PRT CTRL Integrated Controller Reference Manual

Dehumidification stages are deactivated because the humidity has
reached set point and dehumidification is no longer required.
16 RTHP Shutting Down
The RTHP is completing an orderly shutdown of the currently
activated stages and the fan control signals.
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 on Page 405 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 Protégé 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 on Page 405 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.
