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.
