Dear TRNSYS users,
I'm trying to model a domestic hot water using the type 156 for water storage. The pump is controlled by the type 165 (2-5 °C as hysteresis). But the difference between the temperature at the outlet of the collector and the lower tank temperature
is always higher than 2°C. So the pump is always ON. When I checked in the plotter, it seems like the temperature is equal to the temperature of the immersed heat exchanger even at night when there's no radiation.
Can anyone help me fix this please ?
Regards,
Amadou
