Important Safety considerations - Please read before working on this appliance
To avoid issues that could damage to the appliance or cause injury this appliance must be installed by a suitably
qualified competent contractor. All electrical wiring associated with the appliance must be completed by a
licensed electrical contractor in accordance with NZ / AU Standards.
To reduce the risk of electrical shock. first make the water connections, then electrical connections. If the unit is
to be removed first disconnect the electrical connections, then the water connections
Disconnect at the main power supply before exposing any internal parts of the appliance. In case of malfunction
turn the unit off, isolate the mains power supply and contact a qualified service engineer.
Defects found during installation must be rectified before commissioning. If repairs are carried out then the
operation of relevant safety devices & parameters must be rechecked.
If a refrigerant leak occurs, remove the complete charge using a recovery unit & store the refrigerant in a suitable
for purpose mobile container. When a leak Is rectified recharge the unit with the correct filling weight and Gas
type. This can be found on the appliance data plate.
Ensure the correct refrigerant gas is used to recharge the unit as incorrect gas will cause severe damage to the compressor. Care should be
taken as refrigerant can breakdown due to high temperature, these refrigerants by-products are dangerous.
Do not use oxygen to purge refrigerant lines or to pressurize under any circumstance Oxygen gas reacts violently
with oil, grease and other common substances. Use only dry nitrogen for testing and never exceed the specified
maximum operating pressures.
Do not un-weld or flame cut refrigerant lines or refrigerant circuit components until the entire refrigerant (liquid
and vapour) is removed from unit. Traces of vapour should be displaced with dry nitrogen. Do not siphon
refrigerant. Refrigerant in contact with an open flame will produces toxic gases.
Ensure that the necessary safety protection equipment is available. Have an appropriate fire extinguisher to
hand when working on this appliance.
Take care with refrigerant Avoid spilling liquid refrigerant onto skin or splashing it into the eyes. Use safety
goggles. Wash any spills from the skin with soap and water. If liquid refrigerant enters the eyes, immediately and
abundantly flush the eyes with water and seek urgent medical advice

Installation Location
▪This appliance must be installed outside on a concrete pad foundation not connected to the house
foundation.
▪If operating in temperatures below 0°C for prolonged periods or locations where the snow may fall the base
must be raised. we recommend 200 mm above ground to avoid ice build-up on the unit’s chassis.
▪The unit should ideally be placed so that it is well away from bedrooms or noise sensitive areas including
neighbour’s section boundaries. (The unit may produce noise that exceeds a 45 decibel rating).
▪A North facing location aspect will give higher efficiency than a South facing aspect.
▪Make sure discharge water cannot run out onto paths as it may cause ice or slime to build up which is a
Hazard. (The unit is fitted with a collection tray and outlet spigot for waste discharge connection)
▪Avoid locations exposed to machine oil vapour, salt air, thermal springs, sulphur gases or other harsh
substances. In areas with exposure to the above additional treatments must be applied by the installer to
protect the appliance. This will form part of the on-going maintenance regime, the effects of a harsh Costal or
Geothermal atmosphere are not covered by warranty and may shorten the working life.
▪Locations exposed to strong winds should be avoided otherwise baffles may be necessary to deflect strong
winds. Baffles must not restrict air flow & should be at least 2m from the appliance. A baffle is better if it is
not a flat face as this may magnify sound e.g.: a bush is better than a wall
▪The unit must be installed level in both axes (less than 2mm tolerance per meter)
Direct offshore wind
Indirect offshore wind
▪Keep a suitable distance between the unit and the building to ensure normal operation of the appliance and
provide enough room for maintenance.

