Set Point (POS 1)

Main Set Point
This is the temperature goal for the room, the activation temperature for
stage 1 and the reference temperature for all relative settings. The Main
Set Point will follow its growth curve when the Growth Day is not
and the MSP Curve option is set to
of four day-points and four temperature-points. To adjust these points,
press the SET/CLR button. Then select the point to adjust using the F2
button and adjust it with the adjustment knob. See the Additional
information on parameters section for more information on the growth
curve. The Main Set Point is adjusted in 0.1° increments from
-40.0°F to 100.0°F (-40.0°C to 37.8°C).

TIMER
Stage 1 Cycle
This parameter is used to establish the duration of the run time for the stage
1 timer. When the Average Temperature is below Main Set Point, stage 1
will be activated for a percentage (Stage 1 Cycle) of the Stage 1 Period. If
Stage 1 Cycle is set to OFF, stage 1 will never activate below Main Set
Point. If Stage 1 Cycle is set to ON, stage 1 will be continuously activated
below Main Set Point. This parameter is adjusted in 1% increments from
OFF, 1% to 99%, ON.
Stage 1 Period Per
This parameter is used to establish the duration of the period for the stage 1
timer. When the Average Temperature is below Main Set Point, stage 1
will be activated for a percentage (Stage 1 Cycle) of this period. This
parameter is adjusted in 1-minute increments from 1 to 10 minutes.

Stage 2 (POS 3)

REL
Relative Temperature Stage 2
This parameter is used to establish the relative temperature at which stage
2 will activate. When the Average Temperature reaches Main Set Point +
Relative Temperature Stage 2, stage 2 will activate. If DIPSW6 is OFF
(see DIP Switches and Slide Switches Table page 38), stage 1 will shut off
as long as stage 2 is activated. This parameter is adjusted in 0.1°
increments from 0.5°F to 20.0°F (0.3°C to 11.1°C).
