18 Period time for heating actuator if thermal
actuators.
480 s
19 Period time for cooling actuator if thermal
actuators.
480 s
20 Run time for heating actuator with increase/decrease actuators. 120 s
21 Run time for cooling actuator with increase/decrease actuators. 120 s
22 Time (in hours) between exercise of heating actuator. 23
23 Time (in hours) between exercise of cooling actuator. 23
24 Setpoint or actual value shown in display:
0=Actual, setpoint when changing setpoint value
1=Actual, setpoint adjustment when changing setpoint value
2=Setpoint
3=Only setpoint adjustment

25 Configuration of fan control:
0=No control
1=The fan is controlled by the heating requirement
2=The fan is controlled by the cooling requirement
3=The fan is controlled by both the heating and cooling requirement
When using an electric heater this parameter should only be set to 1 or 3,
otherwise there is a risk of overheating.
