Description
Activate/deactivate the measuring and set the mA output to 4mA,
and set the digital relays to default.
Turn off the digital relays and also the timers. Only running with mA
output.
Defrost start in % where the digital start relay is activated and the
mA is lock when it get to the defrost start level. E.g. 50% stops the
mA output at 12mA.
Defrost stop temperature when the digital stop relay is activated
and the sensor delay starts running, mA only function is 19mA.
Sensor delay time is used for securing frost after defrost before the
sensor start measuring again. The start and stop relay is deactivated
after timeout.
The total length of the active part of the wire between the fins (only
the wire between the fins is active).
Distance between fins in mm.
