Digital settable multifunction time relay
with display and Bluetooth with Eltako
Connect app. With 18 functions. 1 CO con-
tact potential free 10 A/250 V AC. 230 V
LED lamps up to 200 W, incandescent
lamps 2000 W*. With display lighting.
Standby loss 0.1-0.3 watt only.
Modular device for DIN-EN 60715 TH35 rail
mounting.
1 module = 18 mm wide, 58 mm deep.
With the patented Eltako Duplex technolo-
gy (DX) the normally potential-free con-
tacts can still switch in zero passage
when switching 230 V AC 50 Hz and there-
fore drastically reduce wear. Simply con-
nect the neutral conductor to the terminal
(N) and L to 15 (L) for this. This gives an
additional standby consumption of only
0.1 Watt.
Universal control voltage 12..230 V UC.
Supply voltage same as the control voltage.
Both functions and times are entered at the
touch of a key and indicated digitally on an LC
display. Only two keys are required for this pur-
pose.
When setting the time all values can be entered
within preset time ranges (0.1 to 9.9 or 1 to 99
seconds, minutes or hours). The longest possi-
ble setting is 99 hours. 600 settings are possi-
ble. The time setting is continuously displayed
digitally.
By using a bistable relay coil power loss and
heating is avoided even in the on mode.
The switched consumer may not be connected
to the mains before the short automatic syn-
chronisation after installation has terminated.
Functions
RV = off delay
AV = operate delay
AV+ = operate delay additive
TI = clock generator starting with
impulse
TP = clock generator starting with pause
IA = impulse controlled pickup delay (e.g.
automatic door opener)
IF = pulse shaper
EW =  eeting NO contact
AW =  eeting NC contact
EAW =  eeting NO contact and  eeting NC
contact
ARV = operate and release delay
ARV+ = operate and release delay additive
ES = impulse switch
SRV = release-delay impulse switch
ESV = impulse switch with release delay and
switch-off early- warning function
ER = relay
ON = permanent ON
OFF = permanent OFF
With TI, TP, IA, EAW, ARV and ARV+ functions,
a different second time can be entered also
with different time ranges.
The time relay is set either via Bluetooth
with the app or with the MODE and SET but-
tons, a button lock is possible.
The display lighting is switched on by pres-
sing MODE or SET for the  rst time.
20 seconds after you last press MODE or
SET, the program returns automatically to
normal display and the display illumination
goes off.
Connect the time relay to the app:
Press SET, the display shows BLE (Blue-
tooth) and the ID of the time relay. The con-
nection to the app can now be established
(delivery state PIN 123123).
Scan the QR code on the operating instruc-
tions, the app guides you through the lear-
ning process. After the connection to the
app has been established, BLE+ appears in
the display. The MODE and SET buttons are
now locked. After 20 minutes without inter-
acting with the time relay, the connection is
automatically disconnected.
Change PIN: The PIN for the Bluetooth con-
nection can be changed in the app under
the Device PIN entry.
Bluetooth reset (delete any changed PIN):
The connection to the app must be discon-
nected. Press MODE and SET simultaneous-
ly for 2 seconds, RES  ashes in the display.
Now press SET for 2 seconds, bLE appears
in the display. If you con rm with SET, the
BLE reset is carried out, the PIN is deleted
and the delivery status is restored.
Set the time relay with the MODE and SET
buttons:
Pressing the MODE button selects the LCD
element to be changed. The element cur-
rently being accessed  ashes. Pressing the
SET button changes the element being ac-
cessed. This can be the function, time
frame, time T1 or time T2 (TI, TP, IA, EAW,
ARV and ARV+ only). Each entry is termina-
ted with the MODE key. After setting the
time with MODE, no element  ashes anymo-
re - the time relay is ready for operation.
Press the MODE key again to restart the in-
put cycle. All the entered parameters are
retained if they are not changed using SET.
25 sec. after the last operation and if the
component still  ashes the input cycle is
automatically terminated and the previous-
ly made changes lapse.
