ATC32U01A Communicating, Programmable Thermostat - IOM
Created: 1 Oct., 2012
5.0 Input Dealer Information
Enter/edit the Dealer Information settings, including Brand
Name, Model Number, Serial Number, Contractor Name, and
Contractor Phone number, using the up/down arrow buttons.
Press the center button to save changes.
Adjust the Air Cleaner Reminder settings using the up/down
arrow buttons. Press the center button to save changes.
• Cumulative Run Time (default Off) – valid range:
Off, 400 to 3600 hours (in 100 hour increments)
• Calendar Time (default Off) – valid range: Off, 3
to 24 months (in 3 month increments)
6.0 Humidity Confi guration
Confi gure humidity control settings (dehumidifi cation/
humidifi cation).
Adjust the Humidity Control settings using the up/down arrow
buttons. Press the center button to save changes.
• Dehumidifi cation – This logic will communicate
a Dehumidifi cation output when the humidity is
greater than the setpoint (acts as a dehumidistat).
The Dehumidifi cation output will not be
communicated when the humidity is below the
setpoint.
• Humidifi cation – This logic will communicate a
Humidifi cation output when the humidity is less
than the setpoint (acts as a humidistat). When the
Humidifi cation output is active, the fan output will
also be active. The Humidifi cation output will not
be communicated when the humidity is above the
setpoint.
• Both – Incorporates both Dehumidifi cation and
Humidifi cation logic.
• None (default) – Dehumidifi cation
and Humidifi cation outputs will not be
communicated.
7.0 Temperature Algorithm
Confi gure the logic the thermostat uses to meet the
temperature setpoints.
• Proportional Integral (default) – This logic will
use a combination of temperature differential and
operating time to determine the appropriate heating
or cooling stages for operation (see NOTE 1).
• Proportional Integral (No Down Staging) – This
logic includes the Proportional Integral logic, but
in addition the logic keeps all active heating or
cooling stages energized until the demand is fully
satisfi ed (see NOTE 1).
• Differential – This logic will only use temperature
differential to determine the appropriate heating or
cooling stages for operation. This logic will keep
all active heating or cooling stages energized until
the demand is fully satisfi ed (see NOTE 2).
NOTE 1: The Proportional Integral options require fi rst stage
heating or cooling to be active for a minimum of 5 minutes,
before energizing second stage when confi gured for multi
stage operation.
NOTE 2: The Differential option will activate fi rst stage heating
or cooling when the temperature is more than the fi rst stage
differential value (User Manual section 5.6.2.3), below or
above the setpoint. Second stage heating or cooling will be
activated when the temperature is more than the fi rst and
second stage differential values combined (User Manual
section 5.6.2.3), below or above the setpoint. Third stage
heating will be activated when the temperature is more than
the fi rst, second, and third stage differential values combined
(User Manual section 5.6.2.3), below the setpoint.
8.0 Demand Reduction
Confi guration
Demand Reduction is activated by an input signal at the unit
control board to reduce the electric load while peak utility
rates are high. The Demand Reduction Confi guration mode
selects which of the available unit control inputs is to be
used as the activation signal. While a physical input signal is
present at the selected input, the thermostat will implement
load reduction by limiting operation or capacity. Refer to
section 5.6.9 in the user manual (part number ???) for more
details on Demand Reduction.
Adjust the Demand Reduction Confi guration setting using
the up/down arrow buttons. Press the center button to save
changes.
• No Demand Reduction (default) – Demand
Reduction operating mode will not be activated by
a DXM2 input.
• DXM2 Inputs – Assigns a DXM2 input to activate
Demand Reduction operating mode.
