Thermostat Installation FAQs:
What’s a C wire?
A common wire (C wire) is an extra cable that supplies 24V electricity to a thermostat. Most smart thermostats and some programmable thermostats require them in order to enable certain features.
Are thermostat wires AC or DC?
Thermostat wires are 24V AC.
Where should I install a thermostat?
Thermostat installation guidelines recommend installing thermostats 1.50m above the floor. Thermostats should not be installed in recesses, shelving, behind doors or curtains, directly above heat sources, or in direct sunlight. Most thermostats are situated in the hallway or lounge of a property.
Who installs thermostats?
Licensed electricians, HVAC technicians, and many plumbers can install, repair, or replace thermostats.
What do I need to install a smart thermostat?
In order to install a smart thermostat, you’ll need:
A compatible heating system (check with the thermostat manufacturer before buying)
2.4GHz WiFi
A smartphone, tablet, or smart hub
Most smart thermostats require a C Wire or a nearby power socket
Is it difficult to install a smart thermostat?
If you have the required wiring already in place, a smart thermostat can be installed by anyone with a basic knowledge of DIY. Most thermostat manufacturers have detailed installation guides on their website, or on youtube.
If you don’t have the required wiring, we’d recommend calling a professional HVAC installer, who can get you set up quickly and professionally.
Do you need WiFi to set up a smart thermostat?
If WiFi is not available, or if you’re installing a smart thermostat in a new build, it is still possible to install and set up smart thermostats through the unit itself. Most smart thermostats function like regular programmable thermostats without WiFi.
