BAS-SVX44A-EN29 Functions System Mode Setup Note:If unable to change the system mode to a desired setting, check the system type setting and the manual/auto-changeover setting (refer to the section, “Configuration Option Setup,” p. 23) to verify how the thermostat is configured with heat and cool modes, and that it permits manually changing them. (Refer to Configuration Option Numbers 0130 and 0180). Depending upon the model and system type, the thermostat can be set to one of five modes: Cooling, Heating,Emergency Heat,AUTO ,orOFF . Note: All system icons may not be available– this is configuration setup dependent. To set the system mode: 1. Touch area to activate theSystem Mode Setup. All system mode settings available are visible with the current system setting blinking. Each touch in the system selection box will step to the next available setting as shown below. 2. Choose a system mode and then either touch or a 20-second time out will save the system mode setting and return to the Homescreen. Note: Touching another active area on the display screen (such as clean screen, clock, humidity, or schedule) will also save the system mode setting selected in Step 2 and activate the newly selected system setting. Touching Cancel() will exit system mode setup without saving any changes . Fan Mode Note: The fan is only displayed on systems configured with the fan enabled. If disabled, then the fan icon on the LCD screen is not visible. The Fan mode is typically configured in Schedule Setup. Fan mode changes from the Home screen initiates an override (TOV) [refer to the section, “Schedule Setup,” p. 31]. There are two fan modes. Each are indicated by an icon on the display: To enter fan mode: 1. Touch area to activate the Fan Display Modeand the active fan mode will blink. Note: Touching ,, another active area, or a 20-second time out will return to the Home screen without making changes to the fan.

Refer to the next section, Temporary Override (TOV) Setupto set overrides or touch to cancel and return to the Homescreen. Temporary Override (TOV) Setup TOV allows the user to temporarily override the scheduled temperature setpoint and/or fan settings. There are two ways to enter TOV Mode from the Home screen: Quick TOV : Touch the Occ ( ) or Unocc () icon from the Home screen. A TOV session will start up using the last occupied schedule setpoint settings, the last occupied fan setting, and the default TOV time period (Option Number 0230). Touch OKor wait for a 20-second time out to put the thermostat into quick TOV Active Mode;OR User Configurable TOV : Touch either the Up or Down arrow to blink the setpointfor 20 seconds. Touch of the Up or Down arrows within 20 seconds to change the setpoint and put the thermostat into TOV Setpoint Change Mode; OR Touch the Fan to blink the present Fan setting for 20 seconds. Touch the Fan area within 20 seconds to change the Fan setting and put the thermostat into TOV Setpoint Change Mode. In TOV Setpoint Change Mode , further adjustments can be made to the setpoint or Fan mode with the Up, Down, or Fan areas. Note: For Auto H/C systems, use the cool mode icon ( ) or the heat mode icon () to toggle between cool and heat setpoints respectively. To adjust the TOV time period: Touch the clock icon ( ) to enter TOV Time Setup Mode. The left/right arrow ( or ) will toggle between Days/Hours and the middle Up/Down arrows ( or ) will increment or decrement the time. Note: A second touch of the clock icon ( ) will put the thermostat intoHold Mode which holds the TOV settings indefinitely until canceled by the user. Additional touches of the clock icon ( ) will toggle the thermostat between DAYS/HOURS and Hold . Toggle back to readjust the setpoint(s) by touching the thermometer icon ( ). Touch area to activate the desired settings. Active TOV is indicated by a solid non-blinking hourglass ( ). Note: Desired settings are also activated after a 20-second time out.
