824 Programmable Comfort Control 6. Basic Operation 6.1 PI Control Higher CPH results in highter indoor temperature control but shorter, more frequent cycles. The 824 Control uses Trane’s proprietary control schemes to provide both comfort and energy efficiency.
PAGE 30
Installation Guide 6.6 Stage Inhibits When the stage threshold is exceeded, a stage inhibit is applied. The stage inhibit calculates the rate of recovery over a 10-minute period and determines if the next stage is required to meet the current demand. If the rate of recovery is great enough, then a new 10-minute inhibit is enabled. The Control will not go to the next stage of operation until it determines that the current stage cannot satisfy the current demand.

824 Programmable Comfort Control Feature Description 1-Touch Presets The 1-Touch Presets allows for an immediate change to the setpoint status. Set the desired temperature for the three status modes (Home, Away & Sleep). The control will remain in the selected mode until another mode is selected or the program reaches a new schedule period.
PAGE 34
Installation Guide Feature Description Duty Cycle When the control is requesting less capacity than the system can deliver, the control will duty cycle to meet the required demand. The length and frequency of each duty cycle is based on the cycle rate and current load value. There are two requirements before dehumidification is enabled: • Dehumidification must be enabled through the Installer Setup. • The indoor relative humidity must be above the desired setpoint.
PAGE 35
824 Programmable Comfort Control Feature Description There are two options available for humidification: Humidification • Indoor RH setpoint—this controls the humidifier based on the desired indoor humidity setpoint (options from 10%–45%). • Frost Control setpoint--The control references the outdoor temperature and indoor environment to calculate the risk of frost or condensation on interior walls and windows.

Installation Guide Feature Description Security initiates a keypad lockout. The control can only be accessed by a four digit pass code which can be configured in two different formats: Security Pin Lock: When the Pin Lock is selected, the control is completely locked. The user will need to enter a four digit password to change any setting (the default is “1234”).
