4 Installation
4.1 Preparation
1. Ensure you have the following parts:
No. Name Quantity Remarks
1 Control box 1
2 Screws 3 M4 x20
(For mounting on the wall)
3 Anchors 3 For mounting on the wall
4 Connective wires group 2 For connecting the sensor
5 5m connective wires group 1
Table 1
2. Prepare the following tools:
No. Name Quantity
1 Switch box 1
2 Wiring tube (insulating sleeve and tightening screw) 1
Table 2
3. Select installation location. DO NOT install the 24V INTERFACE near
flammable liquids or gases such as gasoline or hydrogen sulfide. Doing so
creates a fire hazard.
4.2 Installation Process
1. Remove the cover of the 24V INTERFACE. Remove the four screws of the
24V INTERFACE with a screwdriver. Lift the top cover as shown in Fig. 3.
Figure 3
Minimum free space required around the product is 7" (180 mm).
2. Mount the back plate of the 24V INTERFACE on the wall. Mount the 24V
INTERFACE vertically and fasten the back plate to the wall with 3 screws
(M4 x20) and anchors (see Fig. 4).
Figure 4
Back plate
Screws (M4×20)
Place the unit on a flat surface. Be careful not to distort the back plate of
the 24V INTERFACE by over tightening the screws.
When installed vertically, the direction of the arrow must be up.
3. Wiring: please refer to following pages for model specific wiring procedures.
4. Reinstall the cover and fasten screws (see Fig. 5).
Figure 5
System Configuration
Thermostat should be configured for use with a conventional
system.
The remote controller, wiring controller, central controller and
WiFi cannot be used with this control box at the same time.
Only the Swing and LED function can be used.
