ELEKTROBOCK BT22 Manuale utente

MADE IN CZECH REPUBLIC

BT22 is an ideal solution for places where it is expensive or completely impossible to pull wires from

thermostat to the boiler. It is designed for automatic regulation of heating systems in family houses and

housing units with own boiler (gas, electric). Large backlit display on allows the transmitter to control the

thermostat even in the dark. In addition, it oers intuitive navigation in the selected language (CZ / PL /

EN / DE / RU / SK). The receiver is equipped with a code self-learning system and E-EPROM memory, which

stores the save code even in the event of a power failure. BT22 works with two-way communication on the

frequency 433.92 MHz. The range of the set can be up to 35 m (built-in).

RECEIVER CONTROLS

RECEIVER ASSEMBLY

LEARNING CODE

• switch o the main circuit breaker

• connect the receiver to the boiler according to the diagram (for the boiler use the termi-

nals designed for room thermostat 2 wires!)

• connect the receiver to the 230V / 50Hz mains

• switch on the main circuit breaker, the green LED on the receiver lights up and the recei-

ver is ready to the next setting

Install the receiver (indoors) as far away as possible from large metal objects

(min. 0.5 m) and outside power lines due to signal reception! We recommend that the

installation is carried out by a person with the appropriate electrical qualication!

The BT22 assembly is factory congured and ready for use - after commissioning the receiver

and transmitter, simply use the TEST function (see page 6)! However, if the receiver‘s memory is

cleared - the red LED ashes, use the following procedure:

1. Press the“FUNCTION BUTTON” on the receiver for approx. 1.5 s, the yellow and red LED, the

receiver is waiting for a code (so-called learning mode).

2. On the transmitter (after inserting the batteries, see page 3), press the“MENU” button twice,

turn the button “ “ choose CONST mode and pressing the button several times.“ “ go to TEST.

Turn the button “ “, the signal is sent to the receiver. The for sign appears briey on the transmitter

wireless broadcasting“ “ and when communication is established, RFM lights up permanently.

3. Acceptance of the code into the receiver is indicated by the simultaneous ashing of the yellow and

red LEDs, that is code learned. After receiving the code, the output relay will be closed several times

for verication correct function BT22.

Indication LEDs:

YELLOW FLASHES - transmitting or receiving a signal

RED FLASHES - empty E-EPROM memory

BATTERY REPLACEMENT

When appears on the display“ “ the batteries must be replaced.

1. Remove the control unit from the bottom cover of the

appliance (g.1).

2. Replace the batteries. Make sure the polarity is correct

marked in the battery compartment (Fig.2). After removing

the batteries of the thermostat retains all settings in memory.

Always use alkaline 2 x 1.5 V AA batteries!

Check the time setting after replacing the batteries!

Recommendation: replace the batteries before each heating season!

Dispose of used batteries in accordance with hazardous waste regulations!

TRANSMITTER DESCRIPTION

TRANSMITTER INSTALLATION

The transmitter must be located as far away as possible from sources of interference (TV, PC, etc.) and

must not be located on a metal base. When placing it, pay attention to the thermal properties of the

place.

• open the rear cover of the transmitter according to Fig.1

• we will remove the protective paper from the batteries and the transmitter will be fully functional

(BT22 are batteries) a part of the package)

• snap the back cover back - the transmitter is freely portable and can be placed, for example, on a

table. We recommend using table stand, which is part of the package (assembly see Fig.3)

• when installing on the wall, make sure that no high-current lines pass around the thermostat!

It is used to correct the temperature measured by the

thermostat. The setting must be made only after 12 hours

of operation, when the temperature of the internal sensor

stabilizes. Measure the room temperature with a thermometer,

if the temperature diers from the temperature on the

thermostat, set the correction from -5 ° C to + 5 ° C.
