• The WIM-DL provides temperature data-logging with the storage capacity of up to 4000 entries.

• The WIM-H provides Humidity monitoring and alarming.

AD-1104

AD 1104-R

AD-1108

AD-1108-R

• Calls from 4 to 8 numbers to verbally report alarm conditions

• Can monitor up to eight inputs.

• Dry Contact Alarm Relay Closures

• Status Switches

• Doors

• Temperature Sensors

• Humidity Sensor

• Moisture Sensor

Temperature Control - Room Controls

Walk-In Control System

WIC

WIC2

WIC3

The Walk-In Control System provides the same alarming capabilities as the WIM(2,3), excluding entrapment, with the addition of temperature control and Electric or Off-Time defrost for one, two or three temperature zones or walk-in cooler/freezers.  

• Provides pilot-duty rated control relays for Evaporator Fans and Defrost Circuits.

• Provides 30A, 1 ph control relays for each defrost and fan circuit (available only with the one or two zone units)

• Provides 30A, 3 ph control relays for each defrost and fan circuit (available only with the one or two zone units)

• WIC-R can provide a reheat circuit for maintaining of critical temperature systems.

Lead-Lag Control System

WLL

W3LL

The Lead-Lag Control System controls the temperature and defrosts of a single cooler/freezer with two or three parallel, redundant systems.  The WLL will alternate between systems, providing even control runtime

• Provides two or three stages of cooling.

• Rotates Primary designation between systems automatically.

• Provides pilot-duty rated control relays for Evaporator Fans and Defrost Circuits.

• Provides 30A, 1 ph control relays for each defrost and fan circuit (available only with the one or two zone units)

• Provides 30A, 3 ph control relays for each defrost and fan circuit (available only with the one or two zone units)

WCPCS-Dual

• The Wizard CPCS can be configured to operate as an independent system, or as the controller of side of a completely redundant system.

• Will operate as a two stage temperature control when in the dual mode.

• Will alternate primary control between the evaporators when installed in the dual mode.

• The Wizard can operate defrost circuits that are Off-time, Hot Gas, or Electric.

• Temperature Alarm -- Three level temperature alarm.  High Temperature Level One, "Alert" Level; High Temperature Level Two, "Action" Level; Low Temperature Alarm Level.

• Door Open Alarm -- The Wizard can monitor a Normally Open Dry Contact Door Switch.

• The Wizard has a timer log that counts the total amount of time that a door is open over a 24 hour period.

• The Wizard can monitor a Normally Open Dry Contact Compressor Proofing Switch provided by the condensing unit manufacturer.

• The Wizard makes any refrigerated room Uniform Mechanical Code Compliant with the addition of a Sherlock Refrigerant Sensor.
