1.2.4 Identifying the equipment

A legible and indelible data plate listing the specifications of the unit is affixed in a visible location on the unit.

This information (particularly the description and the serial

1.3 Basic safety rules

To prevent the risk of accidents during installation, system start-up and adjustment, it is essential to remember that a heat pump contains a pressurised refrigeration circuit and refrigerant, as well as electrical voltage and fluid at a temperature up to 150°C (risk of burns from touching the pipes) number ) must be quoted in all correspondence.

The HP MAX value: PSM indicated on the name plate is the maximum operating pressure (= 42 bar)

This value corresponds to the activation pressure for the safety device: the HP pressure switch. A burst test on a representative model is carried out periodically in accordance with standard

EN 378-2. The burst pressure must be at least 3 times the operating pressure, i.e. 3 x 42 bar = 126 bar.

1.2.5 Handling

Units on pallets must be transported using a pallet truck.

Warning: the machine must be moved using a suitable means of transport. The heat pump must not be dragged along the ground directly on its rubber feet, as this may damage the adjustment system.

Wear suitable gloves when handling the unit.

1.2.6 Installation

CIAT units must only be installed by experienced, qualified personnel with the necessary electrical and hydraulic accreditation. The installing company must provide the equipment manager with a declaration of conformity in accordance with current standards and the indications supplied by CIAT in this manual. The recommendations and instructions given in the maintenance brochures and the special instructions on the labels must be followed.

Always comply with applicable standards and regulations.

Note that certain basic safety rules apply to the use of this type of unit:

• Before carrying out any work on the equipment, ensure that the supply voltage is switched off (and the capacitors discharged). Any electrical discharge carries a risk of injury.

• The unit must not be used by unsupervised people with disabilities or children.

• It is forbidden to touch the unit in bare feet or if any part of the body is wet or damp.

• It is forbidden to modify the safety or adjustment devices without authorisation and instructions from the device manufacturer.

• For work on the machine during or shortly after operation, wear gloves suitable for high temperatures and electrically insulated tools.

1.4 Waste disposal by users in private waste facilities within the European Union

This symbol indicates that the product and its packaging must not be disposed of in ordinary household waste or in the natural environment. It is your responsibility to ensure your waste is taken to a designated recycling point for electrical and electronic devices.

2. INSTALLATION

2.1 Location of the control terminal and the heat pump

2.1.1 Control terminal

At delivery, the HomeConnect control terminal is located behind the GeoCIATTM Modular unit.

Outdoor sensor

Control terminal

EN

Location

Before fixing the control terminal in place, check the range of the radio signal. This should be at the maximum level.

If this is not the case, you can also move the heat pump a few centimetres to ensure optimal transmission of its radio signal.

Selecting a location

The terminal operates permanently as a room thermostat. It is therefore essential to place the control terminal inside the home, within the environment to be monitored and away from heat sources (chimney, radiator, sunlight), draughts (windows, doors) and areas of activity.

Mounting

The terminal is supplied with a wall mounting plate (base) and a base.

The wall mounting plate should be affixed using screws and wall plugs (FS Ø4 mm flat head slotted screws, Ø5 mm wall plugs), which are not supplied, using the holes marked on the mounting plate.

The battery compartment has ribs on either side to hold the terminal on its mounting plate.

Once the mounting plate is affixed to the wall, slide the terminal into place.

The terminal is positioned in the same way on the base.

EN - 7

2.1.2 Outdoor sensor

At delivery, the outdoor sensor is located inside its own box behind the heat pump. It sends a temperature value to the control board every 30 minutes, or if there is a variation of around 0.5°C.

a) Installation and location

Position the outdoor sensor on the front of the frame, orienting it as far north as possible.

Make sure the outdoor sensor is not exposed to direct sunlight, and place it in a vertical position.

Incorrect positions b) Mounting

Proceed as follows to remove the sensor's cover: u

Turn the cover anticlockwise to align the 2 arrows on the side v

Detach the cover from the wall bracket

Correct position

- Drill 2 holes (6 mm diameter) in the wall, one above the other approximately 17 mm apart

- Affix the wall bracket in the recommended position using the mounting holes provided

- Position the elongated hole horizontally at the bottom: the word UP must be legible

- Affix the wall bracket using screws and wall plugs (FS Ø4 mm flat head slotted screws, Ø5 mm wall plugs), which are not supplied, using the mounting holes

To close the sensor:

- Place the cover on the body.

