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 secondary low 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.
