Maxitrol TD121B Temperature Selector Els PW 29614 For technicians optimizing flame retentionThe Maxitrol TD121B Temperature Selector is a critical component for Selectra Series 21 and 31 electronic gas flame modulation systems. Specifically engineered for indirect fired make up air units, this remote selector provides precise setpoint control within a 120 170F temperature range. For a stable discharge air temperature, it must be paired with a TS121B sensor to ensure the resistance curves match the A1010 or A1011 amplifier logic. This
