In a basic Economizer System, either an outdoor temp (C7650) or an enthalpy sensor (C7400) will be needed. For mixed or discharge air, the C7046 or the C7150 can be used. In cases where DCV is used, either the C7232 or The C7632 CO2 Sensors can be used.
Digital enthalpy (humidity/temperature) sensor for use with S-Bus devices and W7220 economizer controller
Analog outdoor and Mixed air temperature sensor – 20k ohm NTC for use with W7220 economizer controller
Analog enthalpy sensor for use with W7212 and W7459 economizer controllers
Selectable outdoor temperature sensor for use with W7212 and W7459 economizers for referential dry bulb changeover.
Analog humidity sensor for 5% over range of 10-90% RH. Only works with W7340
C7150 Solid State mixed air sensor is used with Honeywell economizer logic modules and W973 and M7415 to proportion outdoor and return air dampers in economizer systems.
