Frequently Asked Questions - 14446.SL Vimar

How to set the time and day on the Vimar 14446.SL thermostat?

Press the P button until the day flashes. Use the ▲/▼ buttons to select the day, then press OK. Then set the hours and minutes in the same way.

How to program an automatic program?

Press P until PROG and the histogram appear. Select the day with ▲/▼, press OK. For each hour (0 to 23), set the temperature level (T1, T2, T3) with ▲/▼ and confirm with OK. To copy the program to the next day, press OK when COPY flashes.

What does the empty battery symbol mean?

The empty battery symbol indicates that the power batteries are worn out. The relay output is then forced to OFF. Replace the batteries as soon as possible to restore operation.

How to replace the batteries?

Remove the thermostat from its base. Open the battery compartment on the back. Replace the two AA LR6 batteries with new ones, respecting polarity. Put the device back on the base. Programs are preserved thanks to the backup battery.

How to activate frost protection mode?

Press the F button until the frost protection symbol flashes. Use ▲/▼ to set the desired temperature (4 to 15 °C), then press OK. This mode is not accessible in cooling.

Can I control the thermostat remotely?

Yes, via a telephone dialer connected to the INPUT terminals. When the contact is closed, the thermostat switches to manual mode and buttons are locked. When the contact is opened, it switches to frost protection (heating) or OFF (cooling).

How to switch from heating to cooling mode?

Press the P button until the flame or fan symbol flashes. Use ▲/▼ to select the desired mode (heating or cooling), then press OK.

What to do if the screen displays a flashing symbol?

A flashing symbol may indicate a low battery (battery symbol) or a mode awaiting setting. If the ☐ symbol flashes, the batteries need replacing. If it is a mode (e.g., flashing OFF), you must confirm with OK or make a setting.

How to reset the thermostat?

The manual mentions a reset function. Simply remove the batteries and the backup battery for a few seconds, then reinsert them. All settings will be cleared.

What is the battery life?

The battery life of AA batteries is more than one year under normal use. An empty battery symbol will alert you to replace them in time.

1. DESCRIPTION.

Electronic timer-thermostat for ON/OFF ambient temperature control (heating and air-conditioning), daily/weekly programming, class I temperature control device (contribution 1%), input for remote switching of phone dialer on/off, change-over relay output 5(2) A 250 V\~, powered by batteries AA LR6 1.5 V - 3 modules.

2. FIELD OF APPLICATION.

The appliance is designed to control room temperature by acting on the control circuit of the burner or circulation pump (heating) or on the control circuit of the air conditioner (air conditioning), ensuring an ideal temperature, every day, throughout the week.

The large display shows the room temperature, day, time, system operating status and the daily temperature profile set for the current program.

3. INSTALLATION.

The appliance must be installed in flush or surface mounting boxes with Eikon, Arké and Plana frames and plates at a height of 1.5 m off the floor in a suitable position for correctly detecting the ambient temperature. It must not be installed in niches, behind doors and curtains or in areas affected by sources of heat or atmospheric factors. In particular, it must not be installed on outer walls or in association with appliances that generate heat (e.g. dimmers or lamps).

It should be used in dry, dust-free places at a temperature between 0 °C and +40 °C.

4. FRONT VIEW, CONTROLS AND DISPLAY.

P: Access to programming mode.

C: Delete or return to the previous screen.

Mouse: To set numerical values and for scrolling.

OK: Confirm or continue to the next screen.

F: Select operating mode.

5. CONNECTIONS.

5.1 - Circulation pumps, burners, solenoid valves.

5.2 - Motorized valves.

5.3 - Phone dialler control.

It is possible to control the timer-thermostat remotely with a phone dialler connected to the INPUT terminals.

By closing the contact, the timer-thermostat is forced onto manual operation and the keys P, C, “▲” “▼” (horizontal bar), OK, F are locked (if any key is pressed the display will show the 🔊 symbol blinking for approximately 3 s).

On opening the contact the timer-thermostat is forced onto:

• Antifreeze mode if heating is on.
• OFF if air-conditioning is on. In this phase the keys of the timer-thermostat are not locked and it is possible to operate the device.

Connection with phone actuator with clean contact without potential only SELV environment.

5.4 - Insertion/Replacement of buffer battery.

The buffer battery (type CR2032) permits changing the settings and programming even when the appliance has been removed from its seat. In addition, it ensures updating the time and day and the operation of the display for at least 10 days if there is no mains voltage.

When the timer-thermostat is taken out of its seat the display shows the ☐ symbol.

It is not, moreover, possible to control the relay output.

The buffer battery is necessary for the appliance to work properly.

VIMAR

5.5 - Insertion/Replacement of supply battery.

The empty battery symbol ☐ on the display indicates that the battery charge is running down.

Warning! In this phase the output status is always OFF.

To restore operation it is necessary to change the batteries.

WEEE - Information for users

If the crossed-out bin symbol appears on the equipment or packaging, this means the product must not be included with other general waste at the end of its working life. The user must take the worn product to a sorted waste center, or return it to the retailer when purchasing a new one. Products for disposal can be consigned free of charge (without any new purchase obligation) to retailers with a sales area of at least 400 m², if they measure less than 25 cm. An efficient sorted waste collection for the environmentally friendly disposal of the used device, or its subsequent recycling, helps avoid the potential negative effects on the environment and people's health, and encourages the re-use and/or recycling of the construction materials.
