The IMC controller can be set locally during commissioning to operate in either of two modes: remote zone sensor con- trol mode (with local or remote zone sensor), or remote thermostat control mode. Several application mode command values are recognized by either IMC mode, while some can only be used when the IMC is in the remote thermostat control mode. Common Application Mode Values Value Mode Description 0 $00 AUTO Heating or cooling. Default after reset. 1 $01 HEAT Heating only. 3 $03 COOL Cooling only. 6 $06 OFF Unit off. 9 $09 FAN ONLY No heating or cooling allowed. 255 $FF NUL Same as AUTO. 208 $D0 FAN AUTO Main fan (blower) auto. Default after reset. 209 $D1 FAN ON Main fan (blower) on. 216 $D8 EXHAUST AUTO Power exhaust fan auto. Default after reset. 217 $D9 EXHAUST1 ON 1st stage power exhaust fan on. 218 $DA EXHAUST1 OFF 1st stage power exhaust fan off. 219 $DB EXHAUST2 ON 2nd stage power exhaust fan on. 220 $DC EXHAUST2 OFF 2nd stage power exhaust fan off. 221 $DD EXHAUST ON Both stages of power exhaust fan on. 222 $DE EXHAUST OFF Both stages of power exhaust fan off. 254 $FE RESET Force controller reset. The four command groups (0−9), (208−209), (216−222), and (224−236, see below) are independent of each other. Se- lecting a command from one group does not affect any previously sent command from another group. Except for OFF and RESET, which also set FAN AUTO, EXHAUST AUTO, and heat/cool demand IDLE. AUTO is the default application mode input. When in a remote zone sensor mode, AUTO allows the IMC control to gen- erate heating and cooling demands based on zone temperature and zone temperature setpoint. Auxiliary functions such as dehumidification or emergency override (i.e. smoke mode) will still operate as needed. Also the blower and ex- haust fan functions operate. HEAT and COOL allow the servicing of only heating or cooling demands. These set a mode only, and do not generate a demand. Application mode OFF is a unit−disable state, causing the controller to become idle, and clearing all outputs and timers. All outputs are kept off while application mode is OFF. Since this is a complete unit−disable command, it should not be used to turn off heating and cooling demands as part of remote thermostat operation − use 224 IDLE for that purpose. See below. Application mode FAN ONLY disables heating and cooling operation. No effect on fan operation. Return to normal op- eration with AUTO, HEAT, or COOL. Application modes FAN ON and FAN AUTO are used to turn on the main unit fan (blower), or return it to automatic op- eration. Application modes for EXHAUST ON are used to turn on/off a power exhaust fan, or to return it to automatic operation. The IMC may delay up to 30 seconds before responding to an exhaust command. These commands apply to single−, two−, and variable-speed power exhausts. A variable-speed exhaust is enabled here, while the speed is adjusted using AO:128, the Exhaust Fan Capacity Input. Application mode RESET causes the system to reset itself and go through the controller’s startup and initialization rou- tines. This takes about 8 seconds in an IMC controller, during which time the analog and digital inputs are settling to correct values. The controller will return to AUTO operation. AUTO, FAN AUTO and EXHAUST AUTO are the defaults after reset. Corp. 0808−L6 04/09 Page 8 Application Modes Specific To Remote Thermostat Operation These values are only recognized if the IMC control is placed in a remote thermostat mode of operation (set locally dur- ing commissioning).

For $E0 the fan turns off after a fan off−delay. COOL2 and COOL3 are equivalent unless 3−stage cooling has been selected locally at the controller during commis- sioning. HEAT2 and HEAT3 are equivalent except in heat pump equipment types, when HEAT2 acts as �emergency heat", run- ning auxiliary strip heat and turning off the compressor(s). So in a heat pump, normal heating is commanded using HEAT1 or HEAT3. REHEAT LO and REHEAT HI can only be used if Supermarket Reheat is enabled for the IMC using ECTO 4.24. If a mode not defined in the above list is sent, then the application mode is not changed. ® When an IMC is commissioned for BACnet gateway remote thermostat operation, it will wait for 5 minutes following startup to receive application mode data. The IMC will remain in AUTO mode until data is received, or until the 5 minute period has expired. If 5 minutes passes without data being received, then the IMC will enter the backup mode of operation (set locally dur- ing commissioning). It is recommended that the application mode data be updated at intervals of no more than 2 minutes to be sure that a single missed−data event will not constitute an application mode data failure. Any application mode data will serve as a valid update; either common or remote thermostat values. If application mode data appears while the IMC is in a backup mode, then the IMC will reset and normal operation will resume.

