You need to place the PCB centrally in the oven between the top and bottom sensors. It is very important that the PCB is placed under the sensor so that the sensor does not receive any radiated heat from the preheater (bottom) IR-lamps.This ensures that the temperature control will function properly.
When precise temperature readings on the PCB are required, place the external sensor thermocouple directly to the PCB in order to measure the temperature on its surface. Secure it with Kaptopn tape or solder it using solder wire with high melting tmperature to the top or the bottom of the PCB.
Using the oven: Use the arrow keys to navigate the menu. To select a program, click until you see "Program" in the menu. Select program (1-5) and wait a few seconds for the machine to confirm the selection. To exit the menu, select the Quit-item and press Ok. Then press Ok to start the program. Here's a list of the current programs, their timings and peak temperatures. The first 3 are default programs.

Solder Paste
Eurocircuit recommends using SAC305 (SN96,5Ag3.0Cu0.5), a lead free paste that typically melts at around 227°C. It is however not fully melted at this temperature as explained here: SAC305 begins to melt at 217°C, reaching its fully liquid state at approximately 220.6°C. Recommended reflow temperatures are typically at least 13°C higher than melting temperatures; hence the SAC305 peak temperature window of 233 – 255.
We have done several tests and in general, you have to turn on the Holdtime (in menu) to achieve full wetting at the top temperature. Also be sure to place the board in the middle of the oven since the sides do not heat as much.
Elias has tested P2 and it worked with TS391SNL50. Jensa has tested P2 with SAC305/4900P-250G with disappointing results. Parts of the solder didn't wet at all and all Flux was dried out. Due to this, P4 was changed to have a higher final temperature of 249C to use with this paste. This is consistent with what Aim Solder writes.
