Nest Gen3 Thermostat (UAE & U.S versions) general requirements
- Nest Thermostats are designed to work with 24V US spec AC systems. They require installation of a conversion kit as well as bypassing of AC control board in order for them to work with 220V UAE AC systems
- Nest Thermostats can be retrofitted to work on single and 3 fan speed modes
- Single fan speed mode requires the presence of 4 wires to thermostat location
- Three fan speed mode requires the presence of 6 wires
- Thermostat locations with 3 wires, requires the installation of an additional wire saver module to add the 4th wire for single fan speed.
- Less than 6 wires at a thermostat location requires the pulling of a new set of 6 wire panel cables for three fan speed activation
- New ACs with inverter compressor or DC current fan motor require different installation method. The process involves installation of a brand specific interface that interprets Nest signal back to the AC control board plus pulling of CAT6 cable.
- Nest E thermostat can only support one fan speed vs 3 fan speed for the Nest Gen3
Non-compatibility: cases where Nest cannot be installed
- Window type AC units
- VRV type ACs
- Where ACs are connected to a BMS or wired smart home system
- Chilled water systems with modulating actuator motor (1-10v). These require replacement of actuator with on/off model
- UK and European spec Nest thermostats are designed to work with boilers and water heaters and are not configured to work with AC systems
Specific compatibility guidelines
Apartments:
- As a general rule, apartments located within towers are typically served by a central chiller, as such would have 6 wires
- In some newly build apartments with modulating actuator motors, there would a requirement to replace actuator motors with standard on/off models. This can only be established post inspection. Cost of actuators motors varies between AED 350-500 per unit. In very rare cases, valve assembly would also have to be replaced (cost AED 1500 per unit)
District cooling:
- AC units within areas with district cooling such as the Palm, Jumeirah Islands, JLT, Motor City and Sports City would have thermostats with 6 wires
Villas: (in non district cooling areas)
a) LG:
- Found in majority of Emaar villas across Springs, Meadows and Arabian Ranches as well as Al Furjan
- All units have 3 wires to thermostat location
- Requires installation of an additional module (add 4th wire) for single fan speed
- Three fan speed requires pulling of 6 wires. Smaller capacity units have single stage fan that requires installation of fan transformer (AED 390)
- Installation of Nest thermostat on new LG ACs with modulating compressor and DC fan motor is not yet supported.
b) OGeneral:
- Found in many Emaar villa communities.
- All units have 3 wires to thermostat
- Requires installation of an additional wire saver module that provides 4th wire for single fan speed.
- Three fan speed installation requires pulling of new 6 wire cables
- New OGeneral ACs with modulating compressor and DC fan motor. Require installation of a bespoke Nest interface/module approx cost (AED 900) per module
c) York & Daikin:
- Both York and Daikin units would have 4 wires through to thermostat location
- York prevalent in The Villa project. Daikin is installed in all Arabian Ranches 2 communities
d) Trane:
- Older units would have 8 wires through to thermostat location
- Newer units with LCD type thermostat would have 2 wires going to thermostat location
- Prevalent in Jumeirah Park and other Nakheel communities
e) Carrier:
- Mexican spec : 4 wires
- Egyptian spec: 5 wires (found in Damac Hills), requires wire saver for 3 fan speed.
- Egyptian spec: 4 wires (found in Arabella Mudon), ACs have inverter compressor and DC fan motors. Requires interface module.
f) Midea:
- Found in Mira Oasis and Maple Villas in Dubai Hills
- Units on ground floor are standard 5 wire AC current fan motor. Requires wire saver for 3 fan speed operation
- Units found on first floor are inverter compressor/DC current fan motor. These require pulling of CAT6 cable and installation of interface module
g) Samsung:
- Comes in two variants 4 wire AC fan motor (Legends Villas) and 2 wire inverter compressor (Sidra, Dubai Hills)
- Samsung ACs in Sidra require specific interface (AED 950) pulling of 6 new wire cable and installation of conversion box
h) Rheem : 6 wires found in Mira and 5 wires found in Lantana. ACs in Lantana can only support 2 fan speed as medium and high speeds are looped on AC.
i) American breeze: 6 wires found in some older Emaar villas in Meadows and Lakes as well as Jumeirah Islands
j) Mitsubishi: All Mitsubishi units require pulling of new wires as well as installation of an interface (provided CN90 connector is present on PCB). Found in older villas of non-free hold communities
k) Honeywell: Very rarely installed in villas. Would typically have 6 wires
l) Trane: 8 wires, found in some Jumeirah Park villas. Villas in newer districts would have 2 wire Trane AC in which case new 6 wire cable have to be pulled
Good afternoon,
I would like to enquire about the installation service for the nest thermostat, i have a ogeneral ac system for a bedroom and would like to know if its compatible and can install a nest thermostat…. What is the quotation? And does it include the installation only and the thermostat is charged separately… I live in abu dhabi, so is it possible to install…. Thanks
Hi Noora,
Yes the Nest can be installed on OGeneral AC. There would be two installation options, single fan speed including wire saver module (OGeneral has 3 wires and Nest needs 4 wires) cost AED 725. Three fan speed (low, medium and high) would require pulling new 6 wire cable. Cost wise, installation would be AED 650 + AED 300 to pull new wires. The Nest Gen3 is AED 950 per unit.
We do undertake installations in Abu Dhabi, a transport fee would apply
Please let us know if you require any additional information
hello, I live in a new bldg in JVC, with an LCD thermostat.
someone installed my nest gen 3, but I cannot change the fan speed and also cannot use the airwave function.

