2 LOWTW Condensation warning, indicates that the inverter (water)
temperature is lower than expected – possible causes
include inverter water valve stuck open.
1 HIGHTW Indicates that the inverter temperature is higher than
expected – possible causes include no or low cooling water
flow, inverter water valve stuck closed or water pipe to
inverter blocked.
