CAUTION

Standard type ESTIA units and Powerful type ESTIA units are not compatible with one another. When selecting your ESTIA system please ensure that you select all units from the either the Standard type model list or the Powerful type model list shown above.

DO NOT DESIGN YOUR SYSTEM USING A MIX OF STANDARD TYPE UNITS AND

POWERFUL TYPE UNITS

Note:

Under floor heating components, fan coil units, radiators, valves and other installation materials must be procured locally.

Notes on System Design

• The input water temperature to the hydro unit must be 50°C or less for ESTIA Series 4 Standard type and

55°C or less for ESTIA Series 4 Powerful type

. This is especially important if the hydro unit is used in conjunction with any other external heating source

(auxiliary boiler, electric booster heaters etc.)

Unit failure or water leaks may result if the return water temperature, to the hydro unit, exceeds the recommended inlet water temperatures shown above

• The minimum flow rate for the circulating water in the heating/cooling circuit must meet the following range:-

11, 14 and 16 kW: 17.5 L/minute or more

8 kW: 13 L/minute or more

If the flow rate becomes less than the flow rate specified above, the flow switch in the hydro unit is activated to stop operation.

When thermostatic devices are used for temperature control a bypass valve must be fitted to the heating circuit, to ensure the minimum water flow rate is maintained in the event of all thermostatic devices closing at the same time

• Only use the water pump, built into the hydro unit, to circulate the water in the heating circuit

• The hydro unit back up heaters will operate to assist the heat pump capacity output during low ambient conditions

• The hydro unit has been designed for indoor installations. Do not install outside where there is a risk of low ambient conditions. This may cause the water in the pipe work to freeze

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

• To prevent damage to the system the volume of the circulating water must be 20 litres or more. If total volume of water amount is less than 20 litres, then the unit may not function fully due to the operation of protective controls.

Installation Examples

Cooling and Heating with Domestic Hot Water

When both cooling and heating are used, install a 2-way valve (for cooling) to the pipe to the room for heating only.

3

Installation Examples (cont.)

2-Zone Temperature Control with Domestic Hot Water

The following shows an example of the 2-zone temperature control.

A buffer tank and a water pump are required for the 2-zone temperature control. This example is Heating only, if the Fan Coils are to be used for Cooling then a 2-Way valve must be fitted.

4

Installation example of water circuit:-

(1) (2)

(3) (4)

(5) (6)

The water circuit for a system without a buffer tank [ (1) , (2) , (3) , (5) ] requires 17.5l/min (804XWH =

13.0l/min) or more. This water flowing requires 5 or more branches of Floor heating or Radiators etc.

Less than 5 branches may cause a flow deficiency. In this case, please provide a buffer tank and secondary pumps, as shown in (4).

Please check how to install the boiler.

Water Piping

WARNING

• Ensure that the heating circuit, and all components of the heating circuit, are installed in accordance with all National and local regulations

• The water pipes must not be installed where they are exposed to low ambient air temperatures. This is to prevent the water freezing in the pipes

• Make sure that water pipes have sufficient pressure resistance

(The setting value of the pressure relief valve is 0.3 MPa).

CAUTION

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

• The water to be used must meet the water quality standards specified in EN directive 98/83 EC.

Water Circuit

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

• The ESTIA system can only be used on pressurised heating circuits. If the system is used on gravity fed heating circuits then system failure may occur

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 is 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.

11

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 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.

Water charging

Charge the water, in the heating circuit, until the pressure gauge shows 0.2 MPa (2 bar).

The hydraulic pressure may drop when the trial run begins. In this case, add water until the hydraulic pressure returns to 0.2MPa (2 bar)

Air may enter the heating circuit if the hydraulic pressure is low.

Air purge

Loosen the Air relief valve cap by two turns to release air (see diagram):

Either Type A or Type B automatic air purge valve will be fitted to the hydro unit. Type B purge valve cap faces the front as factory standard.

Ensure all air is removed from the system. If air remains in the system then the system operation may

STOP.

14

Loosen the air vent screw on the hydro unit water pump to ensure all the air has been removed from the pump housing. Tighten the air vent screw on completion of the air purge.

Manually operate the pressure relief valve fitted to the hydro unit to release any air that may be trapped in the pressure relief valve pipe (water may be released from the pressure relief valve during this operation).

Note: Due to the design of the electrical back up heater it is not recommended to add any corrosion inhibitors / additives to the heating circuit.

Water quality

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

Piping insulation

It is recommended that insulation is fitted to all pipes. To perform optional cooling operation, apply insulation with a rating of 20t or more to all pipes.

