GB | Wireless Thermostat with OpenTherm Communication
The P5611OT thermostat is designed for controlling heating and air-conditioning
systems. Unlike conventional home thermostats, the P5611OT thermostatic system
has a separate, wirelessly connected control unit (transmitter) and a switching unit
(receiver). The switching unit is used to connect and switch heating/air-conditioning
systems while the portable control unit is used to control and adjust temperature. The
units communicate with each other via radio signal. The advantage of the system is
its variability and easier access to temperature controls.
Important
• Before rst use, make sure to read carefully the Operating Manual for the thermo-
stat, as well as the manual for the boiler or air-conditioning equipment.
• Turn o power before installing the thermostat!
• Installation should be carried out by a qualied professional!
• Abide by prescribed standards during installation.

LED Indicators
• Blue LED indicates the switching unit is powered by 230 V AC. If the unit is not con-
nected to power or if the main switch is in the OFF position, the blue LED is not lit.

5
• Red LED is lit while the heating/air-conditioning system is active.
Main Switch
If the heating/air-conditioning system is not used for an extended period of time, it is
recommended to turn the switching unit o (move the main switch to the OFF position).
INSTALLATION
Pairing the Control Unit with the Switching Unit
Pairing enables transmission of information between the control unit and the switch-
ing unit.
The units pair automatically (self-learning) after pressing the “ID” button.
1. Insert 2× 1.5 V AA batteries into the control unit (make sure polarity of the batteries
is correct). Use alkaline batteries only, not rechargeable ones.
2. Connect the switching unit correctly to the power source, and press and hold the
“ID” button; the top red LED starts ashing.
Long-press the screen illumination button ( ) on the control unit within 10
seconds.
Both units will automatically pair and the icon will be displayed. The red LED
on the switching unit will stop ashing and goes out.
If the pairing of the units fails, the icon will be ashing instead.
Testing Wireless Communication between the Units
1. Use the button to select a temperature a few degrees higher than the current
room temperature.
2. Wait for approximately 10 seconds or press the button.
3. The red LED on the switching unit will light up.
4. If the LED does not light up, move the control unit closer to the switching unit.
Press the button to set a value which is lower than the room temperature – the
receiver must switch o.
5. Repeat steps 1 to 4.
The maximum range between the control and switching unit is 100 m in an open
space. The range may decrease indoors as the signal has to pass through walls
and other obstacles.
6. Press the “RESET” button once the test is complete.
Deleting the Memory (Code) of Paired Units
To delete the pairing code used between the control and switching unit, follow the
instructions below. Press and hold the “ID” button on the switching unit; the red LED
will start ashing. Short press the “ID” button again within 10 seconds. The red LED
will stop ashing and goes out. The pairing code is deleted.

Replacing the Original Thermostat
ATTENTION: Before replacing the thermostat, disconnect the heating/air-condi-
tioning system from the power in your at. This will prevent potential injury by
electric current. Before disconnecting the leads, read the following instructions
carefully.
1. Turn o the original thermostat and remove the thermostat cover.
2. Unscrew the thermostat from the wall panel.
3. Unscrew the connecting rear panel of the thermostat from the wall. Pull the
rear panel out a sort distance from the wall, but do not disconnect any wires yet.
Marking Wires
1. Identify and disconnect each wire.
2. Secure the wires against getting torn out.
3. If the hole behind the thermostat is too large, seal it with insulating foam to prevent
air ow. This is to prevent incorrect temperature measurement.
Thermostat Placement
Thermostat (control unit) location signicantly aects its function. Place it in a room
where members of the family spend most of their time. Choose a spot preferably on
an inside wall where air circulates freely and there is no direct sunlight. Do not place
the thermostat in the vicinity of heat sources (such as TV sets, radiators, fridges), or
close to a door (due to frequent shocks or vibrations). Failure to comply with these
recommendations will prevent proper control over room temperature.
Mounting the Switching Unit onto the Wall
1. Remove the rear cover of the switching unit.
2. Mark positions for holes.
3. Drill two holes, carefully insert the plastic wall plugs into them and use two screws
to mount the rear cover of the switching unit.
4. Connect the wires to the labelled terminals according to the wiring diagram.
5. Complete the installation by tting the switching unit onto the mounted rear cover.

Mounting the Control Unit (If You Do Not Wish to Use the Unit’s Portability)
1. Remove the control unit’s rear cover.
2. Mark positions of the holes for rear cover.
3. Drill two holes, carefully insert plastic wall plugs and push them in ush with
the wall.
4. Use two screws to mount the rear cover of the control unit.
5. Complete the installation by tting the switching unit onto the mounted rear cover.
Selecting Heating/Air-Conditioning System
1. Remove the rear cover of the control unit – the printed circuit board inside has 3
DIP switches. These 3 switches are used to adjust the temperature dierential
and switch between the heating/air-conditioning system.
2. Adjust the DIP switch (position 3) depending on your choice of heating or air-con-
ditioning system as indicated in the following gure.

Selecting Temperature Dierential
The temperature dierential (hysteresis) is the dierence in temperature required for
switching the system on and o. If, for example, you set the temperature in the heating
system to 20°C and dierential to 0.2°C, the thermostat activates heating as soon
as room temperature drops to 19.8°C and switches heating o when temperature
reaches 20.2°C. Set the DIP switches (positions 1 and 2) depending on your choice of
temperature dierential as indicated in the following gure.

ON ON 0,1°C
OFF ON 0,2°C
ON OFF 0,5°C
OFF OFF 1,0°C

Installing Batteries
The P5611OT thermostat is powered by two 1.5 V AA batteries.
1. Insert two AA batteries into the battery compartment located inside the control
unit. Make sure to observe correct polarity. Use 1.5 V alkaline batteries only; do
not use rechargeable 1.2 V batteries (due to their lower voltage). When you rst
start the unit, the screen must show the time and room temperature.
2. If the screen shows dierent data, gently press the “RESET” button. To do this,
use a thin, straight object, such as an unfolded paper clip.
3. Replace the rear cover once the batteries are in place.
4. Before you turn on the main switch of the switching unit, press the “RESET” button
once. The thermostat is now ready for use.
Attention: After inserting batteries, the transmitter needs up to about 30 minutes to
stabilise parameters!

Setting the Time/Date
1. Press the button to set the day and time. The day indicator (number 1 – Monday
to 7 – Sunday) will start ashing.
2. Use the or button to select the corresponding day number.
3. Press the button and use the or button to set hours. Hold the or
button to speed up the adjustment.
4. Press the button and use the or button to set minutes. Hold the or
button to speed up the adjustment.
5. Conrm the setting using the button.
If no button is pressed for 10 seconds, setting mode ends automatically.
Screen Illumination
Pressing the button activates screen illumination. If no button is pressed for 10
seconds, illumination will turn o.
Setting Temperature
1. Press the CHANGE TEMPERATURE button to switch to temperature setting
mode.
2. Repeatedly press the button to switch between economy mode ( icon)
and comfort mode ( icon).
3. Use the or button to set both temperatures in 0.2°C increments.
4. Save the setting by pressing the CHANGE TEMPERATURE button again.
If no button is pressed for 10 seconds, setting mode ends automatically.
The default comfort temperature is 21°C for the heating system and 23°C for air-con-
ditioning; the default economy temperature is 18°C for the heating system and 26°C
for air-conditioning. Values can be changed, as necessary.
