3.1 Control modes and functions
Variable differential
pressure
Δp-v
(I, II, III)
Recommended for two-pipe heating systems with radi-
ators to reduce the flow noise at thermostatic valves.
The pump reduces the delivery head to half in the case of
decreasing volume flow in the pipe network.
Electrical energy saving by adjusting the delivery head to
the volume flow requirement and lower flow rates.
There are three pre-defined pump curves (I, II, III) to
choose from.
Constant
speed (I, II, III) Recommended for systems with fixed system resistance
requiring a constant volume flow.
The pump runs in three prescribed fixed speed
stages (I, II, III).
4 Intended use
The high-efficiency circulators in the Wilo-Atmos 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.

Installation and operating instructions
Transport
inspection Inspect for transportation damage and check complete-
ness immediately after delivery, and claim immediately if
necessary.
Transport and
storage conditions Protect from moisture, frost and mechanical loads.
Permissible temperature range: -10 °C to +50 °C.
NOTE
Only add ready-to-use mixtures to the system.
Do not use the pump to mix the fluid in the
system.
WARNING!
Danger of injury or material damage due to improper
use!
Never use non-specified fluids.
Never allow unauthorised persons to perform work.
Never operate the pump outside of the specified
limits of use.
Never carry out unauthorised conversions.
Use authorised accessories only.
Never operate with phase angle control.

Install shut-off devices upstream and downstream of
the pump to facilitate pump replacement.
Align the upper shut-off device laterally.
When installing in the feed of open systems, the
safety supply must branch off upstream of the pump
(EN 12828).
Complete all welding and brazing tasks.
Flush the pipe system.
Rotating the motor
head Rotate the motor head (2 + 6) before installing and con-
necting the pump.
If necessary, remove the thermal insulation shell.
Hold the motor head (2 + 6) and unscrew
the 4 housing screws (5).
Carefully rotate the motor head (2 + 6).
Observe the allowable installation position (Fig. 2)
and the direction arrow on the pump housing (1).
Tighten (4-7.5 Nm) the 4 housing screws (5).
CAUTION!
Leaking water may damage the control module.
Align the upper shut-off device such that leaking
water cannot drip onto the control module (6).
WARNING!
Risk of fatal injury from magnetic field!
Risk of death for people with medical implants due to
permanent magnets installed in the pump.
Never remove the rotor.

Installing the pump Observe the following points when installing the pump:
Note the direction arrow on the pump housing (1).
Install without tension, with glandless pump motor
horizontal (2).
Place gaskets in the screwed connections.
Screw on threaded pipe unions.
Secure the pump with an open-end wrench against
twisting and screw tightly with the piping
Re-mount the thermal insulation shell, if applicable.

CAUTION!
Insufficient heat dissipation and condensation water
may damage the control module and the glandless
pump motor.
Do not thermally insulate the glandless pump
motor (2).
Ensure all condensate drain openings (3) are kept
free.
DANGER!
Danger to life due to electrical voltage!
Immediate danger to life if live components are
touched.
Before commencing work, switch off the power
supply and secure it against being switched on again.
Never open the control module (6) and never remove
control elements.

Preparation The current type and voltage must agree with the
specifications on the rating plate (4).
Maximum back-up fuse: 10 A, slow-blow.
Only operate the pump with sinusoidal AC voltage.
Note 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 (VDE 0700/Part 1).
Use a connecting cable with a sufficient outer diame-
ter (e.g. H05VV-F3G1.5) to protect against leaking
water and to ensure strain relief at the threaded cable
connection.
Use a heat-resistant connecting cable where fluid
temperatures exceed 90 °C.
Ensure that the connecting cable does not make con-
tact with either the pipes or the pump.
CAUTION!
Pulsed mains voltage can lead to damage to electronic
components.
Never operate the pump with phase angle control.
When switching the pump on or off using an external
control unit, deactivate any voltage pulsing
(e.g. phase angle control).
For applications where it is not clear whether the
pump is operated with pulsed voltage, get the
control/system manufacturer to confirm that the
pump is operated with sinusoidal AC voltage.
Switching the pump on/off via triacs/solid-state
relays must be examined on a case-by-case basis.
