Frequently Asked Questions - 01923 Vimar

How to pair the 01923 receiver with a chronothermostat?

To pair the receiver, first replace the relay module of the chronothermostat with the RF transmitter module 01921.1. Then, on the chronothermostat, start the RF configuration (depending on model: 01910 or 01911) and press the P button on the receiver until the green LED flashes. The red LED of the configured channel flashes to confirm pairing.

What to do if the green LED does not light up on the receiver?

Check that the 230 V~ power supply is present and that the receiver is correctly connected (terminals L and N). If the LED remains off, check the fuse or main switch. The receiver must be permanently powered.

How many channels can I configure on the 01923 receiver?

The 01923 model is a 1-channel receiver. For 4 channels, use the 01924 model. During configuration, always select channel 1 on the chronothermostat.

How to check RF reception quality?

Press the P button on the receiver: the number of red LEDs lit indicates the reception level: 1 (poor), 2 (fair), 3 (good), 4 (excellent). If reception is poor, move the devices closer or use an external antenna.

What to do if the receiver stops responding after a failure?

Perform a reset by holding the P button for 5 seconds until all LEDs flash. This clears all memorizations. Then repeat the pairing procedure with the chronothermostat.

What type of antenna should I use?

Use a 17 cm rigid wire (not supplied) connected to terminal Y, placed vertically. You can also use a 433 MHz antenna with coaxial cable for remote installation. The antenna is mandatory for operation.

Can the receiver directly control a pump or solenoid valve?

Yes, the relay output (terminals C, NO, NC) can control a circulation pump, solenoid valve, or any other device operating at 230 V~, with a maximum current of 6 A (resistive) or 2 A (inductive). Observe the rated power.

How to clean the receiver?

Disconnect the power before any cleaning. Use a dry, lint-free cloth to wipe the surface. Do not use chemicals, alcohol, or solvents. Avoid moisture.

What safety precautions should be observed?

Installation must be carried out by a qualified electrician. Disconnect the main power before any intervention. Use cables with a minimum cross-section of 1.5 mm² and tighten the terminals properly. Observe the ambient conditions (0-55°C, IP40).

Is this receiver compatible with other thermostat brands?

No, the receiver is designed exclusively for the Vimar chronothermostats 01910 and 01911 using the RF transmitter module 01921.1. It is not compatible with other brands or protocols.

VIMAR

1. DESCRIPTION.

Radiofrequency actuator-receiver, for DIN (60715 TH35) rail installation, occupies 6 17,5 mm modules, RAL 7035 grey.

01923: 1 channel - 01924: 4 channels.

2. OPERATING MODE.

Illuminated green LED indicates that the power is on.

When an encoded signal is received from from the 01910 or 01911 programmable thermostat, the corresponding channel is activated and the associated red LED lights up. If no valid transmissions take place within 1 hour, the channel is closed down for the safety of the system.

3. CONFIGURATION OF 01910 PROGRAMMABLE CHRONOTHERMOSTATS.

• Replace the relay unit installed in the 01910 programmable chronothermostat with the 01921.1 radio-frequency transmitter unit (for the replacement operation, refer to the instruction booklet of the programmable chronothermostat).

• Check that the symbol 🎨 appears on the programmable thermostat display (wait max. 2 minutes for automatic detection).

• On the programmable thermostat, simultaneously press the OK button and the button ; a screen appears displaying channel CH 0x. Press the button , to select the desired channel (from 1 to 4) corresponding to the relay to be activated (select channel 1 for the 01923... receiver).
  Press the OK button: this initiates the configuration transmission phase; it is signalled by a blinking cursor and antenna icon.

• The transmission continues for about 2 minutes, after which normal operation is automatically resumed.
• During transmission, on receivers 01923 or 01924, press the button P until the green LED starts to blink. Wait until the channel has been programmed, signalled by the blinking of the red led associated with that channel.

• To display the reception level, press the button P; the level is indicated by the number of red LEDs which light up:

• red LED 1: poor reception

• red LED 2: adequate reception
• red LED 3: good reception
• red LED 4: excellent reception

Press the button P a second time to exit programming mode.

- To finish the procedure, press button C on the programmable thermostat. In the case of the 01924 four channel actuator-receiver, repeat the procedure to configure the other channels.

4. CONFIGURATION OF PROGRAMMABLE CHRONOTHERMOSTATS 01911.

• Replace the relay module in the timer-thermostat 01911 with the radio-frequency transmitter module 01921.1.
• On the timer-thermostat, go to the SETTINGS menu and select CONFIG. RF; the screen will show CONFIG. RF. Using the rotary knob, select the desired channel (from 1 to 4) corresponding to the relay you want to control (if using receiver 01923 always select channel 1). Press the ⚙ selection button; the configuration transmission phase commences.
• The transmission continues for 40 seconds, then the system stops the procedure and goes back to the CONFIG RF menu item. The transmission can be stopped manually by pressing the selection button a second time.
• During the transmission, on the receiver 01923 or 01924 press button P until the green LED blinks. Wait for channel programming to be signalled by the red LED corresponding to this channel blinking.

- To display the level of reception press button P until the green LED goes out; the level is shown by the number of red LEDs that light up:

• red LED 1: poor reception
• red LED 2: sufficient reception
• red LED 3: good reception
• red LED 4: optimum reception

Press button P until the green LED lights up again, to exit the programming phase.

- If it has not yet ended automatically, stop the timer-thermostat transmitting the configuration, press the ⚙ selection button. If using the 4-channel actuator 01924, repeat the procedure for each of the channels you want to configure.

5. RESET PROCEDURE.

Press and hold down the button P for 5 seconds; this will clear all the values stored in memory. The operation is signalled by the simultaneous blinking of all the red LEDs and the green LED.
