PLENUM TEMPERA TURE
SENSOR MOUNTING
The plenum temperature sensor is
the white PVC junction box with bolt
extending from outside attached by
a cord to the fan/heater control box.
1. 24" to the right side of the transition, drill one 3/8" hole in the center of the plenum in a valley on
the bin sidewall.
2. Insert the probe through the hole.
3. Position the housing so that the
tabs are vertical, and the cord
exits the housing horizontally.
SERIES TWO HEATER
4. Use two self drilling screws to mount
the housing to the bin sidewall.
5. Caulk between the housing and
the sidewall to seal.
TRANSITION HI-LIMIT INSTALLATION
1. Mark location on transition one
(1) foot up from the bottom
(entrance collar) and centered
in the transition.
2. Drill or knock out 7/8" diameter
hole on marked location.
3. Install transition hi-limit using
supplied self drilling screws.

WIRING
HEA TER UNIT
1. Be sure fan unit is installed and wired to meet local
codes. Be sure equipment is well grounded (see page 9).
2. A separate neutral is required for 120 volt heater
circuit in 220 volt 1PH and 3PH fan units. For 460 volt
fan units a separate 120 volt power supply or transformer
is required.
3. Run S-wire black cord from heater unit to fan unit
and secure to fan.
HEATER INST ALLATION
4. Orange and red wires should be connected in series
with coil in fan. When contacts in heater between these
wires open fan shuts down. Recommended wiring is
shown in Figure 2.
5. Black and white wires should be connected to a fused
Figure 2: Wiring diagram for the fan and heater unit.
120V power supply as shown. Green wire should be connected to ground in fan.
Figure 3: Secondary heater wiring diagram.
SECONDARY
HEA TER UNIT
1. Secondary heater unit runs as a slave of heater unit
#1 and re-quires no plenum or grain temperature sensor.
2. Run (2) 20 gauge (minimum) wires from secondary
heater unit (slave) to heater unit #1 (master).
3.
Connect wires as shown in Figure 3.
4. Third heater unit may also be added to system. If
adding third unit, run connections to master unit #1 and
connect them inparallel with secondary heater unit.
