Outside temperature adjustment (yellow)
The WRG 3010 E has the possibility of outside temperature adjustment. The desired setpoint for HT and LT at
a outside temperature of +15 °C is set in this field. The setpoint is entered separately for the flow and return
temperature of the respective heat exchanger. The current outside temperature (analogue input Pt1000,
terminals 1, 2, 3, 4) is located in the yellow field at the top right. If no outside temperature sensor has been
connected to the input or if there is a sensor break, the outside temperature from the
interconnection controller
which is transmitted from it via the CAN bus is used.
The function is activated if the button "adjustment via outside temperature" has been operated. In this case, the
gradient is determined with the "offset heating curve" parameter, whereby the entered offset applies to an
outside temperature of -15 °C. The gradient applies equally to HT and LT. The setpoint is then adjusted
depending on the outside temperature and the gradient. To prevent possible overheating, e.g. during very low
night frosts, a maximum increase can still be set. The resulting setpoint for HT and LT is located directly below
the respective setpoint.
Example: The setpoint HT flow is set to 55 °C, the parameter "offset heating curve" is set to 5 Kelvin, the
parameter "max increase heating" is set to 7 Kelvin and the outside temperature is -9.1 °C. In this case, the
calculated new setpoint would be 59 °C.
