SN74LVC1G175: Regarding the initial state of the Flip Flop

Tool/software:

Hi team,

We are using SN74LVC1G175DCKR for our over temperature protection circuit. 

We have a heating coil, when the temperature of the heating coil crosses threshold, the heater need to turn off and remain off  even if the temperature drops below the threshold until a reset button is pressed. 

So we have implemented the circuit using a comparator, D Flip Flop for the same.

The requirement conditions are as follows

1. Heating coil turns off when the temperature goes above the Threshold

2. Remains off even when the temperature drops

3. When the temperature drops below threshold and reset is pressed, the heater need to turn on

4. When the temperature is high and reset is pressed, the heater need to remain off.

5. When the temperature is high and power is recycled ( or toggled),the heater need to remain off.

6. When the temperature is low and power is recycled ( or toggled),the heater need to turn on.

While testing the above circuit, The 6th condition is not satisfying. Other than that all the other conditions are satisfied.

The issue is, when the temperature is high and the power is recycled, The heater will turns on. It will turns off when the temperature drops below the threshold which is just the opposite of our Logic. I'm not about the reason. May I know the initial state of this module during the power up.

please find the schematic implementation for your reference. Kindly check it and let us know your comments.
