Flow switch keeps tripping and shutting off thermostat : HVAC

Flow switch keeps tripping and shutting off thermostat. Hi, I have an AC / Air Handler from Carrier. The model is FX4BNF042. I am having a few issues: I'm having an issue where my thermostat keeps turning off. This is because my PVC pipe (might be for overflow) keeps filling up with water and it trips the flow sensor. When the sensor trips, the AC shuts off and so does the thermostat, as ...

What Causes GFCI Outlets to Keep Tripping? | Fluke

· When a GFCI outlet keeps tripping, there must be a reason. Instead of just resetting the GFCI, you should also investigate the cause of the trip. Ground faults occur when electrical current finds an unintended path to ground. The usual suspects for ground-faults include worn insulation, conductive dusts, water, or other "soft grounds." Ground faults account for more than 80% of equipment short ...

Thermistors - Nidec

The thermistor trip temperature determines the temperature at which the thermistor resistance rises to a very high value, thus tripping the controller. Thermistors are available with different trip temperatures. Each thermistor has one pre-set, non-adjustable switch point. We will bring all six (6) leads out unless specified otherwise.

Using a Thermistor | Thermistor | Adafruit Learning System

· A thermistor is a thermal resistor - a resistor that changes its resistance with temperature. Technically, all resistors are thermistors - their resistance changes slightly with temperature - but the change is usually very very small and difficult to measure. Thermistors are made so that the resistance changes drastically with temperature so that it can be 100 ohms or more of change per degree ...

THERMISTOR MONITORING RELAY | Foxtam Controls

Should the PTC sensor embedded within the motor windings resistance rise above KOhms due to a rise in motor temperature the output relay will de-energise and one of the LED’s will illuminate orange. Once tripped the motor temperature would have to cool sufficiently for the resistance to drop below KOhms to allow the output relay to re-energise again. The fixed tripping and reset ...
