Venting
Fill and vent the system correctly. If the pump does not vent automatically:
- Activate the pump venting function via the operating button: press and hold for
3 seconds, then release.
• The pump venting function is initiated and lasts 10 minutes.
• The top and bottom LED rows flash in turn at 1 second intervals.
- To cancel, press and hold the operating button for 3 seconds.
NOTICE
After the restart, the LED displays shows the previously set values of the
pump.
Electrical connection
May only be installed by qualified technicians.
- The current type and voltage must correspond to the specifications on the rating plate.
- Maximum back-up fuse: 10 A, slow-blow.
- Only operate the pump with sinusoidal AC voltage.
- Note the switching frequency:
• On/off switching operations via mains voltage ≤ 100/24 h.
• ≤ 20/h for a switching frequency of 1 min. between switching on/off via mains voltage.
- The electrical connection must be made via a fixed connecting cable equipped with a connector device or an
all-pole switch with a contact opening width of at least 3 mm.
- Use a connecting cable with sufficient outer diameter (e.g. H05VV-F3G1.5) to protect against leaking water
and to ensure strain relief on the threaded cable connection.
- Use a heat-resistant connecting cable where fluid temperatures exceed 90 °C.
- Ensure that the connecting cable does not make contact with either the pipes or the pump.
Connecting the mains cable
- Cable assignment:
• 1 yellow/green: PE
• 2 blue: N
• 3 brown: L
- Press down the locking button of the 3-pin pump plug and connect the
plug to the plug connection of the control module until it snaps into place.
Intended use
High-efficiency circulators in the Wilo-Para series are exclusively intended for circulating fluids in hot-water heating
systems and similar systems with constantly changing volume flows.
Permitted fluids:
- Heating water according to VDI 2035 (CH: SWKI BT 102-01) or ÖNORM H 5195.
- Water-glycol mixtures* with a maximum of 50% glycol.
*Glycol has a higher viscosity than water. If admixtures of glycol are used, the pumping data of the pump must be
corrected to match the mixing ratio. Intended use includes observing these instructions and the specifications and
markings on the pump.
