Verify type of application
Digital remote control with integral room temperature sensor and an OpenTherm interface for connecting a boiler control.
The remote control allows various operating functions, including
heating based on heating program, setting of individual room and
hot water temperature and monitoring of boiler data in the living area.
The LAGO FB OT uses the weather or room-based control function
to transmit the desired boiler value to the boiler controller via the
weather and/or room guided control function to make sure that the
gas boiler delivers the required heat volume at optimum efficiency.
When used with boiler controllers that support the OpenTherm Smart Power function, the display of the Lago
FB OT remote control is illuminated during operation.
The function is only guaranteed within the specified limits, see page
22 (Technical data).
Any other use will be deemed improper use.

User – Set parameters
Explanation of the parameters
P01 Heat slope
Selecting the correct heat slope saves energy because the heat
sources only heat to the point required by the respective outside
temperature.
The heat slope specifies the number of °C by which the flow temperature changes when the outside temperature rises or drops.
▷ Before you select the heat slope, set the room temperature to
the desired value, see page 6 (Set the desired temperature).
▷
Ideally, the heat slope is set when the outside temperature is
below 5 °C. Changes to the heat slope setting must be applied
in small steps and long intervals (at least 5 – 6 hours between
steps). The system must be allowed to adjust to the new value
after each change to the heat slope.
▷
Select the heat slope so that the desired room temperature is
achieved with the thermostat valves fully opened, and doors
and windows closed.
▷ Increase the heat slope if the desired room temperature is not
reached in combination with low outside temperatures.
▷ If the desired room temperature is not reached in combination
with high outside temperatures, increase the desired room temperature.
• Now change the heat slope.

P02 Room sensor influence
It is possible to adjust the influence of the room sensor on the control
process.
▷
The higher the set value the greater the influence of the room
sensor on the calculated flow temperature.
P02 = OFF purely weather-guided control
P02 = 0: purely weather-guided control
P02 = 20 purely room temperature control
Within the range 0–20 the heatcircuit pump operates up to the next
heating time if there is a heating requirement during the period of
reduced temperature Night (e.g. frost protection of when the temperature drops below the setback temperature). This prevents the
rooms from becoming too cool.
14
User – Questions
Example: P02 = 5
With this setting the desired temperature of the heat source is increased by 5°C when the room temperature drops below the desired
room temperature by 1°C.
P0 Room sensor correction
This setting can be used to correct measurement errors of the connected room sensor, e.g. when the room sensor is influenced by
incorrect positioning.
Setting range: P03 = -5 to +5 °C:
Example: Room sensor correction
Your room sensor measures 20 °C. A reference thermometer, however, determines 22 °C. Now set parameter 11 = 2 so that the value
2 °C is added to the measured value.
P04 Hot water according to program
This parameter can be used to define the heating times for hot water.
P04 = 0: Off (no hot water preparation)
P04 = 1: hot water in line with heating program 1
P04 = 2: hot water in line with heating program 2
P04 = 3: 1 hour before the heating times of automatic mode 1 or
2. (The desired automatic mode is set via the operating mode.)
With activated HO Holiday mode the hot water preparation is not
switched on.)
In “Summer” mode parameter 04 must be set to 1, 2 or 4.
P04 = 4: 24 hours hot water
User – Questions
How do I switch to summer/winter time?
To switch from summer to winter time and vice verse you need to
reset the time, see “page 6 (Set time and day of the week).
How do I set the heating controller so that it gets warm sooner in the morning?
There are two heating programs to set the heating times.
Heating program 1 for setting the heating times Mon–Fri (working
week) and Sat–Sun (weekend) for the week as a whole,
Heating program 2 for setting the heating times for each day of the
week Mon, Tue, Wed, Thu, Fri, Sat and Sun.
Heating program 1 is assigned to operating mode 1 automatic
mode 1.
Heating program 2 is assigned to operating mode 2 automatic
mode 2.
First select automatic mode 1 or 2, see page 7 (Set operating mode).
Then adjust the associated heating program to suit your needs,
see page 8 (Set heating program 1) or page 9 (Set heating
program 2).
Example: P04 = :
If “Automatic mode 1” was selected as the operating mode, the
heating controller will always switch on the hot water one hour before
switching on the heating. If HO Holiday mode is activated, the hot
water is not switched on.

