<h3>MAX</h3>
<ul>
  Devices from the eQ-3 MAX! group.<br>
  When heating thermostats show a temperature of zero degrees, they didn't yet send any data to the cube. You can
  force the device to send data to the cube by physically setting a temperature directly at the device (not through fhem).
  <br><br>
  <a name="MAXdefine"></a>
  <b>Define</b>
  <ul>
    <code>define &lt;name&gt; MAX &lt;type&gt; &lt;addr&gt;</code>

    Define an MAX device of type &lt;type&gt; and rf address &lt;addr&gt.
    The &lt;type&gt; is one of HeatingThermostat, HeatingThermostatPlus, WallMountedThermostat, ShutterContact, PushButton, virtualShutterContact.
    The &lt;addr&gt; is a 6 digit hex number.
    You should never need to specify this by yourself, the <a href="#autocreate">autocreate</a> module will do it for you.<br>
    Exception : virtualShutterContact<br>
    It's advisable to set event-on-change-reading, like
    <code>attr MAX_123456 event-on-change-reading .*</code>
    because the polling mechanism will otherwise create events every 10 seconds.<br>

    Example:
    <ul>
      <code>define switch1 MAX PushButton ffc545</code><br>
    </ul>
  </ul>

        For devices of type HeatingThermostat only. If &lt;temperature&gt; is omitted,
        the current temperature according to the week profile is used. If &lt;temperature&gt; is provided,
        it is used until the next switch point of the week porfile. It maybe one of

        </ul></li>
    <a name=""></a><li>desiredTemperature [manual] &lt;value&gt; [until &lt;date&gt;]<br>
        For devices of type HeatingThermostat only. &lt;value&gt; maybe one of

