We have a small residential pool with Pentair equipment. Control of the UltraTemp 1200 heater is very barebones: Iʻve set the IntelliFlo pump to run from 9 am to 5 pm; when it stops, the UltraTemp kicks a low flow error and shuts down. This has worked fine, but our situation has just changed. Weʻve added PV solar to the house, and we no longer want the heater to come on whenever the pump is running - I want to wait to turn the heater on till around 10:30, when our solar gain is high and our battery is well charged.
This has to be totally simple - a programmable timer box with a control relay going to... what??? All the UltraTemp wiring information I can find is oriented towards connecting with their automation, and thereʻs nothing I can find that says, "To shut the heater manually, open such-and-such circuit at so-and-so point".
Does anybody know the heater well enough to give me some info? This isnʻt an issue of skill with electrical work - Iʻve spent years in hospital IT work, done a lot of electronics building and repair, and I ran a hydroelectric site for 10 years. The problem is simply that I canʻt get good schematics and information that tell me where the control points for the heater are.
