Features & Specifications
A single transmitter key press activates two independent outputs. Each output can be configured as toggle, pulse or pulse
with timer. This allows you to e.g. start two different timers, have a pulsed and a timed output, have two galvanically
separated outputs etc.
Velleman hereby certifies that the device K8070 meets the essential requirements and all other relevant
stipulations of directive 1999/5/EG and 1995/5/EC.

Assembly hints
1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.
1.1 Make sure you have the right tools:
• A good quality soldering iron (25-40W) with a small tip.
• Wipe it oftenon a wet sponge or cloth, to keepit clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’and will
protect the tip,and enables youto make goodconnections. When solderrolls off the tip,it needs cleaning.
• Thin raisin-core solder. Do not use any flux or grease.
• A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they
cannot fly towards the eyes.
• Needle nose pliers, for bending leads, or to hold components in place.
• Small blade and Phillips screwdrivers. A basic range is fine.
For some projects, a basic multi-meter is required, or might be handy
1.2 Assembly Hints :
⇒ Make sure the skill level matches your experience, to avoid disappointments.
⇒ Follow the instructions carefully. Read and understand the entire step before you perform each operation.
⇒ Perform the assembly in the correct order as stated in this manual
⇒ Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.
⇒ Values on the circuit diagram are subject to changes.
⇒ Values in this assembly guide are correct*
⇒ Use the check-boxes to mark your progress.
⇒ Please read the included information on safety and customer service
* Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’on a separate leaflet.

1.3 Soldering Hints :
1- Mount the component against the PCB surface and carefully solder the leads
2- Make sure the solder joints are cone-shaped and shiny
3- Trim excess leads as close as possible to the solder joint
REMOVE THEM FROM THE TAPE ONE AT A TIME !

MAX. 2A

12
Configuration
At power-on, LD1 will flash a # of times, hereby indicating that the unit is operational. Next, LD4 will turn-on.
At first power-on, the unit will respond to channel(1)/button(1) of the K8058/VM118R transmitter. Make sure the transmitter
buttons are configured as 'pulse' (check your K8058/VM118R manual).
17. Configuration
1. Hold 'setup'-button. LD1 turns on.
2. Hold a remote button (1..8)
3. LD4 will light when the button has been stored
4. Release all buttons
Repeat steps 1 trough 4 to learn other remote buttons or remotes.
 31 transmitters or transmitter-buttons can be stored.
 If the memory is full, both LD1 and LD4 will flash rapidly.
18. To learn a remote(button):
1. Turn off the power.
2. Hold 'setup'-button.
3. Turn on power. LD1 and LD4 will start flashing
4. Release 'setup' when LD1 and LD4 stop flashing
 This process takes about 10 seconds.
 If the button is released before the leds stop flashing, the memory will not be cleared.
 The unit will now respond to the default code only.
19. To remove all stored remotes from memory and to return to factory defaults

13
Configuration
1. Push 'setup'-button repeatedly to configure either left relay (LD2 lights) or right relay
(LD3 lights).
2. Confirm your selection with a long push (LD4 flashes 3 times). The selected relay will
remain ON.
3. Push 'setup'-button a number of times, depending on the desired mode (see table). At
each press, LD1 will flash a # of times, indicating the current mode.
4. Confirm with a long push (LD4 flashes 3 times). The selected relay will turn off and the
unit is ready for use.
 The unit will return to normal operation when left idle for 10s. The current mode will not
be changed.
If necessary, repeat sequence for the remaining channel.
Factory defaults: left relay-output: 0.5s timer right relay-output: 1h timer

21. Use
Pressing a transmitter button will operate both outputs simultaniously.
Each relay will behave according to the selected mode.
In '0.5s timer'-mode, the relay will remain on for as long as the remote button is held.
In 'ON/OFF'-mode, the relay will toggle between ON and OFF every time the remote button is pushed.
