Application
The Innotech Micro2000 Series Controllers are designed to be used
in commercial applications to provide complete control for air
conditioning systems. Specifically for applications where a condenser
water pump interlock system is required.
Features
• Condenser Water Pump Interlock Control
• LED Display of Temperature and Program functions
• Control Station fits standard electrical wall plates
• Four core screened cable simplifies connection between the control
station and controller
• Adjustable Proportional Band, Dead Zone, Compressor Restart Time,
Aer hours Timer and Setpoint Range
• Able to operate as 2 cool, 2 electric heating or as reverse cycle heating
or cooling
• Aer Hours function
• 7 day, 24 hour Real Time Clock
• Programmable Schedules, 4 events per day
• Storage of Accumulated Aer Hours Run Time
• All adjustments from the control station
The Clock is not battery backed. Time and Date will need to
be set every time power is cycled if the Time Clock function is
enabled. Schedules and Parameters are saved even if power
is lost.
