Product Features:

The ZIP Economizer is a modular designed, plug and play economizer control solution. The ZIP offers an extended temperature transflective LCD display, with on board help, providing information every step of the way. Through its patented ZIP code set up, the system will automatically recognize your climate zone and will set the high limit change over temperature providing automatic compliance. Integrated onboard test sequence that ensures effortless compliance with California Title 24, and verification of proper operation. Auto-detection of inputted devices and non-proprietary sensors, allows for a quicker, and easier set up. Through its superior fault detection and diagnostics (FDD), it troubleshoots faults, initiates alarms, and reconfigures for best operation. Up to 10 alarms are stored as historic alarms, and with operating hours tracking it makes troubleshooting and maintenance easier.


Direct expansion RTUs up to 30 tons, single dry bulb, single enthalpy, differential dry bulb, differential enthalpy change over strategies. Integrated cooling operations only when damper is 100% open (2 stages thermostat required). When optional energy module is used (ECON-ZIP-EM) demand control ventilation, pre occupancy purge, power exhaust, remote damper position override, fan speed switch. When optional communication module (ECON-ZIP-COM) is used remote alarm indication is available.
