0 Heating Set Point
The heating set point determines the temperature that the RTHP
will heat the space to and is compared with the temperature
sensor connected to the Space Temp input.
1 Cooling Set Point
The cooling set point determines the temperature that the RTHP
will cool the space to and is compared with the temperature sensor
connected to the Space Temp input.
2 Relative Humidity Set Point
The relative humidity set point determines at what humidity level
the RTHP will go in to a dehumidification cycle and drive the plant
to reduce this amount. The relative humidity set point when
exceeded is added or subtracted using the Hystersis value to
prevent osciallation of the hyumidty modes.
3 Heating Hysterisis Setting
The heating hysterisis value is added to the heating set point to
allow the plant to drive slightly beyond the set point. This allows
specific heating and cooling tuning. Setting a value of 0 is not
recommended as it can cause the system to oscillate between the
dead band the heating modes.
4 Cooling Hysterisis Setting
The cooling hysterisis value is subtracted from the cooling set
point to allow the plant to drive slightly below the set point. This
allows specific heating and cooling tuning. Setting a value of 0 is
not recommended as it can cause the system to oscillate between
the dead band the cooling modes.
5 Relative Humidity Hysterisis Setting
The relative humidity hysterisis value is subtracted or added
depending if the set point has already been exceeded to the
relative humidity set point. This allows the relative humidity cycles
to be tuned. Setting a value of 0 is not recommended as it can
cause the system to oscillate between the relative humidity states.
6 Warm Up Set Point
If the warm up set point is not equal to 0 the system will check the
space temperature against the warm up set point when the
occupied relay is activated. If the internal temp is below the warm
up set point the system will close the fresh air damper and drive
the heating to achieve the heating set point. Once set point is
reached the unit will operate in a normal mode.
