[TRNSYS-users] Type4 - control strategy

[Amandine LE DENN]

Dear Trnsys users,

I would like to use Type4 storage tank with one auxiliary heater, only controlled by a ON/OFF controller (Type2). 
However, it seems that the other conditions (temperature conditions inside the tank: Tthermostat < Tset and Tnode < Tset - Tdb) already control the ON/OFF cycle of the auxiliary heater. 
What can I do to avoid those two conditions ? If I give the same value to Tdb and Tset , auxiliary heater doesn't work.
I modeled a tank with one node.

Thank you for your answers,
