Solar Thermal Systems Components FAQs
My sensor cable is only 4 feet long. How do I wire it from the controller all the way to the collectors? First off, when wiring to the collectors, make sure you use the high temp sensor (usually black or red). One end of the sensor cable has the sensor, which...
How do I get my SmartMaxx DHWPlus controller from Celcius to Farenheit? Push the "+" button until you move to end of the main menu (time). Press the "+" button continuously for about 3 seconds to get into the adjustment submenu. You should see "Arr." Temperature scale choice is near the...
What is involved in setting the drainback option (ODB) on my SmartMaxx-DHWPlus controller? In the submenu, switch ODB from “OFF” to “ON.” Four new items will appear in the submenu: tDTO, tFill, tSTB, and OBST. Some experimentation may be necessary to get these settings correct for your system. tDTO (time period switch-on)...

Can I Mount Solar Thermal Collectors On A Flat Roof Without Roof Penetrations? Yes you can. Collectors can be attached to our ballast system, which uses the weight of standard patio blocks to hold the collectors in place. Wind load calculations must be done by an engineer to conform to local...
How Can I Match Up Collector Connections On A Roof With The Rafters?
What is the best option for piping my solar hot water system?
Can I use PEX in a Solar Hot Water System? NO!!! PEX will fail in a Solar Hot Water System. Only FlowMaxx line set and standard L-Copper tubing is rated for the high thermal loads of Solar Hot Water Systems.
This answer depends on what you are trying to accomplish. For simple Domestic Hot Water systems you should try and position you collectors at the same angle as your latitude. For systems that are tied into the home heating system, as in a combisystem, you should position you collectors 15...
