On my panel display shows cool is on. But all my wires are going to power, sensor, and heat. No dots next to heat. Help…

Hello,  
Please understand that the ITC-1000 is judging the output on/off based on the current temperature and settings. If you have only the heater connected, the cooling output switching on will not affect it. Please check if your settings are correct.
