•
Cool Mode Indicator - The Cool Mode LED lights when the cool-only mode is selected or when the unit is in an
Automatic Mode cooling cycle.
•
Heat Mode Indicator - The Heat Mode LED lights when the heat-only mode is selected or when the unit is in an

by activating the Heat Mode or Cool Mode indicator when either mode is called for while in the Automatic Mode. No
water-valve status is indicated when in manual Heat or Cool Modes. If the control is programmed for electric heat, then
the indicator will light up if either the valve or the heater are energized.
•
Digital Display - The 3-digit, 7-segment digital display shows inside air temperature when the control is on. It displays
the set point when either the Up or Down button is pressed. The display also indicates program information and fault
codes. When the control resumes operation after a power interruption, "888" appears in the display and all the LEDs
light for one second. This is normal Power-On Reset operation.