- Turn the cover clockwise to lock it.

Mounting holes

2.1.3 GeoCIAT

TM

Modular heat pump

The GeoCIATTM Modular must only be located inside a machine room, garage or laundry room. Ensure that the structure of the machine room can support the weight of the unit. The module must be perfectly level (adjustable feet under the

GeoCIAT TM Modular) and installed with the minimum free space as described in paragraph 1.6.

Sound level: our units are designed to operate quietly. However, as soon as you begin designing your system, you should take into consideration its position in your home. The unit must not be located near bedrooms.

Placing the unit in a corner will substantially increase its sound level. Ventilation ducts and clearance zones can also transmit noise. If in doubt, have an analysis performed by an acoustical engineer.

Positioning: when positioning the unit, lift it without tilting it too much

Accessibility: leave sufficient room around the unit to allow easy access for installation and maintenance (see diagram in paragraph 1.6).

2.2 Hydraulic connections

Pipes

Adhere to the installation standards and trace the pipe routing carefully:



observe the drain direction (inlet/outlet) indicated on the unit



the following accessories are essential to any hydraulic system and must also be installed

- 3 bar valve-gauge assembly (mandatory)*

- automatic air bleed valves at high points

- discharge nozzles at low points

- balancing valves

- additional expansion vessels if necessary

- thermometer pockets, etc.

* the safety valve, which is mandatory on the hydraulic circuit, must be tested manually at least once a year.



the pipes and tubes should not transmit any forces or vibrations to the exchangers. Hoses must be used to connect water pipes.



use at least 2 shut-off valves on each circuit in order to isolate the unit

- screw in the system's flexible connectors/pipes by hand

- tighten them using two spanners

Failure to tighten with two spanners could cause the couplings to rupture and may result in the equipment warranty being voided.

EN

Fasten the water pipes to the walls with brackets lined with highly flexible rubber to prevent the transmission of vibrations.

Insulate the pipes and hoses carefully to prevent heat loss and condensation.

*Intermediate exchanger:

This exchanger is mandatory for water-to-water operation, and protects your GeoCIAT TM Modular from:

- fine suspended solids (risk of clogging) or aggressive water.

- iron, manganese or chlorine (risk of corrosion or deposits)

We therefore recommended that you have the physical and chemical properties of your water analysed (B3C3 type analysis) to determine what types of materials should be used.

This exchanger also limits the number of times the frost protection is turned on when your system is started up in cold weather or after a prolonged period without use.

CIAT declines all liability for clogging and malfunctions of the exchanger in the GeoCIATTM Modular if this exchanger is not installed.

A constant flow of water must be maintained in the exchangers.

System frost protection (at the installer's expense)

CIRCUITS

Indoor circuit: Parameter P5 is used to add glycol to the indoor circuit. A glycol/water solution is not necessary in certain areas, if you are absolutely sure that your indoor circuit will always remain at above-freezing temperature. If in doubt, use 40%

MPG (monopropylene glycol).

Outdoor circuit:

- The loop between the intermediate exchanger and the heat pump must contain a 20% MPG solution.

- Parameter P06 must be set to NO if the indoor circuit does not contain a glycol solution or 40% MPG if the outdoor circuit contains a 40% glycol solution.



FROST PROTECTION

We highly recommend that you drain sections not protected by glycol/water solution (well loop and, if need be, the indoor circuit) if you turn off the heating system intentionally or if there is a risk of it being accidentally turned off.



Sections that must be protected by glycol/water solution should contain the following proportions of MPG (other antifreeze with the same freezing point may also be used):

20% MPG: freezing point = -8°C

40% MPG: freezing point = -25°C

The antifreeze may be mixed with a corrosion inhibitor and even a biocide (follow the instructions of the anti-freeze manufacturer). Ready-mixed solutions and dilutable products may also be used.

PROCEDURE

Preparing the system to be protected:



Always flush the system completely and blow it out to remove any remaining water.



Washing the system with a suitable cleaner is recommended (use a cleaner compatible with the system's materials).



