Local
motor isolators
may be required connected to the relay
output.
l1 and C to be bridged.
Splitting of the additional program output with connections for two
additional isolating valves AD1 and AD2.
With the help of two extra relays it is possible to connect the output of
the additional program to two unit dependant isolation valves if
required.
Relay outputs RE and FL may be treated similarly.
Inputs:
WM
= water meter
WA
= wait
RS
= regeneration start
These
inputs
are
activated
by

Connection
of
a
dosing
pump:
The pulse duration must be set (section 7 of the programming
notes).
Powered
output
:
A dosing pump, of the correct voltage may be connected directly
across terminals 3 and 26. Terminals 4 and 25 must be linked.
Potential free output :
A dosing pump may be connected directly across terminals 25 and 26.