Connect the external hot water cylinder thermostat (S1 in the diagram below) to terminals 2 (COOL) and

3 (COM) on the option PCB.

When the hot water cylinder thermostat contact, S1, is CLOSED then there is a hot water demand and the system will produce hot water (if all DPSW’s and function codes are set correctly)

26

External system STOP:

Connect the external STOP signal / contact (S2 in the diagram above) to terminals 1 (HEAT) and 3 (COM) on the option PCB.

It is possible to set the operating logic of contact S2 (normally OPEN contact, normally CLOSED contact or pulse input) using function code FC52 and the operating mode of the system, on restart, using FC61 (see function code list on page 31 for options).

The external stop option can also be used for TEMPO control where an external signal, from the customers electricity measuring meter, is applied to the option PCB (contact S2 connections). TEMPO control can be used as part of the price contract provided by French electric power company EDF. The TEMPO control options are set using FC61.

ESTIA - System Set Up

Please refer to the ESTIA Service Manual for a detailed description for each of the controls / functions listed below

1. External room thermostat

Isolate the electrical supply to the ESTIA system and remove the cover to the electrical box in the hydro unit

Install the room thermostat into the room to be monitored / controlled. Care must be taken to ensure that the thermostat is installed in the correct position and away from the influences of other external heat sources (sunlight, radiators etc.). Follow the thermostat manufacturers installation instructions for correct positioning

Connect the room thermostat as to the TCB-PCBMO3E option PCB as shown in the diagram above

In the hydro unit set DPSW 02_4 to ON

For HEATING mode:

Set FC1A to the required setting. This will set the maximum target water temperature of the system when running in heating mode. This setting is particularly important

– if the heating emitter used is under floor heating then damage may be caused to the floor surface if FC1A is set too high

Set FC1B to the required setting. This will set the minimum target water temperature of the system when running in heating mode

Set FC9D to the required setting. This will set the initial target water temperature of the system, when the electrical supply is restored to the ESTIA system, when running in heating mode

For COOLING mode:

Set FC18 to the required setting (only required if cooling mode is available). This will set the maximum target water temperature, of the system when running in cooling mode

Set FC19 to the required setting (only required if cooling mode is available). This will set the minimum target water temperature, of the system when running in cooling mode

Set FC96 to the required setting. This will set the initial target water temperature of the system, when the electrical supply is restored to the ESTIA system, when running in cooling mode

Replace the cover on the electrical box in the hydro unit and restore the electrical supply to the ESTIA system

NOTE:

When the external thermostat is connected the end user will be unable to set any water temperatures, for the space heating or space cooling functions, on the remote controller. The system is controlled by the OPEN or CLOSED contact on the room thermostat.

49

2. Room temperature control

Isolate the electrical supply to the ESTIA system

Install the 2 nd

ESTIA remote controller (RC), for room temperature control, using 2 core screened cable. The maximum cable length specified, for the 2 nd

RC is 50m

Position the 2 nd

RC as detailed in the installation instructions supplied with the controller. It is important to position the 2 nd

RC correctly as poor positioning will affect the accuracy of the room temperature control

The remote controllers need to be configured as header and follower controllers using the

DPSW’s on the back of each remote controller (see below).

For example a customer requests that the remote controller on the hydro unit is set as the header device and the 2 nd

RC, in the room, is set as the follower to measure r oom air temperature. Set the DPSW’s as shown below:

Remote Controller DPSW

Note:

Do not set DPSW2, on both the HEADER and FOLLOWER remote controllers, to ON.

This will result in poor temperature control in the room

Restore the electrical supply to the ESTIA system

Change FC40 from 0 to 1. This will allow the ESTIA system to control using the air temperature measurement form the 2 nd

RC

For HEATING mode:

Set FC94 to the required setting. This will set the maximum room air temperature that can be selected on the remote controllers when running in heating mode.

Set FC95 to the required setting. This will set the minimum room air temperature that can be selected on the remote controllers when running in heating mode.

Set FC9D to the required setting. This will set the initial target water temperature of the system, when the electrical supply is restored to the ESTIA system, when running in heating mode

Set FCB1 to the required setting. This will select the required control option for the room temperature control when running in heating mode

For COOLING mode:

Set FC92 to the required setting. This will set the maximum room air temperature that can be selected on the remote controllers when running in cooling mode

Set FC93 to the required setting. This will set the minimum room air temperature that can be selected on the remote controllers when running in cooling mode.

Set FC96 to the required setting. This will set the initial target water temperature of the system, when the electrical supply is restored to the ESTIA system, when running in cooling mode

System Commissioning:

Measure the actual room temperature using a locally supplied temperature measuring device.

