5.1 Activation options of pump outlets
Pump 0.1 – 7.2, pump 1
The following settings are possible at the hydraulic modules as well as at pump 1 on the core module with pump
outlets 0.1 – 7.2.
▪ Pump without control line)
Set when a standard pump is run at the respective output. This is controlled at the 230V output using pulse packets.
▪ HE pump without control line
Set when a high efficiency pump without control line (e.g. Grundfos Alpha, WILO Yonos Pico, etc.) is run at the
respective output.
▪ Field pump / PDM
There is a permanent power supply of 230V at the output for the high efficiency pump. The pump is controlled using
pulse duration modulation at the respective PDM output.
▪ Solar pump / PDM
Here again, the pump is controlled by means of pulse duration modulation at the respective PDM output. In this case,
however, the characteristic line is inverted and can only be used for specially marked high efficiency solar pumps.
▪ Field pump PDM +valve
The signal for the field pump is emitted at the PDM output. If the signal exceeds 2%, the 230V output is switched on. If
the signal is below 2% for more than 4 minutes, the output is switched off again.
▪ PDM sol.pump +valve
The signal for specially marked high efficiency solar pumps is emitted at the PDM output. If the signal exceeds 2%, the
230V output is switched on. If the signal is below 2% for more than 4 minutes, the output is switched off again.
▪ Field pump / 0–10V
▪ Solar pump / 0–10V
▪ Field pump 0–10 +valve
▪ Sol. pump 0–10V +valve
The same functions that apply with PDM apply to the parameter values with 0-10V. The only difference is that instead of
pulse duration modulation, a 0-10V signal is used to control the pump.
▪ Switch valve
When set to “Isolating valve” the output is activated either with 0% or 100%. This setting value is only available in the
“Water” or “Boiler 2” menu.
HKP0
The following applies to pump outlet HKP0 at the core module:
▪ Relay output
▪ Speed control is not possible
