Actuator Travel Time – Sets how
many seconds it takes to rotate the
damper from full closed to full
open.
Floating Damper Configurations:
Ventilation Damper Position –
Sets the position to rotate the
damper to during ventilation
cycles.
Maximum Damper Position – Set
the position to rotate the damper
to during heating, cooling, and
reheat cycles.
Damper Signal Output – Sets
which analog output is used for
damper modulation.

Damper Actuator Voltages – Sets
the volt [DC] range for the
modulating damper.
¹For mixing box applications, this will be labeled “Cold” which will
be the output voltage to rotate towards the cold deck.
²For mixing box applications, this will be labeled “Heat” which will
be the output voltage to rotate towards the hot deck.
³Modulating Damper Configurations will automatically appear only
if a PEARL is wired to the thermostat and if the Damper Type is set
to one of the modulating options.
Configurations
Economizer (turn OFF)
When a PEARL is connected to a thermostat, this
configuration option appears. Make sure to turn OFF the
economizer sequences, as they are not used in damper
control operations.

Cool Fan Speed – Sets the fan
speed during moderate cooling
cycles.

speed during aggressive heating
cycles.
Configuration Name/Description
Heat Size – Sets the energy
consumption when the moderate
heating is enabled.
Heat 2 Size –Sets the energy
consumption when the aggressive
heating is enabled.
Cool Size – Sets the energy
consumption when the moderate
cooling is enabled.
Cool 2 Size – Sets the energy

Power Consumption
Provides settings for the consumption of different
demand states.
BTU - British Thermal Units - most common for gas
furnaces and hot water.
TON - Tonnage - most common for compressor stages
and chilled water.
KW - Kilowatt - most accurate if true kilowatt
consumption is known for each stage.
WATT - Watt - most accurate if true watt of consumption
is known for each stage.
Variable Speed Fan
When a PEARL is connected to a thermostat, this option
appears. It is rarely used in damper control but can
control a modulating fan terminal box. The PEARL's (A2)
output regulates fan speed, ranging from 0.0 VDC (0%)
to 10.0 VDC (100%)
