•Energy Management System Features

Temperature Setback - This option can save energy dollars for unrented or unoccupied rooms by automatically setting back the operational temperatures. This mode of operation is selected through the configuration routine (see Configu- ration Settings section). If none of the keys on the control pad have been pressed for an 18-hour period. The unit will automatically go into a 3-stage setback routine; after 30 minutes, a 1 degrees setback; after 3 hours, 3 degrees, and at 8 hours, a 7-degree setback. NOTE: Temperature set- back does not work with a wired remote thermostat .

Door Switch and Motion Sensor Low Voltage Terminals (DS1, DS2, MS1, MS2) - The door switch and motion sen- sor operate as a unit, the door switch terminals allows for wired connection of a door sensor to the control board. The motion sensor interprets any door movement as a signal of occupancy. If the switch between DS1 and DS2 is closed, the door control will interpret the room door as closed. If the switch between MS1 and MS2 terminals is opened (or closed if unit is configured for normally open) the control will interpret the action as a signal of occupancy. If thirty min- utes pass without any door activity, Energy Management Temperature setback activates.

Serial Port Interfaces - Two serial ports located on the con- trol board provide easy access for two-way communications to the control board from handheld PDA devices. An op- tional RF antennae can be attached for wireless communi- cations.
