MINIMUM RAMP RATE
Minimum Cool and heat recovery ramp rates are selectable
from 0 to 20 DDF/hr. (0 to 11 DDC/hr.). A ramp rate of 0
means no recovery ramp (the setpoint steps from one setpoint
to the other).
The recovery ramp rate will vary as a function of outdoor
temperature.
MAX RAMP RATE
Maximum Cool and heat recovery ramp rates are selectable
from 0 to 20 DDF/hr. (0 to 11 DDC/hr.). A ramp rate of 0
means no recovery ramp (the setpoint steps from one setpoint
to the other). This field is enabled only if the outdoor air
temperature input is configured on the General Page.
OAT MIN RAMP
The minimum and maximum outdoor corresponds to the
minimum and maximum recovery rate. Configure the Outdoor
air temperature setpoint for cool and heat recovery at which
the minimum rate is equal to the value specified in the cool
and heat ‘Min Ramp Rate’ fields. The value is configurable
from –20 to 100 °F (-29 to 38 °C). This option is available to
configure only if the outdoor air temperature input on the
General page is configured.
OAT MAX RAMP
The minimum and maximum outdoor corresponds to the
minimum and maximum recovery rate. Configure the Outdoor
air temperature setpoint for cool and heat recovery at which
the maximum rate is equal to the value specified in the cool
and heat ‘Max Ramp Rate’ fields. The value is configurable
from –20 to 100 °F (-29 to 38 °C). This option is available to
configure only if the outdoor air temperature input on the
General page is configured.
RECOVERY LEAD TIME INFORMATION
The setpoint ramp will be at the target setpoint 10 minutes
prior to the occupied/standby event time. This allows the
HVAC equipment an extra 10 minutes to get the space
temperature to the target setpoint during recovery. (The
T7300 series 1000 did a similar method). Based on the heat
and cool setpoints configured and the minimum and maximum
ramp rates configured, the wizard automatically calculates the
lead time information for both cool and heat recovery ramps
and displays it in this section.
NOTE: This data is applicable when the unoccupied
setpoints change to occupied or standby modes.
When the setpoint changes from occupied or standby mode to
unoccupied mode or when the minimum or maximum ramp
rates are 0, there will be step change in the setpoint.
BYPASS
The temporary override time is the maximum time the
controller stays in the occupied mode, when its unoccupied
mode was overridden and put in bypass mode. This value is
selectable from 1 to 8 hours.
When no outdoor air temperature sensor is available, the
minimum recovery ramp rate is used. The recovery ramps
have the following configuration parameters:
• Minimum heating recovery ramp rate.
• Maximum heating recovery ramp rate.
• Minimum heating outdoor air temperature.
• Maximum heating outdoor air temperature.
• Minimum cooling recovery ramp rate.
• Maximum cooling recovery ramp rate.
• Minimum cooling outdoor air temperature.
• Maximum cooling outdoor air temperature.
