• RED wire in control cable damaged or
misconnected.
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
wall control is set. The shortest delay is obtained when the
wall control is set on MIN or MAX in VENT Mode.
• Ensure the RED wire is not damaged and properly connected.

If it does not work, call an electrician.
• Check if fuse F1 (located on the PCB) is blown. In that case, replace
fuse F1 as per product nameplate.
• Check the connection of J10, J9, and J8 connector(s).
• With unit powered and J9 connected, check if there is about
9.5 VAC between transformer connector J8-4 and J8-5 (YELLOW
