Recommended Systems
1. System with a remote sensor connected to each indoor unit
On the ceiling chamber system with which generated heat loads are treated in the ceiling space, the suction
thermistor (body thermistor) mounted to the indoor unit alone cannot ensure the detection of room temperatures.
Consequently, for the indoor unit, in order to ensure the detection of the room temperatures, it is recommended to
change to the remote sensor system.
2. Connection of refrigerant piping
For the connection of refrigerant piping on the ceiling chamber system, it is recommended to provide a system
preventing the cool-heat changeover while in automatic mode on the VKM through connecting a base indoor unit in
the same duct system and the VKM to the same BS unit to interlock between the VKM and the indoor unit (*).
* In order to interlock between the VKM and the indoor unit, the group control of remote controllers should be
provided.
Fig. 1 When interlocking between the base indoor unit and the VKM:
(Connect multiple indoor units and VKM to a single BS unit.)
Fig. 2 When connecting a single indoor unit or a single VKM to a single BS unit:
(If this is the case, use the VKM in fixed cooling or heating mode.)
3. Measures against inadequate humidification
When operating the system at a temperature in the ceiling space set higher than the initial setting, the heating
thermostat on the VKM may turn OFF to disable humidification. In this case, according to the field setting on the
remote controller, raise the heating set temperature. For details, refer to information on page 85.
