3-4. Connecting Multiple Indoor Units to a Single Solenoid Valve Kit
It is possible to connect multiple indoor units to one solenoid valve kit.
The indoor units can be controlled individually or be operated as a group.
It is possible to adopt multiple units with a common use of the solenoid valve kit per piece of refrigerant.
Categories of connected indoor unit capacities are determined by the solenoid valve kit.
Type of solenoid valve kit
Total capacity of indoor units
CZ-P160HR2U
19,100 BTU / h (5.6 kW) < Total capacity ≤ 54,600 BTU / h (16.0 kW)
CZ-P56HR2U
Total capacity ≤ 19,100 BTU / h (5.6 kW)
* If the capacity range is exceeded, use two solenoid valves connected in parallel.
