temperature detection collection object (RadOvrTDetCol); this collection object is a
common node for any/all RadOvrTDet input object(s).
The RadOvrTDet objects are analyzed using an OR statement. If one or more
objects detect over temperature, the binary result object (RadOvrTDetRs) switches
from 0 to 1, causing the radiator to shut off at equipment protection priority.
Electric power usage: The nominal electric power usage of the electric radiator is
provided for energy monitoring and coordination with other devices. The following
equation calculates the radiator's electric power usage when on (RadElPosVal >
0%):
RadElPwr = RadElPosVal * NomElPwr (zero power is used when radiator is off)

Description
Parameter
Default value
Enable overtemperature detector input
▶ Enable input, when a radiator heat over temperature
detector (binary input) is present. When radiator heat
over temperature detector is closed, the radiator l
device mode will turn Off at priority (4:Protection 1).
When radiator heat over temperature detector is open,
the radiator device mode will be released to 15:
Automatic mode 6).