          <li>"eco" or "comfort" using the eco/comfort temperature set on the device (just as the right-most physical button on the device itself does)</li>
        </ul>
        The optional "until" clause, with &lt;data&gt; in format "dd.mm.yyyy HH:MM" (minutes may only be "30" or "00"!),
        sets the temperature until that date/time. Make sure that the cube/device has a correct system time.
        If the keepAuto attribute is 1 and the device is currently in auto mode, 'desiredTemperature &lt;value&gt;'
        behaves as 'desiredTemperature auto &lt;value&gt;'. If the 'manual' keyword is used, the keepAuto attribute is ignored
        and the device goes into manual mode.</li>
    <a name=""></a><li>desiredTemperature boost<br>
      For devices of type HeatingThermostat only.
      Activates the boost mode, where for boostDuration minutes the valve is opened up boostValveposition percent.</li>
    <a name=""></a><li>groupid &lt;id&gt;<br>
      For devices of type HeatingThermostat only.
      Writes the given group id the device's memory. To sync all devices in one room, set them to the same groupid greater than zero.</li>
    <a name=""></a><li>ecoTemperature &lt;value&gt;<br>
      For devices of type HeatingThermostat only. Writes the given eco temperature to the device's memory. It can be activated by pressing the rightmost physical button on the device.</li>
    <a name=""></a><li>comfortTemperature &lt;value&gt;<br>
      For devices of type HeatingThermostat only. Writes the given comfort temperature to the device's memory. It can be activated by pressing the rightmost physical button on the device.</li>
    <a name=""></a><li>measurementOffset &lt;value&gt;<br>
      For devices of type HeatingThermostat only. Writes the given temperature offset to the device's memory. If the internal temperature sensor is not well calibrated, it may produce a systematic error. Using measurementOffset, this error can be compensated. The reading temperature is equal to the measured temperature at sensor + measurementOffset. Usually, the internally measured temperature is a bit higher than the overall room temperature (due to closeness to the heater), so one uses a small negative offset. Must be between -3.5 and 3.5 degree celsius.</li>
    <a name=""></a><li>minimumTemperature &lt;value&gt;<br>
      For devices of type HeatingThermostat only. Writes the given minimum temperature to the device's memory. It confines the temperature that can be manually set on the device.</li>
    <a name=""></a><li>maximumTemperature &lt;value&gt;<br>
            For devices of type HeatingThermostat only. Writes the given maximum temperature to the device's memory. It confines the temperature that can be manually set on the device.</li>
    <a name=""></a><li>windowOpenTemperature &lt;value&gt;<br>
            For devices of type HeatingThermostat only. Writes the given window open temperature to the device's memory. That is the temperature the heater will temporarily set if an open window is detected. Setting it to 4.5 degree or "off" will turn off reacting on open windows.</li>
    <a name=""></a><li>windowOpenDuration &lt;value&gt;<br>
            For devices of type HeatingThermostat only. Writes the given window open duration to the device's memory. That is the duration the heater will temporarily set the window open temperature if an open window is detected by a rapid temperature decrease. (Not used if open window is detected by ShutterControl. Must be between 0 and 60 minutes in multiples of 5.</li>
    <a name=""></a><li>decalcification &lt;value&gt;<br>
        For devices of type HeatingThermostat only. Writes the given decalcification time to the device's memory. Value must be of format "Sat 12:00" with minutes being "00". Once per week during that time, the HeatingThermostat will open the valves shortly for decalcification.</li>
    <a name=""></a><li>boostDuration &lt;value&gt;<br>
        For devices of type HeatingThermostat only. Writes the given boost duration to the device's memory. Value must be one of 5, 10, 15, 20, 25, 30, 60. It is the duration of the boost function in minutes.</li>
    <a name=""></a><li>boostValveposition &lt;value&gt;<br>
        For devices of type HeatingThermostat only. Writes the given boost valveposition to the device's memory. It is the valve position in percent during the boost function.</li>
    <a name=""></a><li>maxValveSetting &lt;value&gt;<br>
        For devices of type HeatingThermostat only. Writes the given maximum valveposition to the device's memory. The heating thermostat will not open the valve more than this value (in percent).</li>
    <a name=""></a><li>valveOffset &lt;value&gt;<br>
        For devices of type HeatingThermostat only. Writes the given valve offset to the device's memory. The heating thermostat will add this to all computed valvepositions during control.</li>
    <a name=""></a><li>factoryReset<br>
        Resets the device to factory values. It has to be paired again afterwards.<br>
        ATTENTION: When using this on a ShutterContact using the MAXLAN backend, the ShutterContact has to be triggered once manually to complete
        the factoryReset.</li>
    <a name=""></a><li>associate &lt;value&gt;<br>
        Associated one device to another. &lt;value&gt; can be the name of MAX device or its 6-digit hex address.<br>
        Associating a ShutterContact to a {Heating,WallMounted}Thermostat makes it send message to that device to automatically lower temperature to windowOpenTemperature while the shutter is opened. The thermostat must be associated to the ShutterContact, too, to accept those messages.
        <b>!Attention: After sending this associate command to the ShutterContact, you have to press the button on the ShutterContact to wake it up and accept the command. See the log for a message regarding this!</b>
        Associating HeatingThermostat and WallMountedThermostat makes them sync their desiredTemperature and uses the measured temperature of the
 WallMountedThermostat for control.</li>
    <a name=""></a><li>deassociate &lt;value&gt;<br>
        Removes the association set by associate.</li>
    <a name=""></a><li>weekProfile [&lt;day&gt; &lt;temp1&gt;,&lt;until1&gt;,&lt;temp2&gt;,&lt;until2&gt;] [&lt;day&gt; &lt;temp1&gt;,&lt;until1&gt;,&lt;temp2&gt;,&lt;until2&gt;] ...<br>
      Allows setting the week profile. For devices of type HeatingThermostat or WallMountedThermostat only. Example:<br>
      <code>set MAX_12345 weekProfile Fri 24.5,6:00,12,15:00,5 Sat 7,4:30,19,12:55,6</code><br>
      sets the profile <br>
      <code>Friday: 24.5 &deg;C for 0:00 - 6:00, 12 &deg;C for 6:00 - 15:00, 5 &deg;C for 15:00 - 0:00<br>
      Saturday: 7 &deg;C for 0:00 - 4:30, 19 &deg;C for 4:30 - 12:55, 6 &deg;C for 12:55 - 0:00</code><br>

      Verbindet ein Ger&auml;t mit einem anderen. &lt;value&gt; kann entweder der Name eines MAX Ger&auml;tes oder
      seine 6-stellige hexadezimale Adresse sein.<br>
      Wenn ein Fensterkontakt mit einem HT/WT verbunden wird, sendet der Fensterkontakt automatisch die <code>windowOpen</code> Information wenn der Kontakt
      ge&ouml;ffnet ist. Das Thermostat muss ebenfalls mit dem Fensterkontakt verbunden werden, um diese Nachricht zu verarbeiten.
      <b>Achtung: Nach dem Senden der Botschaft zum Verbinden an den Fensterkontakt muss der Knopf am Fensterkontakt gedr&uuml;ckt werden um den Fensterkonakt aufzuwecken
      und den Befehl zu verarbeiten. Details &uuml;ber das erfolgreiche Verbinden finden sich in der Logdatei!</b>
      Das Verbinden eines Heizk&ouml;rperthermostates und eines Wandthermostates synchronisiert deren
      <code>desiredTemperature</code> und verwendet die am Wandthermostat gemessene Temperatur f&uuml;r die Regelung.</li>

    <a name="comfortTemperature"></a><li>comfortTemperature &lt;value&gt;<br>
      Nur f&uuml;r HT/WT. Schreibt die angegebene <code>comfort</code> Temperatur in den Speicher des Ger&auml;tes.<br>
      Diese kann durch dr&uuml;cken der Taste Halbmond/Stern am Ger&auml;t aktiviert werden.</li>

