An illustrative diagram showing how to connect main power (L, N), underfloor heating manifold (230V to pump, 1.5mm² cable), optional boiler connection, and a dew point sensor to the KL08RF wiring centre. It also indicates connections for various thermostat types (G1/G2) and zone actuators.
Wiring Steps:
- Power Supply: Connect the main 230V AC power supply to the L and N terminals marked 'Power'.
- Zone Actuators: Connect the thermal actuators for each heating zone to the corresponding numbered terminals (1-8). Each zone typically requires two wires.
- Pump: Connect the underfloor heating pump to the terminals marked 'Pump'.
- Boiler: Connect the boiler control wires to the terminals marked 'Boiler'. This connection typically signals the boiler to fire when heat is required.
- Dew Point Sensor (Optional): If using, connect the dew point sensor to the designated terminals. This sensor helps prevent condensation in cooling applications.
- Thermostat Connections: Connect your iT600 series wireless thermostats to the system. The KL08RF communicates wirelessly with these thermostats via the CO10RF USB coordinator.
4.3 Wireless Pairing (iT600 System)
The KL08RF acts as a receiver for wireless signals from iT600 series thermostats. The CO10RF USB coordinator facilitates this communication.
- Ensure the CO10RF USB coordinator is securely inserted into the USB port on the KL08RF.
- Follow the pairing instructions provided with your specific iT600 thermostats to link them to the KL08RF wiring centre. This typically involves putting both devices into a pairing mode.
- Once paired, the thermostats will wirelessly send heating demands to the KL08RF, which will then activate the corresponding zone actuators, pump, and boiler.
5. Operating the KL08RF
5.1 Indicator Lights
The KL08RF features several LED indicators to provide status information:
- Power LED: Illuminates when the unit is receiving power.
- Network Status LED: Indicates the status of the wireless network (e.g., solid for connected, flashing for searching).
- Pair LED: Used during the pairing process with thermostats.
- Zone LEDs (1-8): Each LED illuminates when its corresponding zone is active and calling for heat.
- Pump LED: Illuminates when the pump output is active.
- Boiler LED: Illuminates when the boiler output is active.
5.2 Basic Operation
Once installed and paired, the KL08RF operates automatically based on the demands from the connected iT600 thermostats. When a thermostat calls for heat in a specific zone, the KL08RF will:
- Activate the actuator for that zone.
- Activate the heating pump.
- Signal the boiler to fire (if connected).
The system will continue to operate until the thermostat's setpoint is reached or the heating demand is cancelled.
6. Maintenance
The Salus Controls KL08RF wiring centre requires minimal maintenance. Follow these guidelines:
- Periodically inspect the wiring connections to ensure they remain secure.
- Keep the unit clean and free from dust. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- Ensure the ventilation slots (if any) are not obstructed to prevent overheating.
7. Troubleshooting
If you experience issues with your KL08RF wiring centre, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to the unit (Power LED off) | No mains power; loose wiring connection; blown fuse/tripped breaker. | Check mains power supply. Verify wiring connections. Check household fuse box/circuit breaker. |
| Thermostat not communicating with KL08RF | Thermostat not paired; CO10RF USB coordinator not inserted or faulty; wireless interference; out of range. | Re-pair the thermostat. Ensure CO10RF is correctly inserted. Relocate devices to reduce interference. Check distance between devices. |
| Zone not heating (Zone LED off when it should be on) | Faulty actuator; wiring issue to actuator; thermostat not calling for heat. | Check actuator functionality. Verify wiring to the actuator. Check thermostat settings and battery. |
| Pump or Boiler not activating | Wiring issue to pump/boiler; pump/boiler fault; no zone calling for heat. | Verify pump/boiler wiring. Check pump/boiler for independent operation. Ensure at least one zone is calling for heat. |
If the problem persists after attempting these solutions, please contact Salus Controls technical support.
