The keyboard is located behind the thermostat cover. Sixteen keys are used to set, review and modify programmed times and temperature settings.
The thermostat display shows a day, time, program period, and temperature.
The thermostat can be set for two Occupied and two Unoccupied times for each day of the week (28 independent time settings). Temporary Occupied key provides quick temporary temperature changes for increased occupant comfort. The Continuous An unoccupied key provides energy-efficient operation for extended periods of time.
Before starting the program procedure, use the the following chart to organize the program schedule.
Day | Occupied Period 1 | Unoccupied Period 1 | Occupied Period 2 | Unoccupied Period 2 |
Monday | ||||
Tuesday | ||||
Wednesday | ||||
Thursday | ||||
Friday | ||||
Saturday | ||||
Sunday |
The program has four temperature settings, Occupied and Unoccupied heat, and cool. The thermostat will operate at the Unoccupied temperature setting unless the thermostat is programmed. The following chart shows the default temperature settings.
Control | Occupied Setpoint | Unoccupied Setpoint | ||
Default | Desired | Default | Desired | |
Heating | 70°F (21°C) | 55°F (13°C) | ||
Cooling | 78°F (25.5°C) | 90°F (32°C) |
NOTE: The thermostat must be in program mode to use the copy feature. Go to step 2 if the thermostat is already in the program mode.
NOTE: The setpoint temperature range is 40 to 90°F (7 to 31°C) for heating and 45 to 99°F (9 to 37°C) for cooling.