Functions of the LC display:
If the ON or OFF function was selected, no
time is dis played, only ON and OFF and a
contact symbol in the correct position. On
all other functions, the set time, the func-
tion code and the contact symbol are shown
in the correct position (open or closed). The
clock symbol  ashes while the set time is
elapsing and the remaining time is shown.
Safety in the event of a power failure:
The set parameters are stored in an EEPROM
and are therefore immediately available again
when the power supply is restored after a
power failure.

The display lighting is switched on by pres-
sing MODE or SET for the  rst time.
20 seconds after you last press MODE or
SET, the program returns automatically to
normal display and the display illumination
goes off.
Connect the time relay to the app:
Press SET, the display shows BLE (Blue-
tooth) and the ID of the time relay. The con-
nection to the app can now be established
(delivery state PIN 123123).
Scan the QR code on the operating instruc-
tions, the app guides you through the lear-
ning process. After the connection to the
app has been established, BLE+ appears in
the display. The MODE and SET buttons are
now locked. After 20 minutes without inter-
acting with the time relay, the connection is
automatically disconnected.
Change PIN: The PIN for the Bluetooth con-
nection can be changed in the app under
the Device PIN entry.
Bluetooth reset (delete any changed PIN):
The connection to the app must be discon-
nected. Press MODE and SET simultaneous-
ly for 2 seconds, RES  ashes in the display.
Now press SET for 2 seconds, bLE appears
in the display. If you con rm with SET, the
BLE reset is carried out, the PIN is deleted
and the delivery status is restored.
Set the time relay with the MODE and SET
buttons:
Pressing the MODE button selects the LCD
element to be changed. The element cur-
rently being accessed  ashes. Pressing the
SET button changes the element being ac-
cessed. This can be the function, time
frame, time T1 or time T2 (TI, TP, IA, EAW,
ARV and ARV+ only). Each entry is termina-
ted with the MODE key. After setting the
time with MODE, no element  ashes anymo-
re - the time relay is ready for operation.
Press the MODE key again to restart the in-
put cycle. All the entered parameters are
retained if they are not changed using SET.
25 sec. after the last operation and if the
component still  ashes the input cycle is
automatically terminated and the previous-
ly made changes lapse.
Functions of the LC display:
If the ON or OFF function was selected, no
time is dis played, only ON and OFF and a
contact symbol in the correct position. On
all other functions, the set time, the func-
tion code and the contact symbol are shown
in the correct position (open or closed). The
clock symbol  ashes while the set time is
elapsing and the remaining time is shown.
Safety in the event of a power failure:
The set parameters are stored in an EEPROM
and are therefore immediately available again
when the power supply is restored after a
power failure.

1 module = 18 mm wide, 58 mm deep.
With the patented Eltako Duplex technolo-
gy (DX) the normally potential-free con-
tacts can still switch in zero passage
when switching 230 V AC 50 Hz and there-
fore drastically reduce wear. Simply con-
nect the neutral conductor to the terminal
(N) and L to 15 (L) for this. This gives an
additional standby consumption of only
0.1 Watt.
Universal control voltage 12..230 V UC.

Both functions and times are entered at the
touch of a key and indicated digitally on an LC
display. Only two keys are required for this pur-
pose.
When setting the time all values can be entered
within preset time ranges (0.1 to 9.9 or 1 to 99
seconds, minutes or hours). The longest possi-
ble setting is 99 hours. 600 settings are possi-
ble. The time setting is continuously displayed
digitally.
By using a bistable relay coil power loss and
heating is avoided even in the on mode.
The switched consumer may not be connected
to the mains before the short automatic syn-
chronisation after installation has terminated.

Digital settable multifunction time relay
with display and Bluetooth with Eltako
Connect app. With 18 functions. 1 CO con-
tact potential free 10 A/250 V AC. 230 V
LED lamps up to 200 W, incandescent
lamps 2000 W*. With display lighting.
Standby loss 0.1-0.3 watt only.
Modular device for DIN-EN 60715 TH35 rail
mounting.
1 module = 18 mm wide, 58 mm deep.
