The Lennox Y7766 LZP-Two Zone Control Panel is equipment that is used in controlling the temperature in two different zones of a building’s HVAC system. This unit communicates electronically with a compatible single-stage Lennox furnace or air handler and single-stage air conditioner; multi-stage equipment can be used if they contain internal controls for staging. Using zone thermostats and dampers can allow for the control of the temperature of each zone separately. This brings about more comfort since particular zones will have assumed the required levels, and may also lead to energy savings if the occupied zones are only heated or cooled.
