Frequently Asked Questions - KIT THERMO DIGI 24 HF FLASH

How to install the DIGI 24 HF kit?

Place the transmitter (thermostat) on an interior wall 1.5 m from the ground, away from heat sources. Use the supplied base to place or fix it to the wall. The wall receiver is fixed near the boiler. Connect it to the mains (230 V) and connect it to the boiler according to the supplied diagram (brown=phase, blue=neutral, grey/black=boiler connection). The coding is already done at the factory, so the set is immediately operational.

How to set the time on the thermostat?

After pressing RESET, the time flashes (12:00). Use the + and - buttons to set the time (press and hold to scroll faster). Confirm with OK. To change the time later, press MODE until the ▲ pointer appears under the clock, then set as above.

What programs are available and how to select them?

Four programs are available: P1 (comfort 6h-23h), P2 (comfort 6h-8h30 and 16h30-23h), P3 (comfort 6h-8h30, 11h30-13h30 and 16h30-23h) and P4 (free program). To select P1, P2 or P3: press PROG P1-P4 until the desired number flashes, then confirm with OK. P4 is created by configuring 30-minute slots (full thermometer = comfort, empty = economy).

How to create a custom P4 program?

From Auto mode, press PROG P1-P4. Press again to select flashing P4. The screen displays 0:00 and the first thermometer flashes. Use + and - to advance/rewind in 30-minute steps. For each comfort period, position at the start time, then press the ⚠ key (or confirm key) to toggle the thermometer to full (comfort). Repeat for each transition. Confirm with OK then press MODE to return to Auto.

How to switch to manual mode and set a constant temperature?

Press MODE until the ▲ pointer is under Manu. Use + or - to set the desired temperature (from 5°C to 30°C). To return to Auto mode, press MODE and reposition the pointer under Auto.

How to activate extended absence (holiday) mode?

Press the key (holiday mode). The day flashes. For permanent override, press - once until FORC flashes, confirm with OK, set the frost protection temperature with +/- and confirm. For a defined duration: with +/-, set the number of days (1-99), confirm with OK, set the temperature, confirm. The thermostat returns to Auto at the end of the period. To cancel, press MODE.

What is the radio range between transmitter and receiver?

The typical range is 75 meters in free field and can go through up to 3 floors in typical housing. The frequency used is 433.92 MHz. If the connection is disturbed, move the devices closer or reconfigure the coding.

What to do if the heating does not turn on?

Check that the OK led on the receiver is lit (mains power). If not, check the fuse/circuit breaker. Ensure the transmitter is within range (max 75 m). If the led is lit but the heating does not work, there may be a coding problem: perform a reconfiguration (press the receiver button for 3 seconds until it flashes, then press Reset on the transmitter). Also check that Auto mode is active and that the set temperature is higher than the room temperature.

How to replace the transmitter batteries?

As soon as the low battery indicator appears at the bottom right of the screen, replace the batteries. Use 2 alkaline batteries LR6 1.5 V. Open the cover, insert the batteries respecting polarity. The thermostat retains its programs for about 60 seconds after battery removal. Battery life is 12 months.

What settings are possible on the back of the device?

On the back of the transmitter (unplugged), you can select: 1- Installation type (Heating or Air conditioning); 2- Regulation mode (On/Off or Chronoproportional for underfloor heating); 3- Anti-sticking function for circulation pump (on/off). These settings are made via switches or jumpers (not described in detail, see the manual).

Product presentation

The thermostat DIGI 24 HF

Easy to install, easy to program, the kit DIGI 24 HF will allow you to control your heating system in accordance with your way of life.

The IP43 wall-mounting receiver

The IP43 wall-mounting receiver can be easily installed close to the boiler. The thermostat DIGI 24 HF will control the ambient temperature in the dwelling and will transmit ON and OFF signals to the receiver.

① Pushbutton for configuration and priority setting.
② Indicator of Power on and coding light. LED on = product is powered on. This LED flickers during coding operations.
③ Operation indicator light. The LED is on when receiver's output contact is closed = ON.

Important: the transmitter and receiver assembly is factory coded and is therefore immediately operational.

There is no need to recode.

▶ Inserting or re-inserting the batteries

This clock thermostat is equipped with a warning light to indicate when the batteries need replacing. As soon as this indicator lights up at the bottom right-hand side of the display panel, replace the batteries (use two 1.5V LR6 alkaline batteries, life is approximately 12 months).

The device remains programmed for 60 seconds while batteries are being replaced.

Reset

Before beginning the programming of the device, please slide cover down and press RESET with the tip of a pen.

The Thermoflash DIGI 24 HF kit has been designed to offer you comfort and energy savings. It will be easily installed in your home and will control the ambient temperature according to the program. It will control through radio waves the RF receiver which may be fitted close to the boiler or the heating system.

The Thermoflash DIGI 24 HF kit will control the ambient temperature according to 3 temperature levels.

• Comfort temperature: this is the temperature for your hours of presence.
• Reduced temperature: this is the temperature for your brief absences or during the night.
• Frost protection temperature: this is the minimum temperature for long absences. It protects your dwelling from the risk of frost.

Installation of thermoflash DIGI 24 HF

To control accurately the ambient temperature, the DIGI 24 HF must be installed 1,5 m. above the floor, on an internal wall shaded from direct sunlight and from all thermal influences such as: television, lamps, heater, etc.

The DIGI 24 HF is delivered with a base. With this accessory, you can simply put it on a furniture. It is important to check that no external influence will perturb it (heater, window etc.).

You can also install it on an internal wall.

• Therefore, take out its wall mounting base.

The current temperature level indicator (comfort or reduced) will begin flashing. This modification ends with the next change in programmed temperature.

To return to the initial programme press MODE and re-position the pointer ▲ under Auto.

The current temperature level indicator (comfort or reduced) will stop flashing when the temporary modification comes to an end.

Prolonged absence mode (holidays)

This mode protects your dwelling from freezing by maintaining a minimum adjustable temperature in your dwelling during your absences.

You can programme the length of your absence so that the temperature rises for your return.

2 different settings are available for maintaining temperature above frost level:

Permanent frost protection

The receiver returns to the Auto mode.

Priority setting

Manual control is provided for this product.

- Press shortly receiver's ① pushbutton (<3 sec). Each press reverses output state.

Note: radio control retains priority.

Troubleshootings

• The heating does not start:
- receiver's power supply is cut off (OK ② light is off). Check fuse and circuit breaker.
- Receiver is outside of transmitter's range:
- move transmitter closer to receiver.
- Receiver does not recognize transmitter's code:
- re-install receiver.
- The system does not start or does not stop:

- the receiver or transmitter is disturbed by radio transmission (radio ham, TV monitor, cellular phone re-transmitter, etc.): attempt to remove the source of disturbance.

In case of persistent problem, call on your electrician.

Receiver installation

Before working on the installation, isolate all electrical supplies. All electrical wiring must be carried out by a qualified person.

For easier installation, the Thermoflash DIGI 24 HF kit is supplied with a flexible 4-wire 1.5 mm ^2 cable of 1.20m length (not connected).

We recommend using this cable for connecting the HF receiver according to the following colour codes:

$$ \text { brown } = \text { phase } $$

$$ \text { blue } = \text { neutral } $$
