[. . . ] The EEPROM device has a maximum 10, 000 allowable number of writes. This means that these parameters should not be written to frequently by another controller that is calculating values every few seconds and sending these values to an Excel 10 VAV Controller. IMPORTANT Excel 10 VAV Controllers are not capable of controlling both a staged type reheat device and a modulating reheat device in the same VAV box. The W7751H Smart VAV Actuator is a physically smaller controller in the Excel 10 family product line. It has a factory-mounted ML6161B1000 Actuator and was designed for basic VAV box control applications. It has all of the control and communications functionality of the W7751B, D, F Controllers with the exception of the following. Physical digital inputs for window open/closed or an occupancy sensor or physical outputs for stage three reheat. It also does not contain a network access communications jack or a selftest input.

(10 to 35°C) Space Temperature Setpoint to be maintained during STANDBY while 50 to 95°F in COOL mode operation. This value is also used to provide an upper (10 to 35°C) limit on the user adjustable remote setpoint pot (wall module). Space Temperature Setpoint to be maintained during UNOCC while in 50 to 95°F COOL mode operation. (10 to 35°C) Space Temperature Setpoint to be maintained during OCC time while 50 to 95°F in HEAT/REHEAT mode operation. (10 to 35°C) Space Temperature Setpoint to be maintained during STANDBY while 50 to 95°F in HEAT/REHEAT mode operation. This value is also used to provide (10 to 35°C) a lower limit on the user adjustable remote setpoint pot (wall module) minus Deadband (E-Vision Application selection). Space Temperature Setpoint to be maintained during UNOCC while in 50 to 95°F HEAT/REHEAT mode operation.