Follow up the final rinse with a complete drain of the system.

Add the water/antifreeze/corrosion inhibitor mixture and pressurise using the hydraulic pump.



If you use a concentrated dilutable solution, follow the instructions below:

- Always dilute the antifreeze with water before adding it to the system. Never add them separately.

- Always mix the correct amounts of water, antifreeze and corrosion inhibitor in a container before adding them to the system.

- Drain the system thoroughly.

- Allow the mixture to run through the entire system for at least

2 hours before starting the heat pump.

-Use a hydrometer or a refractometer to check the final proportion obtained.

Using litmus paper or a pH meter, check the pH obtained.

Affix, in a visible location, a label stating:

- that the system contains antifreeze.

- the name of the product and its supplier.

-the proportion and the pH at commissioning.

EN

Do not use products made with monoethylene glycol (which is toxic)

2.3 Electrical connections

- Remove the unit's front panels to access the electrics box

(see instructions in paragraph 1.2.2 Removing the shipment protection).

Connect to terminal blocks J1, J2, J3, J4 and J5 according to the HomeConnect board' supply mode (single-phase or threephase) (see paragraph 2.3.3). For a three-phase power supply, use terminals N(J4), L1(J3) and the green/yellow terminal (J5).

Make sure the terminals are securely tightened.

- Select the supply cable using the table below.

The electrical characteristics of the mains supply must be identical to those on the name plate. The power supply must meet the following requirements:

230 V and 400 V

+ 6 %

50 Hz for 20H/33H/45H single-phase + Neutral + Earth models.

+ 6 %

- 10%

50 Hz for the 45HT three-phase + Neutral + Earth model.

It is your responsibility to protect the unit from mains voltage spikes and voltage spikes caused by lightning. Depending on the geographic location and the type of mains network (buried or overhead), you may have to install a lightning rod.

Check your local electrical codes and regulations.

IMPORTANT :

- Connect the unit to earth before making any other electrical connections.

- The three-phase model must have a neutral.

- The system must be fitted with a main cut-off switch

3. COMMISSIONING

It is advisable not to connect pressure gauges to the refrigerating circuit when starting up the unit (except in the case of incidents). Taking temperature readings is sufficient in most cases. Refer to the information on the HomeConnect terminal (see paragraph 5.3 "configuration").

3.1 Checks

- Check for any refrigerant leaks.

- Open the valves on the water circuits and make sure water is flowing through the heat pump.

- Bleed all the air out of the water circuits.

- Check for loose electrical connections.

- Make sure that the supply voltage matches the unit voltage and that its value remains within the permissible limits for the nominal voltages.

3.2 Starting up the unit

The procedure below is used to prepare the electronic board for pairing with the control terminal, with the control terminal powered off.

3.2.1 Powering up the terminal

- Place the 3 batteries in the battery compartment located on the rear of the terminal.

- Foolproofing devices prevent the batteries from being incorrectly inserted.

- When the terminal is first powered up, all the pictograms are displayed for 3 seconds before the initialisation phase begins.

Note: remember to remove the plastic tab from the battery compartment in order to power on the terminal.

3.2.2 Initialising the terminal

After setting the temperature unit, the Heat pump pairing menu appears on the screen to establish communication between the control terminal and the heat pump.

3.2.3 Heat pump pairing

The unpaired GeoCIAT TM Modular which is supplied with mains power activates a series of actions to prepare for system start-up:

- activation of the accelerator pump to bleed air from the heating circuit

- activation of the electric heating elements with a setpoint of 25°C.

While the machine is unpaired, the relays on the electronic board are activated to supply the indoor accelerator pump and the electric heating elements. The only control active in Unpaired mode is monitoring of the water return temperature level to obtain a water setpoint of 25°C (hysteresis: 21°C).

The accelerator pump supply activates the air bleed sequence (12 hours with the accelerator pump stopping for 5 minutes every

15 minutes):

- accelerator pump start-up with on/off cycles.

Once the machine has been paired, the latter exits system start-up preparation mode by setting the actuators indicated above to the rest position.

3.2.4 Machine configuration

- Set the machine parameters according to the type of system (see Machine parameters table in paragraph 5.3).

Lock parameter P99 on YES. Parameter P99 is accessible in the Machine parameters sub-menu of the Unit configuration menu.

