W62, sensors in the raw water circuit on the plant/system side

Availability of option
This option is available for the following S120 Cabinet Modules:
● Heat Exchanger Modules
Description
With this option, a flow monitor and a temperature sensor are installed in the intake of the
plant-side raw water circuit.
In addition, a TM150 Terminal Module is installed to evaluate the temperature signals.
The signals are connected at the TM31 or the TM150 Terminal Module.
This means that the flow and temperature can be monitored.
The temperature alarm limit can be parameterized in the Control Unit.
The flow signal is parameterized at the sensor, and is evaluated by the TM31 Terminal
Module.
