APPENDIX A - SETTINGS
42
1
System Type
The thermostat can be adapted for many uses. However, operation of the Acadia requires the HP2 setting.
2
Indoor Fan
Controlled By
The thermostat can control the indoor fan if necessary. The Acadia requires the thermostat to energize the indoor fan
for ELE. GAS is used with a fossil fuel system where the fan needs to be controlled by the heat source.
3
Programming
This thermostat can be setup to run a program for each day of the week, a 5-day block with separate weekend
parameters, or a 0-day block to disable programming. For most efficient operation, 0-day block is recommended.
4
Program Set Points
This thermostat can be programmed with 2 or 4 set points during the day if there is a program. If using 0-day block, or
no programming, this setting is not applicable.
5
System Switch
Configuration
This control can be setup to run in Cool mode, Off, Heat mode, Emergency Heating mode, and Cool and Heat Auto
Changeover.
6
Energy
Management
Recovery
This control can make use of Energy Management Recovery (E) strategies, in which the system will be brought online
early to ensure the program set point is reached at the specified time. Heating will start 5 minutes early for every 1°F
required to reach the set point. This setting is not applicable with 0-day programming.
7,8,9
Cycle Rate
Selection
Slow cycles heat at 1.2 °F, cool mode cycles at 1.7°F. Hallowell recommends, SL - Slow cycle; this setting is to optimize
the system efficiency by minimizing system cycling. If a faster recovery rate is desired (heat - 0.6°F, cool - 1.2°F) select
FA. Choosing FA will yield a reduction in efficiency and increased system cycling. EMER is left in FA, as a delay is not
necessary.
10
Compressor
Lockout
This thermostat has a built in 5 minute delay between cycles. This lockout should be ON to help prevent compressor
short-cycling.
11
Display Backlight
When this option is turned ON, the display backlight will remain illuminated continuously. When this option is turned
OFF, the display backlight will illuminate briefly after any key is pressed, then return to OFF after 5 seconds.
12
Temperature
Display Adjustment
This option is used to adjust the displayed temperature to match the previous thermostat. The range of adjustment is
4° higher or lower.
13
Degree Readout
This is to select the desired temperature readout; Fahrenheit (F) or Celsius (C).
14
Beeper On/Off
Turn the key beeper ON or OFF with this setting.
15
Heat Temperature
Limit
This is the highest allowable temperature for the heating mode. The allowable range for the Acadia is 65°F to 80°F.
When this is active, the “temperature limit” icon is displayed to the left of the set point temperature. If an attempt is
made to adjust the set point above the limit, the “temperature limit” icon will flash.
16
Cool Temperature
Limit
This is the lowest allowable temperature for the cooling mode. The allowable range for the Acadia is 65°F to 80°F.
When this is active, the “temperature limit” icon is displayed to the left of the set point temperature. If an attempt is
made to adjust the set point below the limit, the “temperature limit” icon will flash.
17
Keypad Lockout
The keypad lockout is available to prevent undesired temperature and mode changes. This is a three stage lockout,
consisting of:

Keypad Lockout and L: Total lockout, preventing temperature and/or mode changes.

Keypad Lockout and P: Partial lockout, allowing temperature changes within the set temperature limits.

Temperature Limit/Keypad Lockout: Prevention of changing the set temperature limits.
18
Keypad Lockout
Combination
This menu item is used to select the 3 digit key-code to disable the keypad lockout, and to turn the lockout On/Off.
Use the

and

keys to select the keypad lockout combination (000 is not a valid lockout combination). When
finished, press ↑to exit the menu. The system mode key will remain active for 10 seconds allowing a mode change.
19,20
Fast Second Stage
This should be set to FA Heat/FA Cool ON. When in run mode with the Fast Heat (FA Heat ON) enabled and the heat
set point is manually raised by 3°F or more above the space temperature, the 2
nd
and 3
rd
stage energize immediately.
If FA Heat is OFF, the 2
nd
stage will not energize until the set point is 1°F or more above the space temperature for 10
minutes. For FA Cool, the operation is the same concept, only for cooling operation.
21
Filter Reminder
This provides a reminder to change the air handler filter based on indoor fan runtime. Change Filter display can be
cleared by pressing the Clean Display when Change Filter is on the screen.
22
Filter Replacement
Run Time
This should be set to 725 hours (one month), unless otherwise recommended.
23
Humidifier Pad
Replacement Run
Time
This provides a reminder to change the humidifier pad (if so equipped), based on heating mode run time.
