Register Function
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.
15 Dehumidification Stage Off
16 RTHP Shutting Down
17 Fault Condition
18 Fire Condition
Dehumidification stages are deactivated because the humidity has reached set point and
dehumidification is no longer required.
The RTHP is completing an orderly shutdown of the currently activated stages and the
fan control signals.
A fault condition has activated that has caused the RTHP to shut down. This condition is
typical of a smoke damper closing or other mechanical input that will result in the RTHP
shutting down.
A fire alarm condition has been activated that has caused the RTHP to shut down.
Space Temperature Register
The space temperature register is the register that is updated by an analogue module input channel connected
to a temperature sensor. The space temperature is typically from a sensor located within the space the RTHP is
controlling.
FN001 Space temp
reg: 00000
To modify the space temperature register (00000 to 65535, use the keypad as explained in section Entering
Decimal Numbers (see page 341) and press [ENTER].

If you are unsure how the RTHP operates and what action is going to be started as a result in the
change in the input registers you can specify the register to be a normal register outside the analogue
module range. This will allow an installer to modify the values with the Protege System Management
Suite and visually see the mode change in the RTHP without the need to physically connect the RTHP.
