Application
The Innotech M2K05 Controller is designed to provide complete control
of air conditioning systems for commercial applications, where control
over two zones (eg: Day / Night) is required.
Features
• LED Display of Temperature and Program functions
• Control Station fits standard electrical wall plates
• Two core screened cable simplifies connection between the control
station and controller
• Adjustable Proportional Band, Dead Zone, Compressor Restart Time
and Setpoint Range
• Able to operate as 1 cool, 1 electric heating or as reverse cycle heating
or cooling
• 7 Day 24hr Real Time Clock or Adjustable Timer function
• Programmable Schedules, 4 events per day
• Two Zone (Day / Night) control with option of 1 or 2 temperature
sensors
• Adjustable auto zone change over times
• External A/C fault and Start/Zone change inputs
• 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.
