Pressure Independent Zone Controller

Features

• Pressure independent operation
• Control supplemental heat
• Series/parallel fan powered mixing box operation
• Zone IAQ capability

The Pressure Independent Zone Controller is a component of the VVT HVAC Controls system and is used in applications where zone independent operation is required. The 33CSZC--PI must be used with either the 33CSPS--01 or 33CSPS--02 pressure sensor (depends on the pressure range, see specs for the pressure sensor) to control either CFMs or static pressure. The zone controller can be used to control supplemental heat as well as series/parallel fan powered mixing boxes.

The Zone Controller allows each occupant to control the temperature comfort within their spaces. It continously monitors zone temperature conditions, zone demand, overrides, diagnostic information and communicates it to the VVT Monitor Thermostat.
