Is there a way to change the temp of something like pump like you can do with filt and hswc?
The PROP tool is great for that. If you look in tools, there should be a 'PROP' element near the sign tool.
Click that, then click the 'type' box and choose temp. Then type in the temp you want in the number box below that,
hit OK, and draw over the pump you want to set the temp on.
