AC Unit ▬► AC unit control
When the system is set for zone control by the installer the temperature for the respective zones must be modified
through the 'Zones' icon (AC Unit -> Zones). The below configuration is set for zone control and will display the
zone with the coldest setpoint in 'Cool' mode and warmest setpoint in 'Heat' mode. The Cool mode example below
show cases the zone with the greatest cooling demand or setpoint temperature, that being Zone 2 at 20.0°C.
The temperature section displaying 'Normal 20.8°C' is the temperature measured at the controlling zone actual
temperature sensor of the AC's fan coil unit� This temperature may not be visible if not enabled during installation�
When set for zone control the only functions that may be modified are the 'Mode' and 'Fan Speed'.

NOTE

MODE CONTROL

The Rinnai Home system has the following modes to select:

Cool

The AC unit will be run in Cool / Cooling mode.
The compressor will be controlled by the AC Unit's own protocol.
The fan will run in the AC units factory default setting (continuously or cycle with the compressor) or as set up in
the AC unit field settings. For best results we recommend the supply air fan runs continuously in Cool Mode.

Heat

The AC unit will be run in Heat / Heating mode.
The compressor will be controlled by the AC Unit's own protocol and will initiate defrost mode as required by the
condensing unit�
The fan will run in the AC units factory default setting (continuously or cycle with the compressor) or as set up in the
AC unit field settings. For the best results we recommend the supply air fan cycles on and off with the compressor
in Heat Mode�

Vent

In Vent mode the fan will run continuously and the compressor will not start.
