Sensi™ Wi-Fi Programmable Thermostat Installation Guide 13 Installer Information

WARNING

On two transformer systems, the transformers MUST be in phase. Measure the voltage across RC and RH. If more than 12 Volts AC is present between RC and RH, then the transformers are NOT in phase.To correct this condition, reverse the secondarylow voltage connections at either the Heating or Cooling transformer.

Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code. Do not use on circuits exceeding specified voltage.

WARNING

Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard.

CAUTION

To prevent electrical shock and/or equipment damage, disconnect electric power to system at maincircuit breaker box until installation is complete.If “Call For Service” is displayed on your Sensi thermostat, and E4 or E5 appears where the room temperature should be displayed or the backlight is flashing, please call our support team immediately at 888.605.7131.
