Hi Eric,
this puppy is frying my brain. I have;
- Altered the resistances at the pots and brought them to the levels for -8°C (the evaporator temp where the thermistor is located. I increased the two 5V setting in the Thermistor model to 6.5V the OFF temp for 0°C. Is this correct?
- Inserted the Triac as per the MOC data sheet but could not find the identical one. Note how current continues to flow in the OFF period? When increasing the value of R15 from the data sheets 39R to 100k I can get the current to stop flowing on the OFF period, is this right?
- Have altered the heater resistance to 275R (the heater is 175W). The heater should draw 0.8A, the circuit is drawing about 1.15A, is the resy going into the circuitry?
I hope I am getting somewhere, I need some help please!
Cheers
Andrew
