Frequently Asked Questions - GW14581 Gewiss

How to set the time and day on the Gewiss GW14581 timer switch?

Press the SET/PROG button once until 'SET' appears. Use the ▲ and ▼ buttons to set first the day (1=Monday...7=Sunday), then the hour, then the minutes. Confirm each setting with the MODE button or wait 30 seconds to exit.

How to program a time cycle (on/off)?

Press SET/PROG twice to enter 'PROG' mode. Select the day with ▲/▼ and confirm with MODE. Then set the time of the first transition (5-minute steps) with ▲/▼, confirm, then choose the output state (ON/OFF) with ▲/▼ and confirm. Repeat for each transition (up to 12 per hour). To copy the program to the next day, simultaneously press ▲ and ▼ after confirmation.

How to switch to manual mode and manually turn the load on/off?

Press MODE several times until 'MAN' appears on the screen. Use the ▲ or ▼ buttons to toggle the output between ON and OFF. The state remains until you change mode or reprogram.

What to do in case of power outage? Are the programs lost?

The GW14581 has a rechargeable backup battery (ML1220) that keeps the time and programs for about 24 hours. As long as the battery is operational, the programs are not lost. If the battery is discharged, only the time and day need to be reprogrammed; the programs remain in memory.

How to use remote control via GSM?

Connect the timer to the remote system GW90821 via terminals 4 (TX), 5 (GND), and 6 (RX). Send predefined SMS to change the mode (MAN/AUTO/OFF) or output state (ON/OFF). The device confirms by SMS and displays the remote control symbol on the screen.

The display does not light up, what should I check?

First check the 230 V~ power supply at terminals L and N. If the device is powered and the screen remains off, the backlight is only activated when a button is pressed. If nothing appears, try pressing a button. In case of malfunction, the self-test at startup (15 s) displays all icons; if not, the device may be defective.

How to copy the program from one day to the following days?

In PROG mode, after programming a day (e.g., Monday), instead of confirming normally, simultaneously press ▲ and ▼ within 30 seconds. The program is copied to the next day. Repeat the operation for each desired day.

How to reset the device to factory settings?

There is no direct software reset. To delete all programs, you can hold down all four buttons (MODE, ▲, ▼, SET/PROG) simultaneously for a few seconds. Note that this also disconnects the backup battery. Reconnect the power to reconnect the battery.

What type of relay is used and what load can it control?

The output contact is an isolated relay with a changeover (COM, NO, NC). It can switch resistive loads up to 8 A (AC1) or inductive loads up to 4 A (AC15) at 250 V~. Examples: lighting, awning motor, pump.

How to replace the internal battery?

Disconnect the power supply. Remove the small cover on the back of the housing (see figure A in the manual). Use a small screwdriver to extract the battery (type ML1220). Insert the new battery respecting polarity (+ facing up) and close the cover. The battery reconnects automatically when power is restored.

A move is made automatically to programming the next day.

The programming phase is exited by pressing the SET key or, in automatic mode, 30 seconds after the last key entry.

Save and propose again

If, however, it is required to copy the program directly to the next day, the programming just done is confirmed by pressing the keys simultaneously 30 seconds.

In this mode the program just run is saved and also proposed again the next day; to copy and save the same program over several days, repeat the operation of simultaneously pressing the keys within 30 seconds.

On completion of weekly programming the SET/PROG key is pressed to return to normal operating.

Automatic operation

The program is started by selecting automatic mode by pressing the MODE key until the AUTO symbol is displayed on the VDU.

In AUTO operating mode the hourly profile relative to the fraction of the day in progress (AP/PM) is displayed.

The profile relative to the other fraction of the day can be displayed by pressing the

AV keys simultaneously. The indication is active for 5 seconds, after which the current profile reappears.

Manual operation

1 2 3 4 5 6 7 16:28 ON MAN

The manual operating mode activated by pressing the MODE key until the MAN message is displayed on the VDU.

The Keys are used to set the required output status. The selected status (ON/OFF) is displayed on the VDU.

Visual display unit

The LCD visual display unit is provided with backlighting which is active for 5 secs whenever a key is pressed.

In SET or PROG mode the backlighting remains active during parameter setting and programming. It is deactivated on exit from these modes.

Remote control

The programmer can be connected to the GW90821 GSM remote control unit using a serial connection. SMS commands (e.g. from a cellular telephone) can be used to:

• Set the operating mode (MAN/AUTO/OFF)
• Set the output status (ON/OFF)
• Request the current status

Each command SMS sent to the device will be answered by a corresponding SMS in confirmation (with non-configurable predefined text); the status request message provides a reply including the following information:

• current operating mode (OFF/AUTO/MAN)
• output status (ON/OFF)

Whenever the output status or operating mode are modified from the remote control unit, the symbol is displayed on the VDU.

The symbol also appears for the current contact status request.
The symbol remains displayed on the VDU until a key is pressed.

Operating in case of blackout

The device is fitted with a backup battery that guarantees updating of the time and day of the week in case of blackout.

When power is supplied by the battery alone there is an autonomy of 24 hours in the following conditions:

• time display active
• backlighting inactive
• output status display inactive
• relay switching not enabled (the relay contact retains the status prior to the blackout)
• front keys inactive (except when all 4 keys are pressed simultaneously)

In the absence of power, simultaneously pressing all four front keys causes disconnection of the backup battery inside the device.

This function is used to preserve the efficiency of the battery when the device is not used for a long period.

The battery is connected again automatically once the device has been connected to the power mains.

The set programs are not lost either in the case of a blackout or in that of battery disconnection.