System operation Overview 1 heating only
Heating Mode Working Principle: Same As overview 2 below but there is no three way valve (VXV)
System operation Overview 2 Heating/Cooling/DHW production
Heating mode working principle
When In heating mode, the 3 way valve (VXV) will be in the default open to heating position.
In heating mode, Compressor is On : When the RT sensor drops below (heating set point ST02) by (differential ST04) -Then - The
compressor will turn Off: when the RT sensor is ST02 + 2℃ and running frequency of the compressor has reduced to Minimum for 120s.
T (heating) calculation:
Default ST02 =35, ST06 =0.6
1.) When SF04 =No, there is no heating curve. T (heating) = ST02. 2.) When SF04 = Yes, heating curve is activated,
T (heating) ＝ST02 +（20 - OT）X ST06. If calculated T (heating) is higher than ST14, ST14 would be T (heating).
Refer to chapter “Heating compensation curve setting”.
Auxiliary Electric backup element, or boiler control (Element included as default in NZ appliances)
The integral auxiliary backup element can only be ON when all of conditions below are met.
1.) Heating mode is operational and the compressor has been running on the maximum workable frequency.；
2.) The compressor has run for over 300s 3.) OT Sensor is below ST07 4.) RT sensor is ST02 is -ST04-2；
The auxiliary backup element is OFF when either of these conditions are met. 1.) A/C flow alarm. -Or- 2.) RT is ST02 - 2
Cooling mode, working principle:
In cooling mode, the 3 way valve (VXV) will open in the default heating position. (Where only part of the overall system is used for cooling
there may be a requirement for further motorised control valve/s to be includes in the system design, these are not covered in this manual)
The compressor is ON when: the RT sensor is over ST01 + ST03（ST01is the control water temperature in cooling mode）
The compressor is Off: when the RT Sensor is below ST01 by 1.5° & running frequency of the compressor has reduced to minimum for 120s.
T (cooling) calculation:
Default ST01 = 13, ST08 = 0.6
1.) When SF04 = No, there is no cooling curve. T (cooling) = ST01.
2.) When SF04 = Yes, cooling curve is activated, T (cooling) ＝ST01 +（35-OT）X ST08
If calculated T (cooling) is lower than ST11 then ST11 would be T (cooling).
Domestic Hot water production working principle:
In hot water mode, the 3 way valve (VXV) will open to feed the hot water cylinder coil, closing the heating port.
1.) When ST09 is set below ST20
Compressor is turned ON when HT sensor reads ST09-ST10 then - The compressor will turn Off when HT sensor reaches ST09
2.) When ST09 is set higher than ST20
Compressor is turned ON when the HT sensor is below ST20 by ST10 then- The compressor will turn off when HT sensor reaches ST20
So: when DHW set point ST09 is lower than ST20, only the compressor is switched on to produce DHW.
Or: When DHW set point ST09 is higher than ST20, DHW will be heated to ST20 by the compressor, then the managed electric element in
the DHW cylinder will be switched on to raise the DHW up to the ST09 set point.
System operation overview 3: Multiple Units in Series Cascade Connection
Heating working principle
To set two units in parallel operation, set the primary unit to the required parameters, and the other to have a 2~5°C difference of the ST01
and ST02 parameters to allow for energy stage control.

INSTALLATION
Pipe - system connections
It is important that you follow the installation information provided here.
Pipework and valve train requirements must be in line with the schematics on page 4 or as prescribed in the
system design provided by the distributor.
1. Installation must adhere to NZ Building & Plumbing Codes, including any local council requirements.
2. Ensure that flow and return pipework is correctly sized for the system and appliance and that they are not
reversed. Reversing the water flow will reduce the output of the unit; refer to the labels on the unit for the
correct water flow direction.
3. Pipe connections must avoid any radial or axial forces to the heat exchanger. Allow some pipe flexibly between
the unit and the structure to reduce any stresses and vibrations issues. Flexible union connections with rubber
gaskets should be used where possible to reduce potential for vibration transmission.
4. Pipework installation must be run to minimise the use of elbows as they can restrict flow. Use bends in
pipework rather than elbows wherever practical to do so.
5. It is essential to insulate all of the system Flow and Return pipe work including HP connections and pipework
within the building, including fittings. This is to protect against both thermal heat loss, impact from frost and
importantly to prevent condensation on chilled pipes where cooling is adopted.
6. Protection devices must be included to protect the appliance from operating outside of its parameters these
must include, air relief valve/s, a 3 bar safety valve, a particulate (Y) strainer on the return and a correctly sized
expansion vessel. Failure to provide any of the above items will void the warranty on this appliance.
7. Isolation service valves must be fitted at the heat pump to facilitate future service requirements. A drain
connection at a low point in the pipework is required to allow the system to be drained if required.
8. Water to fill the system must be clean, and must not contain heavy metals or minerals that could cause harm
to the unit.
Note it is important to ensure that any new heating system installation attached to this appliance is
thoroughly flushed, before connection to this appliance. A system cleaner product such as Kamco Hyper flush
must be used to flush any pre, existing system that this appliance may be attached to.
9. Water within the system must be treated with an approved inhibitor to prevent corrosion, fouling and
deterioration of the system. The inhibitor level should be tested annually, and the dosage maintained. Kamco
System-safe DM & Fernox are approved. Please confirm suitability if you wish to use an alternative product.
Failure attributable to a lack of inhibitor will not be covered by the appliance warranty.
10. A filling loop with braided filling hose, a pressure limiting valve set to 1.3 Bar and gauge should be provided,
such that it will allow the user to easily top up the system pressure. This assembly should not be permanently
connected and active and must include a check valve.
11. For appropriate sizing and set out of A DHW cylinder refer to page 11
Warranty extends to the use of this appliance as prescribed for the purpose for which it is supplied only.
Warranty is void where the appliance is incorrectly installed and or operated.

