Normal switching between cooling and heating
With CITY MULTI's switchable cooling/heating models, in
order to switch from cooling to heating, the operation
mode of all indoor units performing cooling operation
needs to be switched manually.
Using system changeover to switch between cool-
ing and heating
Depending on the dip switch settings, the operation mode of all
indoor units can be automatically switched according to the
operation mode of a specific indoor unit (the unit with the
smallest M-NET address). Operation can be automatically
switched between cooling and heating according to the
temperature difference between the preset temperature on the
specific indoor unit and the room temperature.
When both cooling and heating operations are required in a single day due to a large difference between the hottest
and coldest times of the day.

all units
and controls them

When using the AE-200E/AE-50E
System changeover (for heat pumps)
• Image of the averaging method
When the temperature sensor
detects a certain differential
between the room temperature
and the set temperature, the
operation of all indoor units in
the system is switched from
heating to cooling.
It is possible to automatically switch between cooling and heating without setting the dip switches on outdoor units. Users
can select from the two types of switching patterns shown below.
(1) Averaging
Operation mode (cooling or heating) is determined and switched every 15 minutes based on the demands of the
majority of all groups connected to the outdoor unit, taking into consideration the capacity of each indoor unit and the
temperature differences between the set temperatures and room temperatures.
(2) Representative Group
Operation mode (cooling or heating) is switched based on the temperature difference between the set temperature
and the room temperature of the representative group.
Set temperature
Room temperature
If the room temperature is higher on average than the set temperature,
AE-200E changes the system mode to cooling.
Cooling mode or heating mode is decided by the average weighted
return air temperature, the set temperature and capacity.
