6.5 Defining the actuating signal limit
The maximum heating output can be limited using the actuating signal limit.
The limit is set as a percentage of the maximum value.
The controller output limit for the heating output is designed to prevent
excessive temperatures on the surface of the heater. Excessive heater tem-
peratures may degrade the heat transfer liquid or damage the device.

6.6 External control
6.6.1 Activating external control, deactivating internal control
If you want the device to regulate to another control variable, you must set
a new control variable. The old control variable is then deactivated automati-
cally.
Connect a Pt100 temperature probe for monitoring the temperature in the
external consumer to the 10S interface on the constant temperature equip-
ment. The standard indicator for the external measured temperature T
ext
is
always the preset external control variable. If the remote control displays a
different temperature, this must be set explicitly.
If the external control is activated, the constant temperature equipment
regulates the temperature to the external temperature value T
ext
and not to
the bath temperature T
int
(bath thermostat) or the outflow temperature T
int
(circulation thermostat).
