1) Indicates whether input E7, E8 is open or closed (control signal « yes » or « no »)
2) Integral action time (T n ) = 0 s means: P-control for the respective control sequence
Integral action time (T n ) > 0 s means: PI-control for the respective control sequence
3) Only when the RWI65.02 is configured for an electric air heater battery.
During the overrun time, the fan runs at speed I. On completion of the selected overrun time, the fans will
be switched off and the outside air dampers closed
4) Period of time during which the plant - after arrival of a pulse (> 2 s) at E7 or E8 - shall operate.
When set to 0 min, the plant is switched on or off the moment the signal arrives at E7 and E8 (external
time switch) (only in Automatic mode and when the internal time switch has switched off or is permanently
deactivated)
5) Period of time during which the plant may operate with 100 % recirculated air (after plant startup)
6) If operating level 1 is locked (data point value = On), it is not possible to change any values for two
minutes after closing the front door (exception: summer-/wintertime changeover).
Enabling by reopening the front door
7) The display shows the actual program number (software version)
8) Must be set if the controller is equipped with a communication module. If no communication module is
used, the value set has no effect on the RWI 65.02
9) Counted are the number of fan operating hours.
The reading can be reset either to zero or to the former value. Proceed as follows:
1. Press function button 10 (line 10)
Press setting button « − » if the meter shall be reset to zero, or setting button « + » if the meter
2.
shall
be reset to the former value
3. To confirm the resetting, press function button 10 again.
10) Active only if coded for hot water heating coil!
ð
00.00 Circulator kick interval is disabled
ð
00.05 - 24.00 Circulator kick occurs for 30 s according to the selected interval time
ð
Auto Circulator is activated for 30 s every 24 h, or runs continuously when the
outside temperature is < 5 °C; the minimum circulator running time (data
point 48) is maintained
ð
Cont Circulator continuously on
11) The setting of a minimum running time avoids too frequent activation / deactivation of the circulator
12) To avoid unnecessary faulty alarms, the fault status signal can be delayed
13) After a power failure and subsequent power restoration, it may be necessary to bring the controller back
into operation with a certain delay. This is to make certain that after a power failure, all plant elements
connected to the same mains network will not be switched on at the same time (peak loads)
14) To protect the plant, the second fan speed is disabled at very low outside temperatures. In that case, only
the first fan speed will be enabled. To avoid unnecessary fan speed changes when outside temperatures
greatly vary, a hysteresis of 2 K is used
