PROBLEMS POSSIBLE CAUSES YOU SOULD TRY THIS
1
The error code E01 is
displayed on VT9W wall
control screen.
• The wires may be in reverse position.
• The wires may be misconnected.
• The wires may be broken.
• Ensure that the color coded wires have been connected to
their appropriate places.
• Ensure the wires are correctly connected.
• Inspect every wire and replace any damaged ones. If wires
are hidden into walls, test the control using a shorter wire.
2
The VT9W wall control
screen alternates between
normal display and E03.
• The VT9W wall control may be
defective.
• Replace the VT9W wall control.
3
The VT9W wall control
does not work.
• Wrong main control.
• The wires may be in reverse position.
• The wires may be misconnected.
• The wires may be broke.
• Defective wall control.
• Ensure the main control is an VT9W.
• Ensure that the color coded wires have been connected to
their appropriate places.
• Ensure the wires are correctly connected.
• Inspect every wire and replace any damaged ones. If wires
are hidden into walls, test the control using a shorter wire.
• Replace the wall control.
4 Unit does not work.
• Unit is unplugged.
• No power to power outlet.
• The fuse may be defective.
• J10, J9, or J8 connector(s) may be
unplugged.
• The transformer may be defective
(no 9.5 VAC between J8-4 and J8-5).
•
The main PCB may be defective.
• Make sure the unit is plugged.
• Test the power outlet with another electrical device (e.g.: a
lamp). If it does not work, call an electrician.
• Unplug the product from the outlet. Check if fuse F1 (located
on the PCB) is blown. In that case, discontinue using the
unit and contact technical support.
• Check the connection of J10, J9, and J8 connectors.
• With unit powered on and J9 connected, check if there is
about 9.5 VAC between J8-4 and J8-5 (YELLOW wires)
transformer connector. If not, change the transformer.
• Replace the main PCB.
5
The VB60W push-button
timer does not work (unit
LED lit, no matter the
color).
• The wires may be in reverse postion.
• The wires may be misconnected.
• The wires may be broken.
• The push button may be defective.
• Ensure that the color coded wires have been connected to
their appropriate places.
• Ensure the wires are correctly connected.
• Inspect every wire and replace any damaged ones. If wires
are hidden into walls, test the control using a shorter wire.
6
Unit is always on high
speed.
• The VB60W push-button timer wires
may be shorted.
• Ensure OC and OL wires do not touch each others.
• Unplug wires from the auxiliary control terminal block and
measure the resistance between cables (there should be
no resistance). If resistance has been detected, ensure the
wires are correctly connected, then inspect every wire and
replace damaged ones.
• Jump the OL and OC terminals. If the unit
switches to high speed, remove the push
button and test it right beside the unit
using another shorter wire. If it works here,
change the wire. If it doesn’t, change the
push button.
