Quick guide from the manual

The Salus 091FLRFv2 is a wireless weekly programmable thermostat designed for heating or cooling systems. The unit comes factory-paired with the RXRT510 receiver. Ensure installation is performed by a qualified professional. The thermostat requires 2x AA 1.5V alkaline batteries (do not use rechargeable batteries).

Installation

The thermostat should be mounted approximately 1.5m above floor level, away from heat sources, drafts, or direct sunlight. For wall mounting, use the provided template to drill holes. The device can also be used as a freestanding unit by unfolding the rear stand.

Receiver RXRT510

The receiver operates in two modes: AUTO (controlled by the thermostat) and MANUAL (controlled by switches on the receiver). For normal operation, set the switches to ON and AUTO. The receiver status is indicated by two LEDs: red (power/pairing) and green (heating signal).

Programming

The thermostat offers 9 programs: 0-5 are factory-defined (non-editable), and 6-8 are user-definable. To set the time, use the D, H, and M buttons. To set comfort or economic temperatures, use the Temp button followed by the sun or moon icons. Programs can be assigned to specific days of the week using the Prog and Prog# buttons.

Service Menu

To access advanced settings, hold the OK button for 5 seconds. Parameters include: heating/cooling mode, delay start (5 min), hysteresis (0.5°C or 1.0°C), temperature offset, relay output type, and pairing (SYNC).

Pairing

If communication is lost or a new receiver is added, use the SYNC function in the service menu. Ensure the receiver is in pairing mode (red LED flashing) before initiating the process on the thermostat.

Maintenance and Troubleshooting

Clean the device with a soft, damp cloth. Do not use abrasive cleaners or solvents. If the thermostat does not respond, a factory reset can be performed using the small hole next to the OK button (use a paperclip, not a pencil). If the red LED on the receiver continues to flash after 10 minutes, check for obstacles or interference between the devices.

Practical help

Common problems

Receiver red LED flashing

Indicates standby mode (no signal for 1 hour), pairing mode, or lost connection. Check battery levels in the thermostat and ensure it is within range.

Thermostat not controlling heating

Verify receiver switches are set to ON and AUTO. Test radio transmission by setting a higher target temperature and checking for the antenna symbol.

Reset button not working or damaging device

Do not use a pencil to press the reset button; graphite can cause a short circuit. Use a paperclip.

Before use

  • Install 2x AA 1.5V alkaline batteries in the thermostat.
  • Ensure receiver is connected to 230V AC power.
  • Set receiver switches to ON and AUTO positions.
  • Verify thermostat and receiver are within 60m range.
  • Check that the installation location is free from metal obstacles or thick walls.
