1) Operation Summary- A device which senses temperature of each zone controls operation of each dif-
fuser, so temperature of each zone can be controlled.
2) Specific Operation- If every zone (diffuser) is closed, Comp and outer fan become turned off to
protect compressor.
* Zone controller requires diffuser temperatures and controllers available locally.
Operating Scene- The temperature of all zones are con-
trolled individually (makes energy savings)- Controlled by the signal of every zones induct system (By connecting the thermostat and VAV Diffuser to Main PCB,comp. & fan)
• Diffuser and Thermostat are locallysourced
- Connected to Another Apparatus, Controlit Freely

• Non Spring Return Damper Actuators
By Pass Damper System :-
To maintain an adequate flow of air and static pressure through the HVAC system, a by-pass systemcan be used that is equipped with a motorized damper and a static pressure control.
CAC Accessories 11
Zone Control
When the area dampers open or close, the static pressure control will open or close the by-pass damper soas to maintain the adequate static pressure. Dimensions of the by-pass damper depends on the coolingcapacity of the unit.
Remarks • Turn off the Power before installation or maintenance.

Low Ambient Controller(For Heat - Pump type)
Installation Procedure :- Fixing : - The control should be mounted to control panel within the condensing unit using two screws sup-
plied. Fasten it to any holes on control panel as long as there is enough space to install.
If necessary, drill holes to install on proper position.
Electrical Connections :-
Some condensing units are equipped with two fans. In that case, connect the lead wire of each motor to ter-minal numbers 3 and 4. But some condensing units also require a separate control for each fan.
Heat Pump Models : - When the Low Ambient Control is to be used with a Heat Pump, the condenser fanneeds to run at full speed during the heating mode, and is only modulated duringthe cooling mode.When fitted to a Heat Pump, terminal numbers 6 and 7 should be wired directly tothe reversing solenoid valve ; in all cases both live and neutral side of solenoidvalve should be connected to the control.

Table : Setting Temperatures ; Controlled by rotating P1
Cooling Only Models : - On cooling only units, where a reversing valve is not fitted, terminal numbers 6 and7 Should be left unconnected.
Fitting the Sensor : - Locate a return bend, two or three bends above a convenient liquid line exit from theCondenser. This should ideally be chosen with its temperature closest to that of dis-charge saturation temperature.
Setting the Control : - First check whether switch SW01F is towards pipe or not. If not than slide it towardspipe.
Preset temperature at the condenser outlet can be set by switch S/W P1 and accordingly the fan on /
off temperature will be as follows :
According to preset temp. - 0 or 1 or 2,.........17, you can read the % speed ratiofrom graph. The variation in % speed ratio ischanged by position of switch S/W P2.
Remarks
- Disconnect all power supplies before starting installation or maintenance work.
- The control & sensor are to be safely enclosed within the condensing unit.
- All electrical wiring must be carried out by a competent person, and must followthe local & National Electric code.

However, it may be freely installed in any direction forward or back, and to the sides.• Be sure to leave a 600mm square opening for service and inspection as shown in the diagram below, for
both ceiling - suspended installation and wall-mounted installation.• This unit "does not require drain treatment" as it uses internal foam treatment as low-pressure piping
insulation.• Service direction is the side B and C• The piping for the indoor unit may be led around in direction A• The inclination of side B must be within ±5°C degrees forward or back or to the sides.

Procedure(1) Fix the fumished hanger metal with two screws.(4 locations in
total).(2) Using an insert-hole-in- anchor, hang the hanging bolt.(3) Install a hexagon nut and a flat washer (locally-procured)to
the hanging bolt as shown in the figure in the left, and ift themain unit to hang on the hanger metal.
(4) After checking with a level that the unit is level, tighten thehexagon nut.* The tilt of the unit should be within ±5° in front/back and
left/right.

(3 locations in total).
(2) After checking with a level that the unit is level, fix the unitwith the furnished wood screws.* The tilt of the unit should be within ±5° in front/back and
left/right.
CAUTIONS• Once a screw-hole on the main unit has had a screw hammered in, make sure to either hammer it again
or cover it with alumium tape.(This is to prevent condensation)• Be sure to install the unit with the ceiling-sie up.• Do not install near bedrooms. the sound of refrigerant flowing through the piping may sometimes be
audible.

Connection of Wiring :• Connect refrigerant pipes and connection wires to the appropriate ports maked with matching
alphabets (A, B and C) on this unit.
• Follow the instructions on the wiring nameplate to connect the connection wires of indoor/outdoorunits to terminal board numbers.(1, 2 and 3) Always fix each ground wire separately with a groundscrew.(See the figure below.)
• After completing the wiring, fix the outer coating of wires securely with wire clamps. The wire clampon indoor unit side is furnished. Follow the procedure below to install.
• Refer to the circuit diagram on the control cover inside outdoor unit.
: The terminal board numbers are arranged from top to bottom in order of 1, 2 and 3.

• When the number of Indoor Units to be connected to the branch pipes is less than the number of branchpipes available for connection then cap pipes should be fitted to the surplus branches.
• Fit branch pipe lie in a horizontal plane.
• Header should be insulated with the insulator in each kit.
• Joints between branch and pipe should be sealed with the tape included in each kit.
• Any cap pipe should be insulated using the insulator provided with each kit and then taped as describedabove.
