3.6.7 Compressor applications (RDF800KN.., RDF800KN/VB
only)
For compressor applications, proceed as follows:
1. Set the corresponding basic application
2. Disable the fan (P52) or set the fan speed (P53)
The following applications are available:

· Minimum On/Off time:
· Fan operation:P52 (0 = disabled, 1 = enabled)
· Fan speed: P53 (1 = 1-speed, 2 = 3-speed)
3.6.8 Setpoints and sequences (RDF800KN.., RDF800KN/VB
only)
On changeover applications, the Comfort setpoints for heating and cooling
sequence are the same (w).
On 2-pipe applications with electric heater, the Comfort setpoint is either at the first
heating sequence (in heating mode) or at the cooling sequence (in cooling mode).
The setpoints for Economy and Protection mode are below the Comfort setpoints
(heating) and above the Comfort setpoints (cooling), which can be set using P11,
P12 (Economy mode) and P65, P66 (Protection mode).
