Device: HmIPW-WTH - Homematic IP Wired Wall Thermostat with Humidity Sensor
Company: eQ-3, Maiburger Str. 29, 26789 Leer, Germany
Version 3.0.2 - 2024-04-08
** Bugfix
- Symbol display for heating / cooling is missing if an actuator link exists.
With the new FW version it is now possible to operate the two-point control
depending on the operating mode (heating / cooling). Here, the symbol should also
be shown on the display accordingly.
- The Encoder-Button response without backlight "Off", only worked every second time.
- The "Heating Controller Mode" frame was sent several times.
The "Heating Controller Mode" telegram was sent cyclically to each channel of the
FAL. It is sufficient if the telegram is sent to the FAL only once.
- Boosttime was set in Party-Status-Info-Frame even if boost was not active.
- Boot flag is reset prematurely.
If a time info request is sent after a restart, the boot flag must not be missing
in the regular status frame. If no response is sent from the access point to the
time info request after a restart, the boot flag must not be reset in the status
until the status frame has been acknowledged.
- The device send no DEC telegram to link partners if a new link partner was
previously added or removed.
- Instead of a conditional switch command the device should send a level command to
linked switch actuators. This allows the actuator to be deactivated directly by
the wall thermostat
- Emergency shutdown at 30°C during cooling.
Cooling is also active when the set temperature is greater than 30.0°C
- Hysteresis for 2-point control with switching actuator does not work as specified.
The hysteresis was not evaluated correctly for the humidity. The resolution
should be 1%. However, it actually had a resolution of 2%.
** Improvement
- The automatic switchover from manu-mode to auto-mode after a restart following
receipt of the first time-info telegram should be deactivated.
- The "Heating Controller Mode" frame was sent several times.
The "Heating Controller Mode" telegram was sent cyclically to each channel of the
FAL. It is sufficient if the telegram is sent to the FAL only once.
- Instead of a conditional switch command the device should send a level command to
linked switch actuators. This allows the actuator to be deactivated directly by the
wall thermostat.
- The cooling profile factory setting is set to 28°C.
** New Feature
* Implementation of the "Heating controller 2 bit field" parameter in list 1 for
channel 5
The parameter values COOLING_ENABLE and HEATING_ENABLE were added for channel 5
(Actuator link partner). This makes it possible to deactivate cooling or heating
in the respective mode.
Version 2.8.010 - 2022-10-10
** Bugfix
- After reinclusion, partly cyclic data telegrams for eTRV, actuator and FAL are not
sent.
Version 2.8.002 - 2021-12-08
** Bugfix
- Device does not respond to ALL_TRIPLE_BURST_LISTENING_DEVICES.
A generally valid message to the address ALL_TRIPLE_BURST_LISTENING_DEVICES is
supported now.
- DRIx window contacts of a room cannot form the necessary AND connection.
If a window contact with several channels is linked as partner, window-closed was
already detected if only one channel of the window contact reported window-closed.
** New Feature
- Switchover for use either as thermostat or as hygrometer (2-point control) with
effect on the actor channel and/or internal switching actuator.
Via the parameter setting it is now possible to switch the actuator channel 5
depending on the humidity.
** Improvement
- Whenever connection to link partner FAL is checked, the led is blinking.
If the wall thermostat is linked to a FAL or FALMOT, the link connection is
checked every 50 minutes as standard. This results in a flashing LED on the
thermostat. Especially if the connection is made via a router, this flashing could
take longer. This should not be the case as it will cause confusion for customers.
The LED should only be triggered when the customer makes manual changes.
- 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.
- Automatic switching between heating and cooling at the two-point control for
actuator channel 5.
Up to now, the parameter "Art der Zweipunktregelung" was used to specify whether
the two-point control for the actuator channel 5 should heat or cool. This
parameter has now been extended by the value heating and cooling. If this value is
now selected, the two-point control is automatically changed to heating or
cooling.
- Smart RX FAL cyclic packet reduction
To reduce the radio load, a check is made before each cyclic data telegram is sent
to the FAL or FALMOT to determine whether it actually has to be sent. If there has
been no change in the mode, the actual temperature, the humidity and the set
temperature, the packet does not have to be sent every cycle.
Version 2.6.000 - 2019-09-04
** 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.
** New Feature
- Improvement for data communication.
If possible the device send multicasts only to PARTNER_ALL_WIRED_DEVICES instead
of to PARTNER_ALL_DEVICES.
** Improvement
- Immediate evaluation of temperature change for the two-point-control.
Temperature changes triggered by the central unit or a window contact, are
forwarded directly to the switching actuators for the two-point-control.
Version 2.4.008 - 2019-03-07
