Emos SARV105 WIRELESS THERMOSTAT  

INTRODUCTION

This thermostat can replace most common residential thermostats and is designed to be used to control heating or cooling system. Unlike ordinary single unit design thermostats, this unit is a new type of thermostat separating the thermostat function into two units. The Receiver serves for wiring connections and heat/cool on/off control. The Control Centre serves as user interface and temperature sensing/control. The two units are linked by RF. The advantage is that users can put the Control Centre nearby and can read/control the temperature of the living area.

Caution

•  The appliance can only be mounted indoors and in areas free from any water or moisture.
•  A suitable fuse with a rating not exceeding 20A should be placed in the power line.
•  Observe the national regulations for wiring.
•  A qualified electrician is recommended for installation and servicing.
•  Read this manual carefully before installing.

LED INDICATORS
There are two LEDs on the Power Control Unit as status indicators:

•  Red LED turns on as long as there is power to the unit. When there is no power to the unit or when power switch on the front cover is put at the OFF position, the red LED is off.
•  Green LED turns on as long as the heating/cooling device is energized.

POWER SWITCH
There is a power switch on the Power Control Unit. When there is no demand to turn on the heating/cooling device, e.g. when you go on holiday, it is recommended to turn the power switch to the OFF position.

INSTALLATION

RF Address Code Setting

• If there is another user nearby, e.g. in the next house, your receiver may be faulty triggered by their transmitter.
• You may select a different RF address code to prevent this. Receiver can only response to RF coding with the same address code setting as its own address code.
• To adjust address code of Power control unit, simply left or right of the 5 dip switch levers.
• To adjust address code of Control Centre, open the housing of the transmitter unit. See removing of back housing of Control Centre section on how to open the housing.

Caution:

•  Address code of Control Centre must be the same as address code of Receiver.
• For any ON position of address code # in Control Centre, the same address code # of Receiver must be switched to ON.
•  Disconnect AC power and remove batteries prior to adjusting address code.

Removing your old thermostat

Read the following instructions carefully before disconnecting the wires.

• Turn off your old thermostat.
• Remove the cover from the old thermostat.
• Unscrew the old thermostat from the wall plate.
• Now find the screws attaching the wall plate to the wall, and remove them.
• You should now be able to pull the wall plate a small distance from the wall. Do not disconnect any wire yet, simply locate the wires.

WARNING: After removing the wall plate, if you find that it is mounted on a junction box (e.g. a box similar to one behind a light switch or electric outlet), high voltage circuit may be present and there is a danger of electric shock. Please consult a qualified electrician.

Choosing a Location
Note: for a new installation, choose a mounting location about five feet (1.5 meters) above the floor in the area with good air circulation and away from:

• Drafts.
• Air ducts.
• Radiant heat from the sun or appliances.
• Concealed pipes and chimneys.

Mounting the Receiver onto the wall

• Remove the back plate from the Receiver.
• Mark the holes position.
• Drill two holes and insert the plastic anchors carefully into the holes, fasten the back plate to the wall with 2 screws.
• Connect the wires – see wiring diagram.
• Push on the wires in the wall.
• Securely fasten the Receiver to the back plate.

Wiring diagram

RECEIVER WIRING TERMINALS

• NO switch terminal – Normally opened
• COM switch terminal
• L Live feed 230V AC
• N Neutral

Mounting the Control Centre onto the wall (if you don’t need to use its mobility)

• Remove the back housing of the Control Centre.
• Mark the holes position.
• Drill two holes and insert the plastic anchors carefully into the holes, fasten the back housing to the wall with 2 screws.
• Securely fasten the Control Centre to the back housing.

SETTING OF CONTROL CENTRE

Heater/Cooler Selection
Before making any selection in the Control Centre, its back housing must be removed. Inside the Control Centre after the back housing is removed, you can find 3 DIP switches. These three switches are used to control the span and heat/cool system. Set the DIP switch (position 3) according to your selection of heater system or cooler system according to the following diagram. Switch no. 3

Temperature Span Selection
Span is the temperature difference between the turn on temperature and turn off temperature. For example, in heating systems, if you set temperature to 20°C and span to 0.8°C, the heater will operate when the room temperature drops to 19.2°C and turns off when the temperature rises to 20.8°C. Set the DIP switch (position 1 & 2) according to your selection of temperature span as the following diagram.

Battery Installation

• Your thermostat uses two “AA” size batteries to operate.
• To power-up the unit, insert two “AA” batteries into the battery compartment of the front housing. When power is applied for the first time, the display must show time and the day as well as the room temperature.
• If the display is different, press the RESET button. Use a fine probe such as straightened paper clip to gently push the RESET button.
• After installation of the batteries, push back the rear housing to the Control Centre and then the stand. Before turning on the main switch of the system, press the reset button once. The thermostat is ready for use.

Testing the RF Transmission Range

• Press UP button until the set-point temperature is higher than room temperature by a few degrees.
• Wait for a few seconds.
• Check the green LED on the Receiver. It should be ON.
• If the LED is not ON, try to place the Control Centre closer to the Receiver. Press the Down button to adjust the set-point temperature to be lower than room temperature to “turn off” the receiver.
• Repeat steps 1 to 4.
• The receiving range between Control Centre and Receiver is 70M in open area. When placed indoors, this distance may be shorter because of blocking by concrete walls etc, but is enough for most household applications.
• Press RESET button after testing of receiving range.
