need to move your KRX6 and Wi- Fi router closer to each other

No LED lights on

This indicates that there is no power to the unit. Your controller will not operate if there is an AC fault. Please check the power point or plug transformer pack for power. Using a multi meter is best for this action.
Replace the fuse.
If no power, there may be an issue with the controller. Plug pack transformers for the indoor models are available from Holman’s or your local electrical retailer. These require a 1amp 240 to 24V AC/AC transformer.

Single zone not working

Faulty solenoid coil, or break in field wire. Check solenoid coil (a good solenoid coil should read around 33 on a multi meter). Test field cable for continuity. Test common cable for continuity

No automatic start

Setup error, MAIN DIAL is in OFF position, or blown transformer. If unit works manually then check the setup or MAIN DIAL position. If not, check the fuse (next to the terminal block). If fuse doesn’t need replacing, then check the wiring and transformer is supplying 24V AC (measured on a multimeter)

Buttons not responding

Please contact our Customer Service team

Troubleshooting

Symptom
Multiple zones watering at once
KRX6 is not connecting in AP MODE
Fuse keeps blowing

Suggestion
Solenoids may be dirty: clean and flush solenoids to remove debris. Possible faulty driver triac, incorrect field wiring or broken or lost common wire in field. Check wiring and swap faulty valve wires on the controller terminal block with known working zones. If the same outputs are still locked on, please contact our Customer Service team
Ensure mobile data is switched off
The 1amp glass fuse is installed in the controller to protect the board from being damaged as a result of something wrong in the field wiring (this is the wiring from the solenoid to the controller).
If your fuse has blown, check that your wiring on each station is in tack and not damaged in any way. If your fuse is continuously blowing, remove all wires from your stations. Reconnect each station one at a time to help determine which station is causing the fault.
Our irrigation controllers use a 5mm x 20mm 1amp glass fuse
