Installation procedure
Warning
IMPORTANT – mains electrical wiring is involved in the
installation of this controller, but no mains voltages are
connected directly to the controller. If you are in any doubt
please consult a qualified electrician.
Auto Reset Jumper
The ESTechnical reflow controller v4 PCB and onwards has a jumper
for enabling or disabling the auto-reset behaviour of the MCU. With
the jumper connecting the two pins it is possible to easily upload new
firmware to the controller via USB to serial connection from a
ESTechnical Reflow Oven Controller Upgrade T962

computer. With the jumper open, the MCU will not automatically
reset when the serial port is opened by a computer - this is more
convenient in normal operation and we suggest that you operate the
controller with the jumper open.

Small signal cable to the heater solid state relay, fitted with two pin JST connector.<
Mains cable that was used to supply the power for the oven cooling fan to the controller,

One cable that goes into the back of the oven, this is the oven cooling fan cable and has a
two pin connector fitted.<

pliers is needed – be careful the thermocouple is fragile. This reduces the mass of the
thermocouple junction and improves the response time to temperature changes.
