In the case of switching 2-point feedback control, the hysteresis values must
additionally be taken into account.
Deadband and deadband positions in the combined heating and cooling operating
mode
With relative setpoint presetting, the comfort setpoint temperatures for heating and
cooling are derived from the basic setpoint in consideration of the set deadband. The
deadband (temperature zone for which there is neither heating nor cooling) is the dif-
ference between the comfort setpoint temperatures. This deadband does not exist for
absolute setpoint presetting.
The parameters "Deadband between heating and cooling", "Allocation of deadband"
and "Basic setpoint temperature" are specified in the ETS configuration. One distin-
guishes between the following settings...
– Allocation of deadband = "symmetrical"
The deadband preset in the ETS is divided into two parts at the basic setpoint.
Based on the resulting half deadband, the comfort setpoint temperatures are
derived directly from the basic setpoint.
The following applies...

Comfort setpoint cooling
– Allocation of deadband = "asymmetrical"
With this setting the comfort setpoint temperature for heating equals the basic
setpoint. The deadband preset in the ETS is effective only from the basic set-
point in the direction of comfort temperature for cooling. Thus the comfort set-
temperature for cooling is derived directly from the comfort setpoint for heat-
ing.
