Note
Sensor PASC (AMBIENT)
The temperature is the minimal outdoor
temperature to be expected and will be
used for the ambient temperature (PASC)
algorithm only. It will set the correct duty
cycle for an optimized and energy saving
operation. If the ambient temperature is
below this set point, the relay is 100% ON.
Select the temperature by using
the + / – keys.
Select the type of nVent RAYCHEM heating
cable used in your installation, connected to
heating zone 1.
Other system can be used if the heating
cable type is not known or listed.
Select the type of nVent RAYCHEM heating
cable used in your installation, connected to
heating zone 2.
Other system can be used if heating cable
type is not known or listed.
Assign the correct pipe diameter per
heating zone 1 and/or 2.
You can change the value from DN 10 up
to DN 125.This has impact in the ambient
temperature sensing mode to define the
correct duty cycle.
Note: In case of multiple pipe sizes per
heating zone, select the bigger size of the
pipe network.
To determine the low temperature limit.
When the value is reached, a warning will
appear on the screen. The buzzer tone will
be active.
The relay will be continuously ON and will
not interrupt the unit's functioning. The info
status main screen will show the actual
pipe temperature.
To determine the high temperature limit; A
warning will appear on the screen when the
value is reached.
The relay will be continuously OFF and will
not interrupt the unit's functioning.
Value range:
+2°C to +90°C /Standard NTC sensor
