ZPS - Plenum Supply Air Temperature Sensor
- Technical Documents
The Zoning Plenum Sensor, Model ZPS, is a duct mounted sensor used with the ZONEFIRST MasterZone™ Control Panels. The ZPS senses the supply air plenum temperature and protects the furnace, compressor or heat pump from over temperatureas zone dampers close down and air flow may be restricted and especially when a by-pass is used and supply is mixed back into the return air which can cause extreme plenum temperatures. The ZPS protects the equipment by cutting off the heating or cooling call when its limit temperature is reached for either heating or cooling. The ZPS insures the heating and cooling equipment is protected when zoning.
