Location and Mounting
Mount the controller in any convenient interior location using
the two mounting holes provided. Mounting screws are not
included. Use controller dimensions in Fig. 1 as a guide.
Sensor Location
The 193987GA Sensor can be used up to 1000 ft (304m)
from the T775 using standard AWG 18/2 unshielded wire. If
longer than 25 feet in an electrically noisy environment, use
shielded cable. Locate the sensor on pipes, in immersion
wells, in wall-mounted cases or on a bulb holder.
Multiple sensors can be parallel-series wired to sense
average temperature in large spaces. In order to maintain
control accuracy, be sure the number of sensors parallel-
series wired is of the n2 power (i.e., 1, 4, 9, 16, etc). See
Fig. 2.
Fig. 2. Parallel-series wiring of sensors.
Sensor Mounting
Mount the sensor on a wall or panel for sensing space
temperature (Fig. 3); strap it to a pipe, or insert it into a well
(Fig. 4) for hot/cold water sensing; or tape it to a standard
cap or bulb holder for duct air sensing. To prevent moisture or
condensation entering the sensor through the leadwire holes,
mount the sensor with leadwires exiting the bottom of the
sensor.
NOTE:
Use heat conductive compound in immersion wells.
