Heating Stage 2 PGM
The heat 2 PGM is activated when the RTHP has a requirement for heating and the heating stage demand value
has been exceeded for the second stage. The heating 2 PGM will typically be used to control the second stage
of the heating system.
FN001 Heat 2
pgm: --000:00
To modify the heat 2 PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
345).
Heating Stage 3 PGM
The heat 3 PGM is activated when the RTHP has a requirement for heating and the heating stage demand value
has been exceeded for the third stage. The heating 3 PGM will typically be used to control the third stage of the
heating system.
FN001 Heat 3
pgm: --000:00
To modify the heat 3 PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
345).
Heating Stage 4 PGM
The heat 4 PGM is activated when the RTHP has a requirement for heating and the heating stage demand value
has been exceeded for the fourth stage. The heating 4 PGM will typically be used to control the fourth stage of
the heating system.
FN001 Heat 4
pgm: --000:00
To modify the heat 4 PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
345).
Dehumidification Stage 1 PGM
The dehumidification stage 1 PGM is activated when the RTHP has a requirement for dehumidification. The
dehumidification process will typically open the first stage of the hot gas reheat valves located in the RTHP unit.
FN001 Dehumid 1
pgm: --000:00
To modify the dehumidification stage 1 PGM, use the settings as explained in section Entering PGM and PGM
Groups (see page 345).
Dehumidification Stage 2 PGM
The dehumidification stage 2 PGM is activated when the RTHP has a requirement for dehumidification and the
humidity is above the hysteresis value plus the setpoint. The dehumidification process will typically open the
second stage of hot gas reheat valves located in the RTHP unit.
FN001 Dehumid 2
pgm: --000:00
To modify the dehumidification stage 2 PGM, use the settings as explained in section Entering PGM and PGM
Groups (see page 345).