Object Name: Space Dehumidification Setpoint Object Type: AO (Analog Output) Object ID: 108 Object Units: (98) Percent Value = 0 − 100 0−100: % relative humidity setpoint Dehumidification begins when the effective space relative humidity rises to this setpoint value. The default following re- set is local control. Once an executive controller has sent a setpoint for AO:108, there is no way to return to the local setpoint except by controller reset. Dehumidification ends when the effective space relative humidity falls below this setpoint value minus a dehu- midification deadband that is typically 3%. The deadband value is set locally during commissioning. Corp. 0808−L6 04/09 Page 10 Object Name: Temperature Setpoint (abs) Object Type: AO (Analog Output) Object ID: 109 Object Units: (64) Degrees−Fahrenheit Value = 36.25 – 100.00 degF, in 0.25 degF increments The single−point �Temperature Setpoint (abs)" (including offset; see below) is converted locally to occupied and unoccu- pied heating and cooling setpoints. The occupied and unoccupied heating and cooling setpoints are computed to be centered (if possible) on the effective single−point setpoint. This is done while preserving the occupied and unoccupied deadbands, as well as any local restrictions on minimum or maximum values. The default following reset is 70 degF, but local values are used for the heating and cooling (occupied and unoocupied) setpoints until a value is received for AO:109. As an alternative method of establishing setpoints, the individual setpoints AV:130−133 may be used. The IMC uses whatever were the last setpoints received, whether from AO:109−110, or AV:130−133. The occupied heat/cool auto−changeover deadband value is set locally during commissioning. The unoccupied heat/cool auto−changeover deadband value is set locally during commissioning by adjusting the back- up unoccupied heating and cooling setpoints. The difference between these setpoints will be used as the unoccupied heat/cool auto−changeover deadband value. Object Name: Temperature Setpoint Offset Object Type: AO (Analog Output) Object ID: 110 Object Units: (64) Degrees−Fahrenheit Value = −32.00 – 31.75 degF, in 0.25 degF increments A signed value added to the Temperature Setpoint (abs) value to provide an effective temperature setpoint. See above regarding deadbands and limits. The default following reset is 0. Object Name: Space Temperature Input Object Type: AO (Analog Output) Object ID: 113 Object Units: (64) Degrees−Fahrenheit Value = 36.25 – 100.00 degF, in 0.25 degF increments A network value for the space temperature. Heating and cooling demands are generated based on the �Space Temper- ature Input", and the �Temperature Setpoint (abs)" and �Temperature Setpoint Offset" values. See above. The default following reset is 72.5 degF. ® When an IMC is commissioned for BACnet gateway remote room sensor operation, it will wait for 5 minutes following startup to receive space temperature data. The IMC will remain in a no−run mode until data is received, or until the 5 minute period has expired. If 5 minutes passes without data being received, then the IMC begins to use local data for the space temperature. If a local sensor is connected then it will be used. If not, then a failed−sensor error is recorded and the IMC will enter the backup mode of operation (set locally during commissioning). It is recommended that network data be updated at intervals of no more than 2 minutes to be sure that a single missed− data event will not constitute a data update failure. If data appears after a sensor failure is processed, it will be treated as an intermittent sensor. Normal operation will re- sume. If the IMC is in a backup mode, then it will reset before resuming. ® IMC BACnet Module Page 11 Object Name: Emergency Override Control Object Type: AO (Analog Output) Object ID: 114 Object Units: (95) No_Units Value = 0 − 255 Set the emergency mode defined by value, decoded as: Supply Exhaust Outdoor Value Mode Fan Fan Damper 0 NORMAL auto auto auto 1 PRESSURIZE on off open 2 DEPRESSURIZE off on (speed) closed 3 PURGE on on (speed) open 4 SHUTDOWN off off closed 5 FIRE 6 DEPRESSURIZE off on (pressure) closed 7 PURGE on on (pressure) open >7 NUL (normal) auto auto auto auto − normal operation (speed) − exhaust fan runs at speed pre−selected at equipment (pressure) − exhaust fan runs to maintain building press setpoint; local or remote Mode 5, FIRE, is a locally defined operation (set at commissioning).
