# module for PWM (Pulse Width Modulation) calculation
|
|
# this module uses PWMR (R like room) to
|
|
# - get information (ReadRoom)
|
|
# - set actors (SetRoom)
|
|
#
|
|
# standard heating devices support 0 to 100% heating they can be driven by the PID module
|
|
# heating devices only supporing "on" of "off" can be driven by PWM
|
|
# in PWM 50% is realised by defining a timeframe (cycletime)
|
|
# and switch the defive "on" for 50% of this time
|
|
# basis for calculation of this pulse is a factor multiplied with the difference
|
|
# between desired-temp and act-temp
|
|
#
|
|
# default for cycletime is 15 minutes (900 sec)
|
|
# since the devices act very slow
|
|
# there is a parameter minonofftime to prevent "senseless" switches
|
|
# PWM recalculates the needed pulse every 60 seconds and
|
|
# then decides if the devices will be switched
|
|
# "on->off", "off->on" or stays in the current state
|
|

|
|
The PMW module implements temperature regulation for heating systems only capeable of switching on/off.<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>

<ul>
|
|
<code>define <name> PWM [<interval>] [<cycletime>] [<minonofftime>] [<maxPulse>] [<maxSwitchOnPerCycle>,<maxSwitchOffPerCycle>] [<roomStayOn>,<roomStayOff>,<stayOnThreshold>]<br></code>
|
|
<br>
|
|
Define a calculation object with the following parameters:<br>
|
|
<ul>
|
|
<li>interval<br>
|
|
Calculate the pulses every <i>interval</i> seconds. Default is 60 seconds.<br>
|
|
</li>
|
|
|
|
<li>cycletime<br>
|
|
Timeframe to which the pulses refere to. Default is 900 seconds (=15 Minutes). "valve position" of 100% calculates to "on" for this period.<br>
|
|
</li>
|
|
|
|
<li>minonofftime<br>
|
|
Default is 120 seconds.
|
|
Floor heating systems are driven by thermomechanic elements which react very slow. on/off status changes for lower periods are ignored.<br>
|
|
</li>
|
|
|
|
<li>maxPulse<br>
|
|
Default is 1, which means that a device can be switched on for the full <i>cylcetime</i> period.<br>
|
|
For energy saving reasons it may be wanted to prevent situations were all rooms are switched on (high energy usage) and afterwards off.<br>
|
|
In this case <i>maxPulse</i> is set to 0.85 (=12:45 minutes) which forces a room with a pulse of 1 (=100%) to be switched off after 12:45 minutes to give another
|
|
room the chance to be switched on.
|
|
<br>
|
|
</li>
|
|
|
|
<li>maxSwitchOnPerCycle,maxSwitchoffPerCycle<br>
|
|
Defaults are 99 for both values. This means that 99 PWMR object can be switched on or off at the same time.<br>
|
|
To prevent energy usage peaks followend by "no energy consumption" situations set both values to "1".<br>
|
|
This means after the room the the least energy required is switched off the next will be switched off.<br>
|
|
Rooms are switched on or off one after the other (in <interval> cycles) and not all at one time.<br>
|
|
Waiting times are honored by a addon to the pulse.<br>
|
|
<br>
|
|
</li>
|
|
|
|
<li>roomStayOn,roomStayOff,stayOnThreshold<br>
|
|
Defauts: <br>
|
|
<i>roomStayOn</i> = 0 ... all rooms can be switched off at the same time.<br>
|
|
<i>roomStayOff</i> = 0 ... all rooms can be switched on at the same time.<br>
|
|
<i>stayOnThreshold</i> = 0 ... no impact.<br>
|
|
For energy saving reasons the following may be set: "4,1,0.25". This means:<br>
|
|
The room with the least pulse will be kept off (<i>roomsStayOff</i>=1)<br>
|
|
If the average pulse for the (<i>roomsStayOn</i>=4) rooms with the most heating required is greater than (<i>stayOnThreshold</i>=0.25) then <i>maxRoomStayOn</i> will be kept in state "on", even it the time for the current pulse is reached.
|
|
If the threshold is not reached (not so much heating required) then all rooms can be switched off at the same time.<br>
