Z11AS
Reverse rinsing actuator
for fully automatic filter cleaning
Product specification sheet
Application
The Z11AS automatic reverse rinsing actuator provides fully automatic cleaning for all Honeywell reverse rinsing filters, filter combinations, water supply units and water distributor units. The
reverse rinsing intervals are adjustable in sixteen steps between
four minutes and three months. The Z11AS has an emergency
running function in the event of power failure (only when batteries
are fitted) and offers the possibility of manual operation of the
reverse rinsing function. Connection options are available for
differential pressure switching, remote control and remote monitoring.
Special Features
• Pushbuttons give easy setting of intervals
• Pushbutton for manual operation of reverse rinsing
• Digital indicator of time interval set
• Digital indicator of number of reverse rinsing cycles carried
out
• Facility to indicate time remaining before next programmed
reverse rinsing cycle
• Reset button enables resetting of counter
• Settings are maintained even when electrical power fails
• Set during manufacture to 45 day interval
• Can be set to 16 different reverse rinsing intervals
• Automatic battery
• Manufactured with integral electrical suppression
• Additional PG 9 cable entry for connection of remote operation, remote monitoring or differential pressure control
• Can be connected for differential pressure switch, remote
operation or remote monitoring
Range of Application
For fully automatic reverse rinsing of Honeywell filters, filter
combinations and water supply unit.

Z11AS Reverse rinsing actuator
Method of Operation
The Z11AS opens or closes the ball valve according to the set
time interval. The opening of the ball valve causes a differential
pressure within the filter which activates the reverse rinsing
function. The ball valve closes again at the end of the reverse
rinsing period. Four batteries (not supplied) provide back-up
protection. The batteries close the ball valve if power fails during
reverse rinsing function, thus preventing unwanted water loss.
Options
For filters and filter combinations HS10, F76, F76C, FK76C,
FKN76C, FN76C and FN09 (up to 1996).
Z11AS-1/2A = 230 V, 50/60 Hz, 10 W

Additional connection options
The Z11AS can be remotely actuated by:
a) A volt-free switching circuit
b) Via an open-collector output.
In both cases the minimium holding period is one second.
Reverse rinsing occurs when the inputs “Start” and “U+” have
been separated.
The reverse rinsing function can be actuated according to
demand using the DDS76 differential pressure switch with
voltage free switching. It is recommended that the differential
pressure be set to 1.0 bar. Operation occurs when the inputs
“Start” and “U+” have been separated, that is, after the differential pressure has fallen below the set value. Through this it is
guaranteed that a maximum quantity of water is available for
reverse rinsing. If reverse rinsing starts immediately irrespective
of the duration of the differential pressure signal, then the inputs
should be connected instead to “U+” and “SIGN”.
The DDS76 differential pressure switch can only be used
where F76 / F76S / F76S-F fine filters are also installed.
For remote monitoring of the open/closed position of the ball
valve the installation of a building management system with 0 to
10 V input is recommended. The maximum current is 10 mA.
With a current of 0.5 V the ball valve is open and with a value
between 5 V and 6 V the ball valve is closed.
