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 Off 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.

The mounting holes can accommodate a #6 pan-head screw. It is recommended to use the included fasteners to ensure proper fitting of the front housing. 5. Use the included drywall plugs (or other suitable anchors) to ensure the thermostat can be mounted securely to the wall. 6.
Step 4. Connect the Thermostat Wiring Use the field-supplied 4-wire low-voltage cable to connect the thermostat to the DPCA. To connect the thermostat to the DPCA: 1. Connect the wires as shown: P1 Terminal on DPCA Optional Auxiliary Heater DD+ 24VAC C C R Daikin ENVi Thermostat D- D+ C R AUX AUX R 2. Attach the Daikin ENVi thermostat to the backplate. Ensure that the pins on the thermostat align with the terminal block on the backplate.
Step 5. Mount the DPCA After you make the necessary wiring connections, mount the DPCA by using the adhesive sticker or mounting screws as needed. Step 6. Power On Daikin Indoor Unit After you’ve completed the wiring, you can apply power to the Daikin Indoor Unit. The Daikin ENVi thermostat receives power from the equipment and will automatically power on. After you power on the Indoor Unit: 1. Verify the green LED on the DPCA has turned on. Upon verification, re-attach the DPCA cover. 2.
