R7500C Wide Range Proportional
Temperature Controller
INSTALLATION INSTRUCTIONS
RC186
They are fastened to the mounting surface through the two
diagonally opposed mounting holes in the back of the case.
See Fig. 1.
For access to the mounting holes, remove the cover from the
case by loosening the cover mounting screw.
The mounting holes are now visible through the circuit board
notches in the upper right and lower left-hand corners.
Determine placement of the mounting holes in the surface
and scribe the mounting hole locations. Drill pilot holes and
fasten with No. 10 screws.
BEFORE INSTALLATION
Refer to job drawings for specific installation information and
mounting location. Main and compensation sensors (when
used) must be 500-ohm Balco sensors (L7022, L7025,
L7033, T7506 or T7001).
This controller is surface mounted through the two holes in
the back of the case.
Observe ambient temperature (30 to 140F) (0 to 60C) and
relative humidity (5 to 95%) limitations.
No special tools are required to install this controller.
CAUTION:
This controller requires a 11 to 12V dc power supply
for proper operation. The power may be supplied by
an R7503 Modutrol* Motor Converter, R7504 Two-
Position Converter, RP7505 Pneumatic Transducer,
Electronic Modutrol Motors M734K or M745J, any
other device designed for use with this Temperature
Controller, or a separate dc power supply. This
controller outputs 4 to 7 Vdc across the proportional
band setting. It is designed to work with motors and
actuators that expect a 4 to 7 Vdc input signal.
MOUNTING
This controller can be surface mounted in any convenient
location such as on duct walls, end compartments of unit
ventilators, etc.
