5.11.1 Setpoint toggle (day/night operation)
Controller setpoints can be enter as both standard and alternative values. Setpoint toggle allows of
switchingbetweenthestandardandalternativesetofsetpoints.Thiscanbeperformedbyfourmethods:
External: By voltage applied to 230 V- Digital Input 2 (Terminal D21/D22, factory setting) by a switch or
timer.Alternatively,withanappropriateparameterisationofthedigitalinputs(menu6-2-4),thesetpoint
switchcanbecarriedoutviadigitalinput1(terminalsD11/D12)ordigitalinput4(terminalsD41/D42).The
functionofthedigitalinputscanbeconfiguredviatheparametersInv.D1toInv.D4(menu6-2-4).Ifmore
thanoneinputhasbeenparameterisedwiththesamefunction,thenthisfunctionisactiveassoonasa
signalisappliedtooneoftheseinputs.
Internal:
Bysettingtoggletimesontheinternalclock.(onlyactivewhentheparameterToggleinterv.(menu3-3)is
setto”--”).
Toggle interval:
For special applications e.g. in service counters, it is necessary to carry out a regular setpoint toggle. By
means of the parameter Toggle interv. (menu 3-3) it is possible to conduct this cyclical setpoint toggle every
10to60minutes.Thefunctioncanbeswitchedoffwhentheparameterissetto”--”.Furthermore,the
parameter is only visible when the parameter Toggle Setp. (menu 3-3) is set to INT.
Example: If the parameter Toggle interv. is set to 15 minutes, then the controller uses the standard setpoint
and the alternative setpoint alternately for 15 minutes respectively.
CAN bus:
With the use of system centre or a suitable store computer (version 4.24 and higher) the setpoint can also
be controlled from the system centre / store computer via CAN bus. Further information on setpoint
switchingcanbefoundinthesystemcentres/storecomputer'soperatingmanualinthechapter”Special
Inputs”.
DANGER
Warning - hazardous electrical voltage! Danger of electric shock! BEFORE and AFTER
connection it must checked that the 230 V AC digital inputs are off load!
The controller and connected voltage carrying components remain supplied with power!

Internal toggle times for the setpoints are ignored if the parameter Toggle interv. is assigned values
between 10 and 60 minutes.
