BEFORE INSTALLATION
The LP916A, B and C Pneumatic Remote Bulb Thermostats
provide proportional control of heating or cooling in induction
units, fan coil units and unit ventilators. A wide throttling range
model is available for duct discharge control of heating or
cooling coils and mixed air dampers.
CAUTION
Equipment Damage Hazard.
Do not rotate the thermostat control shaft more than
two revolutions clockwise from the original position as
received. Rotating the shaft more than two revolutions
from the original position can cause permanent
damage to the thermostat.
The caution is also on a removable tag attached to the
thermostat and should remain attached until the system is
ready to start up. See Fig. 1.
