Using Your Wired Thermostat

Adjusting the Temperature

The temperature displayed is the current set point. You can easily adjust it:

• Press the set point temperature to switch between heating and cooling set points.
• Press Up ⬆️ or Down ⬇️ to manually adjust by 1°F (0.5°C) increments.

Permitted temperature ranges:

• Heating mode: 59°F – 84°F / 15°C - 28°C.
• Cooling mode: 64°F – 86°F / 17°C - 30°C.

Note: In Auto mode, a minimum difference between heating and cooling set points is enforced to prevent setting temperatures within a protection range.

Operation Mode

Select from the Home Screen by pressing the operation mode icon:

• Cool: Starts a cooling cycle when zone demand is for cooling (T Set-Point < T room).
• Heat: Enables heating when zone demand is for heating (T Set-Point > T room).
• Auto: Automatically switches between cool and heat based on global demand.
• Dry: Starts a dehumidification cooling cycle when zone demand is present (Tset-Point < T room). This mode decreases humidity.
• Emergency Heat: Activates Auxiliary Heat for heating in case of system failure. (Visible only if an auxiliary heating device is installed).

User Mode

These modes offer pre-configured settings for different situations:

• Comfort: Default and standard mode.
• Eco: Optimized for energy efficiency.

• On/Off: Turns the zone On/Off. Also indicates operating mode via a color code system: Purple ? (Stop User mode), Red ? (Heating/Emergency heat), Blue ? (Cooling/Dry mode), Green ? (Set-point temperature reached). Solid light means ON; flashing means OFF.
• Temperature Settings: Adjusts the base set point temperature by ± 1°F/0.5°C (default) or ± 2°F/1°C up to ± 6°F/3°C.

Important: After 10 seconds of inactivity, LEDs turn off. The first press shows status (On/Off, Mode, Set point). Subsequent presses adjust On/Off or temperature.

Using Your Wireless Lite Thermostat

Adjusting the Temperature

Use the On/Off button to turn the zone on or off. The button also displays the operation mode via a color code system.

• Purple ?: Stop User mode.
• Red ?: Heating mode/Emergency heat.
• Blue ?: Cooling and Dry mode.
• Green ?: The set-point temperature has been reached.

If the button is solid lit, the thermostat is ON. If flashing, it is OFF. The button remains lit for 10 seconds to show status, then turns off.

Temperature Control: Use the buttons to raise or lower the base set point temperature by ± 1°F/0.5°C (default) or ± 2°F/1°C up to ± 6°F/3°C. LEDs indicate steps above or below the base temperature. Icons flash when the three-step limit is reached.

About the Battery

A battery alert ? appears when the battery of a Wireless Lite Thermostat is low. To replace, remove the thermostat from its back plate and replace the CR2450 battery.
