| ERC-248
Electronic Defrost Control |
|
The
ERC-248 electronic defrost control is designed to control the timing
of defrost cycles in commercial refrigeration equipment such as reach-in's,
walk-in's, and refrigerated fixtures.
- Compact design.
- Simple selectable settings:
- Defrost interval (from 2 to 48 hours).
- Defrost duration (from 1 to 63 minutes).
- 50 or 60 Hz operation.
- Two defrost types:
- Timed interval.
- Accumulated Compressor run time.
- Three types of defrost termination:
- Temperature (requires external thermostat).
- Pressure (requires external pressure switch).
- Time duration only
|
- Time backup feature terminates the defrost cycle based on
time should the external termination device fail to function.
- Manual Defrost can be accomplished by means of a push button
if desired.
- Microprocessor-based design assures high reliability and
accuracy.
- Cost effective solution.

ERC-2
Electronic Refrigeration Control
The
ERC2 series control provides complete refrigeration control for
many types of commercial refrigeration equipment such as reach-in's,
walk-in's, condensing units, and other refrigerated fixtures.
|
|
- Offers complete control functionality, replacing a defrost control,
temperature control, defrost termination switch, thermometer,
and fan delay switch.
- Usable with electric heat, hot gas, or off-cycle defrost.
- Electronic control offers more reliable and accurate operation
while allowing control parameters to be customized for each application.
- The control incorporates a digital display module that provides
readout of time, temperature, and diagnostics. The digital display
module also has a touch keypad for simple programming of desired
control parameters.
- The digital display module can be remotely mounted and connected
to the ERC-2 with a simple telephone jack cable or mounted directly
on the ERC-2 case.
- Incorporates a real time clock.
- Case incorporates the same size and mounting footprint as the
industry standard 8000 series Paragon defrost controls.
- Includes two temperature sensors (space and coil temperature).
- UL component recognition, CSA listed, NSF approved.
- 120 or 208/240 VAC 50/60 Hz operation.

- Wide ambient condition operating range -40F to 122F; 0 - 95%
RH.
- Operating parameters can be pre-programmed by Ranco.
- The ERC-2 incorporates a capacitor that retains the time of
day for up to 100 hours after a power failure.
- All other program parameters and settings are maintained in
an EEPROM processor which means that these are permanently saved,
regardless of the duration of any power outage.
- If there is a sensor failure, the ERC-2 can detect this and
revert to a backup operating mode until the sensor can be replaced.

ETC
Electronic Thermostat
The
ETC electronic thermostat, like its ET85 counterpart, utilizes microprocessor
technology to provide a very user-friendly programmable one or two
stage thermostat that offers unparalleled flexibility of use. Applications
are numerous; including refrigerated fixtures of all types as well
as many HVAC applications that incorporate one or two stages of
heating and/or cooling.
