PID Temperature Controller Meter Indicator, Jaybva Digital Universal Thermostat C and Fahrenhe F Display SSR and Alarm Output 40A Solid State Relay and Thermocouple Probe Heat Sink Included

i am using it with a 120V 750W keenovo heatbed, and works very good, it heat fast and works right. Very happy with my purchase.

Been working great on my sportsman smoker. Instruction a little confusing but not bad .

Everything is fine with the product.

If anyone is having trouble understanding the directions, here is what I gathered and what I set them to for a heating element.USP = Upper Set PointLSP = Lower Set PointHY1 and HY2 Hystersis - How far off can temp be ex: set temp to 100, and HY to 1 and it won't adjust until temp hits 102DP - Decimal PointScy - Lock - skip itPuF - Adjust for temp offsetInp - Input TypeP - Porportional Band, adjust intervals, leave at 1I - Inverval, 540x a secondd - Derivative- predicts the future needs.Out - Heat or ColdHys - Set at one, not used if using Derivative-Ctl - Set to 1 for digitial, not needed for electronic relayC - F Centigrade or FareniheightAL01 & AL02 = AlarmsA01 and A02 - leave at 2, there are 7 settings, but not used for heating elementHold SetUSP = 214LSP - SkipHY1 = 1HY2 = 1DP = 0Scy - SkipAl1 =300A01 = 2Al2 = 300A02 =2PUF = 4.5 - Calibrated to what the top of my kettle was reading.Inp = Try each one until you find the one that works for your probeP = 1I = 540d = On/200.00HeatHys = 1Ctl = 001C- F = FLck - skipHold Blue button for Auto Tune

The controllers are great, Five Stars, easy to use, accurate.However two out of four of the 40 Amp relays failed (in the on mode, causing thermal runaway) after a couple weeks of use on a 220 V 23 Amp resistive heater load. They should not be rated at 40 Amps 220 V. Two of them are holding up fine on 110v 10 amp loads for several months of regular use.The thermocouples have too high thermal resistance to work in air, they also had to be replaced with bare junction wires.

When you order the PID, you not only get the PID controller, but you also get the Solid State Relay and Heat Sink. You also get a thermal coupler. This is a complete package for building a temperature controller. The only other items are needed are a power cord and switch.

I had no issues with the instructions or getting it to work, and nowhere does it say the probe is waterproof but I guess I was hoping it was. Easy fix.

Wired everything up. The Solid State Relay would not release. Even tried disconnecting the control input. I didn't have it hooked up in the return period but it is still under the warranty period. Jaybva offered to replace it in 20 days or give me $10. I took the $10 and bought a $19 SSR. Wired it in and everything was working great, for 4 hours, then the controller died. I don't believe these devices will function anywhere near their spec'd values. The original SSR was rated for 40 amps. I was running around 19 amps. The controller was rated for a max of 260V. I was running 220V.