Control connections continued
Heating function switching control connections
There are two possible methods to turn ON/OFF the Heating (A/C) function ( settable via SF14)
If SF14 is set to, “keyboard” (the factory default setting). Then external system controls do not control the unit,
the Carel user interface maintains control over the appliance.
If SF14 is set to “remote”. The Carel user interface can no longer be used to turn the heating On or Off. its heating
time zone On/Off function is deactivated. Terminal Connections B1-B2 are now used to turn On/Off the heating,
Via a volt free signal from external system controls
EG; An external signal like a timer, thermostat, or under-floor wiring centre with a volt free switch output are
connected to B1-B2 to activate the unit’s heating function as required. As below
Domestic Hot water function switching control connections
There are two ways to turn ON / OFF the domestic hot water function (Settable via SF13).
If SF13 is set to by “keyboard” then the DHW input is fully controlled by the Carel user interface
If SF13 is set to by “remote” Then DHW demand is controlled by an external control. In this setting the Carel user
interface cannot be used to turn On or Off the DHW and its time zone function is disabled.
If SF 13 is By remote The A1-A2 switch connection in the HP is activated to turn On or Off the hot water function via an
external system control such as a timer wired to it. As below
DHW element control principal：
1.) If ST09 is set below ST20, DHW is only heated by the compressor. If ST09 is set above ST20, compressor stops
heating DHW after HT reaches ST20 , and the element is switched on until HT reaches ST09.
3.) If there is a compressor fault and there is DHW demand, the element is switched on until HT reaches ST09
Legionella protection
4.) The Element is switched on to kill legionella bacteria until HT exceeds ST27, if HT is not over ST27 in the time
interval ST26.
If ST26 = 0, Legionella function is not active. By default ST26 =360 Hr’s this can be set to between 0 and 1000Hrs.

Auxiliary Electric Heater, or Boiler backup.
NZ/Australia all models are equipped with an integral heater (Element) as standard.
The auxiliary heating element is fitted inside the unit, it is connected to the control board via a relay
If the auxiliary element is not fitted, there is a connector on terminal block numbered (3-4) . An auxiliary electric heater or a
boiler could be connected to 3-4 via a relay JQ1 for provision of heating backup. See below.
DHW Cylinder element control
Connector (5-6) are to be used to activate and de-activate the DHW cylinder element for heating domestic hot water this
output must be via a relay JQ2. (not provided)
Important: do not connect elements directly to the terminal block - this will burn-out the controller.
For auxiliary heating electric heater running regulation refer to the section "system overviews”
(Single phase)
(Three phase)
If the domestic hot water is to be reticulated, then our optional DHW circulation pump
can be installed in the domestic hot water reticulation loop connected to cylinder. The
reticulation pump power supply is connected to terminals (1-2) on the terminal block.
DHW circulation pump, operating principal:
1.) When DHW mode is on, the reticulation pump will be switched on and run for a
period of ST34 in every ST33 interval. Eg; 3 minutes every 15 minutes

