ENTERING EMERGENCY HEAT MODE (HP UNITS ONLY)
• While in HEAT mode, press DOWN + MODE for 5 seconds. The thermostat will show HEAT with “E” to conrm Emergency
Heat mode. This will use only the W2 wire as the heating source and will not call for compressor heating.
• To return to normal heating mode, set thermostat to HEAT mode, press and hold BOTH the MODE and DOWN buttons for at
least 5 seconds until the screen changes. The “E” will disappear and only show “HEAT” to conrm regular Heat mode.
