EMOS T13RF WIRELESS THERMOSTAT
The T13RF thermostat is intended to control heating or air conditioning systems. Compared to the common home thermostats, the T13RF thermostatic system has separated and wireless connected control unit (transmitter) and the switching unit (receiver). The switching unit is intended to connect and switch the heating/air conditioning systems and the portable unit is used for the temperature manual adjustment. Both units communicate with each other via the radio signal. The system’s advantage is a variability and much easier access to the temperature adjustment.
Important Notice:
Read the instruction manual carefully before first use. Read carefully as well as the instruction manual to the boiler and to the air conditioning systems.
Before you start the installation, disconnect the power supply!
We strongly recommend that only the qualified person should perform the installation! During the installation observe the ordered standards.

INSTALLATION
Control Unit
It is possible to mount the control unit right on the wall or you can place it into the enclosed stand.
Insert 2× 1.5 V AA batteries before the installation.
Use alkaline batteries of the same kind only, do not use the rechargeable batteries.
During the first start-up the display must show the time and room temperature (such as 28.5 °C).
If different sort of data appear on the display, gently push the RESET button. Use a thin straight object to do so, for instance a straightened office paperclip.
Mounting on the wall:
Use the two enclosed screws, mount the back side on the wall. Slide the control unit on the back side.
Installation into the stand:
Slide the control unit into the stand and place in the room.
Thermostat’s Location
The thermostat’s location (the control unit) has a significant influence on its functionality. Select such place, where the family members are the most frequently, the best on the inner wall where the air can freely circulate and the direct sunlight does not reach. The thermostat is not meant to be placed close to the sources of warmth (TV sets, radiators, refrigerators) or close to a door. If you do not observe these rules, the temperature will not be maintained correctly in the room.
Switching Unit
Press carefully the lock on the upper part of the front cover and withdraw the cover:
To attach the contacts, loosen 2 cover-screws and slide the cover upwards.
Attach the contacts as follows
Diagram:
In case the thermostat’s source of the power is the same as well as for the attached device, connect according to the Diagram a). Do not remove the pre-installed wire bridge between the COM contact and L contact!
Connect the phase conductor into the COM terminal.
In case the thermostat’s source of the power is NOT the same, connect according to the Diagram b).
However, before, remove the pre-installed wire bridge between the COM contact and L contact!
Finish the installation of the switching unit by mounting it with the help of 2 enclosed screws. Before screwing the contacts’ cover do not forget to synchronize the control and switching units, see the chapter: Radio Signal Address Setting.
Put the front cover back.
Radio Signal Address Setting
The radio signal address enables the information transfer between the control and switching unit. There may be other different devices operating on the same or similar frequency and they may cause the connection interference or other complications. To avoid such complications it is necessary to use the adequate radio code. For the code setting there are determined 4 switches of a DIP type, placed inside of the both units.
- Before you start to modify the address code, take out the batteries and unplug the main electric cable!
- Withdraw the back cover from the control unit – there are 4 DIP switches on the printed circuit board.
- Set the address code by moving some switches into the ON position and write down their status.
- Set the same code on the switches which are placed in the switching unit. The transmitter’s address code must be the same as the receiver’s address code. DIP switches for the address code setting – marked with the arrow
The Original Thermostat Replacement
ATTENTION: before replacing the thermostat, disconnect the heating / air conditioning system from the main source of
electric voltage in your apartment. Hence you will prevent a possible electric shock. Before disconnecting the electric
cables, read carefully the following instructions:
- Switch off the original thermostat and remove the thermostat’s cover.
- Unscrew the thermostat from the wall plate.
- Unscrew the connecting back plate from the wall. Draw the back plate a small distance away from the wall, however, do not disconnect any wires so far.
- Press carefully the lock of the front cover and withdraw it.
Marking the Wires
- Identify each wire and disconnect it.
- Protect the wires against the possible pull out.
- Avoid any air penetration by using the poly-urethane foam, in case the space behind the thermostat is too large.
Thus you will prevent the incorrect temperature measuring
Testing the Wireless Communication between Units
- By the thumb-wheel set the room temperature about a few degrees higher than is the current room temperature, confirm by pressing OK. Set the AUTO mode on the switching unit.
- Wait a few seconds.
- The upper LED will light up on the switching unit.
- If the LED does not light up, move the control unit closer to the switching unit. By the thumb-wheel set the room temperature lower than is the room temperature – the receiver must shut down and the LED will not be on.
- Repeat the steps 1 to 4. The transmission range between the control unit and switching unit is 60 m in an open area. The range may be shorter indoor due to the signal interference caused by walls and other obstacles.
- After carrying out the test press on the switching unit the RESET button.

Thermostat Setting Tolerance
- Thermostat hysteresis setting (dF)
- Thermostat delay setting (dL)
- Thermostat’s surrounding temperature calibration (TP)
By the thumb-wheel select the SET icon (setting) and press OK.
Thermostat Hysteresis Setting (dF)
Hysteresis is a temperature difference between the intervals, heating ON and heating OFF modes. E. g. when you set the temperature to 20 °C, variance to 0.5 °C, the heater starts working and when the room temperature falls down to 19.5 °C and switches off when the temperature reaches 20,5 °C.
By the thumb-wheel select the (dF) icon and press the thumb-wheel.
By the thumb-wheel set the hysteresis in the range of 0.5 – 2 °C, in 0.5 °C steps,
confirm by pressing OK and hence you will again access the preset mode.
To return to menu press OK again.
Thermostat Delay Setting (dL)
This function will delay the start about 5 minutes.
By the thumb-wheel select the (dL) icon and press the thumb-wheel.
By the thumb-wheel set on/off.
By the thumb-wheel you can switch over between heating/cooling modes or both (we recommend to set the same way for both modes).
Confirm by pressing OK and hence you will again access the preset mode.
To return to menu press OK again.
Thermostat’s Surrounding Temperature Calibration (TP)
The thermometer has been calibrated during its production process, however, to optimize it, it is possible to perform the calibration e. g. according to some reference thermometer.
It is possible to do the thermostat’s temperature calibration in the range of -2.5 (L) to +2.5°C (H).
By the thumb-wheel select the (TP) symbol and press the thumb-wheel.
By the thumb-wheel set the required current surrounding temperature which will be shown in the right part of the display.
Low Batteries
When the batteries are low in the thermostat, the following symbols starts flashing on the display
. Change the batteries.
