224 PRT-CTRL-SE Protege System Controller Reference Manual | PRT-CTRL-SE
Register Offset Register Function
17 Fault Condition
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.
18 Fire Condition
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 333) and press [ENTER].
i
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.
Space Humidity Register
The space humidity register is the register that is updated by an analogue module input channel connected to a
humidity sensor. The space humidity sensor is typically located within the space the RTHP is controlling at a
height of 1.5 to 2.5 meters above floor level.
FN001 Space rh
reg: 00000
To modify the space humidity register (00000 to 65535, use the keypad as explained in section Entering
Decimal Numbers (see page 333) and press [ENTER].
External Fresh Air Temperature Register
The external fresh air temperature register is the register that is updated by an analogue module input channel
connected to a temperature sensor. The external fresh air temperature is typically from a sensor located within
fresh air intake of the RTHP in the cowling section. The fresh air temperature sensor is used to calculate the
ability to cool the space with direct fresh air and is calculated prior to a demand for cooling.
FN001 Fresh temp
reg: 00000
To modify the fresh temperature register (00000 to 65535, use the keypad as explained in section Entering
Decimal Numbers (see page 333) and press [ENTER].