        Nur f&uuml;r HT/WT &lt;value&gt; kann einer aus folgenden Werten sein
        <ul>
          <li>Grad Celsius zwischen 4,5 und 30,5 Grad Celisus in 0,5 Grad Schritten</li>
          <li>"on" (30.5) oder "off" (4.5) versetzt den Thermostat in volle Heizleistung bzw. schaltet ihn ab</li>
          <li>"eco" oder "comfort" mit der eco/comfort Temperatur, die direkt am Ger&auml;t
              eingestellt wurde (&auml;nhlich wie die Halbmond/Stern Taste am Ger&auml;t selbst)</li>
          <li>"auto &lt;temperature&gt;". Damit wird das am Thermostat eingestellte Wochenprogramm
              abgearbeitet. Wenn optional die Temperatur &lt;temperature&gt; angegeben wird, wird diese
              bis zum n&auml;sten Schaltzeitpunkt des Wochenprogramms als <code>desiredTemperature</code> gesetzt.</li>
          <li>"boost" aktiviert den Boost Modus, wobei f&uuml;r <code>boostDuration</code> Minuten
              das Ventil <code>boostValveposition</code> Prozent ge&ouml;ffnet wird.</li>
        </ul>
        Alle Werte au&szlig;er "auto" k&ouml;nnen zus&auml;zlich den Wert "until" erhalten,
        wobei &lt;date&gt; in folgendem Format sein mu&szlig;: "TT.MM.JJJJ SS:MM"
        (Minuten nur 30 bzw. 00 !), um kurzzeitige eine andere Temperatur bis zu diesem Datum und dieser
        Zeit einzustellen. Wichtig : der Zeitpunkt muß in der Zukunft liegen !<br>
	Wenn dd.mm.yyyy dem heutigen Tag entspricht kann statdessen auch das Schl&uml;sselwort today verwendet werden.

    <a name="factoryReset"></a><li>factoryReset<br>
      Setzt das Ger&auml;t auf die Werkseinstellungen zur&uuml;ck. Das Ger&auml;t muss anschlie&szlig;end neu angelernt werden.<br>
      ACHTUNG: Wenn dies in Kombination mit einem Fensterkontakt und dem MAXLAN Modul
      verwendet wird, muss der Fensterkontakt einmal manuell ausgel&ouml;st werden, damit das Zur&uuml;cksetzen auf Werkseinstellungen beendet werden kann.</li>


    <a name="groupid"></a><li>groupid &lt;id&gt;<br>
      Nur f&uuml;r Heizk&ouml;rperthermostate.
      Schreibt die angegebene Gruppen ID in den Speicher des Ger&auml;tes.
      Um alle Ger&auml;te in einem Raum zu synchronisieren, k&ouml;nnen diese derselben Gruppen ID
      zugeordnet werden, diese mu&szlig; gr&ouml;&szlig;er Null sein.</li>

    <a name="measurementOffset"></a><li>measurementOffset &lt;value&gt;<br>
      Nur f&uuml;r Heizk&ouml;rperthermostate. Schreibt die angegebene <code>offset</code> Temperatur in den Speicher
      des Ger&auml;tes. Wenn der interne Temperatursensor nicht korrekt kalibriert ist, kann dieses einen
      systematischen Fehler erzeugen. Mit dem Wert <code>measurementOffset</code>, kann dieser Fehler
      kompensiert werden. Die ausgelese Temperatur ist gleich der gemessenen
      Temperatur + <code>measurementOffset</code>. Normalerweise ist die intern gemessene Temperatur h&ouml;her
      als die Raumtemperatur, da der Sensor n&auml;her am Heizk&ouml;rper ist und man verwendet einen
      kleinen negativen Offset, der zwischen -3,5 und 3,5 Kelvin sein mu&szlig;.</li>

      Nur f&uuml;r Heizk&ouml;rperthermostate. Schreibt die angegemene <code>window open</code> Temperatur in den Speicher
      des Ger&auml;tes. Das ist die Tempereratur, die an der Heizung kurzfristig eingestellt wird, wenn ein
      ge&ouml;ffnetes Fenster erkannt wird. Der Wert 4,5 Grad bzw. "off" schaltet die Reaktion auf
      ein offenes Fenster aus.</li>
    <a name="windowOpenDuration"></a><li>windowOpenDuration &lt;value&gt;<br>
      Nur f&uuml;r Heizk&ouml;rperthermostate. Schreibt die angegebene <code>window</code> open Dauer in den Speicher
      des Ger&auml;tes. Dies ist die Dauer, w&auml;hrend der die Heizung kurzfristig die window open Temperatur
      einstellt, wenn ein offenes Fenster durch einen schnellen Temperatursturz erkannt wird.
      (Wird nicht verwendet, wenn das offene Fenster von <code>ShutterControl</code> erkannt wird.)
