Notes on System Design
• The input water temperature to the hydro unit must be 50°C or less. 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 50°C
• 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.
4
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.
5
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
9
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.
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.
Loosen the Air relief valve cap by two turns to release air (see diagram). Ensure all air is removed from the system. If air remains in the system
then the system operation may STOP.
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.

External hot water cylinder thermostat: 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)
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.
45
2. Room temperature control
Isolate the electrical supply to the ESTIA system Install the 2nd ESTIA remote controller (RC), for room temperature control, using 2 core
screened cable. The maximum cable length specified, for the 2nd RC is 50m
Position the 2nd RC as detailed in the installation instructions supplied with the controller. It is
important to position the 2nd 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 2nd RC, in the room, is set as the follower to measure room air temperature. Set the DPSW’s as shown below:
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 2nd 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 2nd 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
48
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)
49
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).
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.

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
51
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

Non-defective 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
The compressor sometimes does not operate even within the range of compressor “ON”.
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.
2
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.
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
The “Stop” operation on the remote control will not
stop the circulating pump. (The same for hot water supply, heating and cooling)
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.
4
“ON” on the remote control will not operate the
compressor. (It will not operate even after the reboot delay timer elapsed)
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.
5
When the power is turned ON it starts operation without operating the remote controller
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.
