(B) In case of stacked installation Drain work 1. In case obstacles exist in front of the outlet side. Check in the combination table under "Possible options" on page 3 whether drain work is allowed. In case drain work on your unit is allowed and the installation site requires drain work, then follow the guidelines below. Drain kits for drainage are available as option.
TYPICAL APPLICATION EXAMPLES Application 2 When the AD system is used in series with another heat source (e.g. gas boiler), it shall be made sure that the return water temperature to the heat exchanger does not exceed 55°C. Daikin shall not be held liable for any damage resulting from not observing this rule. Space heating only application without room thermostat connected to the unit. The temperature in each room is controlled by a valve on each water circuit.
Domestic water heating Pump operation and space heating and cooling When domestic water heating mode is enabled (either manually by the user, or automatically through a schedule timer) the target domestic hot water temperature will be achieved by a combination of the heat exchanger coil and the electrical booster heater. According to the season, the customer will select cooling or heating on the room thermostat (T). This selection is not possible by operating the user interface.
Pump operation With no thermostat connected to the unit (1), the pump (3) can be configured to operate either as long as the unit is on, or until the required water temperature is reached. Details on pump configuration can be found under "Pump operation configuration" on page 19. NOTE Main components Hydraulic compartment (door 3) 1 19 Space heating and cooling 16 According to the season, the customer will select cooling or heating through the user interface.

Wiring the 3-way valve Possible types of benefit kWh rate power supply 1 Possible connections and requirements to connect the equipment to such power supply are illustrated in the figure below: Using the appropriate cable, connect the valve control cable to the appropriate terminals as shown on the wiring diagram. [D-01]=1 Two types of 3-way valves can be connected.
3 Benefit kWh rate power supplies that completely shut power supply like illustrated above as types 2 and 3 are not allowed for this application because of the water freeze prevention that would not be powered. ■ When connecting the equipment to a benefit kWh rate power supply, change field settings [D-01] and both [D-01] and [D-00] in case the benefit kWh rate power supply is of the type that power supply is not interrupted (like illustrated above as type 1).
START-UP AND CONFIGURATION The unit should be configured by the installer to match the installation environment (outdoor climate, installed options, etc.) and user expertise. It is important that all information in this chapter is read sequentially by the installer and that the system is configured as applicable. DIP switch settings overview The following table summarizes the required configuration and thermostat wiring at the terminal block in the switch box.
8 Domestic hot water tank installation configuration Refrigerant leak ■ When no domestic hot water tank is installed, toggle switch SS2-2 should be set to OFF (default). OFF ON ■ When a domestic hot water tank is installed, toggle switch SS2-2 should be set to ON. OFF ON Check the inside of the unit on refrigerant leakage. If there is a refrigerant leak, call your local dealer. 1 2 1 2 3 4 9 Power supply voltage Check the power supply voltage on the local supply panel.
Failure diagnosis at the moment of first installation Field settings ■ The unit should be configured by the installer to match the installation environment (outdoor climate, installed options, etc.) and user demand. Thereto, a number of so called field settings are available. These field settings are accessible and programmable through the user interface.
Detailed description [2] Disinfection function [0] User permission level Applies only to installations with a domestic hot water tank. If required, certain user interface buttons can be made unavailable for the user. The disinfection function disinfects the domestic hot water tank by periodically heating the domestic water to a specific temperature. Three permission levels are defined (see the table below).
[4] Backup heater operation and space heating off temperature Backup heater operation The operation of the backup heater can altogether be enabled or disabled, or it can be disabled depending on operation of the booster heater. ■ [4-00] Status: defines whether backup heater operation is enabled (1) or disabled (0). NOTE Even in case the backup heater operation status field setting [4-00] is set to disabled (0), the backup heater can operate during start-up and defrost operation.
[6] DT for domestic water heating [7] Domestic hot water step length Applies only to installations with a domestic hot water tank. Applies only to installations with a domestic hot water tank. The 'DT (delta temperature) for domestic water heating' field settings determine the temperatures at which heating of the domestic water by the heat pump will be started (i.e., the heat pump ON temperature) and stopped (i.e., the heat pump OFF temperature).
[8] Domestic water heating mode timer Applies only to installations with a domestic hot water tank. ■ [8-03] Booster heater delay time: specifies the start-up time delay of the booster heater operation after start of the heat pump domestic water heating operation. The 'domestic water heating mode timer' field settings defines the minimum and maximum domestic water heating times, and minimum time between two domestic water heating cycli.
[9] Cooling and heating set points [D] Benefit kWh rate power supply The purpose of this field setting is to prevent the user from selecting a wrong (i.e., too hot or too cold) leaving water temperature. Thereto the heating temperature set point range and the cooling temperature set point range available to the user can be configured.
