Note: The user can manually reset the thermostat to all default settings by changing Configuration
Option Number 0300 to 1.
Heat/Cool Relay Confirmation
As a guard against inadvertent relay switching, the thermostat firmware will set/reset the output relays
every half hour if the relationship of setpoint versus temperature is out of range as follows:
•
Auto systems with cool/heat setpoints: temperature is 5°F (2.5°C) above the cool setpoint or 5°F
(2.5°C) below the heat setpoint
• Only heat systems: temperature is above or below the heat setpoint by 5°F (2.5°C)
• Only cool systems: temperature is above or below the cool setpoint by 5°F (2.5°C)
Deadband
The thermostat automatically maintains a temperature deadband between the heating setpoint and the
cooling setpoint whenever the thermostat is configured for heat and cool– this applies to Auto or manual
H/C setup. The temperature range of the deadband is 2°F to 9°F (1.0°C to 4.5°C) and is specified in the
installation Configuration Option 0181 (see
“Configuration Option Setup,” p. 24 ). If attempting to change
a temperature setpoint to within the deadband of its opposing setpoint, the opposing setpoint will
automatically be pushed to the next value that satisfies the deadband.
Temperature Display Offset
The offset parameter applies only to the Local Temperature Display (when Configuration Option Number
0210 is set to 0, 1, or 2) or to the Indoor Remote Temperature Display (when Configuration Option
Number 0210 is set to 3). It does not apply to the Outdoor Remote Temperature Display (when
Configuration Option Number 0210 is set to either 1 or 2). The offset range is -3°F to 3°F (-1.5°C to 1.5°C)
[Refer to 0210 and 0260]. When Configuration Option Number 0210 is set to 4, the offset will apply after
the average temperature is calculated from both the internal and remote temperature sensor. If one sensor
goes bad, then the offset will apply to the remaining good temperature sensor reading.
Humidity Display Offset
Humidity offset allows adjustment of the humidity reading in the field. The offset range is -9% to 9%. There
is a separate humidity offset for the internal and external humidity sensor. (Refer to 0206, 0207)
LCD Backlight
With Configuration Option Number 0170 set to 0 for Non-continuous Backlight, the backlight will turn ON
if any touch areas of the display screen are touched and turn OFF after a timer expires.
Note: When Configuration Option Number 0170 is set to 1, the backlight is ON continuously with no time
outs.
Typical expiration times are:
•
15 seconds from Home screen non-functional area touches (typically 20 seconds for a functional area
touch plus an extra 15 seconds after returning to Home or TOV Active screens).
• 60 seconds when in Schedule Change Mode, plus and extra 15 seconds after exiting.
• 30 seconds in Clean Screen Mode plus an extra 15 seconds after returning to Home or TOV Active
screens.
• Backlight on during Power Up sequence plus an extra 15 seconds after arriving at the Home screen.
• ON continuously in Configuration and Test Modes .