Typical DHW cylinder set up (standard DHW cylinder or Combi-tank)
It is important to use a cylinder that is fit for purpose. A heat pump delivers coil input at a much lower
temperature and transfers heat with a much lower differential between the body of water and the heating
coil compared to a boiler, wetback or solar. The coil in a cylinder used with a heat pump must have
considerably larger surface area to enable effective heat transfer. If you have a dual coil cylinder you
may connect the two coils together in series for improved input performance
There is nothing to gain from over sizing a DHW cylinder in a heat pump system, a 250L cylinder would be
more than adequate for most homes.
Shown above are a Typical DHW cylinder, and the Heat IQ Eco+ combi tank
Using the conventional cylinder
•The cylinder is piped via a three-way valve from the primary flow and return. these connections for the
cylinder coil F/R are made in the line before the hydraulic separator or buffer tank.
Using the Eco+ Combi tank
• Designed to optimise the energy efficiency of the system in this format a buffer tank within the cylinder
shell has a coil used as a pre heater for DHW. By doing so Combi-Tank® utilises the higher COP energy
from the buffer reducing the requirement for lower COP input through the three way valve to cylinder
coil.
• The efficient option for any system, Combi-Tank® also allows the system the option to input solar PV
energy into both the DHW and the Heating system via elements, for even greater energy efficiency.
• Having both the Buffer tank and Cylinder within a single shell simplifies installation and keeps the system
neat while using less space.
• Combi-Tank® can also be installed with the optional management module for further energy saving
features and user options. (See Combi-Tank manual/brochure)
*When including a Combi-tank® please refer to the specific element control
options in the Combi Tank installation instructions.

Commissioning
Compressor crankcase heater
This appliance is equipped with a compressor crankcase heater to heat the compressor oil and evaporates any
dissolved refrigerant before start-up.
▪When the outdoor temperature is above 5° and below 10°, The unit must be in a standby state for 1 to 2 hours before
the unit is run for the first time, if the temperature is below 5° for 3 hours and below 2° for at least 6 hours. This ensures
compressor crankcase heater has the compressor oil is at the correct temperature before the FIRST start, ensuring that
no damage is done to the new compressor.
Preparations- Filling and Flushing
1. Before commissioning, ensure the whole system has been fully flushed and re filled with fresh water.
2. Check the pipe work in the associated system for leaks.
3. Vent air out the system using the air venting valves.
4. The system must be dosed with an approved inhibitor and set to the required ( 1.1 to 1.5 bar) pressure
We also recommend the inclusion of a biocide dose to prevent contamination of low temp systems
Start-up and Inspection
1. Start the unit by turning on the heating control system and therefore switching on the unit.
2. The water pump will start, then over a period of delay the fan motor, and finally the compressor.
Air in the System after Start-up
▪Air will initially be released from the water as its heated so further venting may be required.
▪If a bubbling sound can be heard from the heat pump, the circulation pump, under-floor and or radiators then
the entire system will certainly require further venting.
Inclusion of a pressure limiting valve set at 1.1 bar as part of the filling loop will allow the system filling point to remain active
throughout commissioning and may be left active for a few days while the system is initially used. It is also a recommended
this valve remains as part of the filling point as this will avoid the potential for over pressure when topping up the system.
The system filling loop should not be left as a permanently open fill point as this will mask any leaks and is non compliant
A permanently connected filling loop may void a claim under the appliance warranty.
Once the system is stable the heating control systems can be fully set as required, and operationally tested.
Frost Protection IMPORTANT
Local climatic conditions are to be considered by the installing contractor.
Requirements for the introduction of glycol are not covered in associated system design provided by the distributor.
It is the installer’s responsibility to ensure adequate consideration is given to requirements for frost protection.
In areas where Temperatures may consistently fall below 0°C A Glycol solution may be required.
1. Add the correct percentage of suitable glycol antifreeze to the water circuit. For example You can purchase
Kamco Freezbreaker from Heat IQ (NZ)
Freezbreaker at a dose of 12.5 % volume in the system gives protection to - 6 / 25% to -12 / 40% to – 20 )
2. Power to the unit must remain on all the times in order that the appliance can start the circulation pump and auxiliary
heater for the integral anti-freeze protection.
Warranty does not cover damage where inadequate frost protection is a contributing factor
(Refer also to installation location instructions)

