6 Description and operation
6.1 Pump description
Pump (Fig 1)
The circulating pump is fitted with a wet (canned rotor)
motor.
The circulating water service pump Stratos ECO-Z 25/1-5 is
specially designed for use in conjunction with domestic/
drinking water service systems. It is by material selection and
design, corrosion proofed against any residual, parts in
domestic/drinking water.
For thermal insulation the pump housing is lagged with an
insulation shell.
The motor housing is with an electronic control modul
(Item 1) capable of maintaining the pump generated differ-
ential pressure constant at a preset value between 1 and 3 m,
or 1 and 5 m. Pump capacity is thus matched to the changing
load demand which is particularly significant when using
thermostatic control valves.
The essential advantages and benefits are:
• no bypass relief valves required,
•powersavings,
• reduction of flow noise.

English
Installation and operating instructions Wilo-Stratos ECO 9
Control mode (Fig 2):
Variable differential pressure (Δp-v): The differential pres-
sure setpoint levels being proportionally increased between
½H and H over the permissible flow range. The pump-gener-
ated differential pressure will thus be controlled to the
respective level.
The pump automatically responds to the night setback of
the central heating installation by electronic evaluation from
a temperature sensor. The pump will then switch to the min-
imum speed. On renewed boiler heat up the pump will switch
back to the previously adjusted setpoint level. The night set-
back control can be switched off (Fig. 1, Item 2):
•auto: Night setback ON, control operation to the preselected
setpoint value and automatic, temperature-activated night
setback (additional power savings).
• : Night setback OFF, control operation to the preselected
setpoint value.
Factory setting: Night setback OFF.
NOTE:
In the case of insufficient heating/cooling capacity of the
installation (too low a heat transfer) it must be checked
whether the night setback control is on. In this case it must be
switched off.
Operating elements (Fig 1):
• Dial knob for the differential pressure setpoint (Fig. 1, Item 2).
• Setting range:
• Stratos ECO 25(30)/1-3: Hmin = 1 m, Hmax = 3 m
• Stratos ECO 25(30)/1-5: Hmin = 1 m, Hmax = 5 m
• Stratos ECO-Z 25/1-5: Hmin = 1 m, Hmax = 5 m

tion and discharge ports of the pump in order to facilitate a
possible pump exchange. They must belocated in such a way
to prevent valve spindle leakage from spilling onto the con-
trol module (upper valve turned sideways).
• Install pump free of stress and with the motor shaft horizon-
tally located. For module locations refer to Fig. 3. Other
arrangements on request.
• Directional arrows on pump body and the insulation shell
indicate the direction of flow.

8Starting-up
WARNING! Risk of burning!
Note the acute danger of the pump becoming very hot,
depending on the operating conditions of the pump or sys-
tem respectively (fluid temperature). Danger of burning
when touching the pump!
8.1 Initial start-up
Ensure that the pipe system is properly filled and air-vented.
The pump rotor space is automatically vented after a short
running period. Short-term dryrunning will not do harm to
the pump. If, however, manual venting of the pump may
become necessary (not apply for air-venting pump) the fol-
lowing procedure is to be adopted:
• switch-off pump,
• close discharge isolating valve,
WARNING! Risk of scalding!
Depending on fluid temperature and system pressure there
is the possibility of hot water in liquid or gaseous state
suddenly erupting under great force when opening the
vent plug. Note the severe danger of scalding!
• break through the perforation, centrically the name plate and
open the vent screw carefully,
• protect electrical parts from released water,
• carefully move and push pump shaft with a screwdriver,
CAUTION! Risk of damage to the pump!
There is the possibility, depending on the system pressure,
of the pump jamming with the vent plug open. Before
switching on the pump refit and tighten the vent plug.
• refit and tighten vent plug,
• reopen discharge valve,
•switchonpump.

8.2 Adjusting the pump capacity
• Select desired control mode (refer to chapter 6.1).
• Preselect pump capacity (head) at the dial button according
to requirements (Fig. 1, Item 2).
• If head requirements are not known it is recommended to
begin with a 1,5 m setting.
• If the heating capacity proves insufficient increase head set-
ting step by step.
• Reduce head setting step by step if the heating capacity is
too high or noise generation is excessive.
• Select night setback mode; switch either to On or Off (refer to
chapter 6.1).
9 Maintenance
