Installation Manual

Install Heat Link
2. Understand the cables
Find the call-for-heat circuit in the
heating system.
The circuit may run directly from
the thermostat to the boiler or pass
through a junction box.
If there’s a combi boiler with no
junction box, the Heat Link will be
connected directly to the boiler’s
control circuit.
You may need to test each cable
to understand its function.
Make sure you connect the
correct cables to the Heat Link
to avoid blowing a fuse.
