Type A36AHA 4-Stage Computer
Environmental Temperature Control
Application
The A36AHA 4-stage
temperature control operates
electrically controlled heating
and cooling equipment to
maintain desired temperatures
in a computer room.
All Series A36 controls are
designed for use only as
operating controls. Where an
operating control failure
would result in personal injury
and/or loss of property, it is
the responsibility of the
installer to add devices
(safety, limit controls) or
systems (alarm, supervisory
systems) that protect against,
or warn of, control failure.
Features
· Totally enclosed contact
units.
· Accurate repeat
performance.
· Rigid, reinforced frame.
· Cushion mounting.
· Ambient compensated for
variations in ambient
temperatures.
General Description
The A36AHA control has an
open construction (less
enclosure) design for panel
mounting. The contact units
have color coded screw type
terminals. The SPDT contacts
of each stage are actuated from
a single liquid filled, remote
sensing element.
The main operating arm is
counterbalanced and spring
loaded for low pivot point stress
and minimal wear.
The A36 has a rugged steel
frame and the mounting holes
are fitted with shock absorbing
rubber grommets.
A single calibrated adjusting dial
permits moving all settings up or
down within the adjustment
range. Between stage
adjustments remain constant for
uniform temperature control,
regardless of the set point.
