SPECIFICATIONS
IMPORTANT
The specifications given in this publication do not
include normal manufacturing tolerances. Therefore,
an individual unit may not exactly match the listed
specifications. Also, this product is tested and
calibrated under closely controlled conditions and
some minor differences in performance can be
expected if those conditions are changed.
Models (See Table 1):
The T775J family of electronic remote temperature controls
provides reset control for chillers, heating and cooling
systems, and other applications where electronic accuracy in
addition to remote sensing is desired.
T775J provides reset control with
two
temperature inputs and
one of either 4 to 20 mA, Electronic Series 90, or 0 to 18 Vdc
Proportional + Integral modulating output with 0 or 1 relay
output stages, or 1 to 2 relay output stages with no
modulation. Includes two part number 193987GA
