1) The letters in the status field indicate the Unit, the # character indicates invalid data.
2) For heating
# = heating option is not available (has not been ordered).
N = heating option is available but have been disabled by user or the heating temperature is
over the high control limit.
V = heating is on at 50% power and the heating temperature is between the high and
middle control limits.
W = heating is on at 100% power and the heating temperature is between the low and
middle control limits.
F = heating is on at 50% power and the heating temperature is below the low control limit.
