1Summary

1.1 Brief description

Smart Thermostat RDS120 is designed to control the heating/cooling system in

apartments, single family homes, dormitories and other residential-type as well

as light commercial spaces. Apart from traditional operations performed directly

on the hardware unit, remote operations that use a mobile app are also allowed

for your convenience.

2Installation

●The thermostat is designed for wall mounting.

●The recommended height is 5 feet above the floor.

●Do not mount the thermostat in recesses, shelves, behind curtains or doors,

or above or near heat sources.

●Avoid direct exposure to sun and drafts.

●Seal the conduit and/or wall opening, as drafts can affect sensor readings.

●Observe maximum ambient conditions.

1. Switch off power to the heating/cooling system at the breaker or system

power switch.

2. Remove the old thermostat from the wall with wires still connected.

3. Using the provided wire decals , label the existing wire connections. It is also

helpful to take a picture of the current wire connections for subsequent

reference.

4. Disconnect all the labeled wires and then remove the old thermostat.

NOTICE! Do not discard the old thermostat in the trash if it contains

mercury. Contact a thermostat recycling organization, for example,

www.thermostat-recycle.org, for safe disposal of the old thermostat.

5. Check whether more wires are needed to bring 24 Vac power from the

HVAC equipment to the thermostat. If yes, prepare the wires and label them

accordingly.

6. Seal the conduit and/or wall opening to prevent entrance of cold or warm

air and ensure accurate temperature readings by the internal sensor.

7. Install the mounting plate and power unit.

–If you are mounting the thermostat directly on a wall, screw the small

mounting plate enclosed with the thermostat snugly on the wall using a

screwdriver, making sure that the mounting plate is placed correctly (the

part with the upward arrow is placed on the top), and then screw the

power unit on the mounting plate.

–If you are mounting the thermostat on a conduit box, install the metal

mounting plate enclosed with the thermostat tightly on the conduit box

(making sure that the upward arrow part is placed on the top), attach the

plastic trim plate to the mounting plate, and secure by screws.

Tip: Before installing the power unit, it is highly recommended the

labeled wires be connected to the terminals snugly according to the

thermostat terminal designations (you may also refer to the picture taken

in Step3). Do not overtighten.

NOTICE! a) The following illustration is for reference, which may be

different from the wiring for your application. b) The thermostat only

works with low-voltage wires (AC 24 V), so it is very important to

make sure that the thermostat is not connected to high-voltage

wires.

8. Attach the front module horizontally, making sure that each side of the front

module fully aligns with that of the power unit, and then press the corners

following the order described in the following illustration until you hear a

click sound. Note that you need to discharge the static electricity on your

body before mounting the front module. For example, touching the wall

could help on Electro-Static discharge (ESD).

9. Switch on power to the heating/cooling system. The thermostat should be

powered up as well.

See Mounting instructions for more information.

●Observe local codes regarding wire type, overcurrent protection and ground.

●For HVAC systems with a single transformer, the RH-RC jumper must remain

in place. If separate transformers are used for heating and cooling systems,

remove the RH-RC jumper.

●24 Vac supply line must have a circuit breaker with a rated current of no

more than 4 A. The total current rating should not exceed 3.3 A. For 24 Vac

US installations, use Class 2 transformers.

●Disconnect from power supply before removing the front module and the

mounting plate.

3Setup wizard

When the thermostat is powered up for the first time, a setup wizard displays to

guide you through the following procedures:

●Setting a display language

●Setting an administrator password

●Setting up a network connection and choosing the network connection type

●Selecting an equipment type and setting up the details

●Configuring date

●Specifying a name to the location where the thermostat is installed
