4.3.6 Setpoint and sequences
2-pipe applications
In changeover applications, the Comfort setpoints (W) for the heating and
cooling sequence are the same.
In 2-pipe applications with electric heater, the Comfort setpoint is either in the
first heating sequence (in heating mode) or in the cooling sequence (in cooling
mode).
The setpoints for Standby (Economy) mode and Protection mode are below the
Comfort setpoint for heating and above the Comfort setpoint for cooling.
The heating and cooling setpoints for Standby (Economy) mode can be set via
parameters P06 and P07.
