No Common Wire Needed.
Read instructions carefully before attempting to install, operate or service the Lightstat
electronic setback thermostat. Failure to comply with instructions could result in personal
injury and/or property damage. Retain instructions for future reference.
Description
The Lightstat thermostat saves energy and
operating costs by using Owner specified factory
limited temperature ranges which prevent excessive
use of heating or cooling equipment. These limits
cannot be changed by the user. The unit requires no
batteries and no programming or reset in the event of
a power failure. Optionally, the Lightstat thermostat
can set back the temperature based on light level in
the space. A dark space is considered unoccupied
and will turn the heating and cooling setpoints back
for better savings.
Thermostats described are available in Heat/Cool
(TGHC) and Heat Pump (TGHP) models.
