Installation and operating instructions Wilo-Yonos PICO OEM
Recommended for systems with fixed system resis-
tance requiring a constant volume flow.
Constant speed (I, II, III):
The pump runs uncontrolled in three prescribed fixed
speed stages.
Q
The pump venting function is activated via the function
key and vents the pump automatically.
The heating system is not vented.
A manual restart is activated via the function key and
deblocks the pump as required (e.g. after a prolonged
standstill during the summer).

4 Intended use

The high-efficiency circulators in the Wilo-Yonos PICO
series are exclusively designed 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).
• Water-glycol mixtures* with a maximum of 50 %
glycol.
* Glycol has a higher viscosity than water. If glycol is
added, the delivery data of the pump must be corrected
to suit the mixing ratio.
NOTE
Only add ready-to-use mixtures to the system.
Do not use the pump to mix the fluid in the
system.
