FEATURES OF WALL MOUNTED CONTROLLER 1. Supplied wall mounted controller allows the user to easily control the unit’s operation. 2. LCD display that indicates: a. Clock with day and time b. Room temperature and set point temperature (either Fahrenheit or Celsius) c. Operation mode status d. Fan mode status e. Fan speed status f. Set program status g. Program run and stop h. Self-diagnostic codes i. Keypad lock 3. Programmable clock/timer function.
FEATURES OF CM25 1. The CM25 is equipped with a variable speed compressor, which is driven by state of the art inverter technology. A variable speed compressor automatically adjusts its speed as the heat load in the room changes. With its soft start up, a variable speed compressor reduces start up wear on the compressor and eliminates in-rush current resulting in no dip in the power supply. 2. Fire alarm control panel connection with automatic shut off. 3.
