Wiring Requirements The Daikin ENVi thermostat uses 4-wire low-voltage cable to connect to the Daikin Power and Communication Adapter (DPCA) which in turn connects to the Indoor Unit. The maximum wire length between the Daikin ENVi thermostat and the DPCA is as follows: 18 AWG: 1250 ft/380 m 20 AWG: 800 ft/240 m 22 AWG: 500 ft/150 m INSTALLING THE THERMOSTAT KIT There are 5 steps to install the Daikin ENVi thermostat kit: Step 1. Power Of the Daikin Indoor Unit Step 2. Position and Wire the DPCA Step 3.
Step 2. Position and Wire the DPCA The Daikin Power and Communication Adapter (DPCA) provides an interface between the thermostat and Indoor Unit. To install the DPCA: 1. Position the DPCA in a suitable location, away from water and near the Indoor Unit (for example, a backside cavity of a wall-mounted unit). The DPCA is not plenum rated and should be mounted in a non-plenum space. 2. Connect the DPCA power cable to the Indoor Unit power supply terminals.
