Digital remote control with integral room temperature sen-
sor 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 Open-
Therm 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 tem-
perature 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 tem-
perature.
• Now change the heat slope.
▷Typical values:
Floor heating: 0.4 to 0.8
Radiators: 1.0 to 1.5

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 tem-
perature drops below the setback temperature). This prevents the
rooms from becoming too cool.

User – Questions
Example: P02 = 5
With this setting the desired temperature of the heat source is in-
creased 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 conn-
ected 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, how-
ever, 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
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
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 operat-
ing 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).

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 (Troubleshoot-
ing) 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 neces-
sary. 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 Auto-
matic mode 1, or 2 for Automatic mode 2, see page 7 (Set
operating mode).

Possible life-endangering electrical shock! Switch the power off to
electrical cables before working on power-carrying parts!
CAUTION
For fixed devices, an isolating mechanism must be installed for
shutting off from the network, in accordance with the installation
guidelines and EN 60335, e.g. with a switch.
The insulation for line conductors is to protected against damage
by overheating, e.g. insulating sleeve.

Phone switch
A telephone switch can be used to switch the heating into heating
mode. If a short circuit is detected between terminal 3 and 4, the
heatcircuit assigned switches into heating mode. Hot water prepara-
tion is also activated. Once the short circuit is removed, the heating
automatically reverts to the previous operating mode.

Explanation of the parameters
P05 Code no. input
Here the code no. defined via P06 is entered for adjustment of the
Expert parameters.
▷The default setting for the heating controller is 0000.
P06 Code no. change
Here you can specify your own code no. Remember this code well!
The parameters 06–13 can not be changed without this code no.
Should you forget the code no., the factory settings must be re-
loaded, and this means that all your settings will be lost, see page
12 (Load factory settings (Reset)).
• Change every digit of the four-digit code no. and confirm by
pressing the OK button.
P07 Maximum boiler temperature
P07 = 20.0–110.0 °C: The heating controller limits the calculated
desired temperature of the heatcircuit to P07 to protect the consumer
from overheating, e.g. when an underfloor heating system is installed.
The max. value can be restricted by the heat source.
P08 Minimum boiler temperature
P08 = 10.0–110.0 °C: The heating controller increases the calculated
desired temperature of the heatcircuit to P08, e.g. when air heating
is installed. The min. value can be restricted by the heat source.

P09 Outside temperature frost protection
P09 = ----: Frost protection is deactivated.
P09 = -15.0 to +5.0 °C: When the outside temperature drops be-
low the set value, the heatcircuit controller switches the heatcircuit
pumps on.
P10 Integral control section
Integral component for the flow temperature. Enter a time here. If the
room does not reach the required temperature in the time set (from
the start of heating), the flow temperature is gradually increased until
it is sufficient to reach the desired room temperature.
P10 = ----: Function deactivated.
P10 = 3:00 h – 0:15 min: Time to reach desired room temperature
after start of heating time.
P11 Transparent Slave Parameter 01
Setting for internal parameter 01 for heat source.
P11 = -255–255: The values are only accepted by the heat source
if they are within this range.
P12 Transparent Slave Parameter 02
Setting for internal parameter 02 for heat source.
P12 = -255–255: The values are only accepted by the heat source
if they are within this range.
P1 Software version and index (62.00)
P13 = 62.00–62.99:
62 = software number
00–99 = software index
▷If you have questions about your remote control, always specify
the software version.
