Will this work in the precision temp junior ot says on the unit rhogard is recomended with protec 922 inhibitor
I'm sorry I am not familiar with the Precision Temp products and I do not feel comfortable recommending any particular anti-freeze or inhibitor. The Rhogard anti-freeze you inquired about is sold specifically for use with the Buderus GB142 series boilers. I suggest contacting Precision Temp for information about where to purchase the appropriate inhibitor and antifreeze for your system.
