The A/ENT-CTRL and A/ENT-DIFF are low cost Enthalpy
controllers that measure both temperature and humidity
and converts them into a sourced relay output. The
supply voltage to the A/ENT-CTRL/DIFF is common to
both the N/O or N/C contacts of the 10A Form 1C Relay.
The relay is controlled or switched by selecting the
proper mode switch within the unit. The A/ENT-CTRL-F1C
has the same features as the A/ENT-CTRL except for
the switch relay output which is a 10A Form 1C dry
contact referaced to the supply voltage common. f
other resistance-based humidity sensors that utilize
water-soluble polymer coatings. This technology enables
these sensors to fully recover from condensation and
enables the sensor to maintain its accuracy over time.
Despite its accuracy, the Advanced Ceramic Technology
sensor and related circuitry is economical.
All of the A/ENT-CTRL and A/ENT-DIFF are calibrated
using a NIST Traceable temperature and humidity controlled
environmental chamber. Factory selectable calibration
can be achieved for elevations of 0, 1000, 2000, 3000,
4000, 6000, 8000, and 10000 feet. Use reverse action
in the A/ENT-CTRL/DIFF unit to change the NO/NC switch
action.
All of the A/ENT series units come with a five year
factory warranty.
