Frequently Asked Questions - RF 4890 DELTA DORE

How to pair the RF 4890 receiver with a Tybox thermostat?

Put the receiver in pairing mode by pressing its button for 3 seconds until the left LED blinks. On the thermostat, wake up the display by briefly pressing a key, then simultaneously press the mode and + keys for 3 seconds. The screen displays rF00. Briefly press + to start scanning: the screen blinks and displays rF01 when pairing is successful. Check that the receiver LED stops blinking. To exit, press mode and + simultaneously.

What to do if the receiver LED stays on solid?

A solid LED indicates that the receiver is powered on and operating normally. If the LED does not blink after a pairing attempt, check that the thermostat is in pairing mode and that the thermostat batteries are sufficient.

How to reset the RF 4890 receiver?

To reset the pairings, press and hold the receiver button for 10 seconds until the left LED blinks rapidly. Release: all pairings are cleared. You will then need to re-pair the receiver with your thermostat.

What does the right blinking LED mean?

The right LED blinks when powering on to indicate that the receiver is waiting for mode selection (heating or air conditioning). Briefly press the button to choose the mode. A solid LED confirms the selected mode.

Why does the left LED blink after pairing?

If the left LED blinks after pairing, it may indicate a radio transmission conflict or loss of link. Check that both devices are within range (max 100 m) and that no metal obstacles are interfering with the signal. Reattempt pairing.

Can I use the receiver with a thermostat from another brand?

No, the RF 4890 receiver is designed to work exclusively with Delta Dore (Tybox) thermostats. Using it with another transmitter may damage the devices or cause malfunction.

How to switch from heating to air conditioning mode?

On the paired thermostat, wake up the display and press the mode key twice to switch between heating and air conditioning. The receiver automatically adapts to the selected mode. Check that the receiver LED indicates the correct mode (solid).

What to do if the receiver no longer responds to thermostat commands?

Check the power supply of the receiver and the thermostat batteries. Move the devices closer together. If the problem persists, perform a receiver reset (see dedicated question) and a new pairing. If nothing works, contact Delta Dore customer service.

Can the receiver control multiple devices simultaneously?

No, the RF 4890 receiver controls a single device (heating or air conditioning) via relay. To control multiple zones, you must use one receiver per zone, each paired with a separate thermostat.

What is the maximum range between the thermostat and the receiver?

The radio range is approximately 100 meters in open field. Walls, partitions, and metal objects can reduce this distance. Avoid installing the devices near large metal appliances or sources of interference.

INSTALLATION

1. Installing the transmitter

1.1 Location

The thermostat can be mounted on the wall or placed on a piece of furniture in a room whose temperature is representative of the location's average temperature, with a recommended height of 1.5 m, and it should also be nowhere near any heat sources (fireworks, sunlight, etc.) or air flows (window, door, etc.).

IMPORTANT: Do not install the thermostat on an external wall or with an unheated room (e.g. garage, etc.)

1.2 Wall mounting

1 Remove the front panel.
2 Secure the thermostat to the surface using suitable screws.
③ Insert the batteries

WARNING: make sure you insert the batteries facing the right way and that they are the right type (no lithium batteries).

4 Replace the front panel.

1.3 Mounting on a base

① Remove the front panel.
② Insert the batteries

WARNING: make sure you insert the batteries facing the right way and that they are the right type (no lithium batteries).

③ Replace the front panel.
4 Insert the base into the back of the thermostat and place the device in the desire location (on a flat, non-metallic surface).
