this rugged component ensures the starting capacitor is dropped out at the exact moment the motor reaches optimal speed

Maxitrol TD121A Selector Els PW 29614 and ultimately drop the millivoltThe Maxitrol TD121A is a precision remote temperature selector engineered for high accuracy atmospheric gas fired heating systems. Designed for use with the Selectra series modulation systems, this component provides a specific setpoint range of 80F to 130F. As a veteran technician knows, maintaining the integrity of the electronic modulation signal is critical; the TD121A ensures stable communication with the amplifier to modulate the gas valve based
