External functions
7.4.1
Central control technology off (external OFF)
The input Central control technology off (external OFF) is used for the controlled deactivation of the IQntrol DOS MODBUS via the
swimming pool filter system’s central control. As long as the contact is open, there is no dosing, no heating of the basin water, no
alarm message given.
7.4.2
Clean water external
A flow monitor with a potential-free contact can be connected to the input Clean water external. As long as the contact is open,
there is no dosing, no heating of the basin water.
7.4.3
Temperature control
The device is equipped with a temperature control. This temperature control can be used to regulate the basin water
temperature. If the basin is heated by means of a flow-through heat exchanger, it must be ensured that the associated heating
circuit pump may only be activated when the filter system is in operation!
Please remember that the regulation of the basin temperature can only be guaranteed if the filter operation times are set to an
appropriate duration.
In order to achieve a more precise measuring result, the sensor must be installed by means of an immersion sleeve in the
swimming pool's piping upstream of the filter.
ATTENTION!
Immersion sleeves that come into contact with the swimming pool water must be corrosion-proof.
ATTENTION!
Please observe the safety notices regarding the topic of temperature control!
