This reference should remain on site with
the installed KE2 Evap OEM controller.
Overview
The KE2 Evap OEM provides the energy savings, precise temperature control,
frost reduction, and communications capability of the KE2 Evaporator Eciency
in a compact and economical package. It replaces and performs the function
of multiple mechanical components such as the thermostat, defrost time clock,
defrost termination, and fan delay. The KE2 Evap OEM controls the liquid line
solenoid (LLS), evaporator fans, and defrost heaters (if present). It is able to
control an electronic expansion valve (EEV) to regulate superheat, but will also
function with a mechanical thermostatic expansion valve.
Defrosts are initiated by a proprietary calculation of actual evaporator
eciency. When evaporator eciency has dropped to 90%, the controller will
initiate a defrost. Defrost is terminated based on one or more coil temperature
sensors. To maximize eciency, fans may run for several minutes at the start of
a defrost before turning o and energizing heaters.
Fans are also managed in a unique way. If wired to control fans with fan
management enabled, during the o cycle the controller will intelligently cycle
fans based on room and coil temperature for precise room temperature control.
Fans should always be running when the controller is calling for refrigeration.
Communications capability on the KE2 Evap OEM was designed with the
service technician in mind. The controller has built-in webpages that show
system performance in real time, allow setpoint changes, provide a 30 day
room/coil temperature graph, and a 30 day datalog of all variables. The
webpages can be accessed by smartphone or tablet through a KE2 Therm Wi-
Fi accessory, a local network, or by plugging directly into the controller with a
Cat5e cable and laptop. If the controller is provided wired internet access, it can
be accessed remotely via KE2 SmartAccess.