1. Low pressure, low temperature liquid refrigerant coming out of the expansion valve exacts heat energy from the air
passing through a densely finned coil heat exchanger ① and evaporates into a gas state.
2. The gas state refrigerant is sucked into the compressor ②compressed to high pressure and high temperature gas.
3. This high pressure, high temperature gas is discharged, and the compressor releases its heat energy transferring it to
water via the plate exchanger ③ as this happens the gas is condensed to liquid state.
4. The now liquid state refrigerant is expanded in thermostatic expansion valve ④ and again becomes low pressure and

Time-zone on/off
The time-zone function activates the pre-set timer programs. A time-zone function is only valid when unit on/off
method is “by keyboard”.
TR10: HW time-zone is for domestic hot water. When TR10 is enabled, two different time periods are available to set
in every day from Sunday to Saturday.
After setting for Mondays times scroll to “Monday” and press up or down button to change to Tuesday to set its timer,
and so on. If the ON and OFF data are set the same, the timer function is not activated.
TR09:AC timer-zone is for A/C (Heating) When TR09 is set to Enable, two different time periods for each day from
Sunday to Saturday. Typically Heating control is by from the system (by remote) so Heating timing is not required.
If every day’s time-zone setting is to be the same, you do not need to set day by day, just go to
Change Monday to Tuesday, and change “No” to “Yes”, then Tuesday’s time-zone setting will be same as Monday.
Use the same method to change Wednesday, etc.
If the unit is manually turned on by the user at the keyboard before the automatic turning on by the timer, this timer
ON program is implemented and unit will be turned off automatically when the time setting reaches the next
programmed off time. (The same applies to manually turning off)

Weather compensation
Heating – Weather compensation curve setting
Note this function is not appropriate in all applications
Users: Seek professional advice before attempting to set weather compensation
There are two methods for temperature control: fixed and changeable temperature. Fixed temperature is a fixed value
and directly set by the user from the settings area. Changeable (Compensated) temperature is determined by the
values of ST02, ST06 and the actual outdoor temperature measured by the OT sensor probe.
The Changeable (Weather compensated) function is selected using SF04:
When SF04: ENABLE COMPENSATION = NO, it is fixed temperature;
When SF04: ENABLE COMPENSATION = YES, it is weather compensated changeable temperature.
Set temperature at heating = ST02 + ST06 *(20-OT).
● ST02 is the indoor temperature that the user requires to feel comfortable.
● ST06 is the heating compensation coefficient curve factor that you select for the heat pump to work with.
Increasing the ST06 set point will increase the compensation temperature and RT will increase relatively. ST06 is
adjustable in a range from 0.6 to 3.0 Degrees.
● OT is the current outside temperature.
The calculated temperature can be used for the control reference, but the maximum data must not exceed ST14
For example:
If you set the heating compensation coefficient ST06 = 0.5 Deg, ST02 = 20Deg
1.) When outdoor temperature is 0℃, the control temperature is ST02 + ST06 *(20 - OT) = 20+0.5*(20-0 ) =30℃;
2.) When outdoor temperature is -10℃, the control temperature is
ST02 + ST06* (20-OT) = 20+0.5* (20- (-10) )=35℃;
3.) When outdoor temperature is –20℃, the control temperature is
ST02 + ST06* (20-OT) = 20+0.5* (20- (-20) )=40℃;
Calculated result as above could be checked from curve below.

With a drop of the outdoor temperature, the control temperature becomes higher to meet the larger heating
requirement.
With the increase of the outdoor temperature, the control temperature becomes lower, so that the heat pump works
at a lower pressure reducing energy consumption.

Cold weather conditions
●When the room temperature is too low, you could increase ST06.
●When the room temperature is too high, you could decrease ST06.
Warm weather conditions
●If the room temperature is too low, you could increase ST02.
●If the room temperature is too high, you could decrease ST02.
NOTE: The temperature of a room with floor heating requires a long time to stabilize. After making
any ST02 ST06 adjustment, wait 24 hours to assess before making further adjustments.
