Stage 3 / Mist (POS 4)
Relative Temperature Stage 3 / Mist
This parameter is used to establish the relative temperature at which stage
3 / mist will activate. When the
Average Temperature
reaches
Main Set
Point
+
Relative Temperature Stage 3 / Mist
, stage 3 / mist will activate
according to its cycle. This parameter is adjusted in 0.1° increments from
0.5°F to 20.0°F (0.3°C to 11.1°C).
Stage 3 / Mist Cycle
CyC
This parameter is used to establish the duration of the run time for the mist
timer. When the
Average Temperature
is equal to or above
Main Set
Point
+
Relative Temperature Stage 3 / Mist
, stage 3 / mist will be
activated for a percentage (
Stage 3 / Mist Cycle
) of the 12 minute mist
period. If
Stage 3 / Mist Cycle
is set to
ON
, stage 3 / mist will be
continuously activated when an activation demand occurs. If
Stage 3 / Mist
Cycle
is set to
Off
, stage 3 / mist will never activate regardless of the
Average Temperature
. This parameter is adjusted in 1% increments from
OFF
, 1 to 99%,
ON
.
Stage 3 / Mist Humidity Shutoff
RHOFF
This parameter is used to establish the humidity level at which stage 3 will
shut off. When
Humidity Probe
reaches this value, stage 3 will deactivate.
A fixed differential of 3RH% is used with this logic. Setting this parameter to
OFF
will deactivate the humidity shut off logic. This parameter is adjusted
in 1RH% increments from 0 to 99RH%,
OFF
.
Stage 4 / Heater 2 (POS 5)
Relative Temperature Stage 4 / Heater 2
This parameter is used to establish the relative temperature at which stage
4 / heater 2 will activate. If
Logic Out 4
is set to
COOL
, stage 4 will
activate when the
Average Temperature
is equal to or above
Main Set
Point
+
Relative Temperature Stage 4 / Heater 2
. If
Logic Out 4
is set to
HeAT
, heater 2 will activate when the
Average Temperature
of the
probes selected in
Heater 2 Probe {1-4}
is equal to or below
Main Set
Point
+
Relative Temperature Stage 4 / Heater 2
. If DIPSW7 is OFF (see
DIP Switches and Slide Switches Table page 38), stage 3 / mist will shut off
as long as stage 4 is activated and
Logic Out 4
is set to
COOL
. This
parameter is adjusted in 0.1° increments from -20.0°F to 20.0°F (-11.1°C to
11.1°C).
