tion, the electric power consumption of the

circulator pump is reduced further: the energy

(power) used by the pump decreases according

to the pressure level and flow rate. With this

setting, the pump guarantees optimal perfor-

mance in most heating systems, thereby being

particularly suitable in single-pipe and two-

pipe installations. Any noise of the water flow

in the pipes, valves and radiators is eliminated

by reducing the head. Optimal conditions for

thermal comfort and acoustic well-being.

Programs C (3 lower 4 upper) (ΔP-C) - Con-

stant curve (orange LED).

The circulator

pump maintains the pressure level (head)

constant as the system heat demand decreases

(flow rate reduction). With these settings, the

circulator pump is suitable for all floor systems

where all the circuits must be balanced for the

same drop in head.

MIN-MAX Program (Blue LED).

The pump

is distinguished by adjustable operating curves

by positioning the selector in any point between

the Min and Max positions, thereby satisfying

any installation requirement (from a simple

single-pipe to more modern and sophisticated

systems) and always guarantee optimum per-

formance. The precise working point can be

selected in the entire field of use by gradually

adjusting the speed.

Real time diagnostics:

a lit LED (in various

colours) provides information regarding the

pump operating status, see fig. 1-25

Possible pump release.

The pump block is

indicated by a fixed red LED switching on. Turn

the selector up to the MAX position, discon-

nect and reconnect the power to restart the

automatic release process. The pump will then

activate the procedure that will last a maximum

of 15 minutes and the LED will flash upon each

restart. It then turns blue for a few seconds and

goes back to red if the attempt to restart is not

successful. Once the process is complete, set

the selector back to the desired curve and if

the problem has not bee resolved, perform the

manual release procedure as described below.

- Disconnect the power to the boiler (the LED

switches off).

- Close the system flow and return and let the

pump cool down.

  -  Empty the system circuit via the relative cock.
  - Remove the motor and clean the impeller.
  - Once unblocked, remount the motor.
  -  Fill the primary circuit; restore boiler power

and set the desired curve.

Attention:

there is a burns hazard due to high

fluid temperature and pressure.

Burns hazard

from coming in contact.

1.23 CIRCULATION PUMP.

Boilers in the “Hercules Condensing ABT 32 3

ErP” series are supplied with 2 types of circulat-

ing pumps. Set operation modes according to

one's installation requirements.
•

Boiler circulator pump.

The circulating pump

is not equipped with speed selector. To change

operation mode, parameter “Pump sp.” in the

“Configurations” boiler menu must be changed.

Pump release.

If the pump should be blocked

after a long period of inactivity, it must be re-

leased. Loosen the front cap, making sure that

the liquid that escapes cannot cause injury/

damage to persons/objects and turn the mo-

tor shaft very carefully using a screwdriver so

as not to damage the latter. Once the pump is

released, close the vent cap.

•

Direct and mixed zone circulator.

The pump

is ideal for the requirements of each central

heating system in a domestic and residential

environment. In fact, the pump is equipped

with electronic control that allows to set ad-

vanced functions.

Adjustments.

Turn the selector and set it on

the desired curve to adjust the circulator pump.
