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.
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.

SELF-DIAGNOSTIC CODES & BUZZER PATTERN Self-Diagnostic Codes Self-diagnostic codes are displayed with “CHECK” on LCD panel of the supplied wall mounted controller under the following conditions. Note: When using the field supplied wall Self-Diagnostic thermostats, the self-diagnostic codes are code not displayed.
DAILY INSPECTION & MAINTENANCE Cleaning Air Filters The air filter on the evaporator return grill should be checked weekly for dust buildup. Clean or replace air filter on a weekly basis. If the unit is used in a dusty environment, more frequent cleaning may be required. A dirty air filter can reduce the air output, resulting in a decrease in cooling capacity.
