BROODER CONTROL OPTIONS
Control No. 2A/2B For single or multi-zone installations using central or multiple thermostats. This 24-
volt, AC, zone-type control also can operate on DC voltage as a back up. The gas
valve includes a built-in regulator. A 24-volt power supply is required. Brooder can
be operated by a 24-volt thermostat, computer or an environmental controller.
100% gas safety shut-off valve.
Control No. 3
A modulating type HI/LO control with integral thermostat. No electrical supply is
needed. Upon call for heat, the valve will open from pilot to low fire (approximately
22,000 Btu/hr) and modulate between low and high fire (30,000 Btu/hr) as
necessary to maintain desired temperature setting. As the thermostat is being
satisfied, the valve will modulate down to low fire and then drop to pilot upon being
satisfied. 100% gas safety shut-off valve.
Control No. 5B/5D Designed for single or multi-zone installations using one or more thermostats. A
zone control (available as an accessory, Part #43619050) is required to provide a
24-volt power supply to each brooder. The burner is controlled with a Direct Spark
Ignition (DSI) module, which is designed to provide 100 percent gas shut off of the
main valve in the event that the main burner lame is not sensed.
Control No. 9 An individual, non-electric, fully automatic ON/OFF control with integral thermostat,
which operates on milivolts generated by the pilot. No electrical supply is needed.
Integral thermostat features a wide temperature range for easy adjustment. 100%
gas safety shut-off valve.

BROODER ACCESSORIES
A)
Zone Control Panel Model ZCP22, Part #43619050
This is a power supply control which utilizes a 375VA
transformer to provide the required 24VAC for single or
multiple groups (zones) of No. 2A or 5B brooders. Refer to
electrical section of manual for allowable heater quantities per
transformer.
Use power inverter kit #43619070 for battery back-up.
B)
Power Inverter Kit (for battery back-up), Part #43619070 (Not Shown)
This provides temporary 120VAC to the brooder zone control (power supply) panel during
power outages. The kit includes a battery trickle charger, changeover relay and power
inverter to convert 12 volt DC into 120 volt AC. (For No. 5B brooders only.)
C)
Transformer Replacement – 375VA 120/240VAC – 24VAC,
Part #30222070
D)
