Special remark for terminals:
As mentioned on the table above, the connections on the terminals
X6M and X7M need to be changed to configure a backup heater.
Refer to the illustration below as a caution about handling the
terminals.
3 Fix the cable with cable ties to the cable tie mountings.
INFORMATION
For more information on the backup heater types, and for
how to configure the backup heater, refer to the
"Configuration" chapter of the installation manual of the
outdoor unit.
During connection of the backup heater, miswiring is possible. To
detect possible miswiring on the *9W model, it is highly
recommended to measure the resistance value of the heater
elements. Depending on the different backup heater types, following
resistance values (see table below) should be measured. ALWAYS
measure the resistance on the contactor clamps K1M, K2M, and
K5M.
