Description Function E2
Sensor difference to E1 (
Sensor for setpoint outdoor temperature controlled (
Measurement value e.g. Measurement value e.g. for limit indication, display in Info
menu "E2 Actual".
For activation of a second control circuit
(only possible in certain modes (
Temperature control, pre-settings and sensor selection correspond to mode
Pressure control condensers
Pressure control for condensers with input for refrigerant
Pressure control air conditioning, pre-settings and sensor selection correspond to
mode 4.01
Air volume control
Air velocity control, pre-settings correspond to mode
Designation
No function
Relays remain always de-energized
Operating indication (factory setting for "K1", non inverting).
Operation without fault, reports enable "OFF"
Fault indication (factory setting for "K2", non inverting).
Pulled up in operation without fault, with release "OFF" not dropped out.
Drops out in case of line and device fault and external fault at the digital input. Depend-
ing on programming in event of sensor failure.
External fault separate with message at digital input (factory setting if terminals
bridged)
Limit modulation
Exceeding or falling below limits for modulation
Limit "E1"
When over or falling below limits for input signal "E1"
Limit "E2"
When over or falling below limits for input signal "E2"
For modes as controller higher
Setpoint Offset
Deviation between actual value and setpoint to high
Group control (Group 2)
Switching on fans depending on modulation
Group control (Group 3)
Switching on fans depending on modulation
Group control (Group 4)
Switching on fans depending on modulation
For modes as temperature controller with additional functions
Heating function
Switch ON point: temperature = Setpoint +/- Offset
Switch OFF point: Temperature around hysteresis over switch ON point
