General Description (figure 6)
Ecocirc circulation pumps are shaftless spherical motor pumps with
energy-efficient, electronically commutated permanent magnet
technology (ECM technology) for use in hot water heating systems, heat
pumps, solar systems, air conditioning systems, closed cooling circuits
and industrial circulation systems.
12
For technical reasons, the contact surface between the rotor and the
ceramic ball bearing in spherical motor pumps is very small. For this
reason, even if they have not been in operation for a long time, such as
after the summer, only a small amount of torque is required to start the
pump. Ecocirc pumps do not require (and thus do not have) a
release/vent screw.
Ecocirc pump has two standard and two auxiliary operation modes:
Constant Speed
=
The user can set the speed of the pump by
turning the knob into any position between
1 and 7, 7 is the fastest. The preset speed
remains constant, independently from the
flow.
Proportional Pressure
=
The user can set the maximum strength of
the pump by turning the knob into any
position between 1 and 7, 7 is the
strongest. The pump automatically
decreases its speed at low flow, thus
providing energy saving.
Automatic Air Purge
=
The user can purge the trapped air from
the pumphouse.
Standby
=
The user can keep the power consumption
low (<1W) when pump operation is not
needed.
Instructions to change between operation modes:
- To change between standard operation modes (proportional pressure
and constant speed) the user shall turn the knob until the low end
position and turn the knob back to the desired setting within 5 sec.
Pump indicates mode change by switching the color of the knob LED
(proportional pressure is blue and constant speed is white). In both
cases the light is constant.
- To activate the air purge function the user shall turn the knob until the
low end position and wait at least 5 seconds before turning the knob
back to the desired setting. For air purge indication see section 9. After
air purge cycle finishes (approximately 10 minutes) the pump will return
to the previous standard operating mode.
Note: if user leaves the knob at the low end position pump will enter
standby mode after the air purge cycle finishes.
- To enter standby mode without going through the entire air purge cycle
the user shall first activate the air purge function, then, turn the knob to
13
any other setting and immediately turn it back to the low end position.
LED has a steady light. To return to a standard operation mode the user
shall turn the knob to the desired position. Note: returning from standby
changes the pump operation mode from Constant Speed to Proportional
Pressure and vice-versa. The user can reset the desired mode as
described in the first paragraph.

Heating system power range up to approx. 50 kW
(radiator heating systems up to approx. 500 m² living
space, underfloor heating systems up to approx. 200 m²
floor space). The power of the Ecocirc pump must not be
adjusted by applying phase trimming ("pulsing") to the
supply voltage.

Installation Advice
The installation of a stop valve upstream and downstream of the pump is
recommended so the pump can be replaced at a later time without the
need to completely drain the system.
7.
Installation
The unit may not be installed in areas where there is a
danger of explosion and may not be used to pump
flammable liquids.
Figure 3: Only install in dry, frost-proof rooms in one of the permitted
fitting positions.
Figure 4: The use of type WD-B thermal insulation shells, available from
the manufacturer, is recommended when a thermal insulation
of the pump is required. When using other materials, leave the
motor housing uninsulated, otherwise the electronics may
overheat and the pump may automatically switch off.
Screw connections for installing the pump in the system are not included
in the scope of delivery, but they may be ordered as accessories from the
manufacturer.
Use new gaskets (included in the scope of delivery) when installing the
pump.
The customer must take appropriate isolation measures and provide
appropriate acoustic insulation to reduce possible noise transfer.
7.1
Electrical connection (see figure 7)
The unit may only be connected by an authorized
electrician. The pump is equipped with a factory installed
cable.
In case of changing the connection, it must be made as
ATTENTION
shown in figure 7. The pump requires a separate circuit
breaker installed on the phase with a rated value of 10A.
The socket must be positioned in such way that no water
can drip onto it even in the event of damage to the piping.
16
7.2
Getting started
The pump must not run dry as this can result in the
ATTENTION
destruction of the bearing in a very short time. Fill it with
liquid before first start-up.
Before starting, the system must be:
- Rinsed thoroughly to prevent the presence of foreign objects and
impurities which could block the pump.
- Fully filled with the pumped media (water or water-glycol mix).
- Completely purged of air.
- To help to reach this, the pump has a built-in automatic air purge
function. See instructions for activating the air purge function in
section 2 page 4.
- The air purge function can be activated any time during operation
when the presence of air is suspected in the system.
- The air purge function can be activated several times in a sequence if
necessary.
- Audible flow noise indicates that there is still air in the pump.
7.3
Typical setting
The corresponding values are derived from the hydraulic calculation of
the system. If this calculation is not at hand, then the following speed
settings can be used:
Standard single-family home
(approx. 140 [email protected] 50 W/m2 = 7 kW)
Ecocirc…-4
2-3
Apartment block
(approx. 420 [email protected] 50 W/m2 = 21 kW)
Ecocirc…-6
2-3
If the temperature differential between the flow and the return is too large,
increase the power; if the temperature differential is less than expected,
reduce the power even further. (Guideline values: underfloor heating: 8–
10 K; radiator heating: 15–20 K).
17
8.
Maintenance/Disassembly
Pumps are subject to wear. If the pump is blocked (see section 9) or
grinding noises are audible, check the pump and replace it if necessary.
Procedure:
- Disconnect the pump from the mains.
- Shut off supply and drain lines. If there are no shut-off
devices, drain the system so that the fluid level is
beneath that of the pump.
- Loosen the union nut by hand or with an appropriate
tool (such as a strap wrench) and carefully pull the
motor out of the pump housing.
Residual water may leak out of the rotor cavity. Prevent
ATTENTION
the pump's electrical connection from getting wet.
For figure 5:
- Carefully but firmly pull the rotor / impeller upward by hand and remove
it.
- If necessary, remove foreign bodies and impurities/deposits with
appropriate agents. Reinsert the rotor / impeller.
- The bearing is worn if the rotor / impeller cannot be freely moved or if
wear marks are visible. In this case, replace the rotor, the pump motor,
or the entire pump.
9.
Operating signal light / Troubleshooting / Warranty
Work on electrical parts may only be performed by
authorized electricians.
When the electrical connection to the pump is properly made and the
pump is powered, a white or blue light (depending on the actual operation
mode) is constantly lit in the knob of the Ecocirc pump.
Mode selection: turn the knob to the end position below 1 then turn it
back within 5 sec.
Constant Speed: white light; Proportional Pressure: blue light

Note regarding excessive temperatures:
In order to protect the electronics from temperatures that are dangerously
high, the electronic control system monitors its own temperature. If the
measured temperature is too high the pump speed is reduced. If the
19
temperature rises above a safety limit, the pump will shut itself off. The
pump will automatically restart after cooling down.
