Calibration
General Instructions
Calibration and readjustment of
the T-5800 Receiver-Controller
should only be done by a
qualified Johnson Controls
representative, equipped with the
proper tools. An X-200-173
Calibration Kit (see Fig. 6,
ordered separately) is available
for making adjustments and
pressure checks on the
T-5800. This kit provides all of
the necessary gages, regulators,
and connectors for a more
convenient and quicker
calibration procedure.
An X-200-140 Hypodermic
Needle Test Probe and
appropriate gage (see Fig. 7,
ordered separately) is also
available for troubleshooting, for
test point readings, or for final set
point adjustments under actual
job conditions. Note: Figure 8
illustrates an alternative
method of checking pressure
readings on the
T-5800 where use of a
hypodermic needle test probe
is prohibited.

Set Point Adjustment
To make adjustments to the set
point, proceed as follows:
1. Consult the system drawing to
determine the required set
point value. Convert this
value to the pressure
equivalent; see example
highlighted in Fig. 10 (75°F on
a 50 to 150°F range would be
a set point of 6 PSIG).
2. Take a set point pressure
reading using the appropriate
method and gage, as
illustrated in Fig. 8. Adjust the
local set point dial or the
remote adjuster (manual or
automatic) until the pressure
matches the value noted in
Step 1. Remove the pressure
reading device and reconnect
the jumper (if applicable).
