1 General safety precautions WARNING NOTICE Tear apart and throw away plastic packaging bags so that nobody, especially children, can play with them. Possible risk: suffocation. Make sure the field piping and connections are not subjected to stress. WARNING DANGER: RISK OF BURNING ▪ Do NOT touch the refrigerant piping, water piping or internal parts during and immediately after operation. It could be too hot or too cold. Give it time to return to normal temperature.
2 About the documentation ▪ Open refrigerant cylinders slowly. WARNING ▪ Charge the refrigerant in liquid form. Adding it in gas form may prevent normal operation. ▪ ONLY use copper wires. ▪ All field wiring must be performed in accordance with the wiring diagram supplied with the product. CAUTION ▪ NEVER squeeze bundled cables and make sure they do not come in contact with the piping and sharp edges. Make sure no external pressure is applied to the terminal connections.

5 Application guidelines Digital I/O PCB (EKRP1HB) The digital I/O PCB is required to provide following signals: 5 Application guidelines 5.1 Overview: Application guidelines ▪ Alarm output ▪ Space heating On/OFF output ▪ Changeover to external heat source For installation instructions, see the installation manual of the digital I/O PCB and addendum book for optional equipment. The purpose of the application guidelines is to give a glance of the possibilities of the Daikin heat pump system.
5 Application guidelines 5.2.1 ▪ Easy. You can easily set the desired room temperature via the user interface: Single room Under floor heating or radiators – Wired room thermostat Setup ▪ For your daily needs, you can use preset values and schedules.
5 Application guidelines Heat pump convectors 5.2.2 Setup If only one leaving water temperature zone is needed because the design leaving water temperature of all heat emitters is the same, you do NOT need a mixing valve station (cost effective). Multiple rooms – One LWT zone Example: If the heat pump system is used to heat up one floor where all the rooms have the same heat emitters.
5 Application guidelines Benefits Heat pump convectors ▪ Cost effective. Setup ▪ Easy. Same installation as for one room, but with thermostatic valves. Under floor heating or radiators – Multiple external room thermostats A B C Setup A B C M1 M2 a a b a a A B C a Main leaving water temperature zone Room 1 Room 2 Remote controller of the heat pump convectors ▪ The desired room temperature is set via the remote controller of the heat pump convectors.
5 Application guidelines Combination: Under floor heating + Heat pump convectors Setup 5.2.3 Multiple rooms – Two LWT zones If the heat emitters selected for each room are designed for different leaving water temperatures, you can use different leaving water temperature zones (maximum 2).
5 Application guidelines ▪ For the main zone: ▪ Efficiency. ▪ A mixing valve station is installed before the under floor heating. ▪ The pump of the mixing valve station is controlled by the ON/ OFF signal on the indoor unit (X2M/5 and X2M/7; normal closed shutoff valve output). ▪ The room temperature is controlled by the user interface, which is used as room thermostat.
5 Application guidelines NOTICE NOTICE ▪ Make sure the auxiliary boiler and its integration in the system complies with applicable legislation. ▪ Make sure the auxiliary contact has enough differential or time delay to prevent frequent changeover between indoor unit and auxiliary boiler. ▪ Daikin is NOT responsible for incorrect or unsafe situations in the auxiliary boiler system.
5 Application guidelines 5.4.2 Selecting the desired temperature for the DHW tank People experience water as hot when its temperature is 40°C. Therefore, the DHW consumption is always expressed as equivalent hot water volume at 40°C. However, you can set the DHW tank temperature at a higher temperature (example: 53°C), which is then mixed with cold water (example: 15°C).
5 Application guidelines 5.4.5 DHW pump for disinfection Setup 5.5.2 Consumed energy Measuring the consumed energy ▪ Requires external power meters. g ▪ Setup and configuration: b h c e d f a a b c d e f g h DHW tank DHW pump Heater element Nonreturn valve Shower Cold water Domestic hot water OUT Recirculation connection ▪ The DHW pump and the installation are field supply and the responsibility of the installer.
5 Application guidelines 5.5.4 Preferential kWh rate power supply NOTICE Set a minimum power consumption of ±3 kW to guarantee space heating and DHW production by allowing at least backup heater step 1. Setup ▪ Connect power meter 1 to X5M/7 and X5M/8. ▪ Connect power meter 2 to X5M/9 and X5M/10. Refer to "6.4.3 Overview of electrical connections except external actuators" on page 23. 5.
6 Preparation INFORMATION In case more than 1 digital input is closed (at the same time), the digital input priority is fixed: DI4 priority>…>DI1. 5.6.3 Power limitation process The compressor has better efficiency than the electrical heater. Therefore, the electrical heater is limited and turned OFF first. The system limits power consumption in the following order: 1 Limits electrical heater. 2 Turn OFF the electrical heater. 3 Limits the compressor. 4 Turns OFF the compressor. Preparation 6.
6 Preparation 6.3 Preparing piping 6.3.1 Circuit requirements INFORMATION Also read the precautions and requirements in the "General safety precautions" chapter. Circuit types. Except for the refrigerant circuit, inside the unit 2 other circuits are included. For future references: the circuit connected to the bore hole is referred to as the brine circuit, the other circuit connected to the heating emitters is referred to as the space heating circuit. ▪ Fluid pressure – Domestic hot water tank.
6 Preparation ▪ Air vents. Provide air vents at all high points of the system, which must also be easily accessible for servicing. At the space heating side, an automatic air purge is provided in the indoor unit. Check that the air purge is NOT tightened too much, so that automatic release of air in the water circuit is possible. ▪ Zncoated parts. NEVER use Zncoated parts in the fluid circuit. Because the unit's internal circuit uses copper piping, excessive corrosion may occur.
