<p class="MsoNormal"><span lang="EN-GB">I am modelling a floor heating system in of a house in combination with a heat pump. The heat pump is not only heating the floor but also a water storage tank. The system works as follows:
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">The storage tank gets heated up once every 24h till 60 degrees, when this happens the floor heating is getting bypassed.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"> There is one pump that I am trying to get controlled by both systems : when the room temperature become too low, controlled with a simple thermostat, signal turn 1 and another controller where the signal is 1 at midnight
for couple of hours to heat up the storage tank. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">So I would like to have for example a OR-function to the control the pump. Is there something like that?<o:p></o:p></span></p>
