Zone Sensor w/o Remote Set Point Adjustment
The standard Microtech III room temperature sensor package
that does not include set point adjustment can be used with
any applied rooftop Microtech III control conguration. It
includes a tenant override button. This zone sensor must be
eld installed and eld-wired to the unit using twisted pair,
shielded cable (Belden 8761 or equivalent).
NOTE: Shield cable ground should be terminated at the
control panel.
Zone Sensor with Remote Set Point Adjustment
The standard Microtech III room temperature sensor
package equipped with a set point adjustment potentiometer
can be used with any applied rooftop Microtech III control
conguration. This sensor package also includes a tenant
override button. This zone sensor package must be eld
installed and eld wired to the unit using twisted, shielded
cable. Four conductors with a shield wire are required. Cable
with 22 AWG conductors (Belden 8761 or equivalent) is
sufcient.
NOTE: Shield cable ground should be terminated at the
control panel.
Tenant Override (Timed)
The tenant override button provided with the two optional
zone temperature sensor packages can be used to override
unoccupied operation for a programmed time period. This
time period is adjustable between 0 and 5 hours using the
Tenant Override parameter in the Timer Settings menu in
the Extended Menus of the keypad/display (default is 2
hours). Except for the fact that it is temporary, tenant override
operation is identical to occupied operation. Pressing and
releasing the push button switch on the sensor momentarily
shorts zone temperature sensor ZNT1, resetting and starting
the override timer. The unit then starts up and runs until the
override timer times out.
NOTE: Hold the button in for at least 1 second but not more
than 30 seconds
NOTE: The installations and operating instrictions for the
digital readout space sensor are available in IM 1199.
