Room Thermostat

GENERAL DESCRIPTION OF THE THERMOSTAT

This type switched-mode room thermostat is suitable to regulate

the overwhelming majority of boilers available in Europe. It can

easily be connected to any gas boiler or air conditioning device

that has a double wire connector for a room thermostat, regardless

of whether it has a 24 V or 230 V control circuit.

Temperature can be measured more precisely as compared

to simple, conventional thermostats. In accordance with the

selected switching sensitivity, the thermostat will switch the boiler

or any other appliances on and off below and above the adjusted

temperature, respectively, and contributes to reduce energy costs

while maintaining comfort.

-2-

The switching sensitivity of the thermostat is ± 0.1°C (± 0.2°C). This

means the difference between the adjusted temperature and the

actual temperature

measured during the

switching process.

For example, if

the factory default

setting is 20°C on

the thermostat, then

the device switches

the boiler on at

19.8°C or below,

and switches it off at

20.2°C or above.

The information shown on the liquid

crystal display of the thermostat

1. LOCATION OF THE DEVICE

It is reasonable to locate it in a room used regularly or for many

hours per day so that it is in the direction of natural ventilation in the

room but protected from drought or extreme heat (e.g. direct

sunlight, refrigerator, chimney, etc). Its optimal location is 1.5 m

above oor level.

IMPORTANT WARNING!

If the radiator valves in your at are equipped with a thermostatic

head, replace the thermostatic head of the radiator valve with

manual control knob or adjust it to maximum temperature in the

room where the room thermostat is to be located, otherwise the

thermostatic head may disturb the temperature control of the at.

2. INSTALLATION OF THE THERMOSTAT

• To install the thermostat, Remove the

rear panel of the thermostat from the

front panel using a screwdriver as

shown.

• With the help of the screws provided and

some tools fasten the rear panel of the

device to the wall.

• Using a small screwdriver, remove the

cover of the terminal block from the inner

side of the rear panel.

Attention! The device must be installed

and connected by a qualied professional.

Always follow the manufacturer’s

instructions when connecting the

thermostat to any heating or cooling

appliance. The voltage appearing at

terminal No. 1, No. 2 or No. 3 depends

only on the system being controlled,

therefore the dimensions of the wire

are determined by the type of the

device to be controlled. The length

of the wire is of no signicance.

3. PUTTING THE THERMOSTAT INTO OPERATION

-7-

To put the thermostat into operation, Remove the rear panel of the

thermostat from the front panel as shown

The battery compartment is on the inside of the front panel of the

case. Insert 2 AA alkaline batteries (TYPE LR6) into the battery

compartment as shown. After inserting the battery, the display

ashes to measure the room temperature

4. Coding switch selection

After removing the rear panel of

the device, desired Settings can

be obtained by changing the

coded switch on the PCB

board.

5. SETTING THE DESIRED TEMPERATURE

-9-

When the factory default temperature is set to 20°C and the factory

default temperature is set to 20°C, the temperature of the

thermostat switch on the connected heating device is lower than

19.8°C (connecting terminals 1 and 2) and higher than 20.2°C

(disconnected terminals 1 and 2) under the switch sensitivity

(±0.2°C).

Adjust the knob, the display screen at the upper left corner will

appear "SET" (adjust the temperature) prompt, the back is bright,

(SET the temperature on the display gray), adjust the knob can be

adjusted to 5-35℃.

• Approximately 5 seconds after setting the room temperature to

be maintained, the device automatically switches to normal mode.

The notice “ SET ” disappears from the bottom right corner of the

display, and once again the current room temperature is displayed.

6. Heating Mode

According to the change in room temperature and temperature

setting, the device controls (switches on or off) the boiler or any

other heating equipment connected to the appliance. When

activated, the normally open contact pairs, i.e. No. 1 (NO) and No.

2 (COM), of the relay of the device clamp shut, and, as a

consequence, the appliance connected to the thermostat is

switched on. The appearance of the notice “HEAT” in the bottom

left corner of the display indicates that the device is activated.