The on/off icon is displayed in the main menu.

3.2.5 Starting the heat pump

Position the on/off icon in the main menu selection box then confirm by pressing the button. The unit starts up in comfort heating mode by default. The accelerator pump starts up, then once the short cycle protection is completed the compressor starts up.

Specific to single-phase models:

In order to meet the requirements of French standard NF-C 15 100 on start-up current limits, your unit features a smart system that monitors this current. In order to enable the electronics to self-configure and thus adapt to your system, it may not take place instantaneously when started for the first time (or after a power cut). The unit may attempt to start, acquire some values and then restart under the best possible conditions.

Specific to the three-phase model :

The GeoCIAT TM Modular 45HT model does not have a phase controller as standard. Electrical connection of the control board may cause the compressor to rotate in reverse. This is not harmful to the compressor if it is stopped quickly. 2 outcomes are possible:

- The compressor noise will alert you to reverse rotation => Stop the heat pump using the ON/OFF button on the HMI then reverse the 2 phases on the electronic board (power off first)

- The monitoring software detects a "COMPRESSOR ROTATION" fault => reverse the 2 phases using the above procedure.

EN - 29

3.2.6 Adjusting the accelerator pump

- On units of all sizes, the accelerator pump is equipped with a release screw. It may be necessary to use it when starting the system or when powering it off for extended periods of time.

The accelerator pumps are EC type. The speed is controlled according to the various scenarios encountered by the control. The variable speed control is PWM type. On the indoor accelerator pump, speed variation usually takes place during unit start-up. On the outdoor accelerator pump, speed variation takes place according to the sensor's return temperature. There are 2 control parameters accessible from the level which are used to decrease or increase the default level of the speed thresholds (P122 to P125). This scenario may be applicable if there are loud noises in the pipes.

Release screw

3.3 Air bleed sequence

To keep your system running smoothly and, more specifically, if your GeoCIATTM Modular is installed at a high point, you must bleed the air contained inside it at the time of commissioning. The machine is not equipped as standard with an automatic air bleed valve. However, it is strongly recommended to install one on the circuit's high point.

A new function has been integrated on this machine: preparation for system start-up.

The GeoCIAT TM Modular is equipped with an automatic function which, when the heat pump is not paired, starts the air circuit bleed sequence by electrically connecting the heat pump to the electrical network.

If the heat pump has been paired and there is still air in the circuit, a manual bleed may be requested using the procedure below:

Select the Air bleed sequence in the System start-up sub-menu of the Unit configuration menu, then select the value YES in the setting field.

The function is activated if the unit is off.

Remember to take the cap off the automatic bleed valve.

4.1 Unit maintenance

Working on the compressor

The compressor is fastened to the platform by four 8 mm diameter screws (or 3 screws depending on the model).

Warning: tighten these screws to a torque of 13Nm +/- 1Nm.

If you do not have a torque wrench, tighten them until they are snug then tighten a further 3/4 turn.

Working on the accelerator pump

The accelerator pumps are equipped with a release screw. It may be necessary to use it when powering the system off for extended periods of time.

However, the accelerator pumps are EC type. The torque is controlled electronically and therefore should not require much manual intervention.

Working on the sensors

The LP and HP pressure sensors are accessible via the base of the refrigerating block. There are 2 options for accessing the sensors:

There is no option on the GeoCIATTM Modular. The refrigerating block's top cover is easily accessible

=> working on the sensors by removing the 2 roof sections.

There is one option with the GeoCIATTM Modular ; the roof is diffi cult to reach

=> working on the sensors by removing the electrical panel

The pressure connectors and sensors are accessed by moving the electrical panel to the right after unscrewing the panel retaining screws and removing cables which are too short.

The pressure connectors and sensors are accessed via the top of the refrigerating block

The HP pressure switch is accessed via the front of the machine.

To access the sensor:

The HP pressure switch is held on the capillary tube by a clip

Working on the expansion vessels

The expansion vessels must be re-infl ated every year to ensure optimal operation.

To do this, close the water inlets and outlets on the heat pump circuits and undo the fl exible connections on the expansion vessels. Remove the retaining screws from the mounting bracket and lower the transverse bar.

