Other Functional Components
This section provides additional information for understanding thermostat operation or programming.
Some of the following sections refer to specific Option Numbers that are listed in
Table 7, p. 25 .
Sleep Mode
Sleep mode places the CPU into a low power state when the thermostat is inactive.
Note: Sleep mode is not implemented, but is noted here for future reference.
Changeover Operation
When the system is set to AUTO Mode , the thermostat automatically selects Cool Mode or Heat Mode
depending on the room temperature and the setpoint temperature. If the changeover setting is set to
manual, then
AUTO Mode cannot be selected when selecting system type and the user would need to
manually change between Cool and Heat Modes. (Refer to 0180)
Changeover Valve Control
The changeover valve control (reversing valve O/B) is used only with heat pump systems. Configuration
Option Number 0153 determines whether the O/B signal is active for cooling or heating (default is O/B
active for cooling).
Extension of Fan-on Time
The system fan-on time is able to be extended for either or both cooling or heating mode. For cooling, the
extension time is 90 seconds and for heating it is 40 seconds (refer to 0270 and 0271).
Economizer/Time of Day (TOD)
You can set the Economizer or TOD mode using Option Number #150 to one of two settings:
•
Economizer Mode - Terminal A is energized with the thermostat in Occupied mode, Unoccupied
mode with a call for cool, or a Temporary Override mode (TOV) active.
• TOD Mode - Terminal A is energized with thermostat in Occupied mode or a Temporary Override mode
(TOV) active.
Note: TOD is not available in non-programming mode.
The table below summarizes the bulleted statements.
Configuration, Time, and Programming Retention
The thermostat retains the time and date for a minimum of 5 days of loss power. If power is lost for more
than 5 days, the time and date will need to be restored when power is returned. All configuration settings,
system settings, and scheduling are stored in non-volatile memory which will retain the data indefinitely
with/without power
