The W7340 is used with both solid state temperature and humidity or enthalpy sensors. The W7345 is used with solid state temperature sensors only. FEATURES • Solid state control package provides accuracy, reliability and stability. • Housed in high-impact, glass-fiber reinforced plastic case. • Terminals included for connecting optional S963B1136Remote Potentiometer for remote minimum damper position control. • Communicates using a modified Modbus protocol. • Case matches the lines of the M7215 Damper Motor. • LED indicates the status of the device input. W7340 Only • Operates from the Modbus input, environmental sensors, and a DCV sensor to provide a totallyintegrated control system. • Combines minimum damper position potentiometerwith solid state temperature (10K NTC) and humidity orenthalpy changeover control to provide economizer free cooling function; this control can be overriddenby input via Modbus or DCV sensor. W7345 Only • Operates from the Modbus input and mixed/discharge air sensor to provide a temperature control system. • Combines the Modbus indoor and/or outdoor temperature input with the mixed air input to provideeconomizer dry bulb free cooling function.

W7345: Communicating Economizer Logic Module with minimum position potentiometer and setpoint for dry-bulb temperature only. IMPORTANT W7340A, W7340B and W7345A: 1. Do not have the ability to set DCV minimum position for damper position for demand control ventilation. Damper may drive 100% open on call from CO2 sensor. 2. Do not have the E (enthalpy or dry bulb) curve setting. 3. W7340C has the ability to set DCV minimum position and has the E curve setting. Dimensions: See Fig. 1.
