Start-up troubleshooting:

NOTE: Inspect the unit before proceeding with these steps.

12. Troubleshooting

PROBLEMS POSSIBLES CAUSES YOU SHOULD TRY THIS

1. The error code E1

is displayed on Platinum or

Deco-Touch control screen.

• The wires may be in

reverse position.

• The wires may be broken.

• The wires may have a bad

connection.

• Ensure that the color coded wires have been connected to

their appropriate places.

• Inspect every wire and replace any that are damaged.

• Ensure the wires are correctly connected.

2. There is no outside

temperature displayed on

Platinum control screen

 

• The unit thermistor is defective.

NOTE: At its very start-up or after a power failure, it takes

some minutes before the outside temperature

appears on screen. The delay duration depends on

which operation mode the control is set. The shortest

delay is obtained when the control is set on MIN or

MAX in VENT Mode.

• Replace the thermistor.

3. Platinum or Deco-Touch

control screen alternates

between normal display

and E3.

• The Platinum or Deco-Touch

control is defective.

• Replace the Platinum or Deco-Touch control.

4. On Platinum wall control,

there is an important

difference between

temperature displayed and

real temperature.

• The unit thermistor is defective.

• The unit damper has been

blocked or broken.

• Replace the unit thermistor.

• Check for the proper operation of the unit damper; replace if

necessary.

5. Unit does not work. • The circuit board

may be defective.

• The power cord fuse may

be blown.

• Unplug the unit. Disconnect

the main control and the

optional control(s) (if need be).

Jump B and G terminals.

Plug the unit. If the motor

runs on high speed and the

damper opens, the circuit

board is not defective.

• Unplug the unit. Unscrew the fuse

holder (grey circle on illustration

beside). Check if the fuse is blown

(the strand is broken). If it is blown,

replace the fuse according to the

specifications on the unit power

cord tag.

6. The damper actuator does

not work.

• The 9-pin connector may have

a loose connection.

• The damper actuator may be

defective.

• The circuit board may be defective.

• Unplug the unit and check to make sure all the crimp

connections are secured. Check the damper actuator

connections as well.

• Feed 120 V directly to the damper actuator. If the problem

persists, replace the damper actuator.

• Replace the circuit board if the problem is not solved by the above.

7. The control does not work

OR the indicators flashes

every 8 seconds.

• The wires may be in reverse

position.

• The wires may be broken.

• There may be a short-circuit.

• The wire in the wall OR the

control may be defective.

• The circuit board may be

defective.

• Ensure that the color coded wires have been connected to

their appropriate places.

• Inspect every wire and replace any that are damaged.

• With the help of a multimeter, check for continuity.

• Remove the control and test it right beside the unit using

another shorter wirer. If the control works there, change the

wire. If it does not, change the control.

• If the second control does not solve the problem, then

replace the circuit board.
