INSTRUCTION
Controller for supply air temperature or room
temperature control, one output 0-10V.
AQUA24A1/D is primarily intended for control of supply air tempera-
ture or room temperature in HVAC systems. It has one output for
either heating or cooling. AQUA24A1/D is built for DIN-rail mounting
with all settings accessable on the front.
Installation
Mount the controller on a DIN-rail in a cabinet or other enclosure.
Protection class
IP20
Ambient temperature
0...50°C
Sensors
Main sensor
For supply air temperature control the main sensor is placed in the
incoming air duct after the heater.
For room temperature control the main sensor is placed at a
representative location in the room.
Wire the sensor according to fig.1 if the built-in setpoint is to be
used, otherwise according to fig.2 or fig.3 depending on which
external setpoint is to be used.
Limiting sensor, cascade control
When running room temperature control the AQUA24A1/D may be
wired as a cascade controller with the main sensor in the room and
a limiting sensor in the incoming air duct. Any temperature deviation
in the room results in a shift in the duct controller setpoint. The size
of the shift is determined by the cascade factor CF. The duct
temperature can, when running cascade control, be both maximum
and minimum limited.
Wire the limiting sensor according to fig.4.
N.B.TG-K360 must be used as limiting sensor.
INSTRUCTION
Other wiring
Supply voltage and output
Supply voltage: 24 V AC ±15% 50...60Hz
Power consumption: 5VA maximum.
Terminal 13 = system neutral.
Terminal 14 = phase.
Output: 0-10V DC 1mA maximum.
Terminal 9 = signal neutral
Terminal 10 = Y1 heating or cooling
Damper limiting
By using a TBI-100 potentiometer it is possible to maximum ot
minimum limit the output signal to a damper actuator.
Wire the TBI-100 according to fig.5 (minimum) or fig.6 (maxi-
mum).
Inverter
In the AQUA24A1/D there is a separate inverter (terminal 17=in,
terminal 18=out). It is not internally connected to the controller
but can if needed be wired to either output.
Shut down mode
AQUA24A1/D has an input (terminals 15-16) which is to be
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 AQUA24A1/D will switch to shut-down mode
which means that the output is held at 0V and the integrators
are shut down. On restart the starting output is determined by
the P-offset only. If the offset is zero the startup point is at Y1 =
0V.
Set Point Control
The setpoint can be shifted -15K - +15K from the set value by
applying a 0-10V DC signal to the SPC input (terminal 8). 5V
gives zero shift. If the terminal is left open it is internally held at
zero shift.
