Operation description

The Multipurpose timer switch on the front consists of two capacitive buttons 1 and 3 and an LED indicator 2. With the buttons 1 and 3, we select, i.e. we set, the status, while the LED indicator informs the user about the current settings, i.e. the status of the EM82 switch.
The Multipurpose timer switch allows four modes of operation:

1. Switch (on | off)

When you press button 1 or 3 the switch turns on (status ON) and the indicator 2 lights up with the colour set for the ON status. When you press button 1 or 3 the switch turns off (status OFF) and the indicator 2 lights up with the colour set for the OFF status.

Figure 5 Turning ON and OFF the EM82 switch

2. Push button

When any of the buttons is pressed, the output turns ON and remains ON as long as the button is pressed down.

3. Relay

The switch is fully controlled via the input signal S and is switched on as long as a signal is present at the terminal S, otherwise it is switched off.

4. Timer (On and Off after elapsed time)

When the switch is in timer mode, it starts counting down the time after a short press on button 1 or 3. After the time has elapsed, the switch switches off. The timer can be switched off at any time by pressing button 1 or 3.
The same operation is achieved in the case of control via the input signal S.

TIMER RESET

If we want the timer to start counting from the beginning again while it is in the ON state, we can do this in two ways:

1. Switch off the timer by pressing button 1 or 3 and switch it on again by pressing button 1 or 3. The timer will start counting the time from the beginning.

2. The timer can also be reset during operation without switching it off. This is done by briefly pressing button 1 and 3. In this case, LED indicator 2 will flash twice with the colour set to OFF and then illuminate with the colour set to ON.

Description of the operation of the EM82 switch with control signal S

IMPORTANT

The user connects the mains voltage signal (230 VAC) to the connection terminal for control signal S! Control signal S operates in all the above-mentioned operating modes. Its function differs only when the EM82 switch is in the Relay mode.

Control signal S has two operating modes. Mode 1 operates in all switch modes and is described under section a).

Mode 2 only operates in the selected TIMER switch mode and is described under section b).

a) Operation of the control signal S - MODE 1

1. Selected mode: Switch | Push Button | Timer

When one of the operating modes (Switch, Push Button or Timer) is selected, the external signal has a push button function. This means that the state of the EM82 switch changes when a signal appears at terminal S.

Example: An external push button is connected to the terminal S, the EM82 switch is in the SWITCH operating mode and in the OFF state. When the user presses a button on the external push button, the state of the EM82 switch changes from OFF to ON. Regardless of how the external push button is pressed (long or short press), the state changes only once. When the button on the external button is pressed again, the state of the EM82 switch changes from ON to OFF.

Operation of the EM82 switch for various modes (Switch, Push Button and Timer in the selected mode of the control signal S - MODE 1) is presented in figures 6, 7, 8.

Figure 8 Display of the operation of the external signal S and buttons in the TIMER operating mode and external signal in MODE 1
Figure 9 Display of the operation of the external signal S and buttons in the PUSH BUTTON operating mode and external signal in MODE 1

2. Selected mode: Relay

When the Relay, operating mode is selected, the external signal has an On function. This means that the state of the EM82 switch changes to ON when the signal at terminal S. When the signal at terminal Sis no longer present, the state of the EM82 switch changes to OFF.

Example: An external push button is connected to the terminal S; the EM82 is in Relay and OFF state. When the user presses a button on the external push button, the state of the EM82 switch changes from OFF to ON. When the user releases the button on the external push button, the state of the EM82 switch changes to OFF.

Figure 10 Display of the operation of the external signal S and buttons in the RELAY operating mode and external signal in MODE 1

b) Operation of the control signal S - MODE 2

1. Selected mode: Switch | Push Button | Relay

When one of the modes (Switch, Push Button or Relay) is selected, the external signal has a push button function, the same as in MODE 1.

2. Selected mode: Timer

If TIMER mode is selected and the external signal S is in MODE 2, the external signal S turns on the timer with a delayed countdown start. When the external signal appears at the terminal S, the switch turns on; however, the timer does not start the countdown yet. At the moment that the signal is no longer present at the terminal S, the timer starts to countdown the set time and the switch turns off after the countdown is over.

If the EM82 switch is turned on by the external signal S, it can only be turned off by pressing either button 1 or 3.

Example: SM10 external switch that turns on the light is connected to the terminal S; the EM82 switch is in the TIMER (10 min) operating mode and the control signal S is in MODE 2. The EM82 switch is in the OFF state. The EM82 switch is placed in the bathroom and its output controls the ventilator. When the user turns on the bathroom light with the SM10 switch, the ventilator also turns on. When the user leaves the bathroom and turns off the light with the SM10 switch, this action also terminates the signal present at the terminal S which initiates the countdown of the EM82 switch. The ventilator stays turned on for 10 minutes, then it automatically turns off.

