Nice Valve Body
Your review: Like this set up with Ra2000 Wall Mt Operator W/Combo Remote Mtd Sensor & Dial. It does not use low voltage like our current valve controls so we are not burning out power heads left & right. Power heads cost $100, this set up costs more initially, but saving money if we had to replace power head more than once.
Pros: Thermostatic control - no low voltage
Cons: Best to change out after or before heating season when lines are drained
