You need to find what chip is doing the amplification on the cover shield, there is no documentation that I could find that describes anything about the cover shield. The only thing on the website saying thermocouple is "Thermocouple, add $6", detailed information doesn't even say thermocouples inputs are there and the wiring diagram has the cover shield and says which two inputs it is. TC1 = A11, TC2 = A4 meaning you use one of those and go to Pins.h in your firmware, find the board you use (67) and adjust these lines to match
#define TEMP_0_PIN 13 // ANALOG NUMBERING
#define TEMP_1_PIN 15 // ANALOG NUMBERING
to
#define TEMP_0_PIN
11 // ANALOG NUMBERING
#define TEMP_1_PIN 15 // ANALOG NUMBERING
or
#define TEMP_0_PIN
4 // ANALOG NUMBERING
#define TEMP_1_PIN 15 // ANALOG NUMBERING
and then you need to find what chip the board uses, either MAX6675, AD595 or AD597
// -2 is thermocouple with MAX6675 (only for sensor 0)
// -1 is thermocouple with AD595
-2 is of course for the 6675
-1 will work for the AD595 or AD597
and you use these numbers in this area
#define TEMP_SENSOR_0 1
so for the AD595 or 597 that line would be
#define TEMP_SENSOR_0
-1
all the above are settings for Marlin because I can read it with github, the procedure is pretty much the same for Repetier but if you need help with that you will have to wait until I can get home and read the firmware.
Make sure your host reads a realistic temperature before continuing or heating the hotend.
