2.1.2 ON/OFF Control
In the operation modes mentioned below, the control of the consumer load is realized by switching it
completely on or off.
2.1.2.1 Brine defroster / GHX flap control
The temperature sensor is installed
upstream
of the components brine defroster or GHX regulating flap.
The control of the brine defroster / GHX regulating flap depends on the configured temperature thresholds
X1 /X2 (see appendix 1 and appendix 2):
ON: T ≤ X2 or T ≥ X1
OFF: T ≥ X2+H and T ≤ X1-H
DIP- 1
ON
DIP-2,-3,-4 OFF
T
- Actual value of
intake air temperature upstream of brine defroster / GHX flap
H - Hysteresis
X1 - Setpoint ″ upper switching threshold ″
X2 - Setpoint ″ lower switching threshold ″
2.1.2.2 2-level control for defroster heater
The temperature sensor is installed
downstream
of the component defroster heater. The control of the
defroster heater depends on the configured temperature threshold X2 (see appendix 1 and appendix 3):
ON: T
≤ X2
OFF: T ≥ X2+H
DIP-2 ON
DIP-1, -3, -4 OFF
T
- Actual value of
intake air temperature downstream of the component
H - Hysteresis
X2 - Setpoint ″ lower switching threshold ″
