E-Accustat®II
Series Electronic Thermostats
Description:
PSG Controls, Inc.,
manufacturer of the ACCUSTAT®, has designed the E-ACCUSTAT®, with adjustable
electronic sensing. As with the other ACCUSTAT products the E-ACCUSTAT
features the same high reliability and quality, which you expect from PSG. The
E-ACCUSTAT does not require sensors, as the electronic sensing is built into the
control. Wiring is the same as the pre-set ACCUSTAT or any conventional
thermostat, just set the temperature and place the locking cover on the base.
Application:
May be used on most low
voltage single / multi stage air conditioning and heating systems.
|
Features: |
Electronic Sensing--No
mercury sensors needed.
Adjustable Cycle Rates--Heating and cooling cycle rates can be set
independently.
Easy Front Wiring--Easy wiring using screw terminal block. The same
wiring as conventional bi-metal thermostats.
Locking Cover--Provides tamper resistant operation. Special key
needed to open the cover (included).
Precise Temperature Control--Adjustable temperature setting with
accuracy of ±1.0°F.
Intelligent Fan Switching--Auto/On - when control is in un-occupied
mode fan operation switches to auto.
Occupied/Un-occupied Modes--Mode selection can be done using any
device that will provide a dry contact closure, such as timer, motion
sensor, burglar alarm, etc. Occupied and Un-occupied temperatures are set
using independent dial adjustments - no complex programming!
Fresh Make-Up Air--Fresh air can be provided on an hourly basis using
a built-in damper control on selected models.
Adjustable Dead Band--Dead band can be set using a dial-up setting
from 1° - 5° F.

Specificications: |
|
The HVAC
temperature control shall be tamper resistant having an integral locking
cover. It shall be a digital control without any display. The
sensor shall be electronic sensing. The switching of the load shall be
done with relay contacts. Dial-up setting shall be used in setting
temperatures, cycle rates, etc. The control shall have push button
system and fan selection with LED indicators. In addition to accurate
temperature control of ±1°F,
selected models must be capable of operating dampers to bring in fresh air
on an hourly basis to meet the fresh air requirements. |
