PRODUCT DESCRIPTION
The ICUBE™ Adaptive Defrost Module, when added to an existing Grässlin™ DTAV40 - Defrost Control, provides the
DTAV40 Control with the ability to skip scheduled defrost events when they are not needed in order to save energy. Up to
four thermistor probes may be added to the control in order to monitor multiple evaporator coils. Thermistor probes may be
installed up to 400ft (122 m) away from the ICUBE™ module at a remote dedicated or multiplex condensing unit (indoor or
outdoor) or within the freezer/cooler box. No changes to the installed defrost control terminal wiring (such as the wiring for
fans, defrost heater, or thermostat) is required.
To order additional thermistor probe kits (for example, to connect multiple evaporators to one control), use part number
178GR10K-1.
ICUBE™ Adaptive Defrost Module Contents – Part Number DDFM
The kit includes:
• One 10 ft (3.05 m) thermistor probe, with clip
• One 6 ft (1.83 m) input lead

1. Disconnect all power to the control at the circuit breaker
or disconnect switch. More than one circuit breaker or
switch may be required to de-energize the control and
all connected loads.
2. Plan the length of field-supplied copper wire needed
to connect the thermistor probe from the evaporator
coil to the input lead. (This wire may be #18-14 AWG
shielded or unshielded up to 400 ft (121.92 m) long).
3. The existing control may be installed in an enclosure (as
shown in FIG. 3, for example) or secured via a bracket
inside the condensing unit control panel (as shown in
FIG. 4, for example). The installation of the ICUBE™
module is the same for both instances.
