The control icons shown above will be illuminated when the associated function is active. If the icons
are flashing, it means the function will be activated after the controller delays are finished.

The easy control has a “3” button interface.

• The “AUX HTRS/UP” button is used for activation or deactivation of the auxiliary anti-condensate
heaters or for increasing values.

• The “SET/MUTE” button is used to lock in a new value or to silence the alarm beeper.

• The “POWER/DOWN” button is used to turn the unit on/off or for decreasing values.

• Press the UP and DOWN buttons simultaneously to put into a manual defrost.

INITIAL SEQUENCE OF OPERATION

1. Cabinet is plugged in.

a. Display will show “F’ and the firmware version, then will show “P” and the parameter version.
b. Display will then show current cabinet temperature.
c. The compressor icon and the auxiliary heater icon may flash for a period of time,

indicating normal delayed start-up.
d. After the start-up delay, the compressor and evaporator fan(s) will start if the control is
calling for cooling. The fans may pulse on and off when the compressor is off to conserve
energy.

2. The control will cycle the compressor on and off determined by the Set-Point and Differential
Temperatures. (If the Set-Point needs to be changed, please see instructions on Page 6).

a. The Set-Point is the preprogrammed temperature which shuts off the compressor.
b. The Differential is the preprogrammed temperature that is added to the Set-Point

temperature that will start the compressor.

EXAMPLE: Set-Point is 36°F and the Differential is 4°F
The compressor and condenser fan(s) will cycle off at 36°F and back on at 40°F.

3. The control may be preprogrammed to initiate a defrost by time interval. (If additional defrost
cycles are needed or a manual defrost is required due to conditions, please see the instructions
on Pages 7 & 8).

a. During defrost, the defrost icon will appear in the display and the compressor will turn

off until a preprogrammed temperature or time is reached. During this time for freezers
only, evaporator fan(s) will also turn off and the defrost heater will be energized.

b. After a preprogrammed evaporator temperature or time has been reached, there may

be a short delay for both the compressor and evaporator fan(s) to restart.

c. After the defrost cycle is completed, the control will resume normal operation.

If you have any questions, please contact the Technical Service Department.

HOW TO TURN THE AUX (ANTI-CONDENSATE) HEATERS ON/OFF

Anti-condensate heaters are located around the door to eliminate condensation. In order to save energy
these heaters can be turned off.

1. To see the current state of the AUX (anti-condensate)
heaters, press and HOLD the AUX HTR button for 1
second. RELEASE the AUX HTR button. The display will
show the current state of the heater when the button is
pressed. In this case the heaters are currently ON.

2. To change the current state of the AUX Heaters, press
and HOLD the AUX HTR button. The display will show
the current state of heater operation. After 5 seconds,
the heater will switch to the opposite state and the
display will return to displaying the cabinet temperature.

RELEASE the button.

The control has a built in energy saving feature for the aux (anti-condensate heaters). When in
the ON position, the “AUX” icon may not illuminate indicating the AUX heaters are not currently
energized. The control will automatically energize the AUX heaters when the conditions require
these heaters to be activated.
