ECONOMY CYCLE CONTROLS ONLY with O/A & R/A TEMP / CO2 DUCT SENSOR

Description

ENDEAVOUR PRESET WITH ONLY ECONOMY CYCLE INPUTS & OUTPUTS

Controller used for FREE COOLING economy cycle control & CO2 control only, typically because the A/C unit comes complete with a room temperature /time switch control station (so called pendent) but not also capable of controlling economy cycle & CO2 operation, adding this system adds those functions. Operation is if the return air temperature is above the controllers setpoint (ie 23c) and the outside air temperature is measured to be cooler then fresh air, economy cycle mode is instigated and will modulate the dampers over one degree rise from the setpoint to the fresh air mode. Plus based on return air CO2 only, if the measured CO2 level is above the pre-set CO2 setpoint ..ie 600ppm, the economy cycle dampers will also modulate open to fresh mode to lower the CO2 levels regardless of temperatures ….although limits for low & high extreme temperatures can also be set to restrict CO2 damper control use.. All settings are site adjustable.
