The gateway loses communication with the AC unit. The system will open all its zones and
disable control from the system's thermostats, thus allowing the AC unit to operate from the
manufacturer's thermostat. To resolve this issue, make the following checks:
1.
Check that the AC unit is powered. To do this, check that the AC unit's thermostat is
switched on.
2.
Check whether the AC unit operates properly independently of the system. To do so,
disconnect the AC unit from the Airzone system and activate the unit from the AC unit's
thermostat.
3.
Connections: Check that the polarity of the connections to the gateway and indoor unit is
correct. Consult your gateway's technical fact sheet.
4.
Wired: In DIN rail gateways, check that the voltage between poles (A /-) and (B/-) is 1.8 VDC.
5.
Check that the status of the connected gateway's LEDs is correct. To do so, make use of the
troubleshooting section or your gateway's technical fact sheet.