Measure the room temperature using the sensor temperature monitoring function on the remote controller (see page 51 -use code no. 03). This must process be completed on the remote controller that will be used to measure the room temperature

Compare the 2 temperature readings. If the temperature readings are the same then there is no requirement to adjust the room temperature offset FC’s. If there is a difference between the 2 temperature readings then adjust the room temperature offset using remote controller function codes (RCFC) RCFC02 for heating mode and RCFC03 for cooling mode

3. Auto curve control

The auto curve function allows the software on the hydro unit PCB to automatically calculate the target water temperature of the system depending the outdoor air temperature (OAT). This function is only available for 1 zone space heating (water temperature control).

The auto curve function is NOT available when:

Using an external room thermostat

Using a 2 nd

RC for room temperature control

Running the system in cooling mode

The auto curve control is set using function codes and by pressing the “Auto” button on the remote controller.

To set the auto curve temperatures:

STOP the ESTIA system using the remote controller

Set the following function codes to the required setting:

FC27: Sets the auto curve temperature shift / curve adjustment

FC29: Sets the OAT control temperature at point T1 on the diagram above

FC2B: Sets the OAT control temperature at point T3 on the diagram above

FC2C: Sets the target water temperature for the system when the OAT is -20°C

FC2D: Sets the target water temperature for the system when the OAT is at T1 position

FC2E: Sets the target water temperature for the system when the OAT is at T2 position (0°C)

FC2F: Sets the target water temperature for the system when the OAT is at T3 position

FC30: Sets the target water temperature for the system when the OAT is 20°C

FC31: Sets the percentage ratio of the Zone 1 target water temperature to be applied for

Zone 2 control

To activate the auto curve control:

Press on the remote controller to activate space heating

Press on the remote controller to activate the auto curve control

When the auto curve control is active the numerical temperature display for Zone 1 and Zone

2, on the remote controller, is displayed with “A” for each zone

NOTE: If the heating emitter for Zone 2 is an under floor heating circuit then care should be taken when setting FC31 to prevent any risk of damaging the floor surface due to high water temperatures

52

Zone 2 Auto Curve:.

To set Zone 2 auto curve temperatures:

STOP the ESTIA system using the remote controller

Set the following function codes to the required setting:

FC27: Sets the auto curve temperature shift / curve adjustment

FCA1: Sets the OAT control temperature at point T0 on the diagram above

FCA2: Sets the water temperature setting method for Zone 2

FCA3: Sets the target water temperature for the system when the OAT is -20°C

FCA4: Sets the target water temperature for the system when the OAT is -10°C

FCA5: Sets the target water temperature for the system when the OAT is 20°C

To activate the auto curve control:

Press on the remote controller to activate space heating

Press on the remote controller to activate the auto curve control

When the auto curve control is active the numerical temperature display for Zone 1 and Zone

2, on the remote con troller, is displayed with “A” for each zone

NOTE:

For the system to operate correctly with Zone 1 and Zone 2 auto curve selected the

temperatures set for Zone 1 auto curve operation must be greater or equal to the temperatures set for Zone 2 auto curve operation

If the heating emitter for Zone 2 is an under floor heating circuit then care should be

taken when setting FC31 to prevent any risk of damaging the floor surface due to high water temperatures

4. Auxilliary boiler control

Isolate the electrical supply to the ESTIA system and remove the cover to the electrical box in the hydro unit

Connect the start signal for the auxillary boiler to terminals 3 & 4 (EMG) of the TCB-PCIN3E option PCB as shown in the diagram above

Set DPSW 13_2 to ON. This enables the control for boiler output control

Replace the cover on the electrical box in the hydro unit and restore the electrical supply to the ESTIA system

Set the following function codes to the required setting:

FC23: Sets the OAT where the boiler output is switched ON

FC3E: Allows the boiler output to be synchronised with the heat pump or to run as an independent device

If FC3E is set to 0 then the boiler is synchronised with the heat pump. In this condition the heat pump and the boiler will run at the same time. When the water temperature, inside the hydro unit, reaches thermo OFF conditions then the heat pump will STOP and the boiler output will turn OFF

If FC3E is set to 1 then the heat pump and the boiler will run as independent devices. When the water temperature, inside the hydro unit, reaches thermo OFF conditions then the heat pump will STOP. However with FC3E = 1 the boiler output will remain ON. The temperature of the water, from the boiler, will be controlled by the boilers’ own thermostat

FC5B: Sets the operating mode for the system when the boiler output is ON:

