Order No. 2104 ..
The "deadband between heating and cooling", "deadband position" parameters as well as the
"Basic temperature after reset" parameter are preset in the ETS configuration. One
distinguishes between the following settings...
-
deadband = "symmetrical"
The deadband preset in the ETS is divided into two parts at the basic setpoint. The comfort
setpoint temperatures are derived directly from the basic setpoint resulting from the half
deadband.
The following applies...
T
Basic setpoint
– ½T
deadband
= T
Comfort heating setpoint
and
T
Basic setpoint
+ ½T
deadband
= T
Comfort setpoint cooling
-> T
Comfort cooling setpoint
– T
Comfort heating setpoint
= T
deadband
-> T
Comfort cooling setpoint
≥ T
Comfort heating setpoint
-
deadband position = "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 setpoint in the direction of
comfort temperature for cooling. Thus the comfort set-temperature for cooling is derived
directly from the comfort setpoint for heating.
The following applies...
T
Basic setpoint
= T
Comfort heating setpoint
-> T
Basic setpoint
+ T
deadband
= T
Comfort cooling setpoint
-> T
Comfort cooling setpoint
– T
Comfort heating setpoint
= T
deadband
-> T
Comfort cooling setpoint
≥ T
Comfort heating setpoint
