ELECTRIC HEAT Controls

Electric Heat Relays and Contactors • Designed for quiet operation • Use for furnaces with line voltage or pilot duty limit • Simple ON/OFF switching — eliminates cold drafts on system startup • Switches up to four 5kW electric heat elements, plus 7.0A fan motor @ 240VAC • 1/4" male quick-connect • Control voltage 24VAC, current draw 0.23A

• L36-948 has universal mounting plate with mounting screws, two 12" coil leads, two wire nuts, six 1/4" female quick-connects • L36-906 replaces Rheem #R8229A1047 and R8229C1035 (wire only N.O. contacts) • They replace over 50 Honeywell and competitive electric heat primaries, including the Honeywell R8330 Electric Furnace Sequencer

Therm-o-Disc Heat Sequencers • Replaces Klixon, Mars, White-Rodgers, Watsco, Honeywell and Supco • Double quick-connect terminals for combination and heater loads • High ambient rated to +165°F • 24VAC non-positional control • 25A resistive switching • Voltage and ambient self-compensating • Combined fan and heat load ratings (7.2 kW)

• Direct replacements for sequencing both fan and heat • Terminal markings are equivalent to all competitive types and allow one wiring method for various sources of sequencers • May be wired in series to allow sequencing of one through seven element furnaces WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
