SETTING A ZONE NUMBER
Press the
SETUP
key again and the
LCD will display the word ZONE. The
factory default is 00. This number can
be used to identify each SMT-AZC
thermostat Network or when used in
multiple stand-alone applications. Use
the
UP
and
DOWN
keys to assign a
ZONE number from 00 to 99. (Figure 6)
SETTING THE HEATING LIMIT
Press the
SETUP
key again and the
LCD will display the heating limit. The
factory default is 24° C. Press the
UP
and
DOWN
keys to change the heating
limit setting. It is strongly recommended
that the limit not be set above the
factory default setting. (Figure 7)
SETTING THE COOLING LIMIT
Press the
SETUP
key again and the
LCD will display the cooling limit. The
factory default is 68° F. Press the
UP
and
DOWN
keys to change the cooling
limit setting. It is strongly recommended
that the limit not be set below the factory
default setting. (Figure 8)
SETTING THE ACTUATOR SPEED
Press the
SETUP
key again and the
LCD will display the actuator speed. The
factory default is 90 seconds which is
the time it takes the actuator to drive the
damper blade fully open or fully closed.
This is a critical step in the SMT-AZC
setup since the thermostat can be used
with a variety of 24 Volt actuators. If you
are unsure of the actuator speed, place
the actuator in the fully closed position
and then apply 24 Volts to common and
normally open. The time it takes to drive
the damper blade fully open equals the
actuator speed setting. (Figure 9)
