During connection of the backup heater, miswiring is possible. To
X14M 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.
Example measure resistance between K1M/1 and K5M/13:
7.8.21
