Operation - Emos T3 Handbuch

Installation
1. Make sure to read the instruction manual carefully before the first use of the thermostat, as well as the
boiler and air conditioning equipment. Turn off power supply before installing the thermostat!
Installation should be carried out by qualified personnel! During installation, observe the appropriate
standards.
2. Choose a suitable location for the thermostat where air circulates freely, with no devices producing
heat in the vicinity, such as a TV set. The thermostat should not be exposed to direct sunshine. We
recommend mounting the thermostat more than 1.5 m above the floor. Note: Never mount the
thermostat on a conductive surface.
3. Open the cover of the thermostat - loosen the screw at the bottom of the unit and remove the top
cover, as shown in Figure A.
4. There are two mounting holes on the back side. Place the unit on the wall and mark locations of the
holes on the wall. Drill 6mm holes into the wall, insert dowels into holes and using screws mount the
thermostat on the wall. No dowels are necessary if the thermostat is mounted on a wooden surface.
In that case, drill 2.6 mm holes.
5. Connection to electrical power: Thermostat is designed for switching max. 230 V/7 A. Never exceed
this limit, otherwise the thermostat will be damaged (burned). Thermostat has three power terminals:
NIN, LIN and LOUT. Use Figure B to connect lines between the thermostat and the switched heat
generating device (HEAT icon).
IMPORTANT: Ensure power supply is OFF when installing the thermostat.
6. Turn the knob of the switch so that the marking on the dial
replace the front cover and gently screw up (Figure C).
7. Turn ON power supply. If the switching indicator (blue LED) blinks twice, the installation was fine.
Within several seconds, the thermostat automatically switches to the heating control mode with
the LED ON.
Note: If the switching indicator (blue LED) does not blink, turn OFF power supply, check the wiring and turn
the unit ON again.

Operation

1. Turning ON the thermostat temperature control: Set the switch to "HEAT". Thermostat will control
the room temperature.
2. Room temperature is controlled by adjusting the knob to the desired temperature which is on the
dial.
3. Once the thermostat switches the heating system ON, the indicator light goes ON. Thermostat has
built-in protection against rapid cycle change - time delay switch - thermostat does not react to
changing temperature settings immediately.
4. Turning OFF the thermostat temperature control: Set the switch to "OFF". Now the room temperature
control will be disabled (control of the heating system will be permanently off ).
Automatic temperature reduction "SET-BACK"
The function provides temperature reduction of 5 °C for a fixed time interval. For example, if the
temperature of the dial is set to 22 °C, it will be reduced to 17 °C during the SET BACK mode activation.
The time period of the set-back function is 6 hours. For example, if the SET-BACK changes the tempera-
ture at 23 h, then the originally set value is resumed at 5 hours. The cycle of the SET-BACK temperature
change will be repeated until the function is switched off.
Activating the SET-BACK mode
1. Press the button, the SET-BACK function is turned on and the function LED will be orange.
2. Six hours later, the temperature automatically returns to the originally set temperature. The SET-BACK
function LED is green.
3. The following day at the same time, the SET-BACK function will again automatically turn the tem-
perature to the reduced value.
4. To disable the SET-BACK function, press the
is aligned with markings on the wheel,
button again. The function LED goes out.
