How to use the PWM 0/10V outputs on °CALEON Clima to control a zone valve, dehumidifier or fan coil

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.

How to configure speed control of high efficiency pumps with 0-10V or PWM

1) Wire the cables to the controller
Pump cable on left side: blue wire to – brown wire to V1 (black wire is redundant)
Power supply on right side: brown wire to R1 blue wire to N

2) Go to Special Functions – Pump Settings V1
Select type of pump (get this information from pump manual or type label). Set pump signal (get this information from pump manual or type label). If the pump does not support “Solar” or “Heating” standard, you can select from other pre-defined signal profiles. The parameters automatically adapt to your selection. To be sure about the signal settings, compare “Show signal” to the data sheet of the pump

3) Activate speed-control
Check the other speed-control parameters

Done!
