White-Rodgers 1127-2 Hydronic Temperature Control

The White-Rodgers 1127-2 Hydronic Temperature Control is a reliable surface/strap-on temperature control designed for hydronic systems. Perfect for water-based heating, it uses a SPDT switch and offers a wide 100–240°F range to fit radiant and baseboard installations.

Engineered for versatility in a hydronic system, this control provides safe operation with full-load ratings of 7.4 Amp at 120V AC and 3.7 Amp at 240V AC (120/240 Volt input).
