INSTRUCTION
Settings
AQUA24A1/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 comissioned.
Factory settings FS in brackets.
Setpoint Setpoint for the main controller. 0...30°C. (FS 20°C).
Pd
Proportional band for the duct controller. 2...100K.
(FS 18K). The value signifies the necessary change in
duct temperature to shift the output from 0V to 10V.
Id
Reset time for the duct controller. 1.7...20 minutes.
(FS 8 minutes).
CF
Cascade factor. 0.5...15. (FS 5).
The value signifies the immediate change in duct con-
troller setpoint for a 1K step change in room tempera-
ture. (Cascade control only).
Ir
Reset time for the room controller. 3...33 minutes
(FS 20 minutes) (Cascade control only)
Min
Minimum duct temperature. 0...30°C.
(FS 15°C). (Cascade control only).
Max
Maximum duct temperature. 20...60°C.
(FS 40°). (Cascade control only).
N.B. When running single sensor room temperature control (not
cascade control) CF, Ir, Min and Max are inactive.
Amplification and reset time are then set as for duct tempera-
ture control using Pd and Id.
