30 • iPro Case Controller I&O Manual FM V1.01

026-1738 Rev 1

Note that if the Modbus address or baud rate is changed, the controller must be rebooted.

10.3.4.3. Superheat and Suction 

Control-Refrigeration Relay

The management of the refrigeration relay in this mode is the 

same as described in 

Section 10.3.3., 

Suction Control Mode

.

10.3.5.   Defrost Control and Operation

10.3.5.1. Initiation of Defrost

The case controller defrost is managed completely internally by 
the case controller and needs no instructions from a supervisory 

controller or E2E. The case controller has an internal schedule for 

defrost cycles. Based on the start time and the number per day, the 
controller will evenly space the defrosts based through a 24 hour 

day. For example, if the start time is 0:00 and the number per day 

is 4, the controller will schedule 4 defrosts evenly every 6 hours at 
0:00, 6:00, 12:00, and 18:00. When a scheduled defrost time is 

reached, the controller starts the defrost cycle and drives the EEV 

valves to the percentage defined by 

SHDef%

 and drives the 

EEPR valve to the parameter 

SuctionDef%

. The defrost relay is 

switched to ON and the refrigeration relay is switched to OFF.

10.3.5.2. Master/Slave Defrost of a Lineup

If the case controller is a device that is part of a common 

refrigeration circuit lineup, the controller is considered either the 

lead/master case or a slave case. In a lineup of masters/slaves the 

master manages defrost for the entire circuit. When the scheduled 
defrost time is reached for the circuit, the master controller will 

start defrost (if no lockout is present) and communicate to all slave 

controllers to start a defrost cycle. Once in defrost, all case 

controllers will execute defrost and terminate according to their 

own individual termination settings. The master controller will be 

notified when each slave controller terminates its defrost cycle. 

A detailed description of defrost termination is found in 

Section 

10.3.5.4., 

Defrost Termination

 and 

Section 10.3.5.5., 

Wait Mode

.

10.3.5.3. Defrost Operation of Relays and 

Valves

Whenever the defrost cycle begins, the case controller drives the 
electronic valves to their respective defrost positions as defined by 

parameters 

SHDef%

 and 

SuctionDef%

. The refrigeration 

relay is driven to the OFF position and the defrost relay is 
switched to ON. 

The evaporator fan operation during defrost is governed by the 

parameter 

FanOp

. The options are shown in the table below: 

10.3.5.4. Defrost Termination

The defrost termination is managed locally by the case controller. 

The termination options are: temperature and time. 

Temperature 

-When temperature termination is selected, the 

terminating sensor must be specified by parameter 

dTS

: the 

options for sensors to select are: defrost termination, discharge air, 

or coil outlet. Once the combined termination value reaches the 
defrost termination setpoint, the defrost cycle is terminated and 

the system enters Drip mode (if drip time is programmed). 

Following Drip mode, the system enters Wait mode. Wait mode is 
only entered if the controller is a part of a master/slave lineup 

network. If there is no master/slave network, wait mode is 

skipped. During Temperature Termination mode, the case 

controller is always monitoring maximum time, and if the 

maximum time duration is ever exceeded, the defrost is 

terminated immediately.

Time 

-When time termination is selected, the defrost cycle runs 

for a time value only and then terminates. No temperature sensors 
are considered. Following the time termination, the case 

controller performs drip time if applicable and then enters Wait 

mode.
