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

= off delay

= operate delay

AV+

= operate delay additive

= clock generator starting with

impulse

= clock generator starting with pause

= impulse controlled pickup delay (e.g.

automatic door opener)

= pulse shaper

= fl eeting NO contact

= fl eeting NC contact

EAW

= fl eeting NO contact and fl eeting NC

contact

ARV

= operate and release delay

ARV

+ = operate and release delay additive

= impulse switch

SRV

= release-delay impulse switch

ESV

= impulse switch with release delay and

switch-off early- warning function

= relay

= 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 fi 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

fl ashes in the display.

Now press SET for 2 seconds,

bLE

appears

in the display. If you confi 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 fl 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 fl 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 fl 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 fl 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.

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.

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

= off delay

= operate delay

AV+

= operate delay additive

= clock generator starting with

impulse

= clock generator starting with pause

= impulse controlled pickup delay (e.g.

automatic door opener)

= pulse shaper

= fl eeting NO contact

= fl eeting NC contact

EAW

= fl eeting NO contact and fl eeting NC

contact

ARV

= operate and release delay

ARV

+ = operate and release delay additive

= impulse switch

SRV

= release-delay impulse switch

ESV

= impulse switch with release delay and

switch-off early- warning function

= relay

= 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 fi 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

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

(delete any changed PIN):

The connection to the app must be discon-

nected. Press MODE and SET simultaneous-

ly for 2 seconds,

Now press SET for 2 seconds,

bLE

appears

in the display. If you confi 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 fl 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 fl ashes anymo-

Functions of the LC display:

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.

Description of functions

AV+

= Function same as AV. However, after

an interruption the elapsed time is

stored.

EAW

ARV

ARV+

= Same function as ARV, but after an

interruption of the operate delay the
elapsed time is stored.

= With control impulses from 50 ms

the make contact switches to and
fro.

SRV

= With control impulses from 50ms

the make contact switches to and
fro. In the contact position 15-18, the
device switches automatically to the
rest position 15-16 on delay time-out.

ESV

= Function same as SRV. Additionally

with switch-off early warning: ap-
prox. 30 sec. before time-out the
lighting starts fl ickering 3 times at
gradually shorter time intervals.

= As long as the control contact is

closed the make contact reverts
from 15-16 to 15-18.

* The maximum load can be used starting at

a delay time or clock cycle of 5 minutes.
The maximum load will be reduced for shorter
times as follows: up to 2 seconds 15%, up
to 2 minutes 30%, up to 5 minutes 60%.
