Front Panel Button Operation • System Mode Indication (FCU Only) “Off” on the display means the unit will not provide cooling, heating, dehumidification or fan operation (“E” “Heat/Cool/Auto/Off” terminal goes Low). The “Heat/Cool/Auto/Off” Mode Indicators on the bottom • “Dhum” on the display means that only dehumidification of the display show the mode status of the sensor and are will operate.
The humidity setpoint is always between 40% to 90%. After 5 seconds of no buttons being pushed, the sensor will go into as FCU). 910121754 = Jumper installed for the standard display mode. WSHP (Default for units ordered System Mode Button (FCU Has as WSHP).
