it was just a dry run...my parents house temp is set to 60 degrees so 80 degrees was more than enough to get it up to temp. i placed it directly on the heat tape and placed some of the plastic bins in for heat retention. The probe never got past the 60 degree room temperature and the thermostat was on as if it was trying to heat but the temp never increase per the thermostat. I gripped the probe in my hand and the temp shot up immediately to around body temp so i do know it is reading correctly. Just weird. Ill have to do some tinkering tonight. Anyone else use the stc-1000 that may have any ideas? i got the simple fahrenheit model

Do you have a volt meter that you can use to check to see if the output on the thermostat has voltage when cycled on? If not, you can plug in a lamp to see if the light goes on and off when cycled.


Edit... Just looked at the controller on the Ebay link you posted. It is just an simple on/off relay type PID controller. Do you have your heat span set up correctly? Looks like it can be set from 1°-24°. Meaning, if you have the temp span set to 20°, the relay wont engage (energize) unless the temperature of the probe is more than 20° lower than the setpoint and wont disengage (de-energize) until the temp is more than 20° above the setpoint. You need to really make sure you only have your temp differential set to 2-3°.
