Resideo TH1100DV1000 Thermostat 328140-751 while the non-spring return design

while the non-spring return design ensures the actuator maintains its last commanded position upon signal termination

minimizing hysteresis and ensuring reliable proportional control in steam or water applications

Faults are often caused by a failing inducer motor

Enhanced Safety: High-performance flame sensing capabilities immediately shut down gas flow if a pilot or main burner failure is detected
