4.3 Thermostat registration
To get the FH-BU base into registration mode
Press and hold “MODE” and “OK” buttons on base unit for 3 seconds, (all LED’s
will flash) then release “MODE” and finally release “OK”. The system is now in
registration mode. Only the “POWER” LED should be on (unless thermostats
already have been assigned earlier- then the LED for these will be on)

Thermostat registration process
Using the point of a pencil press and release the thermostat transmission
button. The LED for the first available channel (1-8) will start to flash.
Select the channel to be assigned to the thermostat by pressing the “MODE”
button numerous times until the LED for the desired channel flashes. Then
press and hold “OK” for 3 seconds (the LED will flash and finally be on). The
thermostat is now registered. Repeat the thermostat registration process
for each thermostat. (Also if one thermostat should be assigned to several
channels).
After registering all thermostats, press and hold “MODE” for 3 seconds (all
LED’s will flash), to return the system to normal mode.
Note:
The system returns automatically to normal mode if no buttons are
pressed during a 5-minute period.
4.4 De-registering thermostats
To get the FH-BU base unit into de-registration mode
Press and hold “MODE” and “OK” buttons for 3 seconds, (all LED’s will flash)
then release “OK”, and finally release “MODE”. The system is now in de-
registration mode. (If only one thermostat is assigned the first assigned LED
will start to flash).
Press the thermostat transmission button. The LED for the first assigned
channel will start to flash, (the rest will be on). Select the channel to be de-
registered by pressing the “MODE” button numerous times until the LED for
the desired channel flashes. Then press and hold “OK” for 3 seconds, (the LED
will flash and finally go out). The channel is now de-registered. Repeat the
thermostat de-registration process for each channel to be de-registered.
After de-registering thermostats, press and hold the “MODE” button for 3
seconds (all LED’s flash) to return the system to normal mode.

Note:
The system returns automatically to normal mode if no buttons are
pressed during a 5-minute period.
4.5 Setting room temperature
The temperature is set by turning the thermostat setting knob to the desired
temperature.
4.6 Setting min./max. temperature
Lift thermostat cover.
Set min./max. temperatures using the red and blue limiters respectively.
4.7 Setting thermostat operating mode
Switch position “sun” => normal => no night set-back.
Switch position “moon” => night set-back => 4°C at 20°C.
Switch position “clock” => timer-controlled set-back.
If timer-controlled set-back is required, it must be programmed via the time
clock/timer module (optional) fitted to the base unit.
5.0 Special functions
5.1 Master reset
This function deletes all registered data and reinstalls factory settings.
Switch off the power supply, press and hold “OK” and “MODE” simultaneously
and keep pressing them while switching the power back on.
LED indicators 1-8 then light up consecutively, and finally all eight indicators
flash. Release “OK” and “MODE”.
The system has now been reset to initial factory settings.
5.2 Transmission testing
Transmission testing is used to test and identify all registered thermostats.
Press and hold “OK” for 3 seconds (all LED indicators flash).
All channels with assigned thermostats light up on the indicator panel. When
a channel receives a signal from a thermostat, the corresponding indicator
flashes twice and the indicators go off. If a signal is subsequently received
from the same thermostat, the indicator for the corresponding channel
flashes twice.
The test is automatically terminated once all channels have received a signal
from their assigned thermostat.
