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

2-wire system:
Mechanical thermostats usually only use 2 wires,
without the neutral wire hence the name
2-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.

neutral wire is required. This setup is known as
3-wire system.
