Switch-off when outdoor temperature is exceeded - lowering mode
ON/OFF
Switch-off condition activate/deactivate. (fs = OFF)
NV
Set outdoor temperature for switch off. (fs = 5°C) Setting range: -20 to 99°C
HYS
Switching hysteresis (fs = 2.0 K) setting range: 0 to 25 K
The switching hysteresis has an upward effect.
Example
: with a switch-off temperature of
NV
5°C and a hysteresis of 2.0K the pump is switched off at 7°C as the temperature increases
and switched on again at 5.0°C as the temperature falls.
AVT
Averaging time of the outdoor temperature for the switch-off the pump in minutes.
Compensation of fluctuating outdoor temperatures. This value is identical to the
(mean time) AVT value under the switch off condition OTNOFF.
(fs = 30 min) Setting range: 0 to 255 min
AV
Actual average value for the outdoor temperature.
Mixer behaviour
Specifying how the mixer should behave after the pump has been switched off:
Close, continue control, stand still unchanged, open.
Factory setting: Close
