[TRNSYS-users] About Type4e

[David BRADLEY]

Anas,
  You have specified a thermostat set point of 45C and a thermostat 
deadband of 5C which means that the heater in your tank will not turn on 
until the temperature of the node containing the thermostat (node 1 in 
your case) reaches 40C (45-5) and once on, will stay on until the set 
point is reached. In your case the tank does not reach 40C by the end of 
the first 24 hour period (the end of your simulation). Click on the 
"more" button next to parameters, inputs, and outputs to learn how their 
values affect the simulation.
regards,
  David
