Summer compensation
Note
This parameter is only available if the "Device function" parameter is set on
either "Single device" or "Master device".
11.4.6
Summer compensation — Summer compensation
Options:
In order to save energy, and to ensure that the temperature difference occurring during entry
and exit of a climate-controlled building stays within comfortable limits, the excessive reduction
of room temperature should be prevented during high temperatures in the summer ( Summer
compensation according to DIN 1946). The room temperature is increased by adjusting the
setpoint temperature for cooling.
Raising the room temperature does not, however, mean that you heat up the room. Rather, the
adjustment is intended to allow the room temperature to increase to a certain setpoint without
cooling. This, for example, prevents the air-conditioning system from further reducing the room
temperature to 24°C with an external temperature of 35°C.
However, activation of the summer compensation requires an outside temperature sensor that
transmits its measured value to the bus and can be evaluated by the room temperature
controller.
The following parameters are available for summer compensation:
"Lower outside temperature value for summer compensation",
■
"Upper outside temperature value for summer compensation",
■
"Lower setpoint offset for summer compensation",
■
"Upper setpoint offset for summer compensation"
■
Above the "Upper outside temperature value", the minimum setpoint temperature for cooling is
the outside temperature minus the "Upper setpoint offset". The outside temperature has no
effect on the minimum setpoint temperature for cooling below the "Lower outside temperature
value". Between the "Lower" and "Upper outside temperature value", the minimum setpoint
temperature for cooling undergoes floating adjustment by the parameterized setpoint
temperature equal to the outside temperature minus the "Lower offset" to a value equal to the
outside temperature minus the "Upper setpoint offset" as a function of the outside temperature.
