Installing the Daikin ENVi Thermostat Kit DRAFT There are 6 steps to installing the Daikin ENVi thermostat kit: Step 1. Power Off the Daikin Indoor Unit WARNING: The Indoor Unit uses a high-voltage 208/230V power source. Always DISCONNECT power to the Indoor Unit before connecting any power wires. Failure to do so can result in death, fire or electrical shock. Step 2.
PAGE 9
Installing the Daikin Power and Communication Adaptor Step 1. Disconnect power to Indoor Unit DRAFT Step 2. The Daikin Power and Communication Adaptor (DPCA) provides an interface between the Thermostat and Indoor Unit. To install the DPCA: PUBLIC 1. Position the DPCA in a suitable location away from water near the Indoor Unit (for example, the backside cavity of a wall-mounted unit). 2. Connect the DCPA power cables to the indoor Unit power supply terminals.

Configuring the Daikin ENVi Thermostat ‐ Preferences The first step after installing the Daikin ENVi thermostat is to configure the thermostat settings for the Indoor Unit. Intelligent Eye: Menu > Settings > Preferences > Intelligent Eye > Yes/No DRAFT  Some models of the Indoor Unit include an intelligent eye, an infrared sensor that detects room occupancy. It adjust the set point by 3.6°F (2°C) if no movement is detected in order to save energy (+3.6°F/+2°C if cooling,-3.6°F/-2°C if heating).
PAGE 18
Configuring the Daikin ENVi Thermostat ‐ Installation Settings Installation Settings: From Home screen select Menu > Settings > Installation Settings Allow Auto Heat/Cool DRAFT  Enabling this option allows the user to select auto change-over as a system mode.  Only visible if the Indoor Unit supports heat or an auxiliary heat source is configured.
PAGE 19
Configuring the Daikin ENVi Thermostat – System Settings System Settings: Menu > Settings > Installation Settings > System Settings DRAFT  Min Cycle Off Time Sets the minimum equipment off time between cool cycles: 240 to 900 seconds (default is 240 seconds).  Min Cycle On Time Sets the minimum equipment run time in cool mode: 1 to 20 min (default is 3 min). PUBLIC  Min Outdoor Temp Disables the compressor when the outside air temperature reaches the configured minimum setting.
PAGE 20
Configuring the Daikin ENVi Thermostat – System Settings (continued) DRAFT  AC Overcool Max When using the AC to dehumidify, the setting configures how many degrees below the current set point the thermostat will run in order to reach the dehumidify set point. Options are Disabled (default) and 0.5 to 3 °F (0.3 to 1.8°C) in 0.5 F (0.3°C) increments.  Heat Differential Temp The minimum difference between the current temperature and set temperature before the system calls for heat.
PAGE 21
Configuring the Daikin ENVi Thermostat – System Settings (continued) DRAFT  Indoor Unit Temp Offset Depending on its type, the Indoor Unit uses a temperature offset for the heating set point, taking into consideration the higher sensing temperature. The Daikin ENVi thermostat applies the offset to the set point which is sent to the Indoor Unit. The offset should be 3.5°F (2.0°C) for wall-mounted and ducted indoor units, and 0°F (0°C) for floor-standing indoor units (available in the future).
PAGE 22
Configuring the Daikin ENVi Thermostat – Installation Settings Aux Heat Settings: Menu > Settings > Installation Settings > Aux Heat Settings  The Aux Heat Settings configure an auxiliary heat source. DRAFT  If you want to test the auxiliary heater during installation, set Aux Heat Installed to Yes and set Allow HP with Aux Heat to No. Then, adjust the heat set point to enable the auxiliary heater.  Aux Heat Installed When set to Yes, configures the thermostat to control an auxiliary heat source.
PAGE 23
Configuring the Daikin ENVi Thermostat – Installation Settings (continued) Fan Configuration: Menu > Settings > Installation Settings > Fan Configuration DRAFT  The Fan Configuration settings map the Indoor Unit’s internal fan speeds to the fan speed options displayed to the user on the thermostat.  Heating Mode Speeds Configures fan speed when the user selects High, Medium or Low while the system is in heat mode. The possible speeds for each value are High, Medium High, Medium, Medium Low, and Low.
PAGE 24
Configuring the Daikin ENVi Thermostat – Installation Settings (continued) Force System Off: Menu > Settings > Installation Settings > Force System Off DRAFT  Force System Off is used to clear a latched system error status in the indoor unit by turning off the equipment for five seconds after system servicing. Operation will automatically resume with the previous settings once complete.
PAGE 25
Configuring the Daikin ENVi Thermostat – Reminders & Alerts Reminders and Alerts: Menu > Reminders and Alerts DRAFT The system service (maintenance) reminder generates an alert telling the homeowner that regularly scheduled maintenance is required. This reminder, along with technician contact information, can be displayed on the screen. If homeowners register their thermostats, the reminders will be emailed to them and be displayed in the web portal.
