1.9 Day/night mode
The day/night mode is used to determine the temperature set points. The mode is automatically
switched on using parameters (P350..P351).
1.10 Set point link
The temperature set point can be linked to another cell (P805]. The controller then uses the same
temperature set point as the cell to which it is linked.
1.11 Blocking
If blocking is activated, all the control functions are stopped. Blocking can be activated during real-
time time periods (P701..P716) or with a digital input. If required, the blocking can be ignored for
automatic ventilation (P720).
1.12 Alarms
The controller has adjustable temperature alarms. Using parameters (P601..P618), it can be defined
for each phase how the alarms must function: absolutely and/or relatively compared to the current
set point, with which alarm delay and with which actions.
Using a digital input, an external alarm can be sent to the controller.
1.13 Counters
The controller has the following free-running counters. These counters can be read and manually
reset from the control.
·
Cooling actions/pulses