FC5B = 0: The heat pump and the boiler will operate when OAT ≤ FC23

FC5B = 1: Boiler only operation (in this mode of operation the hydro unit pump will continue to run)

FC5B = 2: Electric heater only operation (in this mode of operation the hydro unit pump will continue to run)

FC5B = 3: Boiler only operation (in this mode of operation the hydro unit pump will

STOP and the boiler output will stay ON)

54

How to determine the setting for FC23:

The boiler output is used to switch an external boiler ON / OFF to support the ESTIA system during low ambient conditions. It is possible to estimate the switching temperature, required for the boiler output, using the system/installation capacity graph generated by the ESTIA Sales Support Software

(see graph below).

Additional heat source required

A

Required capacity supplied by heat pump capacity only

On the graph above:

The heat pump output capacity is represented by the red line

The heat load for the installation / site is represented by the blue line

The point where the 2 lines cross, point A, represents the equilibrium point of the system.

This is where the capacity output from the heat pump is equal to the heat load requirements of the installation / site. On the example above the equilibrium point is reached when the outdoor air temperature (OAT) is approximately 1°C

The area to the left of the equilibrium point and between the red and blue lines represents the area where an additional heat source is required to support the heat pump output

From the graph it can be seen that when the outdoor air temperature is -4°C there is a requirement for an additional heat source (electric back up heaters, existing boiler etc.) to supply the installation with approximately 3.5kW of heating

For the example above with FC23 set to 1°C then the boiler output will turn ON when the

OAT decreases to 1°C. The boiler will support the output of the heat pump if the OAT is 1°C or less

There is a 5K temperature differential between the boiler output ON / OFF temperatures. If the boiler output is set to turn ON when the OAT is 1 °C then the boiler output will not turn

OFF until the OAT has reached 6°C

It is possible to set FC23 lower than 1°C however this result in the electric back up heaters supplying some of the heating capacity required from the additional heat source.

55

5. 2 zone heating

– mixing valve set up

The ESTIA system has the ability to control the water temperature in 2 zones using different heating emitters (e.g. zone 1: radiators, zone 2: under floor heating circuits). This is achieved by installing a mixing valve to control the temperature of zone 2.

The mixing valve position is controlled by comparing the water set point temperature for zone 2

(entered on the ESTIA remote controller) and the actual water temperature in zone 2 (measured by the TFI sensor). Depending on the result of the comparison between the two temperatures the mixing valve will either OPEN or CLOSE (in steps) to control the temperature. The hydro unit software has been designed to drive the valve from CLOSED to OPEN in 12 steps (see the ESTIA service manual for a detailed description for the mixing valve control).

It is important that the settings for the mixing valve are set correctly using the hydro unit function codes to achieve accurate temperature control of zone 2.

Connect the mixing valve as shown in the diagram above. The valve connection to

TB04 (in the hydro unit) will depend on whether the valve is an SPST or SPDT type valve

Set DPSW 12_3 to ON. This enables 2 zone control and will allow the end user to enter a temperature set point (for zone 2) on the ESTIA remote controller

Set the following function codes:

Set FC1C to the required setting. This will set the maximum target water temperature of the system when running in heating mode. This setting is particularly important

– if the heating emitter used is under floor heating then damage may be caused to the floor surface if FC1A is set too high

Set FC1D to the required setting. This will set the minimum target water temperature of the system when running in heating mode

Set FC0C. This sets the specified drive time for the mixing valve. The drive time is the time measured to drive the valve through 90°. The drive time for the valve will be displayed in the valve specification data. It is important that this value is set correctly

– this value sets the duration of the mixing valve drive time for each of the 12 steps.

For example

– if the specified drive time for the valve is 60 seconds then the drive time for each of the 12 steps will be 5 seconds (60/12 = 5). For each step of the control power will be applied to the drive valve for a 5 second period.

Setting the value of FC0C bigger or smaller than the actual specified drive time for the valve will result in poor position control of the mixing valve and therefore poor temperature control for zone 2

Set FC59 to the required setting. This sets the temperature measuring period (measured by the TFI sensor) or sampling period between each step drive of the mixing valve. The value of this function code will depend on a number of factors (thermal efficiency of the house, type of heating emitters, size of heating circuits etc.) and so the value set will depend on the knowledge of the installer / commissioning engineer

56

Zone 2 Set: Target water temperature for zone 2

TFI: Actual water temperature of zone 2 measured by the TFI sensor a: 4 minute off time (sample period) between 230V~ pulses (sample period set using FC59) b: AC230V pulse duration determined by dividing the valve opening time (from valve specification) by 12 (the maximum number of pulses available from the hydro unit software)

