Fire PGM
The fire control PGM is monitored NOT controlled by the function and when the fire PGM has been activated,
typically by an external fire alarm input, the RTHP will gracefully shut down the air conditioning system and halt
operation until the fire alarm has been cleared. This PGM could be the PGM used to deactivate smoke dampers
and other related equipment in the HVAC control system.
FN001 Fire
pgm: --000:00
To modify the fire PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
336). Do not set a PGM group for the fire or other monitored PGM's as this will have no action in the control
system and will be the same as not setting a PGM value.
Fan Control PGM
The fan PGM is activated when the RTHP starts to operate and is started 30 seconds prior to any heating,
cooling or dehumidification is required allowing it to ramp up to the desired speed.
FN001 Fan
pgm: --000:00
To modify the fan PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
336).
Cooling Stage 1 PGM
The cool 1 PGM is activated when the RTHP has a requirement for cooling and the cooling stage demand value
has been exceeded for the first stage. The cooling 1 PGM will typically be used to control the first stage of the
cooling system.
FN001 Cool 1
pgm: --000:00
To modify the cool 1 PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
336).
Cooling Stage 2 PGM
The cool 2 PGM is activated when the RTHP has a requirement for cooling and the cooling stage demand value
has been exceeded for the second stage. The cooling 2 PGM will typically be used to control the second stage
of the cooling system.
FN001 Cool 2
pgm: --000:00
To modify the cool 2 PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
336).
Cooling Stage 3 PGM
The cool 1 PGM is activated when the RTHP has a requirement for cooling and the cooling stage demand value
has been exceeded for the third stage. The cooling 3 PGM will typically be used to control the third stage of the
cooling system.
FN001 Cool 3
pgm: --000:00
To modify the cool 3 PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
