Device: HmIP-FAL24-C6 - Homematic IP Floor Heating Actuator 6 channels, 24 V
Company: eQ-3, Maiburger Str. 29, 26789 Leer, Germany
Version 2.6.0 - 2026-03-20
Application: 2.6.0
Bootloader: 1.14.0
BootloaderWired: 1.6.0
Library: 1.94.0
** Improvement
- Evaluation of heating/cooling in the Heating Controller Mode frame to ensure
consistency in the system.
If the device detects an inconsistency between heating/cooling with the wall
thermostat, the mode in the wall thermostat is overwritten by the device.
- Heat demand stays OFF after reboot of the IO box
To allow the heat demand control to resynchronize after a reboot of the MIOB or
WHS2, a Conditional Switch Command with a value of 200 is sent at the start of
the PWM cycle time (default 15 minutes).
Version 2.4.006 - 2023-08-04
Application: 2.4.006
Bootloader: 1.14.000
BootloaderWired: 1.6.000
Library: 1.64.000
** Bugfix
- In stand-alone mode, the heat pump was not switched off 15 minutes before the last
valves were closed.
- Change from summer to winter time was not working.
- Activation of pump function via select button in FW 2.2.6 not possible
- After a communication error with the wall thermostat has been resolved, the
channel LED may display an incorrect status for up to 15 minutes.
** New Feature
- Added new parameter DEVICE_OPERATION_MODE to enable calculation of improved on times
and post processing planner (for operation with heat pumps).
- Added new parameter HEATING_PWM_CYLCE_TIME.
Version 2.2.006 - 2022-05-30
Application: 2.2.006
Bootloader: 1.14.000
BootloaderWired: 1.6.000
Library: 1.64.000
** Bugfix
- DEC Identify: Time for display illumination was wrong.
The lighting duration of the backlight and the system button by sending the DEC
"Identify" does not correspond to the specification.
- The channel 10 cannot be controlled above 17°C in pairing mode.
After pairing, the device transmits the information to the wall thermostat
whether External Clock is active or inactive. In this case, it is erroneously
transmitted actively, so that the setting of the target temperature on the wall
thermostat is limited.
- Dew point sensor alarm from the MIOB was not forwarded to the MIOB switching
output (dehumidification control).
If dew point alarm was reported by the MIOB, this information was only forwarded to
the wall thermostats but not back to the MIOB to the switching output (dehumidifier
control).
- WTH-2 "%" symbol is not removed when the humidity and dew alarm are cancelled.
- In the case of NormallyOpen, the LED states are not displayed correctly when the
channels are switched on manually on the device.
** Improvement
- The time information telegram does not contain a note about the summer / winter
time change.
So it was possible that a time request to the access point in the period where the
changeover from summer to winter time takes place could lead to a double
changeover.
- Perform valve protection function on all channels
The valve protection function was previously only executed for channels that were
also linked to a wall thermostat. This has changed, the function is now also
executed for channels that do not have a link partner. However, the channels with
a link partner are decisive for the execution.
** New Feature
- Extension of the humidity limit by a pre-limit.
Humidity Monitoring has been extended by a threshold. With the help of this
threshold, a first alarm can be triggered even before the current threshold. The
first alarm activates a dehumidifier in connection with a MIOB, when the second
threshold is triggered, cooling is also stopped, and the corresponding valve is
closed.
Version 2.0.004 - 2019-04-01
** Bugfix
- Correktion of an error when changing from winter to summer time.
On the day of the time change, the time is increased by one hour every full hour
after 2 o'clock.
- Correction of the valve protection function.
The "On_TIME" parameter, i.e. the values for the "Valve protection function
duration" were loaded incorrectly, which meant that the function was not executed
at all.
- Correction of parameter change of lead up time and lead follow time.
Parameter change of lead up time and lead follow time for boiler and for pumpe
control are only adopted after device restart.
- Correction in status info frame by valve type normally open.
Status info bit for valve is inverted if the valve type is changed to normally
open.
- It was possible to link two partners to channel "Output MIOB Boiler" but only one
should be possible.
- Wrong RSSI-Level in status info package
RSSI level in cyclic status info must always be 0x80.
** Improvement
- Adjustment to switch off the local pump.
Depending on the system, the pump is switched off after each PWM cycle. However,
this only makes sense if the switch-off is carried out for a longer period of
time. This is now guaranteed, if a short switch-off time is determined, the
switch-off is not carried out.
** New Feature
- Channel extension for change-over function.
Through the channel extension, it should be possible to switch between heating and
cooling via the MIOB without the pump or boiler channel being connected.
Version 1.8.006 - 2018-03-16
** Bugfix
- Expansion for inclusion condition.
If parameter changes have been made to the device before the inclusion, the device
can only be included if a factory reset has been performed on the device before.
- Expansion for inclusion condition.
Activation of the pump function on heating zone 1 directly at the FAL is blocked
after inclusion.
- Function modification during two-point control.
During the two-point control (startup sequence), the device do observe the
parameter values "COOLING_DISABLE" and "HEATING_DISABLE".
- Correction in Paging-Module HMOS-Library.
Catched erros which could occure after an OTAU update to a newer
paging module.
- Correction for determining the heating or cooling mode after a power failure
In order to execute the right set heating or cooling mode after a power failure,
the time request in inclusion mode is not limited to the request at the access
point, if this is not available, a time request is send to a link partner
requests and therefore indirect also the correct operating mode.
- Correction when switching between load balancing and load collection during
operation.
If load balancing and collection were changed during operation, the load
collection was not carried out correctly.
- Correction for switching off the local pump relay.
If the local pump function is deactivated, the pump relay is deactivated.
- Correction for determining the heating or cooling mode after a power failure in
connection with a MIOB.
After a power failure, the DEC of the MIOB must be evaluated separately so that
the linked wall thermostats are not inadvertently switched from cooling to
heating.
** New Feature
- Parameter extension for installer solution.
With the help of the new parameter "DISABLE_MSG_TO_AC" all transmissions to the
central address are suppressed. Also to the status receiver address if this is the
same as the central address.
** Modification
- Extension for pairing with a FALMOT
Version 1.6.002 - 2017-01-31
** Bugfix
- Improvement of data communication.
During data communication with a partner, it is possible to receive data from a
second partner.
** Modification
- Pumps and boiler channel are separated for inclusion mode into two channel in order
to separate the pumps and boiler control. This solution allows the separate
adjustment of pumps and boiler delay times.
** Improvement
- In the case of a configuration change of the valve type, the channel output control
is updated immediately.
Version 1.4.002 - 2016-10-20
** Bugfix
- First long system button press for Factory Reset was 500 ms too short.
- Global pump protection function (in conjunction with the MIOB) is working now.
- Diagnostic channel test function can always be deactivated as desired.
- The "Humidity Limiter" flag in the Status-Message is set, if humidity limit is
reached.
- In "Inclusion Mode" date and time are still requested, even if it is not needed.
The reason is the "Date Time Unknown" flag in the Status-Message, this could
irritate the customer.
Version 1.2.001 - 2016-08-23
** Bugfix
- The parameter "ONDELAY_TIME" and "OFFDELAY_TIME" of the pump are set properly.
- If humidity limit has been exceeded and the function is disabled, this is
communicated to the Wall Thermostat.
- Heating Clock Funktion is operate as specified.
Version 1.2.000 - 2016-08-10
First Release.
