dehumidification.
5 On Call For Space Heating
The space temperature is below the heating set point and the
function to start the heating process is active. This will activate the
stages required to bring the temperature up to the heating set
point.
6 On Call For Space Cooling
The space temperature is above the cooling set point and the
function to start the cooling process is active. This will activate the
stages required to bring the temperature down to the cooling set
point.
7 On Call For Fresh Air Space Cooling
The space temperature is above the cooling set point and the
outside air is below the free air cooling set point, the RTHP will
oscillate the fresh air economizer in attempt to cool the space
using the fresh air intake. This will remain active until the
temperature is below the cooling set point or if the free cooling
fails to achieve set point in the set time (Free Cooling Time) mode
6 will be entered.
8 Heating Stage Off
Heating stages are being turned off progressively due to the set
point being reached.
9 Cooling Stage Off
Cooling stages are being turned off progressively due to the set
point being reached.
10 Dehumidification Cooling Plus Reheat
Dehumidification is required and the current set point is above the
cooling set point. The dehumidification stage will be entered in an
attempt to get the humidity under control.
11 Dehumidification Transition
The dehumidification process is in a transition between the
dehumidification requirements and cooling.
12 Dehumidification Heating
Dehumidification is required and the current set point is below the
heating set point. The dehumidification stage will be entered in an
attempt to get the humidity under control while an attempt is also
made to obtain heating set point.
13 Dehumidification Heating Stage Off
Dehumidification and heating stages are deactivated because the
humidity has come under control or the cooling set point (other
side of the dead band setting) has been reached.
14 Dehumidification Cooling Stage Off
Dehumidification and cooling stages are deactivated because the
humidity has come under control or the heating set point (other
side of the dead band setting) has been reached.
