Terminals S1 and S2 can be used for an indoor remote sensor.

The indoor remote sensor is used to read the indoor temperature

in a different location. This is benecial when the thermostat is not

mounted in the ideal location.

1. Remove cover from remote sensor housing.

2. Select an appropriate location for mounting the remote sensor.

3. Mount remote sensor unit using hardware provided.

4. Install two strand shielded wire between remote sensor and

thermostat. Shielded wire is recommended.

Do not run remote sensor wire in conduit with other wires.

• Wire 1 should run between the S1 terminal on the thermostat

and the S1 terminal on the remote sensor

• Wire 2 should run between the S2 terminal on the thermostat

and the S2 terminal on the remote sensor

• Connect the shielding of the wire to the S2 terminal on the thermostat

5. Congure the thermostat to operate with the remote indoor sensor (see Conguration Mode setting 13).

The Amana 2246008 is a programmable electronic thermostat designed for efficient control of heating and cooling systems in residential and light commercial settings. This device supports 2-stage heat and 2-stage cool systems, including heat pumps, and is compatible with gas, oil, or electric heating. Its primary function is to maintain a desired indoor temperature according to user-defined schedules, offering flexibility and energy savings.

Function Description

The thermostat operates by sensing the ambient room temperature and comparing it to the user-set temperature (setpoint). When the room temperature deviates from the setpoint, the thermostat activates the appropriate heating or cooling stage to bring the temperature back to the desired level. It features auto changeover, allowing it to automatically switch between heating and cooling modes as needed, based on the setpoints for both. The device also includes an anti-short cycle delay to protect the compressor from rapid cycling, thus extending its lifespan.

The Amana 2246008 is highly configurable to match various HVAC system types. Users can select between Fahrenheit or Celsius temperature scales and adjust settings for different heat pump configurations (one or two compressors, with or without electric backup), as well as conventional heat/cool systems. The thermostat provides relay outputs for controlling the fan, first and second stages of heating, and first and second stages of cooling.

An optional indoor remote sensor can be connected to the thermostat to measure temperature in a different location, which is useful if the thermostat itself is not in an ideal spot for accurate temperature readings. The thermostat can also display the outdoor temperature if an optional outdoor sensor is installed.

Usage Features

The Amana 2246008 offers a user-friendly interface with a large display and backlight for easy readability, even in low light conditions. The display shows the current room temperature, setpoint, system mode (Heat, Cool, Auto, Off), fan mode (Auto, On), and various icons indicating active functions like lock mode, outdoor sensor activation, and temperature offset.

Programming and Scheduling:

The thermostat supports flexible programming options:

7-Day Programming: Allows for a unique schedule for each day of the week.
5-2-Day Programming: Provides one schedule for weekdays (Monday-Friday) and another for weekends (Saturday-Sunday).
5-1-1-Day Programming: Offers one schedule for weekdays, and separate schedules for Saturday and Sunday.

Users can set up to four periods per day (Wake, Leave, Return, Sleep) with different temperature setpoints for each period, optimizing comfort and energy use throughout the day. The programming is intuitive, guided by on-screen prompts and button controls.

System Modes:

OFF Mode: Turns off all heating and cooling functions. The fan can still be operated manually.
HEAT Mode: Activates only the heating system. The thermostat will maintain the heat setpoint.
COOL Mode: Activates only the cooling system. The thermostat will maintain the cool setpoint.
AUTO Mode: Automatically switches between heating and cooling to maintain both heat and cool setpoints within a defined deadband. This mode is ideal for climates with fluctuating temperatures.

Fan Modes:

AUTO Fan: The fan runs only when the heating or cooling system is actively operating.
ON Fan: The fan runs continuously, regardless of whether the heating or cooling system is active.

Configuration Mode:

The configuration mode allows users to customize various operational parameters to suit their specific system and preferences. Key settings include:

Temperature Scale: Fahrenheit or Celsius.
Temperature Differential: Adjusts the temperature difference between the setpoint and when the system turns on (1st stage) and between the 1st and 2nd stages.
Staged Off Outputs: Determines if heating/cooling outputs turn off independently or simultaneously.
Minimum Deadband: Sets the minimum temperature separation between heat and cool setpoints in Auto mode.
System Type: Configures for heat pump (with O or B reversing valve, 1 or 2 compressors) or non-heat pump (gas/electric).
Auxiliary Delay ON: Sets a delay for auxiliary heat to engage after a call for 2nd stage heat, allowing the heat pump to try and satisfy the call first.
Lockout: Allows for keypad lockout to prevent unauthorized changes to settings, with options to limit setpoint adjustment or lock out during NITE periods.
Maximum Heat Setpoint/Minimum Cool Setpoint: Defines the allowable range for temperature setpoints.
Room Temperature Offset: Calibrates the displayed room temperature to match the actual room temperature.
Maximum Cycles Allowed Per Hour: Limits the number of times the system can cycle on/off within an hour to protect equipment.
Temperature Sensor: Selects whether to use the on-board sensor, remote sensor, an average of both, or switch between them during NITE periods.
Cooling Fan Delay Off Time: Sets a fan purge time after the cooling cycle ends.

Maintenance Features

The Amana 2246008 is designed for minimal maintenance. Regular cleaning of the thermostat cover is recommended to ensure proper sensor operation. The device includes a reset switch that can be used to restore factory default settings if needed, which can be helpful for troubleshooting or reconfiguring the thermostat.

The thermostat is designed for easy installation, with clear wiring diagrams provided for various system configurations. The terminal designators are clearly labeled, simplifying the connection process. For optimal performance, it is important to follow the installation guidelines, such as mounting the thermostat in an appropriate location away from direct sunlight, drafts, or heat sources.

In case of operational issues, the manual provides a troubleshooting guide that lists common problems and their corresponding remedies, such as checking power, wiring connections, and configuration settings. The device's robust design and configurable features contribute to its long-term reliability and ease of use.