Example: for a valve with a drive time specification of 60 seconds: b = 60 / 12 = 5 seconds pulse duration

On initial power up the mixing valve drives to the fully CLOSED position and then back to the mid position. This gives the mixing valve a reference position to start the temperature control for zone

2

Once the valve has reached the mid-point reference position there is a 4 minute OFF delay

(sampling period) before the valve drive to the next position. During this time the hydro unit software measures the value of TFI and compares the measured temperature to the target water temperature, for zone 2, set on the ESTIA remote controller

If the temperature, measured by the TFI sensor, is lower than the target water temperature setpoint, then the mixing valve will OPEN by one step and then the software will recalculate the required operation during the next 4 minute OFF period

If the temperature, measured by the TFI sensor, is higher than the target water temperature setpoint, then the mixing valve will CLOSE by one step and then the software will recalculate the required operation during the next 4 minute OFF period

6. Anti bacteria control (hot water mode)

The anti-bacteria control on ESTIA is used to prevent Legionella bacteria in the hot water system.

Set the following function codes:

Hydro unit function code

– FC0A: Sets the water temperature, inside the hot water cylinder, during the anti-bacteria cycle

Hydro unit function code

– FC0B: Sets the duration of the anti-bacteria function once the cylinder water temperature has reached the cycle start temperature set by FC0A

Remote controller function code

– RCFC0C: Sets the anti-bacteria cycle start time

Remote controller function code

– RCFC0D: Sets the anti-bacteria cycle operating frequency

When the function codes have been set press the button on the ESTIA remote controller. This will activate the anti-bacteria cycle set in the function codes above

When the anti-bacteria cycle is activated the anti-bacteria symbol (shown below) will be shown on the ESTIA remote controller display

57

7. Hot water boost control (hot water mode)

The hot water boost function can be used when there is a high demand for hot water. The boost function will heat the cylinder water to the set point temperature quicker than the time taken during normal hot water production.

Set the following function codes for the hot water boost function:

FC08: Sets the duration of the hot water boost function

FC09: Sets the set point temperature, of the water in the cylinder, to be achieved during the hot water boost function

When the above function codes have been set then the hot water boost function is activated by pressing on the ESTIA remote controller

When the hot water boost function is active the following symbol is shown on the ESTIA remote controller display

Nondefective operation (program operation)…….No Check code displayed

In order to control the heat pump unit, there are the following operations as the built-in program operations in the microcomputer. If a claim occurs about the operation, please confirm whether it falls under any of the contents in the following table.

If it does, please understand that the symptom is not a defect of the equipment, and it is an operation necessary for the control and maintenance of the heat pump unit.

No. Operation of the heat pump system Explanation

1

2

The compressor sometimes does not operate even within the range of compressor “ON”.

During the hot water supply or heating operation, without reaching the set temperature, the compressor operation frequency stays at a frequency of less than the maximum Hz or lowers down.

The compressor does not operate during the operation of the compressor reboot timer (3 min).

Even after the power activation, the compressor reboot timer continues to be active.

It may be caused by the high temperature release control (release protection control by the temperature of the water heat exchanger) or the current release control.

3

4

5

The “Stop” operation on the remote control will not stop the circulating pump. (The same for hot water supply, heating and cooling)

“ON” on the remote control will not operate the compressor. (It will not operate even after the reboot delay timer elapsed)

When the power is turned ON it starts operation without operating the remote controller

In order to deal with the temperature increase in the heat exchanger after stopping, the operation continues for 1 min after the compressor is stopped.

When the outdoor temperature (TO sensor detection temperature) is -20°C or lower, the heat pump will not operate in order to protect the compressor, and the heater will operate instead.

The auto restart operation may be working.

The antifreeze operation may be working. If the TWI, TWO or THO sensor detects a temperature below 4°C, the operation changes from circulating pump --->> circulating pump + heater.)

Defective operation check codes

How to determine from the check code on the remote control

If the defect is limited by the check code displayed on the remote control, please repair the defect based on the table on the next page.

The check codes are separated into two groups: software and hardware errors.

Since a hardware error cannot be cancelled without a part replacement etc., please perform a repair.

If its abnormality is determined, the abnormality is noticed by indicating the check code on the remote control check code display part while letting off a buzzer.

How to cancel a check code on the remote controller

(1) Press or button (on the operation side) to clear the check code.

(2) Press to stop a buzzer for an abnormality only.

Although the above procedure cancels the check code, the hardware error will be displayed again until the hardware repair is completed.
