Basic relay
allocation
The base relay provides a potentialfree two-way con-
tact at terminals 28, 29 and 30 (rated load: 250V/8A).
It is activated if certain operational conditions apply.
The operational condition “collective fault” is preset.
The following allocations are supported:
It is possible to associate another operational condition
with the base relay circuit, also see Section: “Summary
Table of Parameters” on Page 56, “Parameter E5.”
(2) No demand: input signal creates no demand.
(3) Humidifying: humidifying is active.
(5) Remote off:
(30) Filling off: .
(31) Filling on: filling.
