A17 Stand-by heating
The stand-by heating keeps the cylinder water warm when no request
is pending. The heating takes place if the safety chain is closed at
intervals according to parameter C16 for the interval time A17 and
according to parameter C17 for the on time A17.
C16 Interval time A17
The C16 parameter defines the length of the pause time between the
phases of the stand-by heating (active only if A17 = Yes).
C17 On time A17
The C17 parameter defines the length of the heating period for the
stand-by heating (active only if A17 = Yes.)
E1 Xp-PI-Controller
Boosting PI-controller = 100/E1 [Xp = 0 - 100%]
E2 Tn-PI-Controller
Reset Time PI-controller [Tn = 0 - 255 sec]
E5 Base Relay
The base relay provides a potentialfree two-way contact at terminals
28, 29 and 30 (rated load: 250V/8A) (see page 59).
It is activated if certain operational conditions apply. The operational
condition “collective fault” is preset.
It is possible to associate another operational condition with the base
relay circuit, also see Section: “Summary Table of Parameters” on
Page 35, “Parameter E5.”
E6 1. Transmitting Relay
The switching function of this relay is factory set to “Essence Injection”
and should not be modified.
The relay provides a potentialfree two-way contact at terminals 31, 32
and 33 (rated load: 250V/8A).
