When partially locked, the screen indicates Screen Locked for 5 to 7 seconds whenever the user attempts to press a key that is locked. Pressing a locked key, while Screen Locked is shown, flashes "Screen Locked" on the screen. In this mode, all keys are locked except the Temperature Up and Down arrow keys:
— User can change temperature up or down but cannot change schedule settings.
— Temporary temperature change lasts until next scheduled period and that time shows on screen.
— To cancel temperature override and begin following schedule, press Cancel key.
— To unlock screen, see Installer Setup section.
The thermostat microprocessor-based control requires that the user understands temperature control and thermostat performance. A conventional mechanical or electronic thermostat does not control temperature precisely at setpoint.
Typically there is an offset (droop) in the control point as the system load changes. This is a phenomenon that most people in the industry know and accept. Many factors contribute to offset including switch differential, thermal lag, overshoot, cycle rates and system load.
The thermostat microprocessor simultaneously gathers, compares and computes data. Using this data, it controls a wide variety of functions. The special proprietary algorithm (program) in the thermostat eliminates the factors causing offset.
This makes temperature control more accurate than the conventional mechanical or electronic thermostats. The temperature control algorithm is called proportional plus integral (P+I) control
