Installation of the electrolytic capacitor
In order to reduce the phenomenon of temperature spikes being read from the zone sensor, a 220uF/25V low impedance
electrolytic capacitor, connected in parallel with the sensor cable, should be installed. When installing the capacitor,
always pay particular attention to its polarity. The ground of the element marked with a white strip is secured to the right
terminal of the sensor connector, as seen from the front of the controller and depicted in attached images. The second
terminal of the capacitor is attached to the terminal of the left connector. We found that this solution completely
eliminates any potential distortions. However, it is worth noting that the basic principle is to correctly install the wires in
order to avoid interference. The wiring should not be routed near sources of electromagnetic field. Should such a situation
exist, a filter in the form of a capacitor must be included in the system.
WARNING
If pump manufacturer requires an external main switch, power supply fuse or additional residual current device
selective for distorted currents it is recomemnded not to connect pumps directly to pump control outputs.
To avoid damaging to the device, an additional safety circuit must be used between the regulator and the pump.
The manufacturer recommends the ZP-01 pump adapter, which must be purchased separately.