User – Questions
My heating does not get warm enough. What can I do?
You have two options.
First increase the desired room temperature Day, see page 6
(Set the desired temperature).
Wait for a few hours to give the heating system time to respond to
the new setting.
Should the room(s) still not get warm enough, you can increase the
heat slope for the direct heatcircuit or the mixing valve circuit, see
page 14 (P01 Heat slope).
Should this measure not be sufficient, see page 21 (Troubleshooting) and contact your heating engineer.
How do I set the heating system for holidays?
If you want to go away for a number of days, you can set the heating
controller to the operating mode “ Holiday setting”. The heating
system will revert to automatic mode at the end of the holiday so
that it will be warm when you come home, see page 7 (Set
operating mode).
How can I switch the heating system off during the summer?
In summer you should set the heating controller to the operating mode
“Summer mode”. This mode deactivates heating and the system is
only used for hot water, see page 7 (Set operating mode).
Is it possible to let the heating system run longer in the evening for special occasions such as a party?
For this purpose, set the operating mode to /Eco, see page 11
(Heating time setting/Change duration).
How do I set the heating controller to save energy?
Set the desired room temperature only as high as absolutely necessary. The energy consumption is increased by around 6% for every
degree, see page 6 (Set the desired temperature).
Set your heating program so that it switches the heating off at night
or at times when no-one is home.
Only open you windows briefly to let in fresh air. Avoid tilted windows
over longer periods.
My heating system is not running
Check the selector switch position. The selector switch must be
set to .
Check the operating mode. The display must indicate for Automatic mode 1, or 2 for Automatic mode 2, see page 7 (Set
operating mode).

Troubleshooting
? Fault
! Cause
• Remedy
When a fault occurs, the error number is indicated in the display
(Example: E 81).
You can find the error numbers in the heat source instructions.
? The display shows an error no. between E001 and E255.
! Boiler error. If there is an arrow in the display pointing to “Reset”,
the error can be deleted using the remote control.
• Turning the rotary knob sends a reset telegram to the OT boiler.
The boiler is automatically restarted.
! If there is another arrow pointing to Water pressure too low,
the water pressure can be raised using the remote control.
• Turning the rotary knob tops up the water in the boiler. (Condition: The boiler supports the “Water Filling Procedure”, see heat
source instructions.)
? The display shows error no. E 81.
! EEPROM error. An invalid parameter has been replaced by the
default value.
• Check parameter values.
• Switch mains power off and on again to reset the error no.

Technical data
? When displaying the actual values on the remote control, you
realise that the indicated value does not match the real one. For
example, the actual hot water temperature is 20 °C, but the
display shows 65 °C (or vice versa).
! An incorrect sensor is connected.
• Only use sensors with identical characteristic curves.
? The hot water stays cold during summer mode.
! Parameter 04 = 03 set (hot water 1h before heating)
• Set P04 = 01 or 02.
Should the actions described above fail to help, please
contact your heating engineer.
▷ Please have ready the software version (parameter P13).

Glossary
Flow temperature
The flow temperature is the temperature to which the heat source
heats the water that transfers the heat to the consumer (e.g. radiator).
Desired and actual temperature
The desired temperature (or setpoint temperature) describes the
desired temperature for a room or for hot water.
The actual temperature denotes the actual temperature that prevails.
The heating controller has the task to adjust the actual temperature
to the desired temperature.
Setback temperature
The setback temperature is the desired temperature to which the
heating system heats outside heating times (e.g. at night). It should
be set so that the rooms do not cool down too much while saving
energy.
Heat source
Heat source is generally the designation for the heating boiler. It may
also be a buffer storage tank however.
Heating time
In the heating programs you can define up to three heating times per
day, one for the morning, one for lunchtime, and one for the evening
for example. During a heating time, the temperature is controlled to the
desired room temperature. Between heating times the temperature
is controlled to the setback temperature.
