Inputs/Outputs

Pump Connection
L This controller does not provide mains power to drive a pump­a pump must be driven via an external relay and contactor (pump start) setup
L The controller provides a low voltage signal that actuates the relay which in turn enables the contactor and finally the pump
® Although the controller has permanent memory and thus a default program will not cause erroneous valve actuation, it is good practice to connect unused zones on the unit back to the last used zone

® This in effect, inhibits the chances of the pump ever running against a closed head
L In some circumstances not all operational zones may be hooked up­for example, your KRX8 is capable of running 8 zones but there were only 4 field wires and solenoid valves available for connection
® This situation can pose a risk to a pump when the system test routine for the controller is initiated

28 of 40

Inputs/Outputs

Pump Connection

® In the above example this would mean zones 5 through to 8 would become active and would cause the pump to operate against a closed head
Á This could possibly cause permanent pump, pipe and pressure vessel damage

® It is mandatory if the system test routine is going to be used, that all unused, spare zones, should be linked together and then looped to the last working zone with a valve on it
® It is recommended to always use a relay between the controller and the pump starter for single phase pump installation

Additional Notes

Offline Device

® If your KRX8 still has a connection to power, it will still water the saved STARTS despite being offline from Holman Home­it will still be possible to water manually using the on-board controls

Additional Notes

Holman Home Automations
® STARTS run from a Holman Home automation will behave the same as a manually run START
® WATERING DELAYS only effect schedules from the KRX8 interface­ STARTS running from automations will ignore WATERING DELAYS
® To exclude ZONES using the WATERING DELAY function, this will need to be set using two automations­for example:
L If the time is 1:00 am and WATERING DELAY is ON, then water ZONE 1 and, if the time is 1:00 am and WATERING DELAY is OFF, then water ZONE 1, 2 and 3

Test Function
1. To test the KRX8 system, turn the MAIN DIAL to TEST
2. Press START on board the controller
® Activated ZONES in any START will run for 2 minutes, sequentially from ZONE 1 to 8
® If no ZONES are activated in any STARTS, the test function will not run
® To skip a ZONE during the process, press START on board the controller

Additional Notes

Wi-Fi Signal Strength

® Wi-Fi SIGNAL STRENGTH can be accessed on the DEVICE INFORMATION page­refer to DEVICE INFORMATION on how to access this

® This signal (c) determines if your internet connection is reliable enough for your KRX8 to function correctly

® The stronger the signal, the more reliable your connection will be

® The higher the number the

c

stronger the signal­for example;

a signal strength of -30 dBm

(decibel milliwatts) is considered

a perfect signal. A Wi-Fi

signal strength of -90 dBm

is considered not connected.

-60 dBm is considered the

minimum connection strength

Troubleshooting

Symptom
KRX8 cannot connect to Holman Home

Suggestion
When adding your KRX8 to Holman Home:
1. Confirm your KRX8 is powered ON
2. Confirm both your KRX8 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 KRX8 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 KRX8 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 KRX8. It is recommended that you replace the Wi-Fi router and try again

Troubleshooting

Symptom

Suggestion

KRX8 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 KRX8 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. Check and replace the fuse if necessary

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, blown fuse or power issue. If there are no lights on the controller check your fuse and then power point (refer to `Fuse keeps blowing’ below). If the unit works manually, check your program set up and dial position. The dial should be in the RUN position for regular use

Buttons not responding

Please contact our Customer Service team

Multiple zones watering at once

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

35 of 40

Troubleshooting

Symptom KRX8 is not connecting in AP MODE Rain sensor not working
Fuse keeps blowing

Suggestion
Ensure mobile data is switched off
For third party sensors, this could be faulty wiring or sensor. Check rain sensor information on Holman Home and check the wiring on sensor
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
