11RGFE Fan Coil orVariable Speed FurnaceA07115Fig. 29 -- G Input Wiring for System Shutdownwith (--B) Infinityt Control (Contact type selectable;Normally Closed (default) or Normally Open)High Stage TimerMinimum amount of time low stage must operate before high stageis activated. Ten to 60 minutes. 10 = defaultA demand of 5_ or more will override the staging timer.Off DelayS 90 secondsS 120 seconds (default)S 150 secondsS 180 secondsAmount of time the blower will continue to run after heating hasshut off.Setup -- Fan CoilHP/AC Airflow:S COMFORT (default) Cooling airflow is varied depending onhumidity and temperature demand settings. This selectionenables the full dehumidify and comfort capabilities of thesystem. When COMFORT is not selected, the unit will not runreduced airflows for dehumidification. Heat Pump airflow isvaried depending on outdoor temperature to maximize comfort.S EFFICIENCY -- fixed airflow used to achieve specified ratings --no dehumidification airflow reduction. This is nominally 350CFM/ton, but will vary if a 2--stage outdoor unit is used.S MAXIMUM -- 400 CFM/ton. Dehumidify features are not activewhen set to maximum.Dehum Airflow:S NORMAL (factory default) -- When equipment is running todehumidify, the airflow is allowed to adjust to a minimum tosatisfy the dehumidification call.S HIGH -- Minimum airflow during the dehumidify mode isincreased to reduce duct and register sweating. Also increasesminimum airflow during normal cooling operation to reduceduct sweating.Heater Size:S (choices dependent upon fan coil model)This will show the heater size entered during the start--up process.This value can be changed to another value (limited by the modelnumber of the fan coil). If the electric heater is self--identifying, thisvalue is not shown.Elect Heat LockoutS NONE (default)S +5 to 55_F / --15 to 18_COutside temperature above which the electric heat will not operateexcept for defrost.G TerminalThis setup option selects desired operation when the R--G circuit ismade on the fan coil control board.S DISABLED (Default)S FAN -- turns on fan to selected fan speed when G terminal isenergized. See Fig. 28.S FAN SPEED -- select Low, Med, High for all zones when Gterminal is energized.S SHUTDOWN -- shuts off fan and equipment when initiated.This function is not intended for emergency fire shutdown. Itmay be activated by a dry contact from an external device suchas a float switch or a relay. User selects whether the contact isNC -- normally closed (default) or NO-- normally open. UserInterface displays SYSTEM MALFUNCTION on screen andregisters G terminal shutdown event in Last 10 System Events.See Fig. 29.Setup -- Heat Pump / ACCooling Lockout:S NONE (default)S 45_F / 7_CS 50_F / 10_CS 55_F / 13_COutside temperature below which cooling will not be provided.Low Ambient Cooling:S NO (default)S YESSelecting YES will enable the low ambient cooling operation inthe outdoor unit. This setting is only available with communicatingoutdoor units and with Cooling Lockout set to NONE.For detailed sequence of operation, see outdoor unit installationinstruction.Entered Size:S (dependent on indoor unit model)Size of the outdoor unit entered during the start--up process. If theoutdoor unit is a communicating model, this value will not beshown. This size can be changed here but is limited to sizes that theindoor unit can handle.Defrost Interval:S 30 minutesS 60 minutesS 90 minutesS 120 minutes (default)S Auto--Defrost interval optimized by outdoor control (default forcommunicating HP)Time interval at which defrost cycles can occur on a heat pump.High Cool Latch:S NONE (default)S OnS 80 to 110_F / 27 to 43_COutside temperature above which only the high speed (of a 2--stageoutdoor unit) will run when cooling.High Heat LatchS OFF (default)S OnS 20 to 50_F / --7 to 10_C 2 --stage heat pump runs only highstage heating below a selectable outdoor temperature.
