General
This section shows how to remove and replace thermostat
and humidistat covers and how to install Inserts over the
setpoint and DAY/AUTO slots at the bottom of covers. This
section also lists recommended paints for covers that can be
painted and describes painting procedures.
Cover assembly and disassembly differs between
conventional and Quick-Mount stats. On a conventional stat
the cover mounts to setscrews in the backplate, while on a
Quick-Mount stat the cover mounts to setscrews in the stat
body (Fig. 14).

To determine the cover mounting method, look at the holes at
the top of the cover (Fig. 15). If the setscrews are raised
against the back pair of slots (toward the wall), the setscrews
are in the backplate and the stat is a conventional stat. If the
setscrews are raised into the front pair of holes, the setscrews
are in the stat body and the stat is a Quick-Mount stat.

Humidistat/Humidity Sensor
General
After installing the humidistat, set the humidistat to the
desired setpoint and let the system operate long enough to
stabilize. The length of time required for stabilization depends
on system response time and could be only a few minutes or
as long as several hours. Verify that the system has stabilized
before checking calibration.
NOTE: Humidistats and humidity sensors are factory
calibrated and should require only a bleed-off check
to ensure correct operation. The throttling range is
factory set and should not require adjustment under
normal operating conditions.

3. Wait 5 to 10 seconds (30 to 60 seconds for TP973) to
allow thermostat to build up branchline pressure.
4. Turn setpoint indicator down slowly.
5. If thermostat begins to bleed off between 1 degree F
(0.6 degrees C) and 3 degrees F (1.7 degrees C)
above room temperature, no further calibration is
necessary. If recalibration is needed, see
RECALIBRATION.

Recalibration
The procedures in this section assume that a calibration
check has been performed (see CALIBRATION CHECK) and
that the thermostat has not operated correctly.
NOTE: Thermostats have either an adhesive paper dot or
an antihum spring, as shown in Figure 50. Verify that
either the adhesive paper dot is in place or the
antihum spring just touches the throttling plate and is
not wedged against it. If the antihum spring needs
adjustment, see TP970 Series Pneumatic
Thermostats Service Data 75-7134.
CAUTION
Excessive handling during calibration can heat the
thermostat and cause an inaccurate reading.

APPENDIX: BACKPLATES
General
Backplates differ between conventional and Quick-Mount stats.
A conventional stat backplate has setscrews at the top and
holds the stat body with tabs at the sides. A Quick-Mount stat
backplate does not have setscrews and holds the stat body with
tabs at the top and sides.
