Perfect, easy. My inlet water temp on pool heater reading way high when it wasn’t. This was a direct replacement and works perfectly. MAKE SURE YOU TURN OFF THE BREAKER. I took out a dozen screws on the outside panel and screws on an inside panel Saved me hundreds of $ I’m sure. 🤑 Videos ard on youtube tooThis was perfect because for my aquacal heater you have to call the manufacturer for service and I could never get through 😖
