Temperature setpoints

2.4.1

Setpoint presettings in the ETS

Temperature setpoints can be preset independently for each operating mode. The setpoints for the "comfort ",
"standby " und "night " modes can be parameterized in the ETS. If desired, the setpoint temperatures can be
subsequently adjusted via object control. The "frost/heat protection " operating mode allows the separate
parameterization of two temperature setpoints for heating (frost protection) and cooling (heat protection) only in
the ETS.
When presetting the setpoint temperatures for comfort, standby and night mode, attention has to be paid to the
fact that all setpoints depend on each other as all values are derived from the basic temperature (basic setpoint).
The "Basic temperature after reset" parameter on the "Setpoints" parameter page determines the basic setpoint
which is loaded when the device is programmed with the ETS.
Taking into account the "Decreasing /increasing the setpoint temperature in standby mode" or
"Decreasing/ increasing the setpoint temperature in night mode" parameters, the temperature setpoints for the
standby and night mode are derived from this value depending on the heating or cooling control option. The dead
zone will be additionally considered for the "heating and cooling" mode.
In two stage control mode, all setpoint temperatures of the additional stage are derived from the setpoint
temperatures of the basic stage. The setpoint temperatures of the additional stage are determined by subtracting
the "stage offset" , which is parameterized in the ETS from the setpoints of the basic stage in heating mode or by
adding the setpoints in cooling mode. If the temperature setpoints of the basic stage are changed by setting a new
basic setpoint, the setpoint temperatures of the additional stage will be indirectly and automatically changed as well.
Both stages will heat or cool with the same actuating variable at the same time when the setpoint difference is "0".
Depending on the control option, the relationships described on the following pages have to be considered for the
setpoint temperatures.