1. Operating mode settings

To enter the setting menu, where you can choose between the operating modes, press and hold both buttons 1 and 3 at the same time until the LED indicator 2 starts flashing white. When LED indicator 2 flashes five times (5x), we are in the settings menu. Here, the LED indicator flashes to indicate the currently selected operating mode (Table 4). Each beat cycle is separated by a 7-second pause.

Table 4 Possible switch operating modes
Program No. Indicator flashes Indicator colour Operation description

2. Colour settings of the LED indicator for each status

Possible colours: Red, Blue, Green, Purple, White, None

The colour and dimming settings of the LED indicator for an individual status are obtained as follows:

To change the colour of the LED indicator when the switch is OFF, hold down 1 or 3 for about 5 s until LED 2 starts flashing with the currently selected status colour (if the colour is "None", then the LED indicator will flash white). Use 1 or 3 to scroll through the list of possible colours.

If you want to decrease or increase the brightness of the LED indicator, do it by long pressing the 1 or 3 button. Button 1 increases the brightness power; button 3 decreases the brightness power.

Once the desired colour and brightness have been set, exit the menu with a long press (~ 5 s) on both buttons 1 and 3 until the LED indicator 2 flashes with the selected colour (if "None" is selected, then the LED will flash white).

The same procedure applies to setting the colour of the ON status indicator, except that to enter the settings, the switch must first be turned on and then button 1 or 3 must be pressed.

3. Operating mode settings of the external control signal S

You can set the operating mode of the external signal S on the EM82 switch. The description of the operation can be found in the chapter “Description of the operation of the switch with control signal S“.

You can select MODE 1 by selecting the preferred switch function (Switch, Push Button, Relay or Timer) and then press and hold buttons 1 and 3 3 at the same time for 5 seconds to exit the settings menu. MODE 1 is the default operating mode.

If you wish to set MODE 2 choose the TIMER operating mode and then press and hold buttons 1 and 3 at the same time for 5 seconds to exit the settings menu; make sure that external signal is always present at the control signal S while holding buttons 1 and 3.

Figure 20 Setting the operating mode of the input signal S for MODE 2

4. Storing the settings

The EM82 switch stores certain settings and parameters (Table 5) in memory, where they remain preserved even in the event of a power failure. The switch remembers the operating mode settings, the colour of the indicator in both statuses and the degree of dimming of the indicator each time the selected setting is changed. In addition, the switch in TIMER mode also remembers every 5 minutes how much time has elapsed since switching on and in what status the switch is (ON or OFF). In the event of a power failure, the switch returns to the pre-loss state after power is restored.

Table 5 List of settings to be stored in the permanent memory of the EM82 switch
Setting name Operating mode When
Switch status (ON | OFF) TIMER Every 5 min
Elapsed time TIMER Every 5 min
Switch program (switch, push button, relay, timer) All When the program changes
Indicator colour - state ON All When changing the colour
Indicator colour - state OFF All When changing the colour
Indicator brightness level All When changing brightness level
Operating mode of the input control signal S All When the program changes
Locking the device All When device is locked/unlocked

Example: The switch is in TIMER mode and selected program No. 11 (timer duration 45 min). The user presses the power button 1 or 3 and after 17 minutes the switch loses power. After the power is restored, the switch returns to the ON state, where it will remain for further 30 minutes, after which it will turn off.

5. Locking the EM82 switch

The EM82 allows the user to lock the device, preventing easy changing of the operating mode. We do this by pressing both buttons 1 and 3 at the same time and holding them until the LED indicator 2 starts flashing FAST in green colour. This happens after about 15 seconds. In the meantime, the LED indicator 2 will start flashing white twice, but this does not mean that the switch has locked, so keep going until the indicator starts flashing FAST in green colour.
After that, it is impossible to enter the settings menu for the mode of operation as well as for setting the colour of the LED indicator.
We unlock the device in the same way as we lock it.

6. Reset to factory settings

The EM82 switch also allows you to reset to factory settings (Table 3). To do this, press both buttons 1 and 3 at the same time and hold your finger until the LED indicator 2 flashes FAST in purple colour. This happens after about 25 seconds. In the meantime, the LED indicator 2 will start flashing white twice and after a while also fast with the green colour, but this does not mean that the EM82 switch has been reset, so keep holding until it switches colour to purple.
