Amp rating for heating circuit on ITC-1000F and concerns over cooling issues

I don’t see any figures anywhere. Curious on this and i have seen that Amazon recommends an aux cooling fan for it. Is cooling an issue with these temp controllers?

The ITC-1000F can withstand a current of 10A.
Please refer to the settings:

When the temperature reaches/ lower than TS-DS, it will turn on the heater, turn off at TS.
When the temperature reaches/ higher than TS+DS, it will turn on the cooler, turn off at TS.

For example, want to control 25°C, temperature range is 23°C ~27°C. Please set TS=25, DS=2. Then it will turn on heater at 23°C (TS-DS), turn off at 25°C. Turn on cooler at 27°C (TS+DS), turn off at 25°C.
