1.1. Temperature Monitoring and Alarms
To efficiently monitor the walk-in air temperature, WIMS 200 is equipped with a highly accurate temperature
probe mounted inside the walk-in. The temperature readings are displayed on an ultra bright dot matrix LED
display.
The controller alarm system is comprised of a high and low temperature alarm with built in trigger delay to
allow small temperature fluctuations (occurring in daily walk-in operations such as door openings, door
closings, and evaporator defrost cycles) without triggering the alarms. The alarm’s set points and delay times
are fully programmable to the user’s needs.
In case the air temperature inside the walk-in is reaching an alarm condition, WIMS 200 uses visual and audible
alert methods. In addition to the integrated buzzer and alarm display message, the controller has a
120V/60Hz/150W output for additional external alarm devices (optional).
1.2. Door Frame Heater Temperature Control and Monitoring
Door frame heater control and monitoring is done by two different methods that work in conjunction to save
energy and to maintain the door frame heater temperature within a preset range.
A temperature probe is mounted on the door frame heater wire to accurately monitor its temperature. Viewing
the door frame heater temperature is as easy as pressing a button.
