Schedule Setup
Schedules can be used to set the day/time/periods and to set the fan and setpoints.This section
describes the following:
 Schedule display mode
 Day/period/time schedule change mode
 Setpoint/fan schedule change mode
When setting either the day/period/time schedule or setpoint schedule, refer to Table
 8, p. 35for
default settings and worksheet.
Schedule Display Mode
This display mode is used to view current settings such as setpoints, periods, and day of the week as shown in the illustration below. When in Schedule Display Mode, the user cannot change
settings.

Other Thermostat Functions
The programmable thermostat has other functional features which provide more flexibility and
control in its operation. Those features are:
 Heat/Cool indicator display (for both programmable and non-programmable thermostats (refer to
 the next section, “Heat/Cool Indicator Display” )
 Non-programmable mode
 Filter change
 Clean screen
 Local/remote/outdoor temperature display and control
 Local/remote humidity display and control
 System lock
Heat/Cool Indicator Display
Setpoint display: when the system is set for only Heat or only Cool, there is no flame ( ) or
snowflake ( ) icon under the setpoint value.
When the system is set to AUTO( ), the following applies:
 When the thermistor used for H/C control is above the Cool Setpoint, the Cool Setpoint will show
 on the display along with the snowflake ( ) under the setpoint.
 When the thermistor used for H/C control is below the Heat Setpoint, the Heat Setpoint will show
 on the display along with the flame ( ) under the setpoint.
 When the thermistor used for H/C control is between the Cool and Heat Setpoints (inclusive), the
 last active system setpoint (Cool or Heat) will show on the display.
When the system is set to AUTO(
 ), the blink rates for the snowflake ( ) and flame ( )
under the setpoint are as follows:
 When no Cool or Heat cycle is running and no compressor protection timer running, if the Heat Setpoint
 is showing, then the flame ( ) under the setpoint will blink at 4.5 seconds ONand
1.75 seconds OFF.
 When no Cool or Heat cycle is running and no compressor protection timer running, if the Cool Setpoint
 is showing, then the snowflake ( ) under the setpoint will blink at 4.5 seconds ON
and 1.75 seconds OFF.
 When Cool cycle is running, then the snowflake ( ) under setpoint should be solid.
 When Heat cycle is running, then the flame ( ) under setpoint should be solid.
 When the compressor timer is running before Cool cycle, then the snowflake ( ) under
setpoint should blink 1.5 seconds ONand
 0.5 secondOFF.
 When the compressor timer is running before Heat cycle, then the flame ( ) under setpoint
should blink 1.5 seconds ONand
 0.5 secondOFF.

Non-programmable Mode
The thermostat is capable of being configured as non-programmable (refer to Configuration
Option Number 0140 in Table 7, p. 24). If the thermostat is set to non-programmable mode, certain
icons are not displayed and scheduling and override functionality is not available. The Home
screens will similarly display as shown below.
Non-programmable Functionality
 Scheduling and Override modes are not available.
 The following features are not displayed; occupied ( ), unoccupied (), period schedules
(
).
 Fan can be set to either AUTOorON.
 Setpoints are changed directly by touching the setpoint Up/Down arrows. If the system is set toAUTO ,

then the user can toggle between Cool and Heat setpoints with the snowflake icon
( ) and the flame icon ( ).
 All other Non-programmable
 Modefunctionality is the same as in Programmable Mode,
such as System Mode Setup, Fan Mode, Humidity Setup, or Clock .

Filter Change
Filter change indicates when the system change filter timer is expired. The filter icon ( ) will blink
continuously 1.5 secondsONand 0.5 secondsOFFon theHomescreen (orTOV Activescreen)
until this feature is reset. To reset the filter change indicator, press and hold both left and right
arrows at the same time for 3 seconds (refer to the illustration below).
The default setting for filter replacement is one (1) month. To change this duration, refer to
Configuration Option Number 0275 inTable 7, p. 24.
Clean Screen
TheClean Screenfeature allows the user to clean the LCD screen by deactivating the touch screen
without affecting any current settings. From theHomescreen, touch the clean screen icon ( ).
The LCD screen becomes inactive and only shows a 30-second countdown (shown below on the
right) before returning to theHomeorTOV Activescreen. Clean the screen with a non-abrasive
cloth and a mild ammonia-free cleaning solution.

Local/Remote/Outdoor Temperature Display and Control
The thermostat has the capability of displaying the local indoor temperature and/or the remote
indoor/outdoor temperatures, depending on the value setting for Configuration Option Number
0210. There are two terminals to connect the remote sensor,S1andS2. The table that follows
provides information about displaying either local, remote, or outdoor temperatures and how
temperatures are controlled (refer to Configuration Option Number 0210 inTable 7, p. 24).
Option 
Number 0210Installer Parameter Number Value Description
0
Uses the internal/local sensor for Cool and Heat control. Displays only local indoor temperature.
1Uses the internal/local sensor for Cool and Heat control. Displays both indoor local and remote 
temperatures. Remote sensor typically placed outdoors.(a)
(a) Remote sensor can be placed indoor or outdoor depending on the application.
2
Uses internal/local sensor for Cool and Heat control. Uses remote S1/S2 thermistor for compressor/
auxiliary heat lockout feature. Displays both indoor and outdoor temperatures. Remote sensor is typically 
placed outdoors near compressor equipment.
(a) (See Option numbers 0220/0221 and the section, 
“Compressor and Auxiliary Heat Lockout,” p. 47, for more details.)
3Uses S1/S2 thermistor for Cool and Heat control. The internal thermistor is disabled. Displays only the 
remote indoor temperature and is displayed in the location normally reserved for the local thermistor. 
Remote sensor is typically placed indoors where H/C control is desired.
(a)
4
Uses the average temperature of the local sensor and the remote S1/S2 sensor for Cool and Heat control. 
No secondary temperature displayed. If either temperature is outside the measuring range, an error code 
will display.
(b) The average temperature is displayed in the location normally reserved for the local 
thermistor. Remote sensor is typically placed indoors away from the thermostat to allow temperature 
averaging from one side of a room to the other.
(a)
(b) If an out-of-range error occurs on either the local or remote thermistor (but not both), then the firmware will use the 
good thermistor reading without averaging to control Cool or Heat cycles. If or when the bad thermistor returns to a good 
state, then the firmware will return to using both thermistors and average the two values.
