The VAV Zone Controller system consists of an intelligent LCD thermostat, and a remote termination module for mounting onto the VAV/VVT unit. The thermostat has an LCD display with four pushbuttons for setpoint and occupancy override, and contains a variety of configurable VAV/VVT algorithms. Each termination module comes complete with a damper actuator, optional flow sensor and housing.



The DZNT VAV product line is suitable for controlling

nearly all basic VAV, fan powered VAV or VVT

sequences with choices of 3-stage digital reheat, tri-

state with 2nd stage digital reheat, or analog with 2nd

stage digital reheat.

Some of the advanced features include auto heat/cool

changeover, digital time clock or motion sensor input,

timed overrides for occupancy handling, and config

urable reverse acting digital reheat stages.
