Functions
5-1
Switch stand-
by heating
Stand-by heating is enabled or not (0= off, 1=on).
5-2
Interval
stand-by
heating
Parameter 5-2 determines the interval time between
heating phases when stand-by heating was enabled.
5-3
On-time
Stand-by
heating
Parameter 5-3 sets the heating on-time when stand-by
heating was enabled.
5-4
Basic relay
allocation
The basic relay features potential-free NC and NO con-
tacts across terminals 28,29 and 29,30, respectively
(contact capacity is 250 VAC/8A). The base relay pro-
vides a potentialfree two-way contact at terminals 28, 29
and 30 (rated load: 250V/8A).
The relay is activated when a certain operating status is
achieved. Parameter 5-4 allows for allocating a logical
function, i.e. the relay is energized when a certain oper-
ating status occurs. Factory setting is „0“ defined as „col-
lective fault“It is activated if certain operational
conditions apply. The operational condition “collective
fault” is preset.
The following allocations are supported:
(0) Collective fault: Relay is energized in case of any
fault.
(1) Stand-by: Relay is energized when the unit is in
stand-by.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: Relay is energized when input signal
creates no demand.
(3) Humidifying: Relay is energized when humidifying is
active.
(5) Remote off: Relay is energized when safety interlock
was opened under software by means of the building
control system.
(30) Filling off: Relay is energized when filling is not
active.
(31) Filling on: Relay is energized when filling.
