Panasonic’s range of 3-way heat-recovery control boxes for VRV air-conditioning systems is available with four, six and eight connection ports to give installers considerable flexibility on site. These control boxes have connection tubes for the main refrigerant circuit line on both sides of the unit

These control boxes remove the need for purchasing individual 3-way PCB kits and solenoid valves for each indoor unit. A control line can be fed from the unit via a relay kit, which is included in the package as an accessory, straight to the multiple-connection box. A power line is then fed directly form the multiple-connection box to the power supply, so there is no need for a power supply from each indoor unit to each individual solenoid valve kit.

The 3-way control box can be installed after a distribution joint, before a T branch and with a number of different control methods — such as group control, simultaneous operation under one port and group operation under one port.