is it possible to fix it to be able to use the 2 different fan speeds that the stock thermostat had?
thanks!
Hi Georgios
Yes it is possible to make it 3 speed by pulling another 2 wires.

Hi,
I am looking to install a Nest thermostat in a new house in Dubai Hills Estate.
The current system is Midea. Is it possible to install a Nest here?
Hi Ben,
Installation of Nest with 5 wire Midea AC is possible. There would be two installation options; 2 fan speed using the existing 5 wires, for 3 fan speed installation we would also need to install a wire saver module that provides the required 6th wire.
In terms of costings, the Nest Gen3 thermostat is AED 899+VAT and comes with 2 years warranty. 2 fan speed installation AED 595+VAT including cost of conversion parts. 3 fan speed installation would be AED 595+175 for the wire saver so total installation AED 770+VAT
Please let us know if you require any additional information

Am considering the Nest E or the 3rd Gen. Live in Mira Oasis and have a Midea control panel. Not entirely sure on the number of wires or the cost of installation?
Hi Lee,
Mira Oasis has two different type of Midea ACs. One located on ground floor is standard AC with on/off compressor. Installing Nest E on that AC is AED 495+VAT for single fan speed. Units upstairs have an inverter compressor which requires a different installation method using an interface. This type of installation is considerably more expensive
Regards
HomeIQ Support
Thanks for the information. So would a Nest E still work on the upstairs units? And when you say considerably more expensive, what price range are we talking about. Sorry, last question, would a 3rd Gen provide more than one fan speed?
Hi does nest system work for much older non freehold Dubai villas (old complex With old ahu units on roof) , and if so what benefit would it give over a one or two year period?. Thanks
Hi Alison, some of Dubai’s older villas would have a US 24V ACs so the Nest can be installed without need for conversion box or bypassing the AC control board. In terms of savings for an average villa, you can expect a saving off electricity bill of around 20-25%.

Hi, I live in Damac Hills. We have Carrier AC system with 5 wires with ABCDE configuration to the thermostat. Can a Nest system be installed and would this be single fan speed or 3 fan speed? Is single fan speed still effective for general use?
Hi Paul,
We genuinely appreciate your inquiry.
Nest will work with your carrier air conditioner with three fan speed by using a third-party adaptor, known as interface module, it is programmed in accordance with the PCB board to perform the same functions and also serve as a voltage converter, because your system only operates at less than 12 volts while nest works at 24 volts. This interface is necessary in order to use the smart thermostat to its full potential
Thank you
Hi,
I live in Dubai Creek Harbour Residence Tower with chilled water. I think the installed thermostats are Honeywell T6865 Series. Is it possible to replace it with a smart thermostat – which one can I use and how much would it cost?
