OTHER OPTIONS AND FEATURES
ADAPTIVE RECOVERY OPTION
If your thermostat has been configured for programmable operation, your installer can add the Adaptive Recovery Option. Adaptive Recovery compares the space temperature deviation from the set temperature for the next scheduled event and rate of recovery history to bring the equipment on and reach the next temperature setting at the scheduled event start time. Example: If you program a heating temperature to be 21 degrees at 6:00 PM, Adaptive Recovery will calculate when to bring the equipment on so that the temperature will be 21 degrees at 6:00 PM.
CLEAN SCREEN
It is recommended that the touch screen be cleaned periodically. Use a slightly moistened clean, nonabrasive cloth. Touch the screen until the LCD lights up. Touch the Clean Screen window. All normal operating functions will be hidden and locked. The thermostat will count down from 15 seconds while you clean the screen. If more time is required, simply touch the Clean Screen box again
LOW BATTERY INDICATION
Your thermostat uses two AA batteries to keep the time-of-day clock running in case of a power failure. In some applications, battery power is also used to control the heating and air conditioning equipment. When the Low Battery icon appears on the screen the back light is disables, you should change the batteries immediately. If the batteries are not changed and the batteries become weaker, the display will blank completely and the beeper will chirp every minute (Between 8:00am and 9:00 pm only) to remind you to change the batteries.
CHANGING THE BATTERIES
Press in on the battery access compartment, it will pop out a small way. Slide the drawer out. Install two AA ALKALINE batteries matching the + (Positive) and – (Negative) orientation. Push the battery compartment in until it clicks shut. When the batteries are properly installed, the touchscreen display will resume normal operation with no loss of programming. If the batteries are swapped out quickly (less then 5 minutes) the current time will remain unaffected.
NOTE: Use fresh Alkaline batteries only. Do not use rechargeable, super heavy duty or any other type of battery other than Alkaline or erratic operation may result
