SETUP: SYSTEM PERF Screen
Use the Heat Anticipator to control the steady-state regulation band size. A lower setting
results in more frequent cycles and faster response; a high setting results in less frequent
cycles and a slower response.
Use the Fan Cool Down Time option to control how long the fan will run after a heating call
is finished.
SETUP: DEVICE OPTS Screen
The Network ID must match the NET ID specified in the system program. Use the LCD
Contrast to change the contrast of the LCD screen.
The device name, current firmware version, and identification number are listed at the
bottom of the screen.
BOOKED TIMEOUT Screen
The BOOKED TIMEOUT setting determines how long the room must be empty before
entering the vacant state. Room emptiness is recorded when the passive infrared sensor
does not detect motion. The vacancy state is defined in the control system program.
The BOOKED TIMEOUT setting functions exactly the same as the UNBOOKED TIMEOUT
setting. BOOKED TIMEOUT should be used in a room that is occupied regularly, such as in a
booked hotel room. BOOKED TIMEOUT should be set for a longer period of time than
UNBOOKED TIMEOUT to ensure that the room does not enter the vacancy state while
regularly occupied.
