Notes on System Design

• The input water temperature to the Hydro Unit must be 55°C or less. Especially, be careful when there is an external heating source such as a boiler. When hot water over 55°C returns, it may result in a failure of the unit or water leakage.

• The flow rate of the circulating water must meet the following range:-

11 and 14 kW 17.5 L/minute or more 8 kW 13 L/minute or more

If the flow rate becomes less than the minimum, the protective device is activated to stop operation. Ensure the flow rate with a bypass valve, etc. when you use a flow rate valve for the Hydro Unit.

• Do not drive water by power other than the pump built in the Hydro Unit.

• The backup heater operates supplementary to exert a prescribed capacity when the heat pump cannot exert its capacity at a low outside temperature.

• Install the Hydro Unit and water pipes in a place in which they do not freeze.

• Make the water circuit closed. Never use it as an open circuit.

• To prevent damage to the system during outdoor defrost the circulating water must be 20 litres or more. If total water amount is not enough, the unit may not function fully due to protective

operation.

Water Piping

• Install water pipes according to the regulations of respective countries.

• Install water pipes in a freeze-free place.

• Make sure that water pipes have sufficient pressure resistance (The setting value of the pressure relief valve is 0.3 MPa).

• Do not use zinc plated water pipes. When steel pipes are used, insulate both ends of the pipes.

Water Connections

• Install a strainer with 30 to 40 meshes (procure locally) at

the water inlet of the Hydro Unit.

• Install drain cocks (procure locally) for water charge and

discharge at the lower part of the Hydro Unit.

Water Piping Limitations

Design the water pipe length within the QH characteristics of the pump (flow-rate and pump head).

The maximum height difference for the water pipes i 7 metres.

Piping to hot water tank (option

Water supplied to the hot water cylinder is branched by a motorized 3-way valve (procured locally). Connect the hot water cylinder to port A (open when energized) of the valve.

)

Piping to 2-zone operation (option)

To perform 2-zone temperature control circulate water using another pump (procured locally) through a motorized mixing valve (procured locally) and a buffer tank (procured locally).

Checking water volume and initial pressure of expansion vessel

The expansion vessel of the Hydro Unit has a capacity of 12 litres. The initial pressure of the expansion vessel is 0.1 MPa (1 bar). The suggested initial water charge is 0.2MPa (2 bar). The pressure of the safety valve is 0.3 MPa (3 bar). Verify whether the capacity of the expansion vessel is sufficient using the following expression. If the volume is insufficient, install an appropriate external expansion vessel.

V Action

< 12 L Internal Expansion Vessel Size OK

> 12 L

Internal Expansion Vessel Size too small.

Install appropriate external expansion vessel

V: Necessary total vessel capacity (L)

Ɛ: Water expansion coefficient at average hot water temperature Vs: Total water volume in the closed system (Do not include Hot Water Cylinder) P1: System pressure at tank setting position (Mpa_abs*).

(Pipe inner pressure during pump operation before heating device operates = water supply pressure)

P2: Maximum pressure used during operation at tank setting position (MPa_abs*).

(= safety valve setting pressure)

* The absolute pressure value (abs.) is obtained by adding the atmospheric pressure (0.1 MPa (1 bar)) to the gauge pressure.

Quick Reference Guide - Page 11

Pump operation / configuration

Change Pump speed, so that water flow is always greater than the minimum flow rate. If water flow

is lower than the minimum rate during operation, the unit detects error.

Water charging

Charge water until the pressure gauge shows 0.2 MPa (2 bar). Hydraulic pressure may drop when the trial run begins. In that case, add water.

Air may enter if the charged hydraulic pressure is low. Loosen the purge valve cap by two turns to release air. Loosen the cap of the pressure relief valve to release air. Water may come out of the pressure relief valve. Release the air completely from the water circuit. Failure to do so may disable correct operation.

Water quality

The water used must satisfy EN directive 98/83 EC.

Piping insulation

It is recommended that insulation treatment be applied to all pipes. To perform optional cooling operation, apply insulation treatment of 20 t or more to all pipes.

Settings by Purpose

Settings when hot water supply function is not used

• When the hot water supply function is not used, set DIP SW12-1 on the Hydro Unit board to ON.

Setting for cooling

• For Space Conditioning Units that do not perform cooling (radiators and Under floor heating, etc.), procure a motorized 2-way valve (for cooling) locally and attach it to the water pipe that is not used for cooling. Connect the valve cables (as described in Electrical section).

• Press long the TEST + SET + SELECT switches on the remote controller to change the Hydro Unit function code, and change address 02 to 0, and then press the SET button to enable the function.

Press the TEST button to exit the setting mode.

• Stick the optional insulator for cooling to the bottom of the Hydro Unit.

Settings for hot water supply

• Prepare the optional hot water cylinder.

• Procure a motorized 3-way (diverter) valve locally and perform piping. Connect the valve cables (as described in Electrical section).

• Set DIP SW12-1 on the Hydro Unit board to OFF.

• Connect the power supply unit for the hot water cylinder heater to terminals TB03 L and N of the Hydro Unit.

• Connect cables between the Hydro Unit and the hot water cylinder as follows: Hydro Unit terminals TB03 (1), (2), and earth — Hot water cylinder (1), (2), and earth

TB06 A, B, and earth — Hot water cylinder A, B, and earth

Quick Reference Guide - Page 27

Settings by Purpose (cont)

Settings for 2-zone temperature control

• Procure a motorized mixing valve locally and perform piping. Connect the valve cables (as described in Electrical section).

• Procure a buffer tank locally.

• Procure a water pump locally, and connect its cables (as described in Electrical section). To inhibit interlocking the water pump with the internal pump of the Hydro Unit, set DIP SW10-3 on the Hydro Unit board to OFF.

• Set DIP SW12-3 on the Hydro Unit board to ON. Attach the temperature sensor (TFI) connected to terminals TB06 C and D of the Hydro Unit near the hot water inlet of the Hydro Unit.

• Contact the temperature sensor closely with the pipe, fix it with aluminium tape or the like, and then perform insulation treatment for the sensor.

• Fix TFI sensor on the room heating supply pipe by using the connector procured in locally.

• Cover the cables with insulation tube (minimum 1 mm) or conduit so that the user cannot touch them directly.

• Connect the functional earth wire of TFI sensor in the tank unit.

• Cover the TFI sensor's cables and sensor with insulation tube (minimum 1 mm) shown in the diagram on the right.

Test Run

Use operation buttons usually to conduct a test run.

If the outside air temperature or water temperature is outside the setting value range, press the TEST button on the remote controller and then start a test run. Since the protection setting is disabled in the TEST mode, do not continue a test run longer than 10 minutes.

• Press the TEST button on the remote controller. An indication “TEST” appears on the remote controller.

• Press the ZONE1, 2 The pump is activated in 30 seconds. If air is not released completely, the flow rate switch is activated to stop operation. Release air again according to the piping procedure. Little air bite is discharged from the purge valve.

• Check that the air bite sound disappears.

• Check that the hydraulic pressure has become the predetermined pressure 0.1 to 0.2 MPa (1 to 2 bar). If the hydraulic pressure is insufficient, replenish water.

• Heating operation starts. Check that the hydro unit starts heating.

• Press the OPERATE MODE

• Cooling operation starts. Check that the hydro unit starts cooling and that the floor heating system is not cooled.

• Press the ZONE1, 2

• Press the HOT WATER

• Check that there is no air bite.

• Check that hot water is present at the connection port of the hot water cylinder.
