DT4 / DT4S

Set temperature difference
Adjustment range:

1.5

... 50.0 K [3.0

... 90.0 °Ra]

in steps of 0.5 K [1.0 °Ra]
Factory setting: 10.0 K [20.0 °Ra]

DT4 / RIS4

Rise
Adjustment range:

1 ... 20 K [2 ... 40 °Ra]

in steps of 1 K [2 °Ra]
Factory setting: 2 K [4 °Ra]

The heat exchange function is used for transporting
heat from tank 2 to tank 1.
The reference sensor (heat source) for the heat ex-
change function for tank 2 is sensor S5 (TST2T). The
reference sensor (heat sink) for tank 1 (TST1T) is S3.
It is used as a reference sensor for the differential
function and for the maximum limitation.
Additionally, minimum and maximum temperature
limitations and the corresponding switch-on and
switch-off differences can be set for the independent
temperature differential control. Both switch-on and
switch-off temperature differences DT4O and DT4F
as well as the set temperature difference DT4S and
rise RIS4 are valid.

Note

The heat exchange function is only available
in arrangement 2 and 4.

Maximum temperature limitation for the heat
exchange

DT4 / MAX4O

Switch-on temperature
Adjustment range: 0.5 ... 95.0 °C [31.0 ... 200.0 °F]
in steps of 0.5 °C [1.0 °F]
Factory setting: 60.0 °C [140.0 °F]

DT4 / MAX4F

Switch-off temperature
Adjustment range: 0.0 ... 94.5 °C [30.0 ... 199.0 °F]
in steps of 0.5 °C [1.0 °F]
Factory setting: 58.0 °C [136.0 °F]
If the adjusted value MAX4O is exceeded, the relay
will be switched off. If the temperature falls below the
adjusted value MAX4F, the relay will be energized.

Minimum temperature limitation for the heat
exchange

DT4 / MIN4O

Switch-on temperature
Adjustment range: 0.0 ... 94.5 °C [30.0 ... 199.0 °F]
in steps of 0.5 °C [1.0 °F]
Factory setting: 5.0 °C [40 °F]

DT4 / MIN4F

Switch-off temperature
Adjustment range: 0.5 ... 95.0 °C [31.0 ... 200.0 °F]
in steps of 0.5 °C [1.0 °F]
Factory setting: 10.0 °C [50.0 °F]
If the temperature falls below the adjusted value
MIN4O, the relay will be switched off. If the adjusted
value MIN4F is exceeded, the relay will be energized.
