Shut down mode

AQUA24TF/D has an input (terminals 15-16) which is wired to a 
potential-free contact in the fan motor relay. The contact should 
be closed when the fan is running. When the fan is stopped the 
AQUA24TF/D will switch to shut-down mode which means that the 
temperature at the frost protection sensor is held at 25°C.

Night setback
A potential free closure between terminals 6 and 12 will give a fi xed 
night setback of 3K.

Settings

AQUA24TF/D is on delivery set to values suitable as starting values 
for balancing the system.
Final settings must be tried out when the system is commissioned. 
Factory settings FS in brackets.

Setpoint  0 - 30°C. Setpoint for the main controller. (FS = 20°C).
CF 

1 - 15. Cascade factor. (FS = 1). The value signifi es the 
immediate change in the duct controller setpoint for a 
1K step change in room temperature. (Cascade control 
only).

Min 

0 - 30°C. Minimum duct temperature. (FS = 15°C). (Cas-
cade control only).

N.B. 

When running single sensor temperature control (not cas-
cade control) CF must be set to 1 in order to get stable 
control. 
Min is inactive.
