BASIC DISPLAY / USER INTERFACE
IMPORTANT NOTE:
Your Intuitive Evaporator Control is pre-programmed (with the exception of bonding multiple controllers paired with
a single condensing unit) at the factory and will begin operating as soon as power is applied using the following
default settings : ROOM TEMP (tS) = -10 °F (freezer) or 35 °F (cooler), REFRIGERANT (rF ) = R-404A,
DEFROST TYPE (dtY) = Defrost Type (Air or Electric). Use this manual to make any adjustments you require.

Diagnostics Mode
The ESP+ has been programmed with a diagnostics mode. When activated in the
advanced setpoints menu, the controller energizes each relay for 30 seconds.
When the compressor relay is on the EEV will regulate to the Superheat setpoint.
To activate diagnostics mode, go to DIA in the Advanced Menu. Press and hold
ENTER
until fan relay FAr is displayed. The defrost relay DEr, then compressor
relay Cpr will be energized in turn.

version.
Bonding (Multi-Evap Applications)
Bonding allows multiple contollers to synchronize refrigeration and/or defrost. It is
required on systems with multiple evaporators on one condensing unit with no un-
loading capability. Bonding can be done easily through the controller webpages, but
can also be done from the ESP+ Basic Display. Bonding is limited to two controllers
through the ESP+ Basic Display.
Run an ethernet cable CAT5E or higher between the two controllers. Plug the cable
into the Ethernet port at each controller. The cable will remain permanently plugged
into both controllers in order to allow the sychronization. Cables can also be run
from each controller to a network switch, however, only the two controllers to be
bonded can be connected to the switch during the bonding process.
Go to bnd in the Advanced Menu. Press and hold
ENTER
until the red LED is blink-
ing. Wait several seconds. PAS means the bond was successful and both control-
lers will restart. FAi means the bond failed, check cables and ensure only two
ESP+ controllers are on the network before trying again.
To unbond controllers from the display, go to Unb. Press and
ENTER
hold until the
red LED is blinking. Wait several seconds. The controllers will unbond and restart.
If bonded to more than one controller, the controllers must be unbonded using the
webpages.
Note: Only controllers with the same rmware and version can be bonded.

11. To ensure the evaporator units are bonded properly, click the Navigation button
to expose the menu.
12. Click Setpoints.
13. Click Bonded Controllers.
14. From the drop down menu of the Multi Evap Cool tab: select Synchronized.
Multi Evap Defrost will either make all the bonded controllers go into defrost
at the same time (Synchronized) or limit the system to only one evaporator at
a time (Independent). Multi Evap Sensor tells the controller whether or not to
share sensor information. For example, if the controllers are “Shared” and one
controller was to lose its air temperature sensor, then it could continue running
using the temperature read by the other bonded controllers. This should be
the default mode. If the controllers are located in different spaces, therefore
controlling at different temperatures, then “Independent” mode should be
selected. If a controller loses a sensor, the controller will continue to run based
the default safety mode for the current alarm.
15. Locate and click the Refrigeration tab. Select the type of Multi Air Tmp Ctrl
(Warmest or Average air). This selection will determine which method is used
to control the temperature.
16. Click Save to save the settings.
17. The second controller and subsequent controllers must be congured to match
the “Multi” settings of the rst controller. This is accomplished by entering
the IP address of the second controller in the browser, and navigating to the
Setpoints and repeating the process illustrated in this section.
The bonded ESP+ controllers will now be operating in Synchronized mode. You can
view the current operating status for each controller by connecting to the router
and navigating to the IP address of each.
To Unbond:
1. Follow steps 1-9 above.
2. Click "Unbond". Controllers will
reset and restart
