Compatibility
The HUB Controller was built to directly replace the existing heating controls. It measures room temperature
and allows the user to modify operation and set point temperature. It can be installed in any household with
an individual heating system.
The HUB Controller can replace:
Mechanical thermostat Time clock or programmer

2-wire system:
Mechanical thermostats usually only use 2 wires,
without the neutral wire hence the name
2-wire system.
3-wire system:
When heating controls directly connect to a higher
load (e.g. directly to boiler, pump or 2+ valves), the
neutral wire is required. This setup is known as
3-wire system.
If there is neither a mechanical thermostat nor a programmer or a timer clock controlling the heating
system, the HUB Controller may still be compatible. Please call +353 1 901 0367 and we’ll evaluate the
system.
Power requirements
Voltage: 230 V AC +/-10%
Frequency: 50 Hz
Maximum load: 50 mA w/o neutral, 2 A w/ neutral
Load types and ratings
2-wire system: max 2 valves (25 mA each)
3-wire system: load max 460 W (boiler&pump)
The HUB Controller is compatible with 99.3% of all boilers.

Replacing a mechanical thermostat
The HUB Controller can replace any mechanical
thermostat, regardless of the fuel type.
Mechanical thermostats usually only use 2 wires and the
HUB Controller has been designed to work specifically in this
situation.
It has a rechargeable battery that is powered by the existing
2 wires on the wall. This patented technology allows the
HUB Controller to charge itself without requiring a neutral

with any heating system, without any need to change the
existing wires.

Replacing a time clock
In a heating system without a thermostat, the HUB
Controller can replace a time clock or a programmer.
Because the existing time clock/programmer is directly
controlling a boiler or a pump, there is always a neutral
wire. In this case, the neutral wire must be connected to
the N connector on the bottom.

Installation steps
Step 1
Establish that the existing heating controls are in fact
controlling the heating. Turn o the power to your
heating system at the mains. To ensure the wires do
NOT have power running to them, use a mains tester.
WARNING! HIGH VOLTAGE
Step 3
Tighten the HUB base plate to your wall using the
screws provided. Don’t forget to use the washer to
make sure it’s level.
NOTE! Overtightening the screws may interfere
with proper operation.
Step 2
Remove your existing thermostat or time clock or
programmer. If required, test each wire to determine
its function. Label and safely disconnect the wires.
Step 4
Identify your wiring, and then see the appropriate
wiring diagram. Connect the L to the top, V1 to the
centre, and, if applicable, N to the bottom. If this is
your first installation, you may want ot check the
troubleshooting section for more info.
L Live wire
V1 Control wire
N Neutral wire
LV1N
WARNING! Installing the wires incorrectly will
damage your HUB.
Step 4a
If applicable, set your programmer or time clock to
always on.
Turn on the mains electrical power.

Step 5
Connect the HUB Display to the base plate aligning
the display with the right side of the base plate.
Then push the le side into place until it ‘clicks’. The
HUB Controller will start automatically, so follow the
on-screen instructions to proceed to setup.

Setup
Aer the installation is complete, the HUB Controller will start automatically.
Step 1
Select the network
The device will begin to scan for wireless networks.
Once the HUB has discovered all the available networks, select the home’s Wi-Fi from the list.
Step 3
Download the app
In order to connect the HUB to a mobile phone, you
need to install the HUB Controller app on the phone.
While the HUB is connecting, download the HUB
Controller app from the online store.
Step 2
Enter the network details
Once the Wi-Fi network has been selected, type in
the password to access it.
Step 4
Add a mobile user
Once the connection has established, the HUB can
now be connected to a mobile phone. Go to Menu
and click on Pairing. The device will display 7
digits. Type that code into the mobile phone app to
pair the phone with the device.
NOTE: The HUB Controller will operate on its own
without being connected to Wi-Fi. However, a Wi-Fi
connection is required to control the device from
the HUB Controller mobile app.
