+# 07.10.15 GA initial version published
+
+# module for PWM (Pulse Width Modulation) calculation
+# this module defines a room for calculation 
+# it is used by a PWM object 
+# reference to the PWM object is via IODev
+# PWMR object defines:
+#  IODev: reference to PWM
+#  factor (also used in PID calculation): 
+#     temperatur difference * factor * cycletime (from PWM) defines on/off periods (pulse)
+#  sensor delivering the temperature (temperature is read from reading using a regexp)
+#  actor to switch on/off the heating devices (may be a structure if more than on actor..)
+#  comma separated list of window contacts followd by ":" and a regular expression 
+#     default for the regular expression is "Open"
+#     if the regular expression matches on of the contacts 
+#     then readRoom will return c_tempFrostProtect as desired-temp
+#     instead of the current calculated desired-temp
+#     this should cause the calculation routine for the room to switch off heating
+#
+# calculation of "desired-temp" is done in a loop (5-minutes default)
+#  - if c_frostProtect is "1" -> set to c_tempFrostProtect
+#  - if c_autoCalcTemp is "1" -> use c_tempN, c_tempD, c_tempC, c_tempE and c_tempRule[1-5]
+#  - c_* variables are syntax checked and derived from attr which have a readable syntax
+# 
+#  - c_tempRule[1-5] are processed in order 5..1 (5 is highes priority)
+#    rules define: 
+#    <interval of valid days (0..6 = So..Sa)
+#    <time>,[N|D|C] [<time>,[N|D|C|E]] 
+#      ... time is interpreted as Hour[:Min]       
+#      ... N,D,C,E reference timeN (Night), timeD (Day), timeC (Cosy), timeE(Energysave)
+# 
+#    attr names are: tempDay, tempCosy, tempNight, tempEnergy ...
+#
+# subroutines PWMR_ReedRoom and PWMR_SetRoom are called from PWM object

+  The PMWR module defines rooms to be used for calculation within module PWM.<br><br>
+  PWM is based on Pulse Width Modulation which means valve position 70% is implemented in switching the device on for 70% and off for 30% in a given timeframe.<br>
+  PWM defines a calculation unit and depents on objects based on PWMR which define the rooms to be heated.<br>
+  PWMR objects calculate a desired temperature for a room based on several rules, define windows, a temperature sensor and an actor to be used to switch on/off heating.

+
+    <br>
+    Define a calculation object with the following parameters:<br>
+    <ul>
+    <li>IODev<br>
+      Reference to an object of TYPE PWM. This object will switch on/off heating.<br>
+    </li>
+
+    <li>factor[,offset]<br>
+      Pulse for PWM will be calculated as ((delta-temp * factor) ** 2) + offset.<br>
+      <i>offset</i> defaults to 0.11<br>
+      <i>factor</i> can be used to weight rooms.<br>
+    </li>
+
+    <li>tsensor[:reading:t_regexp]<br>
+      <i>tsensor</i> defines the temperature sensor for the actual room temperature.<br>
+      <i>reading</i> defines the reading of the temperature sensor. Default is "temperature"<br>
+      <i>t_regexp</i> defines a regular expression to be applied to the reading. Default is '([\\d\\.]*)'.<br>
+    </li>
+
+    <li>actor<br>
+      The actor will be set to "on" of "off" to turn on/off heating.<br>
+    </li>
+
+    <li>window[,window]:w_regexp<br>
+      <i>window</i> defines several window devices that can prevent heating to be turned on. 
+      If STATE matches the regular expression then the desired-temp will be decreased to frost-protect temperature.<br>
+      <i>w_regexp</i> defines a regular expression to be applied to the reading. Default is '.*Open.*'.<br>
