I am currently in the process of constructing a "thermal aquarium chamber", used to study the responses of various species to warming temperatures in their aquatic environment.

The idea is to control a water heater (flow-through) via a ramp/soak PID (Auber SYL-2352P).

I have a very general question regarding the attached wiring diagram: **Is my wiring correct?** Is there anything I need to add or change? Have I overlooked something?

**Update for future visitors**

Just supplementing the original question for future visitors. I have tested the set-up (heating water from 20 °C to 30 °C in 0.3 °C/min-1 steps) and it worked. Here's a picture.
