Dear Trnsys users,
I am using Type 121b as a preheater for the outdoor
air. I combined the heater with a controller (type2) that
makes sure the air is heated whenever the
outdoor air temperature is below 16°C. This controller gives a control function
to type 121b. I've put
the setpoint of the heater to 16°C.
(I ignore heat losses), but every time the
outdoor temperature is already 16°C before heating up,
the heater heats still heats up the air and the temperature becomes > 50 or 60°C.
Can someone help me with this?
Kind regards,