With the patented Eltako Duplex technolo-
gy (DX) the normally potential-free con-
tacts can still switch in zero passage
when switching 230 V AC 50 Hz and there-
fore drastically reduce wear. Simply con-
nect the neutral conductor to the terminal
(N) and L to 15 (L) for this. This gives an
additional standby consumption of only
0.1 Watt.
Universal control voltage 12..230 V UC.
Supply voltage same as the control voltage.
Both functions and times are entered at the
touch of a key and indicated digitally on an LC
display. Only two keys are required for this pur-
pose.
When setting the time all values can be entered
within preset time ranges (0.1 to 9.9 or 1 to 99
seconds, minutes or hours). The longest possi-
ble setting is 99 hours. 600 settings are possi-
ble. The time setting is continuously displayed
digitally.
By using a bistable relay coil power loss and
heating is avoided even in the on mode.
The switched consumer may not be connected
to the mains before the short automatic syn-
chronisation after installation has terminated.
Functions
RV = off delay
AV = operate delay
AV+ = operate delay additive
TI = clock generator starting with
impulse
TP = clock generator starting with pause
IA = impulse controlled pickup delay (e.g.
automatic door opener)
IF = pulse shaper
EW =  eeting NO contact
AW =  eeting NC contact
EAW =  eeting NO contact and  eeting NC
contact
ARV = operate and release delay
ARV+ = operate and release delay additive
ES = impulse switch
SRV = release-delay impulse switch
ESV = impulse switch with release delay and
switch-off early- warning function
ER = relay
ON = permanent ON
OFF = permanent OFF
With TI, TP, IA, EAW, ARV and ARV+ functions,
a different second time can be entered also
with different time ranges.
The time relay is set either via Bluetooth
with the app or with the MODE and SET but-
tons, a button lock is possible.
The display lighting is switched on by pres-
sing MODE or SET for the  rst time.
20 seconds after you last press MODE or
SET, the program returns automatically to
normal display and the display illumination
goes off.
Connect the time relay to the app:
Press SET, the display shows BLE (Blue-
tooth) and the ID of the time relay. The con-
nection to the app can now be established
(delivery state PIN 123123).
Scan the QR code on the operating instruc-
tions, the app guides you through the lear-
ning process. After the connection to the
app has been established, BLE+ appears in
the display. The MODE and SET buttons are
now locked. After 20 minutes without inter-
acting with the time relay, the connection is
automatically disconnected.
Change PIN: The PIN for the Bluetooth con-
nection can be changed in the app under
the Device PIN entry.
Bluetooth reset (delete any changed PIN):
The connection to the app must be discon-
nected. Press MODE and SET simultaneous-
ly for 2 seconds, RES  ashes in the display.
Now press SET for 2 seconds, bLE appears
in the display. If you con rm with SET, the
BLE reset is carried out, the PIN is deleted
and the delivery status is restored.
Set the time relay with the MODE and SET
buttons:
Pressing the MODE button selects the LCD
element to be changed. The element cur-
rently being accessed  ashes. Pressing the
SET button changes the element being ac-
cessed. This can be the function, time
frame, time T1 or time T2 (TI, TP, IA, EAW,
ARV and ARV+ only). Each entry is termina-
ted with the MODE key. After setting the
time with MODE, no element  ashes anymo-
re - the time relay is ready for operation.
Press the MODE key again to restart the in-
put cycle. All the entered parameters are
retained if they are not changed using SET.
25 sec. after the last operation and if the
component still  ashes the input cycle is
automatically terminated and the previous-
ly made changes lapse.
Functions of the LC display:
If the ON or OFF function was selected, no
time is dis played, only ON and OFF and a
contact symbol in the correct position. On
all other functions, the set time, the func-
tion code and the contact symbol are shown
in the correct position (open or closed). The
clock symbol  ashes while the set time is
elapsing and the remaining time is shown.
Safety in the event of a power failure:
The set parameters are stored in an EEPROM
and are therefore immediately available again
when the power supply is restored after a
power failure.
