Once a new controller or sensor has been installed the installer will need to assign which zones will use which sensor.
It is not the last controller used is the sensor…

Chewed wiring? Obvious points of urine, nests, droppings etc etc.....

Make sure the roof trusses are sufficiently spaced apart to fit the Indoor unit. Trusses are usually working on 600mm centres (that's around 560mm between trusses). 85 sq mtrs will…

Icing up of the condenser can happen when temps get below 7'C, but there is a defrost cycle that should kick in to remove any ice.
Premature icing up can happen…

Something else to think about is the warranty.
All the Hi-wall split brands we sell specifically say -
Warranty is void unless the system is used for human comfort.
In other words wine…

Your correct the ESP series have model numbers that begin with SRD.
I think Johnny_Franklin may have made a typo
The SRD160 is a 3 phase unit. The 'c' on the end…

Makes sense to me. That's what I would do.

Hi Johnny_Franklin
As you will see from my previous posts, I am a fan of Actron Air.
Super performance, super reliability and high energy efficiency, Aussie made.

You might want to check out this YouTube vid from Actron Air. Looks like a perfect system for your scenario. Actron Air are Australian Made and have a 18kW single…

I don't believe I wrote that you were wrong, I just don't agree.
For instance the round outlets we use do not push the air down at all. The air air…

B STAR, I don't agree with your statement.
Square or round is a personal preference. They work equally as good at distributing the air…

Have you considered the Actron Air ESP+.
This is precisely what they are are made for. The ESP+ can run down to one outlet if you want and save a fortune…

Less than 12 Months? Should still be under warranty!

Amongst other things the ActronAir ESP+ has a variable indoor fan that can wind down to supply air to just one room! Daikin cant do that! Oh and save up…

The basis of any air conditioning system is to start with a heat-load on the home.
Amount of windows, which way is west, how well insulated and what will be the…

What B STAR says is absolutely correct!

Certainly is'nt rocket science!
As long as you follow a reliable duct design.

Sorry they are model numbers for SRV190 (19kW) and SRV230 (23kW).
Yours being a 15kW this size should easily go down to one outlet.
Cheers

Mmmm maybe the system needs to be put through the learning mode again?
If the system is a 190 or 230 you may still get too much air as the system…

To go to an ESP+ there can not be any constant zones. There must be a zone motor on everything.
To rectify sensing problems extra sensors can be fitted.
Actron Air are…

With the Actron Air ESP+ the system needs to be commissioned.
During commissioning the system will need to be put through a learning mode.
When completed, the system fan will wind all…

No worries Thirsty!

By the way, love the…

Can you hear the crickets?
That says it all.
Daikin are quite expensive, but there are plenty of brands better than TECO.
Such as Samsung,…

We've done some math on this a couple of years ago.
We found that the initial cost difference to go from a constant compressor to an inverter would take between 9…

Here Here!
First and foremost I am a Fridgy.
We come across so many systems that are short of refrigerant and more often than not they have been installed by an electrician.
As…

We have done this a number of times.
A round outlet (Paltech or Meton) to 250mm duct requires a 360mm hole in the ceiling
If the duct size is 300mm you will…

Just me being pedantic
But the Actron Air uses a digital scroll compressor not an inverter compressor.
The Scroll Compressor uses an unloader to control capacity.
The Inverter compressor uses stepped speed control…

What Iceman said, 100%

We generally have a slab poured (organised by the owner), particularly when the unit is so big.
From your pictures, the workmanship is nothing to be proud of.
