2.4.1.2 - 230VCA
Make sure the line voltage selector switch is set to
230VAC
. Connect the power cable to terminals 3 and 4 on
the main (bottom) board.
2.4.2 - Mist output (terminals 5 and 6)
The relay can drive a load of 10 Amp maximum.
2.5 TEMPERATURE PROBES
The temperature probes use a low-voltage class 2 circuit.
The cables (AWG#18 min) can be up to 500 feet (150
meters) in length. For cables longer than 10 feet (3 meters)
use an aluminium-shielded wire which must be connected
to the common of the input power. Temperature probe
connections are illustrated in figure 2 whereas connections
for temperature probe averaging are shown in figure 3.
2.5.1 - Single temperature probe
Install the temperature probe in a location that best reflects
the overall room temperature. Connect the two leads and
the shield of the probe to the terminals labelled “Probe” as
indicate in figure 2.
2.5.2 - Averaging (optional)
Four temperature probes are required to do temperature
averaging in larger rooms. Place the probes in appropriate
locations to best average the room temperature. Refer to
figure 3.
Install low voltage wires (probes, computer link or
potentiometer wires) at least 12 inches (30 cm) away from
high voltage wires (120/230VAC, 24VDC). Always cross
high and low voltage wires at a 90-degree angle.