EN - 32

Working on the electrical panel

The tightening torques for the electrical power wires are as follows (depending on the component to be supplied):

- single-phase starter: 1.2 Nm

- three-phase starter: 1Nm

- power switch: 1.2 Nm

Specific requirements for refrigerants

Maintenance operations on the heat pump must only be carried out by a maintenance company whose personnel are qualified to handle refrigerant fluids in accordance with order CE No. 842/2006.

R410A refrigerant fluid is a gas which has the following impact on the environment:

1/ No impact on the OZONE layer : ODP (Ozone Depletion

Potential) = 0.

2/ Impact on the greenhouse effect : GWP (Global Warming

Potential) = 1975.

- Units containing over 3 kg of refrigerant (2 kg in France, decree and order of 7 May 2007) must be periodically checked for leaks by qualified maintenance personnel.

- For all systems which contain over 3 kg of refrigerant (2 kg in

France), users are required to keep a log of the quantities and types of fluids used, added and recovered as well as the dates and results of the sealing tests, the name of the technician and the company concerned. We strongly recommend that you keep this log up to date.

- A leak test must be carried out one month after any leak repairs.

- The maintenance company is responsible for collecting used refrigerant and having it recycled, regenerated or destroyed.

4.2 Checks

Mandatory annual checks:

- Leaks on the refrigeration circuit.

- Check for loose electrical connections

- Check the glycol mix and pH. Always top up with the same type of mix initially used.

- Check the water filters for dirt. The filters may need to be checked more frequently.

4.3 User recommendations

To ensure that the unit operates correctly, we recommend that you sign a maintenance contract with your installer or an approved maintenance company. Consult our list of CIAT

5.5.2 Boiler heating element (P11=BOILER)

Corrosion of heating sources

Heating sources, such as those made of steel, are susceptible to corrosion. Please contact your boiler manufacturer to determine whether the heating source is compatible with HomeConnect control. (e.g. maximum and minimum operating times, etc.)

A few recommendations

- do not operate the burner and the heat pump simultaneously at water temperatures below 40°C with P13 at HP +

HEATING ELEMENT. If in any doubt, set P190 and P191 to the same value.

- Do not short-circuit the boiler corrosion protection systems (e.g. heating accelerator pump kept off until the burner raises the heating source temperature to over 40°C).

5.5.2.1 Boiler controlled by its own control P11 = BOILER and P12 = ALTERNATE

Typical application: boiler equipped with advanced electronic control.

By setting P11 = BOILER and P12 = ALTERNATE the HomeConnect controller only supplies an operating authorisation contact to the boiler. The direction of action of this contact (terminals L - H. EL J45 and J46) can be adjusted via parameter P17.

The boiler is authorised to operate when the outdoor temperature falls below the value of P191 or if the heat pump malfunctions.

The boiler burner is then controlled by the boiler's control system.

Misc.: The accelerator pump can be stopped using parameter P121:

P121 = NO: accelerator pump turned off if boiler operating.

Moreover, a LOW INT WATER FLOW fault must not prevent the boiler from operating. Therefore, the boiler is authorised to start up even if this fault appears.

P121 = YES (default value): accelerator pump continuous operation.

5.5.2.2 Boiler controlled by its own HomeConnect controller P11 = BOILER and P12 = SIMULTANEOUS

Typical application : boiler with basic control.

When P11 = BOILER and P12 = SIMULTANEOUS, the burner and the heat pump are controlled by the HomeConnect controller using the water law entered on the terminal (parameters P152 to P156).

In simultaneous operation, the HomeConnect controller also provides a contact to control the boiler's 3-way distribution valve.

This contact (terminal block J33 - terminals 1 and 2) is permanently closed once the controller authorises boiler operation. The contact opens 5 minutes after the boiler operation prohibiting order in order to recover as much heat as possible from the hot water contained in the boiler's heating source.

If only the boiler is authorised to operate, the control terminal manages the ambient temperature and the controller controls the boiler operation based on the ambient air setpoint (P150 or P151). Control is then via the P183 differential (factory setting = 1°C).

Example:

Heating mode in comfort mode: P150=21°C and P183=1°C.

The boiler is authorised to operate if the ambient temperature is below 20°C and is turned off once the ambient air setpoint of

21°C is reached.
