Installation Electrical
The liquid crystal display (LCD) displays zone temperature, temperature setpoints, week day, time,
and operational mode symbols.
The options menu is used to enable or disable these applicable functions:
Morning warm-up, economizer minimum position override during unoccupied status, heat
installed, remote zone temperature sensor, 12/24 hour time display, and daytime warm-up. See
Table 15 on page 48 for the Temp vs Resistance coefficient if an optional remote sensor is used.
During an occupied period, an auxiliary relay rated for 1.25 amps @ 30 volts AC with one set of
single pole double throw contacts is activated.
High Temperature Sensor (BAYFRST003*)
Provides high limit "shutdown" of the unit.
The sensor is used to detect high temperatures due to fire in the air conditioning or ventilation
ducts. The sensor is designed to mount directly to the sheet metal duct. Each kit contains two
sensors. The return air duct sensor (X1310004001) is set to open at 135 degrees F. The supply air
duct sensor (X1310004002) is set to open at 240 degrees F. The control can be reset after the
temperature has been lowered approximately 25 degrees F below the cutout setpoint.
