Cooling circuit control

Parameters in Shutdown conditions sub-menu
SHUTDOWN CONDITIONS and mixer action
The controller allows the following shutdown conditions for the cooling circuit pump:
if T.room
Act. < set
Diff. on
Diff. off
Shutdown when the required room temperature (+ offset value) is
reached
Start differential for the effective set room temperature
Stop differential for the effective set room temperature
if T.flow
Act. < min.
Diff. on
Diff. off
Shut down if the flow temperature falls below the minimum value
Dew point / flow min. + Offset flow dew pt
Start differential for minimum value
Stop differential for minimum value
if T.outside
Aver.off < min.
T.outside min.
Diff. on
Diff. off
Shutdown if the average outside temperature T.outside AVo falls
below the adjustable value T.outside min.
Required threshold value
Start differential for T.outside min.
Stop differential for T.outside min.
if cooling circ pump =
off
Mixer
Mixer action after shutdown of the pump (unless Enable cooling
circuit = Off):
Available for selection: Close, Open, Unchanged, (continue to)
Regulate
if enable mixer =
off
Mixer
Mixer action when Enable mixer = Off:
Available for selection: Close, Open, Unchanged
➢ None of the parameter values have an adjustable hysteresis. The switching thresholds are
each divided into a start differential and a stop differential.
CALENDAR
The Calendar op. mode input variable selects the operating mode of a Calendar function.
In the Calendar set room t input variable, the set value (=set room temperature) 1, 2 or 3 assigned
to the operating mode must be specified. However, any other source is permitted as well (e.g. a
calendar set room temperature from another controller via the CAN network). This set value takes
priority over the Set room temperature input variable.
If no calendar set temperature is defined (unused), the calendar operating mode will have no effect
on the function.
If two or more calendar operating modes are active simultaneously, the operating mode with the
highest priority (see Calendar function) is applied together with the corresponding set value.
If no calendar operating mode is active (Inactive (0) is displayed in the input variables), the calendar
set room temperature defined in the Calendar function for Inactive will be displayed in the input
variables. That value will not be applied in the cooling circuit function, however.
