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

  = fl eeting NO contact

AW

  = 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

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 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.

SRV

  =  With control impulses from 50ms 

the make contact switches to and

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.

ER

  =  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%.
