Digital Temperature Controller
Overview
The microprocessor-based digital temperature controller
performs the functions of controlling the enclosure
temperature while monitoring operating limits and refrigerant
pressures. Temperature and alarm status are indicated
on the front panel in easy-to-read LEDs (0.57”x 0.29”
[14.5 mm x 7.3 mm]). It also records the maximum and
minimum temperatures within the enclosure.
The controller includes a compressor anti short-cycle time
delay (Parameter
AC
= 5 minutes) for compressor protection.
A factory-set bypass time delay of 2 minutes prevents nuisance
trip-outs caused by cold weather startups and transient high
temperature limits.
The inputs include one enclosure temperature probe (NTC
input), one condenser coil temperature probe (NTC input)
and one low pressure switch digital input. Select parameters
(listed in the setpoint table) are configurable through the
keypad.
