1) Connect external relay to 0-10V / PWM output of °CALEON Clima
2) Connect external relay to desired external device (e.g. zone valve, dehumidifier, or fan coil)
3) When °CALEON Clima is fully installed, go to Menu – Expert – Caleon – Manage Functions
4) Select desired function
5) Configure settings for that function.
Some devices like 0-10V actuators or high-efficiency pumps can be configured in the same way, but even without the need for an external relay in between.
